Aloha Paragraphs

Artist: George Young

The well established upper level low pressure system remains positioned to the NW of the main Hawaiian Islands now. The location and depth of this upper low will keep our local weather rather shower prone Saturday. It remains quite evident though, that the resultant precipitation will be most focused during the afternoon hours around the mountains. Our winds are blowing from the SE over most areas of the state today, helping to bring volcanic haze up from the vent on the Big Island. There will be high cirrus clouds streaming up over the islands too, dimming our sunshine at times.


This upper low, with its associated cold air aloft, will keep our overlying atmosphere unstable Saturday. This means that whatever clouds that develop with the daytime heating, will be allowed to grow considerably in the vertical dimension. These mostly afternoon cumulus clouds will have towering aspects to them, and very likely drop some decent showers. The daytime heating of the islands will be the triggering mechanism for these big cloud forms.


The mornings in most areas will start off quite clear, giving the appearance of a great day coming up. However, as is often the case over tropical islands, clouds will grow during the second half of the day. So, it might be wise to hit the beaches, and do most of your outdoor activities during the beautiful morning hours. The afternoons, especially in the upcountry interior sections, may very well receive a pretty good rain shower! Clouds will generally collapse after dark, with returning clear skies into the next morning.


The Island of Kauai, which will be closest to the low pressure system, will have the best chance for the heaviest and most generous showers. The other islands will see afternoon cloud buildups too, although with likely somewhat less wet conditions. The above described weather scenerio will take us through today. As we get into Sunday and Monday, the upper low is expected to depart our area. Weather conditions are forecast to improve then, with light trade winds returning for a couple of days.


It’s early Saturday evening here in Kula, Maui.
 The day began clear enough, although skies quickly became filled with a thick layer of high cirrus clouds. The source of these sun dimming cirrus clouds was the trough of low pressure located near the islands. These clouds gave an overcast character to the day, muted even more where there was considerable volcanic haze…like here on Maui. I stayed home most of the morning, visiting with a friend. I pryed myself out of the house this afternoon, down to Paia for a shopping spree at the health food store. I was in the mood to head right back up the mountain, after a quick stop in Pukalani for some Ahi Poki. There were a few spits of rain a little while ago, however it didn’t really let loose. The cloud cover certainly felt and looked moisture laden, although nothing heavy fell here in Kula. I have a good book to read this evening, and plan to kick back with it. I hope you have a great Saturday evening/night, either hanging at home, or out on the town. I’ll be back Sunday morning for additional weather updates. Aloha for now…Glenn.

Beautiful Wave!


The well advertised upper level low pressure system has positioned itself to the NW of the main Hawaiian Islands now.
I say well advertised, as the computer forecast models locked onto this late last week, and have held on tight ever since. The location and depth of this upper low will keep our local weather rather shower prone. It seems quite clear though, that the resultant precipitation will be most focused during the afternoon hours around the mountains.


This upper low, with its associated cold air aloft, will keep our overlying atmosphere unstable into Saturday. This means that whatever clouds that develop with the daytime heating, will be allowed to grow considerably in the vertical dimension. These mostly afternoon cumulus clouds will have towering aspects to them, and very likely drop some decent showers.

The other islands will see afternoon cloud buildups too, although with likely somewhat less wet conditions. The above described weather scenerio will take us through Saturday. As Sunday and Monday rolls around, the upper low is expected to depart our area of the north central Pacific. Weather conditions are forecast to improve then, with light trade winds returning for a couple of days.

It’s Friday late afternoon here in Kahului, Maui. I’m writing a few words from my web service providers office, bumpnetworks.com. They have a wonderfully large set of picture windows, with a dynamic view of the Haleakala Crater. It isn’t visible however, as there are lots of heavy duty cumulus and towering cumulus clouds hiding the bulk of the mountain. I can sit here and see rainbows, and lots of showers falling up there. I’m going to Borders Books for a while after this, and then meet a friend at one of the local theaters to see a film. The name of this film is Brokeback Mountain I believe, which received lots of hype…I’ll let you know what I think of it in Saturday mornings narrative update. I got to the beach again today at lunch, which was a special experience as usual. There were no waves to bodysurf, although the warm sand on my feet, and the warm ocean on my skin felt great! I hope you have a great Friday night. Aloha for now…Glenn.

Aloha Paragraphs



Vintage Waikiki Sunset

An unsettled weather pattern will influence the Hawaiian Islands through Saturday. The details include a surface trough of low pressure moving from east to west over us, while an upper level trough will be forming to the NW of Kauai by early Friday. The interaction between these two weather elements will keep our local atmosphere unstable and more than normally shower prone. Meanwhile, light east to SE winds will be blowing across the Aloha state.


The surface trough’s journey across the islands Thursday will bring variable clouds, along with showers at times. The bulk of this moisture will be deposited around the mountains, and along the windward coasts and slopes. As the upper trough develops Thursday night into Friday, it will bring cold air aloft…triggering a greater degree of instability. Cold air up high, and warm moist air near the surface, is the perfect recipe for locally heavy showers.


These rain cells may cause some localized flooding Friday into Saturday.
It should be noted that this is a rather complicated weather situation, and it’s still not completely clear about how this will all unfold. It may turn out to be a fairly widespread rain event for a couple of days, or it could be more like isolated heavy showers or a thunderstorm popping up here and there. It will become more clear once the upper low forms by Friday. However, in general, look for showery weather Thursday through Saturday at times.


The latest computer forecast models indicate that the upper trough, along with its surface reflection, will move west on Sunday.
This suggests that it will take its inclement weather aspects with it. This is good news, in that it will leave improved weather conditions for the last 2/3 of the upcoming three day holiday weekend coming up! Sunday and Monday look to be drier, and more favorably inclined. Next week on the whole looks to be pretty nice, although its too early to cement that prospect into place just yet.


It’s Thursday evening here in Kula, Maui.
 I just got back from having a very productive meeting with my web folks, also known as bumpnetworks.com, they are very good at web hosting and serving their clients. At any rate, I continue to add new features, and to make it as useful a website as I possibly can.  I’m going to talk more about it when I have time, although for now just say that I’ll be initiating my annual fund raiser soon. In addition, there is now an opportunity for businesses to put their link on my pages, located on the left hand margin (under the search feature). Let me know if you have interest in putting a link to your webpage. For now though, I’ve got to go down and grab a little dinner before by 9pm bedtime arrives. I hope you had a great Thursday, and that you’ll meet here Friday morning, for the next completely updated Aloha Paragraphs. Be well until then…Glenn.

Another beautiful Kauai Beach

The Hawaiian Islands remain in a slot between high pressure to our NW, and low pressure to our east Wednesday. The net result so far this week has been cool NE breezes, along with quite a few passing showers along the windward sides of the islands…and around the mountains in places too. This weather pattern has kept us somewhat cooler than usual, with a slight winter nip in the air.

Weather maps now show the low pressure trough to our east moving westward towards Hawaii. This will bring a couple of changes in our local weather picture. First of all, the winds will begin to get lighter, and come to us from an easterly direction. This in turn will help to bring back noticeably warmer weather. At the same time, with the trough moving over us, we will see some showers falling along our windward sides, with a few light showers in some leeward spots through Thursday.


The information above seems fairly straight forward, and will probably happen.
However, as we get to Friday, and the upcoming weekend, things get a little tricky. The computer forecast models have continued to give us varying ideas of what will happen. There isn’t a clear cut outlook in terms of forecasts for the extended forecast period. Usually the models are more aligned in their prognosis, but this time around there is quite a bit of uncertainty.


Let me lay out the choices here: either dry or rainy…at least it’s quite clear in that regard!
Cool The models describe a low pressure system to the west of the state. These are often called Kona low pressure systems. These Kona lows can bring lots of heavy rain, and even thunderstorms. Although, it all hinges on where they form, how far from the islands they are, etc. In this case, it’s still too early to know for sure. So I think we’d better just hold this prospect lightly, and give the models another day or two, before we say one way or the other.


It’s early Wednesday evening here in Kula, Maui.
 It wasn’t what I call a banner day in terms of sunshine today. There were those infrequent sunny periods, however they were rather brief, and far between. We might call such a day variably cloudy, and there were a few showers around too. I made it to the beach, although just took a walk, and skipped the ocean dip. I felt a little guilty with myself, in not taking the plunge. It was cool and breezy, and I just didn’t want to do it, so I didn’t. I’m always kinda of proud, when I can give myself a little slack here and there, as I’m quite heavily into my routine…as may be rather clear to you regular readers. I have a meeting with my web person tomorrow after work, and I’m looking forward to making this website even more crisp, and easier to use. By the way, thanks so much everyone for your comments, or replies to my commentaries, they help me to fine tune what you want to see…and they are encouraging! I’ll be back first thing Thursday morning, have a good night. Aloha for now…Glenn.

Aloha Paragraphs


Happy Valentines Day!

The Hawaiian Islands are located between a high pressure ridge to our NW, and a trough of low pressure to our east. This pressure configuration puts a NE wind flow across our area of the central north Pacific. NE winds bring air into the state from more northern latitudes, thus the cooler temperatures of the last few days. This chilly reality will continue today, with temperatures taking a turn to the warmer side Wednesday and Thursday. The winds will eventually become SE by Friday into the weekend, bringing a total end to our tropical cool snap.

The latest computer forecast models bring the trough, located to our east, westward over the Hawaiian islands during the next couple of days. This in turn will cause our local winds to calm down in strength, and take a turn to the east. There may not be very much of an influence as this trough moves overhead. Although, there may be some increase in showers along our windward sides. Sound a little wishy washy do I, well, there is a measure of uncertainty, and it may take another day or so to be sure whether or not the showers will increase then or not.

A little further down the road, this trough will edge over to the west of the islands. This will pose a more pronounced threat of showers. At the same time, a pool of cold air will slide over the state too, causing at least some degree of instability in our local air mass. It appears that there will at least be some showers around, although the way it looks from here, the bulk of that moisture will be taking aim on the windward coasts and slopes of the individual islands.

It’s early Valentines Day evening, here in Kula, Maui, Hawaii. When I left Kihei after work, it was 75F degrees, and now about an hour later, it’s 59F here at home. I can hear a cock Pheasant calling in the distance, I like his quick qwak, qwak. I ran into a little shower coming up through Pukalani, and I can see that it showered here recently as well. A friend called from Haiku this afternoon, and she said it had been raining off and on today, some of which had been quite heavy. I made it to the beach today at lunch, and enjoyed that time out in nature, although I must admit the water was chilly when I first dove in. I had a couple of Valentines invitations for dinner, and yet what I most felt like doing was coming home. I have a new novel I’ll be starting, and I’m looking forward to cracking that open after dinner. I hope you had a lovely day, on this especially romantic holiday! I’ll be back early Wednesday morning with the next narrative, be well until then my friends. Aloha for now…Glenn.

Aloha Paragraphs

 

A trough of low pressure aloft and at the surface during the last 24 hours, has kept our atmosphere relatively unstable. This instability caused showers to form over and around the islands, some of which were locally quite heavy. There weren’t any intense showers though, with no reports of flooding on any of the islands…although the Big Island will likely see the most showers around Monday. The low pressure system is moving away towards the east, with the rest of the state from Maui westward finding improving weather.


As these troughs move away, our weather will settle down for the time being, at least in most areas.
At the same time, weather maps show a high pressure ridge to the NW of Hawaii. The orientation of these low and high pressure systems, will bring cool NE trade winds back into the state through Tuesday. This wind alignment will keep some clouds and showers passing over the windward sides of the islands. The leeward sections will see more sunshine, with just a few showers on the smaller islands.


The weather outlook remains somewhat complex, with a degree of uncertainty involved with this weeks forecast.
The latest computer forecast model output shows the trough to our east, retrograding back westward, to near the islands around mid-week. This would bring back the threat of showers to our area Wednesday and Thursday. Those same models go on to show a Kona low pressure system forming towards the weekend. Depending upon where this low forms will help determine where any associated rain would fall…still a bit too early to know quite yet.


Weather conditions during the winter month of February can change more dynamically than during the summer months.
Thus, the uncertainty surrounding the exact weather conditions this week. There’s a decent chance that we could get some more rainfall at some point, although it’s not totally clear when. Perhaps the best chances, from this vantage point, would be Wednesday and Thursday, and then again this coming weekend. Things may change, so we need to remain a bit more flexible than usual, as these possibilities sort themselves out.

It’s early Tuesday morning here in Kula, Maui. I just got through composing 45 minutes of new weather narrative material, which I was trying to copy and paste into this space. However, the battery on my laptop went dead just at that moment…and I lost it all! I couldn’t believe that happened, and now have yesterday’s information above. I’m sorry about this! I’ll try and find some time to write out something a little later this morning, please check back then. By the way, Happy Valentines Day! Aloha for now…Glenn.

Lihue, Kauai – 79F degrees
Honolulu, Oahu -78
Kaneohe, Oahu – 75
Kahului, Maui – 81
Hilo, Hawaii – 74
Kailua-Kona, Hawaii – 82

Temperatures early Sunday morning ranged between these warmest and coolest spots near sea level at the 5 a.m. hour:

 

Kailua-kona – 71
Molokai airport – 59

 

Precipitation Totals — The following numbers represent the largest precipitation totals during the last 24 hours (as of Sunday morning) on each of the major islands, including:

 

0.25 PRINCEVILLE AIRPORT, KAUAI
0.27 LULUKU, OAHU
0.00 MOLOKAI
0.00 LANAI
0.00 KAHOOLAWE
0.46 HANA AIRPORT, MAUI
0.85 PAHOA, BIG ISLAND

 

Weather Chart — Here’s the latest (automatically updated) weather map…a cold front is approaching from the NW, which is pushing a high pressure ridge closer to the state, with resulting lighter winds today into Monday…becoming gusty from the north to NE after the frontal passage later Monday. Here’s a Weather Map Symbol page for clarification about what all those funny weather sympbols mean.

 

Hawaii’s Mountains — Here’s a link to the live webcam on the summit of near 14,000 foot Mauna Keaon the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two webcams are only available during the daylight hours here in the islands…that is unless there’s a big moon rising just after sunset for an hour or two!

 

Satellite Images — To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Imageof the islands to see all the clouds around the state. This next satellite image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible satellite image. The next satellite image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean…out from the islands. To help you keep track of where any showers may be around the islands, here’s the latest radar image.

 

 

Aloha Paragraphs

 

Kauai

 

 

I am having considerable trouble with some of my webpages at the moment. I hope to have some resolution soon, however, until then, please bear with me, as I am working with my website provider to correct the situation. 

 

We have an upper level trough of low pressure moving over the islands now. This will provide the impetus for an unstable atmosphere. This in turn will make our overlying air mass shower prone today into Monday. As the coldest upper air temperatures arrive later Sunday, at the same time as the greatest daytime heating, we will see considerable clouds forming. These cumulus clouds may take on the form of towering cumulus, or even cumulonimbus…also known as thunderstorms.

 

Therefore, we may see locally heavy showers later Sunday into the night. There may be some localized flooding and ponding of roadways, so that caution should be exercised in terms of driving. This upper trough of low pressure is forecast by the latest computer forecast models to wobble around the island area for most of the new week ahead. Depending upon where this low is situated, will greatly determine where and when we see periods of rainy weather…some of which could be very heavy by next weekend.

 

Starting later Monday we’ll see the local winds coming out of the north and NE. This wind direction brings chilly weather to the islands. So look for a new period of cooler than normal weather, similar to what we saw last week for several days. As we move into the middle of the new week ahead, our winds will become SW. These kona winds will be warmer, although may bring a new threat of rainy weather towards the end of the week as noted above.

 

It’s early Sunday morning here in Kula, Maui. I’ve been up for a long time trying to fix the pages on this website. I’ve finally cleaned up this page, at least for the moment. I am no expert in this department, working with html code and stuff, so it is very tedious and time consuming. I hope to have time to work with the rest of the pages during the day today. At any rate, Sunday is starting off nice enough, although there are definite signs that we’ll be getting cloudier and locally wetter later today, as described in the paragraphs above. The current weather reality here in the central Pacific Ocean is unusually complex. As I glance around in my chair, there’s the huge almost full moon of February sinking down in the western horizon! It has certainly been keeping our night skies well lit up the last several days. I’ll be back later for more weather updates, and a sunset commentary too. Aloha for now…Glenn.

 

 

Air Temperatures — The following maximum temperatures were recorded across Hawaii Thursday:

Lihue, Kauai – 76F degrees
Honolulu, Oahu – 75
Kaneohe, Oahu – 75
Kahului, Maui – 77
Hilo, Hawaii – 78
Kailua-Kona, Hawaii – 82
Temperatures early Friday morning ranged between these warmest and coolest spots near sea level at the 4 a.m. hour:

Lihue, Kauai – 71
Kalaeloa, Oahu – 62
Precipitation Totals — The following numbers represent the largest precipitation totals during the last 24 hours (as of Friday morning) on each of the major islands, including:

0.24" MOUNT WAIALEALE, KAUAI
0.04" MANOA LYON ARBORETUM, OAHU
0.01" MOLOKAI
0.00" LANAI
0.00" KAHOOLAWE
0.46" WEST WAILUAIKI, MAUI
0.18" KAMUELA, BIG ISLAND

Weather Chart — Here’s the latest (automatically updated) weather map…a cold front is now to the easat and SE of the Big Island. A new 1027 millibar high pressure system is following closely behind the front. This will keep locally strong and gusty cool north to NE winds around today, becoming more typical trade winds Friday. Here’s a Weather Map Symbol page.

Aloha Paragraphs

The windward side of Oahu

The cool blustery NNE winds of late are gradually shifting around to the ENE. This turning in the wind direction will help to warm things up here in Hawaii, which has been locked in a tropical cold snap for the last several days. High temperatures have been restricted to the 70F’s for the most part, even at sea level locations. The upcountry areas, those higher elevation sections on Maui and the Big Island, haven’t even made it into the 70F’s during the days, since the most recent cold front swept through the island chain earlier this week.

Low temperatures have slid down into the upper 50F’s to the 60F’s in those coolest places near sea level, or within a couple hundred feet of sea level. There’s been an added coolness brought by the wind chill factor, presented to us by the blustery north to NNE breezes too. Thus, February, the coolest month of the year in Hawaii, is holding to its climatological norm. The overlying air mass has remained dry and stable, with low dew point temperatures…further adding to the chill. The mountain tops have been freezing, below freezing on some of the summits, with lots of snow on the Big Island mountain tops.

Most folks will be happy to learn that we are definitely turning the corner on this cool reality. As the winds get back to our normal trade wind direction, the atmosphere will start to feel warmer. We’ll begin this transition Friday, with Saturday and Sunday feeling noticably warmer. There will be more moisture in the air too, which will help to take the edge off the crispy conditions that have prevailed the last several days. Days will be warm and sunny to partly cloudy along the leeward coasts, with partly cloudy conditions on the windward sides with a few showers.

I hestitate to draw this to your attention in some way, although as a weatherman, I must point out what’s what. The latest computer forecast models continue to show the next cold front advancing in our direction. It won’t arrive until later Sunday, leaving most of the upcoming weekend in fine shape. The frontal cloud band will arrive on Kauai later Sunday, and then pass down through the rest of the state that night into Monday. The cold front will bring an increase in clouds, and some showers too. It’s still not clear about how much rain it will bring, which will have to be clarified over the next day or so…I will get back to you on that shortly.

Looking further ahead, the computer models are trying to spin up a low pressure system to the east of the islands. They show it moving northward, and then westward, and then southward. This would take it on a loop around the state. Again, it’s unclear exactly what this Kona low will do. We could see another cool snap on Monday, as our winds come in from the north after the cold front goes through. There’s a chance we may have more wet weather next week, although it all depends on where this low pressure system forms, and then where it moves from there. We’ll have to monitor this situation, as it could bring lots of rain, or not much at all…depending on where it “sets up shop”.

It’s early Friday morning here in Kula, Maui. Glancing over at my thermometer, the outdoor sensor is reading 41.5F degrees. This is the coldest temperature that I’ve had this winter, and actually in more than a year! As you can imagine, I’ve got on every bit of winter clothing that I have available. The only things sticking out into the cold air are my finger tips, and my face…fortunately I’m warm enough. Just for contrast, the Kahului airport, about 22 minutes drive down the mountain, at the same time, was reporting a warmer 64F degrees. Even warmer than that was the balmy 70F degrees at Lihue, Kauai. Wow, it’s incredible how cold it is at the time of this writing! I know most of you can’t relate to this, however weather extremes are exciting to me. I’ll be back later with more weather updates, and between now and then, I hope you have a great Friday! Aloha for now…Glenn.
