Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.
Generally light winds, locally a bit stronger from the north
and northeast…with relatively cool weather into the middle
of this week
A couple of weak cold fronts/cloud bands will bring a few
showers to the north shores and slopes over the next several
days, then the chance of a more active cold front arriving
during the weekend…bringing locally heavy rains over
much of the state into early next week – first on Kauai

We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.
~~~ Hawaii Weather Narrative ~~~
Generally light to locally moderate breezes from the north to northeast today through Wednesday, bringing slightly cooler air into our area. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. Here’s a real-time wind profile of the central Pacific…centered on the Hawaiian Islands. ~~~ We find low pressure systems far northwest, north and northeast of the state, with their associated cold fronts trailing to the south. Meanwhile, we see a high pressure system well offshore to the northeast of the state…with an elongated ridge of high pressure extending west into the central part of the state. Winds will generally be on the light side, although locally a bit stronger from the north to northeast winds…keeping a slight cool edge to our area. We will find strengthening southeast winds later Thursday into Friday, then shifting further to the south and southwest into the weekend…ahead of a cold front.
Satellite imagery shows a weak cold front just to the north of Kauai, along with scattered low level clouds elsewhere…especially around the Big Island. Much of the rest of the state remains quite clear to partly cloudy, which should continue into Tuesday. Here’s the looping radar image, showing generally light showers over the ocean near the Big Island, with hardly any elsewhere at the time of this writing. Looking at this larger satellite image, which is in the looping mode, we can see generally clear to partly cloudy skies across much of the state, with clouds forming over and around the mountains locally. The frontal boundary may finally get close enough to bring a few showers to Kauai, although not likely much further into the state than that.
We’ll see the arrival of a couple of weak cold fronts during this first half of the week…bringing a modest increase in clouds and showers. Looking further ahead, the models are suggesting that a stronger cold front will approach the state from the northwest later Friday into the weekend. The front will bring showers (prefrontal showers) out ahead of it, and as the front pushes down through the state during the weekend into early next week. There are apt to be gusty winds coming up from the southeast through southwest ahead of this cold front. The models continue showing all the necessary ingredients for a period of showers, first on Kauai and Oahu, then down to Maui County…and finally the Big Island Sunday night into Monday. I’ll have more to say about this upcoming wet weather event as we move through this new week. I’ll be back early Tuesday morning with your next new weather narrative, I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.
Here on Maui, at the 3,100 foot elevation, at my upper Kula, Maui weather tower, the air temperature was 58.6F degrees at 610am on this Monday morning. The breezes are coming in from the north, and is triggering my wind chimes into action. I can see lots of stars twinkling above, as its still dark. Although, when I went out on my weather deck a few minutes ago, I could see some gray looking clouds over along the north shore, being carried this way…and over the West Maui Mountains too. As it gets lighter in a little while, I’ll come back and give you a better idea what’s happening with our weather here on Maui. It’s now 650am, and light enough for me to see clouds moving in over Maui, coming over us on the cool northerly breezes. These breezes are carrying a few light misty showers and drizzles locally through the Central Valley. Here in Kula, my weather deck is a bit wet from a few light showers.
~~~ It’s early afternoon at 1255pm here in Kula, under partly cloudy skies, light winds…with an air temperature of 69.4 degrees. The light misty showers that fell early this morning, are now long gone. There’s still a relatively chilly northern breeze, keeping the air temperature slightly lower than it otherwise would be. We can see that minor cold front just to the north of Kauai, using this looping satellite image. It’s difficult to know exactly what it will do, although it may just fizzle out, or at least be fairly insignificant in its influence over Kauai…and however much further it can migrate down into the state. The main thing is, that it won’t amount to much, in terms of rainfall for the state.
~~~ We’re into our early evening hours now, at 520pm, with slightly chilly north breezes, partly cloudy skies, and an air temperature of 65.8 degrees. It was a beautiful day in my opinion, with that delightful coolness to the air, although the sun remained tropically warm at the same time. It was dry just about everywhere in the state, with just a few drops down on the Big Island locally. The cold front just north of Kauai isn’t very robust, which is an understatement. It may be able to inch its way southward towards Kauai, although then again…it might peter out before arriving just as easily. We’ll have to wait until tonight into early Tuesday morning to see just how far into the tropics it can make its way. Now at 650pm, the temperature has fallen quickly to 60.4 degrees. Now, at 820pm, the thermometer has dropped to 56.8 degrees, while I make this update in my turtle neck long sleeve shirt…and thick down vest. It won’t be long before I crawl under my warm down comforter, with a thin fleece blanket on top of that…maybe I’ll even wear my wool socks to bed tonight!

Interesting: Is Weird Winter Weather Related to Climate Change? – This winter’s weather has been weird across much of the Northern Hemisphere. Record storms in Europe; record drought in California; record heat in parts of the Arctic, including Alaska and parts of Scandinavia; but record freezes too, as polar air blew south over Canada and the U.S., causing near-record ice cover on the Great Lakes, sending the mercury as low as minus 50 degrees Celsius in Minnesota, and bringing sharp chills to Texas.
Everyone is blaming the jet stream, which drives most weather in mid-latitudes. That would be a significant development. For what happens to the jet stream in the coming decades looks likely to be the key link between the abstractions of climate change and real weather we all experience. So, is our recent strange weather a sign of things to come? Are we, as British opposition leader Ed Milliband put it this month while surveying a flooded nation, “sleepwalking to a climate crisis”?
The story gets tangled because trying to identify long-term trends amid the noise of daily weather is hard.
The U.K. Met Office, which keeps a global weather watch, said in a rush report put out in mid-February that we are experiencing a “hemispheric pattern of severe weather,” and that the events are linked. The most extreme days of the U.S. cold event, for instance, coincided with some of the most intense storms over the U.K. And physically the connection is through the polar jet stream, which the report said showed a “persistent pattern of perturbations” — in other words, it ran wild.
The polar jet stream is a narrow stream of fast wind circling the globe from west to east at the top of the troposphere from 7 to 12 kilometers up, and usually between 50 and 70 degrees north. It forms where cold, dense air from the Arctic meets warmer and less dense air from mid-latitudes. At the boundary, winds rush in to equalize the pressure difference. The earth’s rotation diverts these winds to travel eastward.
As the jet roars around the world, it drags weather systems with it. Most of Europe’s weather rides in under the jet stream from the Atlantic, and most of the western U.S.’s weather comes from the Pacific in a similar manner.
