Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Thursday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear with clouds along the windward side here in Maui County this morning. The low temperature here at my place was 53 degrees.

It’s turned very sunny this afternoon, and as such, it feels very warm here in upper Kula, a bit too warm for my liking.

907pm, and our skies here on Maui are clear to partly cloudy with a few exceptions. All the sunshine during the afternoon hours drove the high temperature up to 80 degrees. At the time of this writing the temperature dropped to a cooler 60.9 degrees.

—Forecasters within NOAA’s National Weather Service predict above-normal hurricane activity in the Atlantic basin this year.

Weather Wit of the day:  Outstanding Weather – When you’re outstanding in the cold, wind and rain

 

Hawaii’s Broad Brush Weather Overview:  An upper low near the state will bring a slight chance of thunderstorms through Friday. High pressure to the north will drive breezy trade winds and mostly windward showers. A decrease in trade showers with drier conditions persisting into the middle of next week.

Hawaii’s Weather Details:  A high is centered far north of Hawaii, but is driving breezy trade winds across the islands. Satellite imagery shows an upper low just north of Kauai slowly moving southeastward. Radar and satellites show widely scattered low clouds and showers moving in from the east carried by the trade winds, with the upper level feature providing a little bit of enhancement to the showers.

Most of the instability is focused above the trade wind inversion, which has been the limiting factor for thunderstorms. There will continue to be a chance for isolated thunderstorms around Kauai and Oahu tonight and Friday, and the Big Island interior Friday afternoon due to the sea breeze/instability combination.

The upper low will remain in the vicinity of Kauai and Oahu tonight, then begin to lift northeastward Friday allowing warming and stabilizing aloft by Friday night. Other than the thunderstorm chances, a wetter than normal trade wind pattern should prevail during the next couple days, favoring windward and mountain areas, along with more leeward spread to the shower activity.

The surface high will maintain the breezy winds through the weekend, before weakening and sliding closer to the state Memorial Day through the middle of next week, resulting in an easing of the trade wind flow back to moderate speeds. The airmass will further stabilize and dry out over the state this weekend, leading to a decrease in trade showers, with drier conditions persisting into the middle of next week.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  A broad ridge of high pressure will remain nearly stationary north of the state, maintaining moderate to locally strong trade winds through the weekend. An upper level low will build over the northern waters, enhancing trade showers and may produce isolated thunderstorms, mainly over Kauai and Oahu waters, through Friday. The Small Craft Advisory for the windier waters and channels around Maui County and the Big Island has been extended through Friday, and now includes windier waters around Kauai and Maui County, as winds are expected to strengthen slightly.

Surf along south facing shores will remain small to moderate as a long period south-southwest swell is expected to fill in. A second pulse from the same direction will fill in over the weekend, keeping small to moderate surf through the weekend, before declining early next week.

East shore surf will remain near seasonal average during the next couple of days as trade winds persist. Tiny surf will prevail along north facing shores this week into the weekend.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:  There are no active tropical cyclones

South of the Southern Coast of Mexico:

>>> An area of low pressure is likely to form early next week several hundred miles south of the southern coast of Mexico. Conditions appear favorable for development of this system, and a tropical depression could form around the middle of next week while moving westward to west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…60 percent

Interesting:  How Climate Change is Changing Your Favorite Wine

If you drink wine, chances are it already tastes different—rising global temperatures are transforming wine growing regions around the world.

A major global study led by UBC researchers reveals that temperatures during the growing season have increased globally across the major wine regions. On average, regions have warmed by the equivalent of almost 100 extra growing degree days (GDD)—a measure of the cumulative heat that vines are exposed to, influencing their growth and ripening.

“Europe is feeling the biggest impact, with parts of the continent heating up by as much as 2.5°C since 1980. That kind of change can affect harvest times, grape ripening, and thus the taste of the wine,” said Dr. Elizabeth Wolkovich, senior author of the study and an associate professor at UBC’s faculty of forestry.
