Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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 Saturday comments: I’m here at my friend Linda’s place in Corte Madera, CA

Good day everyone, I hope you have a great Saturday wherever you happen to be spending it.

405am, it’s a clear morning, with a low temperature of 46 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Breezy east to east-southeast winds will continue to gradually ease through early next week. A plume of moisture will produce passing showers across windward and mountain areas through today.

A drier weather pattern is expected Sunday into early next week, with light to moderate east to east-southeast winds. Winds should be light enough for sea breezes to develop during the day and land breezes at night, especially early next week.

Hawaii’s Weather Details: Satellite and radar imagery shows light to moderate showers along windward and mountain areas, with some showers making it leeward, especially for Kauai County. Shower activity is expected to trend down along windward zones. Leeward areas will see a increase in clouds and showers this afternoon, as sea breezes develop.

Gentle to breezy east to east-southeast winds appear to have developed over the state. A ridge of high pressure north of the island chain will shift south, further weakening and veering winds out of the east-southeast, especially over the western half of the state.

Breezier winds will persist along windward areas, and lighter winds will develop along leeward areas today as a result. A drier air mass is expected to move in by Sunday, so overall we should fewer showers Sunday, as well as lighter winds with sea breezes developing over many leeward areas Sunday afternoon.

For early next week, high pressure will be centered far northeast of the state, while a low pressure system shifts north of the state. We will continue to be in a hybrid wind pattern early next week, with light to breezy east-southeast winds over windward areas, and generally light winds over leeward areas.

Due to limited moisture, don’t expect much rainfall early next week, but some light passing showers should be expected over windward areas, as well as some light showers over leeward areas during the afternoons, with the sea breezes developing.

For the second half of next week, models continue to show a some discrepancies between the ECMWF and the GFS. The ECMWF shows a much deeper upper level trough, with a surface trough developing near the state. This setup would continue the hybrid trade wind and land/seabreeze pattern.

Meanwhile, the GFS shows a much weaker upper level trough with the high north of the state, with strengthening trade winds during the second half of the week. The forecast favors the GFS model for now, but will likely change over the next several days…as model guidance narrows on a solution.

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

Marine Environmental Details:  A high well northeast of the state, and low well northwest of Hawaii is producing east-southeast winds over the western half of the state, and moderate to locally strong easterly winds over the eastern half of the state. Winds will weaken slightly over the next few days, as the high weakens and the low shifts north of the state.

A Small Craft Advisory (SCA) will remain in effect for most waters and channels surrounding Big Island, Maui, and Molokai. The advisory may be scaled back late this weekend, as winds weaken and shift out of the east-southeast.

Surf heights will remain below advisory thresholds for all shores. A small northwest, medium period swell is forecast to subside tonight. Thus, small surf can be expected along north and northwest facing shores through the remainder of the weekend.

Breezy trade winds will produce choppy, rough surf along east facing shores through at least tonight. Conditions are expected to improve on Sunday. Meanwhile, expect small surf along south and southeast facing shores with occasional pulses.

Interesting:  Climate Change Intensified 2021 Pacific Northwest Heat Wave, Study Finds

 

Climate change made the disastrous 2021 heat wave in the Pacific Northwest larger and longer-lasting than it would have been otherwise, a new study finds.

From June 18 to July 14 of 2021, high pressure trapped heat over the region, forming a “heat dome.” For 27 days, the mercury regularly surpassed 100 degrees F, at one point reaching 121.3 degrees F in British Columbia, the hottest temperature ever recorded in Canada. In total, the heat wave killed more than 1,400 people in the U.S. and Canada.

Prior research has shown that global warming made the 2021 heat dome 150 times more likely. The new study, published in Communications Earth and Environment, found the heat dome was also 34 percent larger and lasted 59 percent longer as a result of climate change.
