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 Saturday comments:  I’m here in Corte Madera (Marin County, CA) at my friend Linda’s, with another friend Bob Earle from Bend, Oregon.

It’s clear to partly cloudy with a low temperature of 44.4 degrees.

Weather Wit of the day: Now the people who were flooded are really upset. The IRS raised their taxes because their property has become waterfront.

Hawaii’s Broad Brush Weather Overview:  Light to locally breezy trades with generally drier weekend weather. There are increasing chances for more inclement, more active weather next week.

Hawaii’s Weather Details: Broad upper ridging west of our area will expend eastward, and envelope the Hawaiian Islands and its surrounding waters. A 1029 millibar high pressure located approximately 1,200 miles from Oahu, is weakening and settling southeastward. Atmospheric soundings are depicting very dry mid level air moving in from the east. All of these factors equate to an evolving stable weather pattern, and will result in drier weather under lighter winds. This drier air mass will move across the area early today and assist in ending the overnight persistent windward Big Island precipitation, where many rain gauges in the Hilo and Puna Districts have picked up 2 to 5 inches of rain since early Friday morning.

A nice trade wind pattern weekend under partially sunny skies and light trades, locally breezy within higher terrain. Light precipitation will focus along windward upslope mountains, with higher rain accumulations within an overnight relatively deeper moistened boundary layer squeezed underneath a thick layer of dry air aloft. The next couple of days will be the best weather days of the upcoming week.

A weakness will develop within the upper ridge over the islands on Monday. An upper trough and associated cold front will approach the island chain from the northwest going into Tuesday. It is a bit early to determine the evolution of this trough, but it will more than likely pull up moist equatorial air while destabilizing the regional atmosphere. The trough or upper low will increase the probabilities of isolated thunderstorms across the central islands of Oahu and Maui County from late Monday through Tuesday afternoon. Numerous showers that may produce locally heavy rain will be the main theme Monday through Wednesday.

Freezing levels falling to around 12,000 feet, implies a frozen mix atop Big Island’s summits. Mid level winds will strengthen east of the upper trough axis going into mid-week, and this may increase Haleakala and Big Island summit winds to near wind advisory in gust Monday night and Tuesday.

The cold front will slow as it approaches the western half of the state Wednesday. This feature, along with a mid level trough moving across from the east within a highly moistened regional air mass, should provide the necessary ingredients of lift and instability to possibly prolong this wet pattern into next weekend.

Fire weather:  Recent island wide rain and more overcast skies, along with relatively higher minimum afternoon humidities under light winds, will all help maintain a lower fire weather threat. The potential exists for a wet weather pattern through most of next week. The lower inversion height slopes from near 4,000 feet over the western islands, to around 9,000 feet on Big Island.

Hawaii’s Marine Environment:  Moderate to locally strong easterly trade winds will persist, and gradually weaken as high pressure to the northeast slowly drifts southeast and weakens. A Small Craft Advisory (SCA) has been trimmed back to the typical windy waters and channels around Maui County and the Big Island. Guidance for early next week remains uncertain, with the potential for an upper level trough forming southeast of the coastal waters Monday and moving northwest over the islands.

The moderate trade winds may veer to the east-southeast and slowly weaken through Tuesday. Additionally, a front looks to move into the offshore waters by Tuesday afternoon, bringing locally strong east-northeast winds behind the front, before weakening over the coastal waters mid-week. There is a potential for isolated to scattered thunderstorms over the marine waters Monday through Wednesday.

Surf along north facing shores will remain small before a small to moderate, medium to long period northwest swell looks to fill in that will keep surf elevated through the weekend. A moderate long period northwest swell is expected to arrive late Tuesday, and peak Wednesday near High Surf Advisory (HSA) levels, before declining by the end of next week.

Surf along east facing shores will continue to decline through the weekend, due to the weakening of the local and upstream trade winds. Large choppy short period surf for north and exposed east shores is possible by the middle of next week depending on the evolution of the potential trough and approaching cold front mentioned above. For south shores, tiny background southerly swell will remain through the forecast period.

Interesting:  In a Death Valley Shrub, Scientists See a Blueprint for Heat-Proof Crops

In the searing heat of Death Valley, California, a small desert shrub, Tidestromia oblongifolia, is able to thrive in temperatures upwards of 120 degrees F. A new study reveals how the plant can endure in such harsh conditions, findings that could prove useful in engineering crops to endure more extreme heat.

For the study, scientists recreated the withering heat and intense sunlight of Death Valley summers in the lab, subjecting the seeds of T. oblongifolia and other plants to the brutal conditions. They found that while other desert plants stopped growing, T. oblongifolia actually grew faster, tripling its mass in just 10 days.

“When we first brought these seeds back to the lab, we were fighting just to get them to grow,” said Karine Prado of Michigan State University. “But once we managed to mimic Death Valley conditions in our growth chambers, they took off.”
