Hawaii’s MountainsHere’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 Sunday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, while the low temperature was 51.5 degrees.

834am, it’s a beautiful day here on Maui, with almost 100% cloud free skies!

Weather Wit of the day:  Snow – Chilly Powder

 

Hawaii’s Broad Brush Weather Overview:  A cold front and prefrontal cloud band will produce a 24 to 36 hour period of unsettled wet weather over the western Hawaiian Islands. Thunderstorms and localized flooding are possible threats with this next system for Niihau, Kauai and Oahu, from this evening through the Monday time period.

The frontal band will stall and diminish near Oahu from Monday night through Tuesday, as more stable easterly trade winds return, with periods of windward and mountain showers lasting through Wednesday night.

By Thursday, a strong ridge aloft will build in over the state, producing dry and stable trends lasting through next weekend. Lighter winds are forecast from Friday onward as another shallow cold front approaches the state from the northwest direction.

Hawaii’s Weather Details:  Satellite imagery continues to show a cold front on approach to the Hawaiian Islands, currently located northwest of Kauai. A band of low level clouds, in the warm sector ahead of the approaching front, is producing showers over Kauai. Weather conditions near Kauai will grow more unstable today, as strengthening southerly surface winds converge, carrying additional unstable moisture up from the south, and enhancing shower activity over the Garden Isle.

Radar imagery shows numerous showers moving into Kauai from the south, these showers will slowly intensify through the day. Cloud bands with scattered showers are also shown on local radar and satellite imagery moving into the east and southeast slopes of the Big Island.

The short range weather forecast trends towards the wet side for the western half of the state, as the prefrontal convergence cloud band near Kauai, and the approaching cold front combine forces over the western islands from tonight into Monday. This frontal system will weaken on approach, stalling and dissipating near Oahu by Monday. Expect a 24 to 36 hour period of wet weather through Monday over the western Hawaiian Islands.

Shower bands moving up from the south have potential to produce localized flooding in some areas, where they can line up and train over island mountains, with possible threats for Kauai and Oahu starting later this evening through Monday. The eastern most extent of thunderstorm coverage is limited to the western half of the state. By Monday afternoon, the main band of moisture should be centered around Oahu along the stalled out front. Enhanced shower activity will rapidly diminish from Monday night to Tuesday.

Molokai will see increasing shower trends from Monday afternoon through the Monday overnight hours, as the frontal band stalls near Oahu. Maui and Lanai will likely see less shower activity as the front will stall too far west of these islands for much enhanced rainfall. Big Island showers will favor east and southeast slopes in this pattern through Monday night, then back to typical easterly trade wind weather from Tuesday morning onward.

By Tuesday, easterly trade winds will sweep more stable conditions back into the islands, with periods of our typical windward and mountain showers, favoring the overnight to early morning hours. An upper level ridge will move over the state and strengthen Wednesday night into next weekend, limiting shower activity statewide. Another shallow cold front will approach the islands from the northwest direction from Friday into next weekend, weakening the surface ridge, and producing lighter southeast winds across the region.

Hawaii’s Marine Environment:  Moderate southeast flow will prevail across local waters, slowly veering more southerly tonight as a frontal system approaches from the northwest. Behind the front expect moderate northerly winds. Enough instability will exist along and ahead of the front to bring a slight chance of thunderstorms over waters surrounding Kauai and Oahu late tonight through Monday. However, the front is expected to dissipate near Oahu Monday night into Tuesday. Moderate easterly or southeasterly winds will be in place through at least mid-week.

Northwest swell will continue to slowly lower and maintain surf heights well below High Surf Advisory (HSA) Criteria. Deep low pressure presently situated just south-southeast of Russia’s Kamchatka Peninsula will deliver a large, long period northwest (310-320) swell early this week, with long period forerunners arriving by tonight. The distant source region of this swell compared to previous swell will focus energy in the longer period bands increasing confidence that surf will rise to well within the HSA range Monday and perhaps approach warning criteria for north and west facing shores as it peaks Monday night through Tuesday. A Small Craft Advisory for seas may become necessary for the northern waters during this time. The swell will then gradually subsides through mid- to late week.

Moderate southeast flow maintains small chop along east facing shores, while energy out of the southerly quadrant maintains small surf for south facing shores.

Interesting:  Antarctica’s Only Native Insect’s Unique Survival Mechanism

Antarctic midge 1st reported organism using both quiescence and obligate diapause in multiple overwintering.

Picture an Antarctic animal and most people think of penguins, but there is a flightless midge, the only known insect native to Antarctica, that somehow survives the extreme climate. How the Antarctic midge (Belgica antarctica) copes with freezing temperatures could hold clues for humans about subjects like cryopreservation, but there remain many mysteries about the tiny insect.

One mystery appears to have been solved by an Osaka Metropolitan University-led international research team. Graduate School of Science Professor Shin G. Goto and Dr. Mizuki Yoshida, a graduate student at the time of the research who is now a postdoc at Ohio State University, found that the midge deals with the seasons during its two-year life cycle by undergoing quiescence in its first year and obligate diapause in its second.

Quiescence is a form of dormancy in immediate response to adverse conditions, and when conditions improve, the organism becomes active again. Obligate diapause is a dormant period naturally induced at a fixed time in an organism’s life cycle, a rare form seen in insects in temperate regions.
