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. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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 Aloha Friday comments:  I’m at my friend Linda’s here in Corte Madera, Marin County, CA on a working vacation.

402am HST, it’s mostly clear with thin high clouds here in Corte Madera, CA, the low temperature was 42.5 degrees…with calm winds

 

Hawaii’s Weather Highlights…as of Friday morning:  Today will be a transitory day from a more wet to an overall drier pattern across the island chain. Trades will be the dominant wind as scattered showers focus along windward and upslope mauka areas. Trade weather will continue this weekend, with a front passing across the state from the north early next week. Relatively cooler and drier weather is expected in the front`s wake early next week.

Weather Narrative…as of Friday morning: Energy within the southwest steering flow…ahead of a near stationary mid to upper level weakening low southwest of the state…has been passing across Hawaii overnight. Evidence of this was the blow up of thunderstorms over eastern Big Island`s coastal Puna District and surrounding waters. We are still under a very moist air mass of between 2.1 to 2.6 inch precipitable waters that fall in the maximum climatological categories for late October standards.

Weak mid level ridging will be over the state today as the aforementioned low slowly slides off stage left. The synoptic movement of these primary players should limit any mid to upper level forcing over the islands, as the energy east of low should remain well west of the state. The surface trough that has been over us the last few days has become diffuse enough to be unmentionable and verifies that the state is under a light to moderate trade flow pattern.

This moisture-rich resident air mass is going nowhere soon, so expect more clouds than sun and scattered windward-focused showers through the day. Halloween`s forecast calls for a typical October day by Hawaiian standards, albeit a touch more humid than many would like. Trades will weaken a bit and this will keep conditions more muggy through the partly (leeward) to mostly cloudy (windward) day. Evening conditions should be more treat than trick with calm to very light trade breezes under partially cloudy skies. The highest rain chances will be over the windward exposures of all islands, especially eastern Big Island. Any passing shower will be infrequent and a quick hitter.

A central North Pacific trough will swing down and pass east of the state Sunday. This will likely push a weak front across the island chain late that night into early Monday. Strong high pressure building behind this weak boundary will produce strengthened northerly winds from late Sunday through the middle of next week. Possible sweater weather as cooler and drier air moves in from the north early next week. Post-frontal dew points lowering into the lower 60’s Monday with a stout north-northeast breeze will be a noticeable more autumn-like change, from these recent wet and more humid conditions.

Look for a typical trade-like precipitation pattern as infrequent showers affect windward communities and upslope mauka regions. Next week will be one of generally quiet trade weather. During the end of next week, an area of disturbed weather far southeast of the islands will be monitored for the potential development of a tropical cyclone.

Fire Weather: Recent rain and light winds have kept fire weather concerns low. As the soil and vegetation begins to dry out the next couple of days, fire weather conditions will move into the more moderate category. The passage of a weak front early next week will introduce breezy north northeast winds in its wake. Drier conditions are expected after this boundary`s late Sunday or early Monday passage. Thus, fire weather concerns will continue to be on the rise through next week.

Marine Conditions…as of Friday morning: A weak trough near the eastern end of the state that has been a focus for showers and thunderstorms over the past few days, will slowly move southward and dissipate today. Therefore, expect shower and thunderstorm coverage to gradually reduce over the next 24 hours. Ridging to the north will gradually drive moderate to fresh easterly winds over most waters today into the weekend. A Small Craft Advisory will likely be needed late this weekend into early next week due to a combination of increasing trade winds and high seas as a result of an incoming north-northwest swell.

A small, short period north-northeast swell will fill in today and maintain small surf along north-facing shores. A larger, long- period northwest swell will begin to arrive late Saturday. This swell will likely push north and exposed west shore surf above the High Surf Advisory threshold Sunday into Monday. The swell will shift slightly more northerly and may briefly build further on Monday before dropping Tuesday. Depending on the exact direction, a Marine Weather Statement may eventually need to be issued to due the potential for harbor surges at Kahului and Hilo.

A small, medium period south swell will peak today, though surf along south-facing shores will remain below High Surf Advisory levels. This swell will then gradually decline through the weekend. During the first half of next week, south shore surf will return to below seasonal averages.

Surf along most east-facing shores will rise slightly today due to wrap from the north and southerly swells. Additionally, east- facing shorelines exposed to the larger north swell Sunday night into Monday will have the potential for advisory level surf during that time.

Interesting:  Powering Solar-Powered Flight

Study reveals battery performance targets for solar stratospheric aircraft.

A sleek, pilotless, solar-powered airplane that soars through the atmosphere to monitor climate or track wildfires was once just an idea.

Now, these high-altitude specialty aircraft are advancing from early prototyping demonstrations towards potential commercial applications, supported by decades of research and development involving Harvard scientists, aerospace engineers, and industry collaborators.

In a new paper published in ACS Energy Letters, researchers in the John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with partners in industry and the University of Michigan, lay out a pathway to clearing the most significant hurdle still facing extended solar flight: battery performance.
