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.

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

It’s partly to mostly cloudy here in Maui County this morning. The low temperature at my place was 56 degrees.

839am, clear to partly cloudy, and nice beginning to this last day of the work week, of course in my case, I don’t have any last days of the work week…hahaha!

1220pm, it’s yet another super sunny early afternoon here on Maui, at least in most areas. This doesn’t mean that we’ll have lots of clouds later this afternoon into the evening…with even a few showers like we had last evening here in upper Kula.

420pm, I see a brush fire down in the Central Valley here on Maui.

6pm, it’s become mostly cloudy here in the upcountry area on leeward side of the Haleakala Crater…with a few sprinkles at the moment.

630pm, the clouds have cleared remarkably fast, and now at the end of the daylight hours, we’re being flooded with warm tropical sunshine.

Hawaii’s Broad Brush Weather Overview: High pressure far northeast of the state will lead to moderate to locally breezy trade winds. Expect to see fairly typical summertime weather as clouds and showers favor windward and mountain areas, with an increase in showers this weekend into early next week.

Hawaii’s Weather Details: A moderately strong high pressure syste remains nearly stationary far northeast of the state. Water vapor imagery shows a compact upper level low several hundred miles north of us, that is slowly drifting westward. Even with the upper low nearby, atmospheric soundings show a typical subsidence inversion just under 7,000 feet at Lihue and down to 5,000 feet at Hilo. Rainfall amounts across the state have been roughly a quarter to a half inch over the past 12 hours, with more of those reports across Kauai and Oahu.

The high northeast of the state will gradually shift northward over the next couple days, but we’ll remain in a pretty consistent trade wind flow. While the upper low is expected to stay north of the state, a trough rotating around it will help raise inversion heights this weekend. A pocket of moisture just outside the offshore waters, apparent as a showery band of cumulus on satellite imagery, will enhance rainfall chances this weekend. Trade winds speeds may lower a bit but still remain borderline breezy. While the trades will focus most rainfall across windward sections, there will be some brief showers reaching leeward areas as well.

Models show another pocket of moisture farther east tracking across the state early next week. The GFS is more aggressive bringing this moisture across the state Monday/Tuesday, with the ECMWF model fading out the signal more. Either way it should lead to an increase in windward showers early next week, with some rain reaching leeward as well.

Beyond Tuesday, we return to a more typical summertime trade wind pattern, with showers focused primarily at night and during the early morning. Wind speeds may also ramp back up a notch during next week, as the high northeast of us strengthens slightly.

Hawaii’s Marine Environment: High pressure far northeast will continue to drive moderate to locally strong trade winds. A Small Craft Advisory remains in effect for the typical windy waters around Maui County and Big Island. There will be a minor lull in trade speeds early Saturday, as the pressure gradient from the high northeast of the state relaxes a bit. While the high will pull away further to the north early next week, the gradient will remain tight enough across the nearshore waters to result in several more days of moderate to locally strong trades.

The recent small, long period south swell will continue its gradual decline. A reinforcing longer period south swell is scheduled to arrive Saturday. This little boost, combined with another small, long period south swell arriving Sunday night into Monday, will hold south shore surf to slightly under summertime averages. East-facing shore surf will remain rough, as moderate to fresh trades blow. A very small northwest swell may pass through early next week. This will keep north shore surf from going completely flat.
