Detailed Forecast

Synopsis

Breezy easterly trade winds will continue through Friday, with clouds and showers favoring windward and mauka locations overnight through the morning periods. Trades will become strong and gusty over the weekend as high pressure builds north of the state. Increasing moisture and diminishing trade winds could lead to better shower coverage early next week as an upper disturbance moves into the area.

Discussion

Water vapor imagery showed the upper trough that led to a few storms over the eastern end of the state yesterday afternoon shifting eastward and away from the area early this morning. Rising upper heights and drier conditions will result in a more stable pattern statewide through the weekend. Showers will favor the typical windward and mountain locations overnight through the morning periods as pockets of moisture move through, leaving leeward areas mostly dry. Easterly trades will be breezy through Friday, then strong over the weekend as 1034 mb high pressure sets up north of the state. These strong winds may result in the Wind Advisory threshold being reached/exceeded Saturday (peak of the event) for the windier locations in Maui County and on the Big Island.
Trade winds will ease early next week as the ridge weakens in response to a cold front passing far to the north. Another upper level trough moving into the area could tap into some moisture lurking to the south. If this materializes, expect increasing rainfall chances where the moisture becomes focused.

Aviation

Showers remain scattered across the state this morning, mainly focused along windward areas and in between islands in convergent moist trade wind flow. Easterly trade winds will continue to strengthen and become breezy across the state through tonight as high pressure anchors in north of the islands. This trade wind pattern will focus showers and clouds along north through east windward slopes, while afternoon sea breeze clouds and showers are possible over sheltered leeward areas of the Big Island once again this afternoon. Mostly VFR conditions are expected through the TAF period, with brief periods of MVFR cigs and potential MVFR vsby possible in passing showers.
No AIRMETs are currently in effect. However, MVFR cigs and potential MVFR vsby in locally hvy showers will occasionally generate a period of tempo mountain obscuration through tonight.

Marine

Trade winds will become fresh to strong today as strong high pressure builds north of the area. A Small Craft Advisory is now in effect for the typical windy zones around Maui County and the Big Island. Winds will peak near gale force around Maui County and the Big Island this weekend as the high moves eastward and stalls north of the state. Seas will respond and become rough, with the likely expansion of the SCA to all coastal waters for winds and/or seas this weekend.
Surf along north and west facing shores will slowly trend down into tonight as a north northwest swell declines. A new long- period, northwest swell associated with a large batch of gales far northwest of the islands will begin to build down the island chain early Friday morning. This swell is expected to peak Friday night into Saturday, with surf heights likely reaching advisory levels for exposed north and west facing shores, before easing into early next week.
Surf along east facing shores will trend up late today and become rough Friday through the weekend as the trades increase. Surf along south facing shores will remain small through the weekend with mainly background pulses.
