Detailed Forecast

Synopsis

Moderate to breezy easterly trade winds will persist through Thursday, then ease Friday into the weekend. Clouds and showers will favor windward the mauka areas, mainly through the overnight and early morning periods as pockets of moisture move through. A return of breezy trades is expected early next week.

Discussion

Early morning satellite and radar data showed a decent sized area of patchy low clouds and showers moving through our windward areas. Although most of this activity will continue to focus over windward and mountain locations, some showers will make it into our dry leeward spots of the smaller islands through the morning hours today (trade wind inversion floating around 8000-9000 ft). Drier air lurking upstream should arrive later today, which will translate to a return of a typical summer pattern (dry) for the islands.
Trades are forecast to ease Friday into the weekend as the ridge weakens to the north – potentially enough for localized land/sea breezes to form in sheltered locations. Showers will be sparse, mostly focusing over windward and mountain locations overnight through the mornings as pockets of low-level moisture move through. Breezy trades are forecast to return early next week as the ridge strengthens to the north.

Aviation

Moderate to locally breezy trade winds will continue through the TAF period, with showers concentrated mainly across windward sections and in channels between islands through tonight. Satellite data continues to show an area of lower/mid level clouds expanding in areal coverage across windward areas of the islands this morning, as a band of moisture from the east moves beneath a weak trade wind inversion. Current surface obs continue to show some MVRF cigs drifting across the islands this morning, associated with the cloud deck, however expect clouds to breakup some later this today as afternoon mixing develops. Overall, expect some MVFR cigs will continue across mainly windward areas, generating the continued potential need for AIRMET Sierra due to tempo mountain obscurations. Otherwise, expect mainly VFR conds across most TAF locations through tonight.

Marine

High pressure northeast of the state will keep moderate to fresh trade winds in place through Thursday. The trades will be locally strong over the typically windy waters around Maui and the Big Island at times, and a Small Craft Advisory is in effect for these areas through 6 PM today. The trades will ease a bit Friday through the weekend, then strengthen to fresh to strong levels early next week as a new high builds north of the island chain.
South shore surf will hold above the summertime average today, with a slow and gradual decline expected Thursday through Saturday. A series of new long-period south swells will elevated south shore surf above the summertime average again Sunday through the middle of next week.
North shore surf will remain flat through the next 7 days.
Steady trade wind swell will keep east shore surf below normal through the next 7 days. A small northeast swell will also move through the islands late Friday through early next week.

HFO Watches/Warnings/Advisories

Small Craft Advisory until 6 PM HST this evening for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
