Detailed Forecast

Synopsis

Pleasant conditions are anticipated into early next week, with breezy easterly trade winds and temperatures running slightly above normal. The best chance for showers will be through the late night and early morning hours over windward and mauka locations, leaving most leeward locations dry. Trade winds will trend down Tuesday through midweek, and some moisture moving in from the southeast could boost rainfall chances for some locations.

Discussion

Guidance remains in good agreement and depicts the breezy easterly trades holding through Monday, then easing Tuesday through midweek as a front passes to the north. Plenty of dry air combined with rising upper heights will limit rainfall chances and keep the temperatures hovering slightly above average for this time of year. Any showers that do form will be brief and favor windward and mauka locations overnight through the early morning hours and over the Kona slopes through the afternoon periods.
As the trades weaken Tuesday through midweek, guidance shows a decent-sized area of enhanced low-level moisture moving in from the southeast. Lowering upper heights due to an approaching shortwave trough from the northwest along with this moisture support a slight increase in rainfall chances. A drying trend along with light to moderate trade winds returning is shown Thursday through Friday.

Aviation

Locally breezy easterly trade winds will continue across the island chain though the weekend. Although dry air aloft will limit showers and clouds, any showers that develop will favor the overnight through early morning hours and focus mainly along north through east-facing sections of the islands. Elsewhere, conditions will remain mostly dry. VFR flight conditions will prevail state-wide, with only isolated MVFR ceilings for brief periods within windward showers.
There are currently no AIRMETS in effect. However, low level mechanical turbulence downwind of the mountains of the islands may be possible later today, especially across the eastern half of the state.

Marine

A surface ridge will persist north of the state, maintaining moderate to locally breezy trades through the weekend. The Small Craft Advisory (SCA) for typically windier waters around Maui County and the Big Island has now been extended through Sunday afternoon as a result. The ridge will weaken as two fronts approach the area from the northwest beginning Sunday evening through the middle of next week. Thus, trades will ease below SCA thresholds Sunday night and beyond.
A long-period west-northwest swell continues to spread across the area with near seasonal average surf along most north and west facing shores. However, the swell appears to have already peaked locally. It will continue to gradually lower through early Sunday. The next northwest swell is expected by later Sunday, and peak near, or just above, the High Surf Advisory threshold along most north and west facing shores of the smaller islands Monday. This swell will then slowly subside through the middle of next week.
The current small, long-period south swell will slowly fade through the weekend. Typically small background south swells will return to south facing shores late in the weekend and into the first half of next week. Elsewhere, modest, choppy surf will persist along east facing shores through early next week.
