Detailed Forecast

Synopsis

Breezy easterly trade winds will continue through early next week, with clouds and showers favoring windward and mauka areas.

Discussion

Guidance remains in good agreement and depicts a return of a more typical trade wind pattern today, which will persist into next week as strong high pressure remains anchored to the north. Pockets of low-level moisture moving through from east to west will enhance shower coverage periodically over windward areas, mostly overnight through the morning periods. Rainfall accumulations will be minimal through the period, with little to no rain expected over most leeward areas.

Aviation

A vast field of broken to overcast stable low clouds extends east from the islands and will likely create MVFR ceilings across windward shores and slopes through today. Windward TAF sites may see MVFR ceilings from time to time. Our airmass is rather stable, so showers will not be heavy enough to impact visibilities significantly. Blustery trade winds will continue for the next day or so.
AIRMET Tango remains in effect for tempo moderate turbulence below 9000 feet over and immediately south through west of mountains on all islands. AIRMET Sierra remains in effect for tempo mountain obscuration for Maui, Molokai, Oahu, and Kauai, and the Big Island.

Marine

A high pressure system building in the Central Pacific basin over the next few days will keep fresh to strong trade winds blowing across the region through next week Wednesday. The Small Craft Advisory has decreased in coverage this morning, back to the windier waters around Maui and the Big Island.
No significant swells are expected over the next seven days with only small surf heights forecast into early next week. Surf along east facing shores will remain small and choppy, driven by trade wind wave energy. A small long period south-southwest (200 degree) background swell will move into the islands from Sunday through Tuesday with only a small increase in the surf heights along south facing shores.

HFO Watches/Warnings/Advisories
