Detailed Forecast
Synopsis
Breezy and showery trade wind conditions will continue through Thursday, with clouds and showers favoring windward and mauka locations. Trade winds may ease slightly this weekend as the ridge weakens to the north.
Discussion
Guidance remains in good agreement and depicts the wet trade wind pattern persisting through Thursday as bands of low-level moisture move through. The initial band that has moved in overnight has led to an increase in windward shower coverage, with some spilling over into leeward sections of the smaller islands. Observations at the gauges reflect this uptick in showers with accumulations reaching a quarter to three quarters of an inch with localized higher amounts above two inches over the past six hours. Expect this showery trend to persist through midweek, with the next band approaching from the northeast. The shower coverage should trend down by Friday as this second band moves out and some drier air moves in.
The breezy easterly trades may ease slightly next weekend as the ridge weakens to the north in response to deep low pressure developing far northwest of the state near Midway.
Aviation
Bands of clouds will bring a MVFR cigs/vsbys and SHRA over windward and mauka areas this morning. A few SHRA will make it to leeward sides with lowering cigs/vsbys as well.
AIRMET Sierra is in effect for mtn obsc for all islands.
AIRMET Tango is also in effect for moderate turb below 080 for S and W of all islands.
Marine
High pressure north of the state will slowly drift east and strengthen over the next few days, resulting in fresh to strong trade winds over the islands. A Small Craft Advisory remains in effect for higher winds through Wednesday covering most Hawaiian coastal waters from Oahu to Big Island.
Surf heights along all shores will remain below advisory thresholds through the weekend. A small, medium period northwest swell will arrive late Wednesday and continue through Saturday. Choppy, rough surf expected all week along east facing shores due to the trade winds. South facing shores will continue to see small background swell pulses through rest of the the week.
HFO Watches/Warnings/Advisories
Small Craft Advisory until 6 PM HST Wednesday for Oahu Leeward Waters, Kaiwi Channel, Maui County Windward Waters, Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
