Area Forecast Discussion National Weather Service Honolulu HI 342 PM HST Thu Mar 4 2021
SYNOPSIS. Breezy trade winds will continue for the next couple of days as high pressures lies far to our north. Winds will increase over the weekend and on into early next week as the high to our north strengthens. An upper trough will linger over the area throughout the forecast period. This will cause for a rather wet trade wind pattern setting up. Clouds and passing showers will favor windward and mauka areas with the trade winds sufficiently strong enough to blow some passing showers over to leeward areas at times.
DISCUSSION. Strong high pressure is centered far to the north northeast of the state resulting in breezy trade winds across the area. Moisture embedded in the trades is providing for some passing showers over windward and mauka areas with a few light passing showers being blown over to leeward areas at times of the smaller islands. Daytime heating has also allowed for a few showers to form over the Kona slopes. These showers will likely taper off this evening.
The high is forecast to drift east southeast and weaken slightly through Friday night. Also a weak low level trough will develop along an old frontal boundary. This will allow for a slight downward trend in trade wind speeds. Meanwhile, an upper trough will sharpen up over the area. This will keep the airmass a bit less stable which will allow for a wetter trade wind shower regime to set up especially for windward and mauka areas. Winds will be sufficiently strong enough to blow some passing showers over to select leeward areas at times. The upper trough may also allow for the thickening up of high clouds over the area from time to time.
By Saturday, a surface high will strengthen north of the state with trade winds speeds increasing once again to breezy and windy levels. The upper trough will continue to linger over the area resulting in the wet trade wind pattern continuing through at least Sunday.
This wet trade wind weather pattern will continue on into the middle of next week as the trough aloft remains near the area and abundant low level moisture moves into the islands from the east. Trade winds will remain elevated as strong high pressure remains to our north. Future shifts may need to consider adding a slight chance of thunderstorms to the forecast for early next week mainly for the Big Island.
AVIATION. With high pressure far northwest of the islands, moderate to locally breezy northeast trade winds will persist over the next day or two. Lower ceilings and showers, with accompanying MVFR conditions, will mainly affect windward and mauka sections. A surface trough is expected to continue developing near the state through tonight. The trough will likely increase showers over the smaller isles through Friday, with Kauai seeing the initial wave of showery low clouds this afternoon. And high cloudiness will be streaking over the area from the west.
An AIRMET for mountain obscuration has been issued for Kauai because of increasing low cloudiness and showers. Other islands will likely be included in subsequent issuances as showers increase over more of the state.
MARINE. A Small Craft Advisory (SCA) includes waters around Kauai, the Kauai Channel and windward Oahu waters for combined seas near 10 feet. SCA conditions will spread to most waters Friday and continue over the weekend due to building seas and winds as the high to our north strengthens.
The current northwest swell will give way to a reinforcing north swell Friday that will bring surf heights near high surf advisory levels Friday afternoon and Saturday before slowly diminishing Sunday. A bump in east shoreline surf will occur over the weekend as the trade wind swell increases. Background south swells will provide small surf to south facing shores.
HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory from 6 AM Friday to 6 PM HST Saturday for Kaiwi Channel-Maui County Windward Waters-Maalaea Bay-Pailolo Channel-Alenuihaha Channel-Big Island Windward Waters-Big Island Leeward Waters-Big Island Southeast Waters.
Small Craft Advisory until 6 PM HST Saturday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters-Kauai Channel- Oahu Windward Waters.
