SYNOPSIS
Breezy trades will briefly weaken over the weekend, before increasing again early next week. Mostly dry conditions will prevail, with clouds and brief showers favoring windward and mauka locations, mainly during the overnight through early morning hours, as areas of moisture move through periodically.
DISCUSSION
No changes to the forecast this morning. However, the Big Island summit winds are near Wind Advisory criteria, so keeping a close eye on that. Winds will hover near the advisory levels through Saturday before trending downward.
High pressure far to the north-northwest of the state will drift to the east, with an associated ridge remaining north of the region. This will maintain a general trade wind pattern into the middle to end of next week. The breezy trades will hold today, then ease into the light to moderate range over the weekend as the ridge to the north weakens due to a low passing far to the north. The southern extent of a mid- to upper-level trough associated with this low will pass near the islands to the north today and into the weekend, which could support a slight increase in windward shower coverage during the overnight/early mornings.
Rising upper heights along with a strengthening surface high to the north will support relatively dry conditions with breezy easterly trades through the majority of next week. Expect clouds and limited showers to ride in on the trade wind flow from time to time, remaining focused over the typical windward sides of the islands and concentrated during the overnight and morning hours.
Clouds and limited showers are also expected over the west slopes of the Big Island each day, mainly during the afternoon and evening hours.
AVIATION
Moderate trade winds will remain in place today and gradually weaken this evening through the weekend. A band of low clouds and SHRA will continue bringing MVFR conds to the windward and mauka locations of the islands.
AIRMET Sierra for mtn obsc remains in effect for Kauai, Oahu, Molokai, and Maui. This may need cancelled this afternoon as conds improve.
MARINE
A low pressure system passing far to the north of the state will weaken the subtropical ridge of high pressure. This will result in a slight weakening of the trade winds across the coastal and offshore waters. A Small Craft Advisory in effect for the usually windier zones around Maui County and the Big Island is on track to be dropped by 6 PM HST today. The ridge of high pressure should rebuild early next week, which should produce fresh to locally strong trades once again.
Along the south-facing shores, moderate surf will decline slowly into the weekend. For the north-facing shores, a small, short- period north swell should continue into Saturday. A moderate, medium-period north swell is expected to arrive on Saturday night. Surf along east-facing shores will remain small through the weekend and may increase slightly early next week as the trades strengthen.
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.
