Area Forecast Discussion National Weather Service Honolulu HI 343 AM HST Mon Apr 15 2024

SYNOPSIS
The wet pattern will continue over the eastern end of the state today as a cold front around Maui County continues eastward.
Meanwhile, light to moderate west-northwest winds with drier air filling in from west to east will continue in the wake of the front as high pressure builds north of the state. Expect a more typical trade wind pattern to return with showers favoring windward and mauka locations Wednesday through the second half of the week.

DISCUSSION
The short-term guidance remains in good agreement and depicts the wet pattern persisting today over the eastern end of the state due to an upper trough to the north and its attendant surface front slowly advancing down the island chain. Radar imagery showed the back edge of the moderate showers with decent rainfall rates along/ahead of the front around Maui early this morning beginning to weaken. The latest rainfall summary depicted 24-Hr rainfall totals (through 2 AM HST) ranging from 3 to 5 inches on Kauai to 1 to 2 inches over Oahu and Maui County. In addition to the wet conditions, expect a wintry mix over the Big Island summits this morning with warning level westerly winds. Elsewhere, light to moderate west-northwest winds and drier conditions have begun to fill in from west to east. Dewpoints are forecasted to dip into the upper 50s to low 60s this afternoon, which will limit rainfall chances. The drying trend will continue over the eastern end of the state on Tuesday as high pressure builds to the north and the fronts slips east of the area. A return of a more typical trade wind pattern with clouds/showers favoring windward areas is anticipated Wednesday through the second half of the week.

AVIATION
A quick-moving cold front will exit Hawaii to the northeast today.
Clearing has already begun on Kauai. Frequent rain showers possibly mixed with isolated thunderstorms will persist across the central Islands this morning then taper off from the west in the afternoon. The front is weakening as it presses eastward, so the heaviest showers are not expected to reach the Big Island.

Meanwhile, east-southeast flow in advance of the front will carry repeated bands of light showers towards the Big Island with the greatest impact being felt along the windward coast south of Laupahoehoe tonight.

AIRMET Sierra for mountain obscuration is currently in effect for Maui and Molokai. Conditions are expected to improve in the early afternoon.

Moderate upper level turbulence could redevelop across the state later today as the upper level trough to the northwest of Hawaii digs southward.

Occasional light rime icing is expected in layered clouds above 15 kft. Conditions are expected to persist into the evening hours.

MARINE
A front over Maui County will continue to push slowly eastward today and tonight, then stall out and slowly dissipate near the Big Island Tuesday and Wednesday. Light to moderate west to northwest winds will fill in behind the front today, with winds becoming rather light for Tuesday. Moderate north to northeast winds will fill in by late Wednesday, with fresh to strong trades expected Thursday and Friday as high pressure builds eastward well to the north of the state. The trades appear to ease a bit over the weekend as the high to the north weakens.

A Small Craft Advisory remains posted for the Alenuihaha Channel and leeward Big Island waters today due to funneling effects between Maui and the Big island. A SCA has also been issued for 10 foot seas around Kauai today.

Surf along north and west facing shores will trend up today as a northwest swell builds. Surf may flirt with low end advisory levels along north facing shores of the smaller islands late today and tonight, but should hold just below the advisory threshold of 15 feet. Surf along east facing shores will remain very small through the week. Small, medium to long period south swells will keep some small surf rolling into south facing shores through the week.

HFO WATCHES/WARNINGS/ADVISORIES
Wind Advisory until 6 PM HST Monday for Haleakala Summit.

High Wind Warning until 6 PM HST Monday for Big Island Summits.

Winter Weather Advisory until 6 AM HST Monday for Big Island Summits.
