Synopsis for hawaiian coastal waters - High pressure northeast of the state will help drive strong to near gale force trades through tonight. The high is forecast shift east Friday through the weekend while an area of low pressure develops far northwest of the state. This will allow winds to gradually ease this weekend, then hold into early next week.

Area Forecast Discussion National Weather Service Honolulu HI 357 PM HST Thu Apr 25 2024

SYNOPSIS
Strong trade winds will gradual decrease and veer toward the east-southeast through early next week. Several plumes of moisture will produce passing showers across windward and mountain areas through Saturday. A drier weather pattern is expected Sunday into early next week with light to moderate easterly trade winds. Trade winds should be light enough for sea breezes to develop during the day.

DISCUSSION
A 1031mb high far north of the state is currently producing strong trade winds across the state this afternoon. Latest satellite and radar imagery shows mostly dry conditions across the state with some scattered showers over windward areas and the Kona slopes of the Big Island. Looking upstream of the state, there is a plume of moisture upstream of Maui, which will likely bring an increase of scattered showers tonight across windward areas. Another plume of moisture looks to arrive sometime late Friday into Saturday.
Overall an increase of showers is expected through Saturday, primarily over windward areas. Rainfall amounts should remain light to moderate, due to stable conditions aloft.

A developing trough northwest of the state over the next few days will cause the winds to veer toward the east-southeast on Saturday, which should decrease the winds across leeward areas of the smaller islands due to shadowing from the Big Island. A hybrid wind pattern is expected over the weekend over leeward areas of the smaller islands with a mix of easterly trade winds and sea breezes. Meanwhile for the windward areas, moderate to locally breezy trade winds are expected this weekend. As the trough moves closer to the state early next week, winds will weaken further and sea breezes will develop across more areas. Sea breezes during the day time should lead to afternoon clouds each afternoon over interior and leeward areas. Due to precipitable water values being near normal or just below normal, no significant precipitation is expected with the afternoon showers but some light rain will be possible.



AVIATION
Breezy to locally windy trade winds will continue through Friday.
Clouds and showers will favor windward and mauka areas, with isolated showers occasionally spilling over to leeward areas...bringing periodic MVFR conditions. Cloud cover and shower activity will be greatest overnight into the morning hours.
Otherwise, VFR conditions will generally prevail.

AIRMET Tango is in effect for moderate low-level turb downwind of the terrain for all islands. These conditions are expected to improve sometime tonight heading into Friday.

MARINE
A 1031 mb surface high, centered around 900 nm northeast of the state, will slowly drift eastward over the next several days. This feature will continue to help drive strong to locally near gale east northeasterly trade winds across the islands this afternoon through tonight. Friday into the weekend, low pressure is forecast to develop well northwest of Hawaii. In response, easterly winds will gradually weaken to light to moderate and shift slightly out of the east southeast. A Small Craft Advisory (SCA) continues for all Hawaiian coastal waters through Friday morning and has been extended for windward Oahu waters and eastward through Friday afternoon. The advisory may need to be extend into Saturday for some of the more typical windier locations around the Big Island and Maui County.

Surf heights will remain below advisory thresholds for all shores through the forecast period. Hanalei buoy (51208) shows a medium period northwest swell continuing to fill in. Expect surf to rise locally through the evening and peak tonight. Another small, medium period northwest pulse will enter the waters Friday night, peak Saturday, and subside Sunday. Expect these swells to produce small surf along north and northwest facing shores. Persistent trades will continue to produce choppy, rough surf through Friday along east facing beaches. By this weekend, weakening trades will allow this surf to lower and hold into early next week. Small background southerly swell, observed this afternoon at Barbers Point Buoy (51212) as 2 feet 14 seconds, will lead to small surf along south facing beaches through the forecast period.
