Area Forecast Discussion National Weather Service Honolulu HI 357 PM HST Tue Apr 23 2024

SYNOPSIS
Breezy to locally strong trade winds will continue through the week, with clouds and showers favoring windward and mauka areas.
Trades look to ease slightly this weekend as high pressure weakens to the north and low pressure develops to the far northwest.

DISCUSSION
Breezy to locally strong northeast to east trade winds will continue through the week as high pressure remains to the northeast. This will maintain a fairly typical trade wind pattern, with clouds and showers favoring windward and mauka areas.
Guidance continues to show a band of moisture moving across the state tonight which will bring another uptick in windward and makua showers, with some showers once again spilling over into leeward areas of the smaller islands. Shower coverage should trend down later this week as drier air slowly filters in. Trade winds will ease slightly over the weekend as high pressure weakens in response to a developing low far northwest of the state. Guidance continues to then show the potential for a front moving across the islands early next week.

AVIATION
Breezy to locally strong trade winds will prevail for the next few days as a surface ridge remains to the north of the islands.
Clouds and showers will continue favoring windward and mountain areas with occasional showers reaching leeward areas. Cloud bands with increased shower activity are expected to move in tonight into tomorrow. These showers will likely bring more widespread MVFR conditions to windward and mountain areas.

AIRMET Tango is in effect for moderate low level turbulence downwind of the terrain for all islands. AIRMET Sierra for mountain obscuration over windward areas is expected later this evening into tomorrow morning with the increased moisture.

MARINE
High pressure north of the state will slowly drift east driving strong trades over the next several days. The high is forecast to weaken around Sunday as a deep low develops northwest of the area. A Small Craft Advisory remains in effect for higher winds through Wednesday night covering all Hawaiian coastal waters.

Surf heights along all shores will remain below advisory thresholds through the weekend. A small, medium period northwest swell will arrive on 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.
