Area Forecast Discussion National Weather Service Honolulu HI 958 PM HST Wed Jul 28 2021

UPDATE. Tsunami Watch for the State of Hawaii has been cancelled.

SYNOPSIS. Moderate to breezy easterly trade winds will strengthen late Thursday through the weekend. Clouds and showers will favor windward and mauka locations, with the best chances through the overnight and early morning periods. A return of drier trade wind conditions is anticipated Friday through the weekend.

DISCUSSION. The upper trough that led to cloudy conditions over the western end of the state today is lifting northward and away from the area. Plenty of middle- to upper-level dry air following it has cleared some of the high clouds out this evening over Kauai and Oahu. Expect this trend to continue into the second half of the week with stable trade wind conditions returning. There is a large area of moisture moving into the eastern end of the state this evening that will support decent windward and mauka shower coverage overnight through the morning hours Thursday. In its wake, satellite data reflects dry air farther upstream of the Big Island. Guidance has initialized well with this and has the dry air moving through from east to west late Thursday through Friday. This dry air combined with rising upper heights will lead to more of a suppressed and stable environment this weekend, which will limit cloud/shower windward coverage. Similar conditions will carry into next week.

AVIATION. VFR conditions are expected to prevail across the main hawaiian islands overnight. The upper level disturbance that brought in some mid and high clouds and isolated thunderstorms to the waters around Kauai this morning is now history. The remnants of a disturbance that was expected to affect eastern Big Island tonight, will miss the island. So all we have is the widely dispersed low clouds embedded in the moderate to locally strong trade wind flow that is expected to continue through Thursday. So for AIRMET Tango for low level turb is likely to continue despite the lack of evidence on the radar derived winds. Low clouds embedded in this trade wind flow will bring some brief passing MVFR conditions as they impact the windward and mountain areas. A shower or two is possible along the Kona coast as well overnight. Tops of these showers will be around 8k feet. No other AIRMETS are anticipated overnight.

MARINE. A 1025 mb high is centered far north of the state. This places the area in a fresh to locally strong trade wind environment. A Small Craft Advisory (SCA) is currently posted for the typically windy waters around Maui County and the Big Island. The high is forecast to gradually strengthen later in the week and over the weekend with an uptick in trade winds expected. The SCA may need to be expanded in coverage when this occurs.

Surf along east facing shores will remain small through Friday, then trend up over the weekend in response to strengthening trades locally and upstream of the state over the eastern Pacific.

Southerly swell activity will remain rather low for this time of the year with just background swells expected from the south and southeast. There is also a slight chance for a small westerly pulse from tropical cyclone activity in the far west Pacific which could provide for some small surf along exposed shorelines.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM HST Thursday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
