Detailed Forecast

Synopsis

Locally breezy and dry trade wind weather will continue today. Showers will be focused along windward slopes, and aside from a few afternoon showers on the South Kona slopes, leeward areas will remain dry. Trade winds will trend down tonight through midweek, and some moisture moving in from the southeast could boost rainfall chances for some locations. A dry trade wind pattern will return Thursday through Saturday.

Discussion

Guidance remains in good agreement and depicts the breezy easterly trades holding today, then easing tonight through midweek as a front passes to the north. A diffuse area of moisture will move up from the southeast Tuesday and Wednesday and cause an uptick in shower activity, mainly along southeast slopes of the Big Island and Maui. If the trades drop enough for leeward sea breezes to develop, all islands may have a chance of afternoon showers over leeward terrain on Wednesday. Though weaker, the ridge aloft will remain in place and likely keep any rainfall at moderate intensity.
A return to somewhat dry trade wind weather is due on Thursday as the enhanced moisture clears the islands. The GFS and ECMWF are showing a weak upper level trough moving in from the northwest. This feature could produce an increase in high clouds, but no other impacts to local weather are expected at this time.

Aviation

Fair weather conditions will continue today with a high pressure ridge north of the islands producing moderate to locally breezy trade winds. Isolated showers are possible mainly over windward and mountain areas.
Currently there are no AIRMETs in effect and none are expected.

Marine

A new northwest swell will continue to build this morning and peak during the day today, then lower gradually Tuesday through Wednesday. Latest buoy observations show a peak of 10 ft 14 seconds at buoy 51001. A High Surf Advisory is in effect for north and west facing shores of Kauai, Oahu and Molokai and north facing shores of Maui through tonight. A smaller and shorter period northwest swell is expected during the Wednesday night through Thursday night time period, followed by another small to moderate northwest swell towards the end of the week.
South facing shores will continue to experience small, mainly background south swells throughout the week. Short period choppy surf will remain on the small side through the week as trade winds remain on the lighter side over and upwind of the state.
High pressure north of the state will produce moderate to locally strong trade winds across the area today. As this high shifts east, winds will gradually decrease through the middle of the week. A Small Craft Advisory (SCA) is currently posted for the typically windier waters around Maui County and the Big Island through this afternoon. The above mentioned advisory level northwest swell will likely cause seas to exceed the 10 foot SCA threshold over exposed waters through Tuesday. Otherwise, winds and seas are expected to remain below SCA levels through Friday.
