Detailed Forecast
Synopsis
Moderate trades will focus showers over windward area, mainly at night. Afternoon sea breezes may increase cloud cover across leeward areas. Drier air and increasing stability will spawn fewer showers from mid-week onward.
Discussion
There is little to no change in forecast philosophy from last evening. A weakened ridge north of the main Hawaiian Islands remains sufficiently strong to drive light to moderate trade flow across local waters this morning. Areas of increased moisture keep clouds and showers focused over Kauai and windward portions of the Big Island, but windward areas of Oahu, Molokai and Maui have isolated to scattered showers as well. With little to no wind flow change anticipated in the short term, expect today's cloud and shower pattern to be similar to yesterday's pattern.
Drier air north and northeast of the islands, along with mid- level ridging, will move over the eastern end of the state today, then build westward over the next 48 hours. This will limit rainfall intensity for the remainder of the week and will inhibit shower activity from drifting leeward at night.
Aviation
Trade winds will remain light to locally moderate over the next few days. Local scale afternoon sea breezes will build clouds and a few showers over mountain and island interior sections. Clouds and showers in the overnight to early morning hours will favor windward airfields. Mostly VFR conditions will prevail with only brief MVFR conditions possible in showers.
No AIRMETs in effect.
Marine
A weak ridge north of the islands will keep light to moderate trade winds in place through Wednesday, with localized land and sea breezes near the leeward coasts. A return of moderate to fresh trades is expected Thursday through early next week.
A combination of small background southeast and south swells will keep some small, and well below normal, surf in place along south facing shores during the next 7 days. Only small surf is expected along north facing shores during the next 7 days, with perhaps a small boost from a north swell Thursday and Friday, and a north- northeast swell over the weekend. Surf along east facing shores will remain well below normal during the next 7 days.
