Detailed Forecast

Synopsis

Dry and breezy trade wind conditions are expected through the weekend and into early next week. The best chance for showers will be through the overnight and early morning periods over windward and mauka locations.

Discussion

Guidance remains in good agreement and depicts the subtropical ridge strengthening to the north over the weekend. This combined with rising upper heights and drier air moving in will support more of a suppressed and stable environment. Any showers that do development will favor windward and mauka areas, leaving little hope for reaching our parched leeward areas where drought conditions continue. The exception will be over the Kona slopes of the Big Island, where isolated afternoon showers are possible each day. Similar conditions will carry into next week.

Aviation

High pressure north of the islands will allow for moderate to breezy trades to persist trough the remainder of this morning and into the afternoon. Isolated to scattered showers will mainly affect windward coasts and slopes and bring brief periods of MVFR ceilings and visibility. Isolated showers elsewhere.
AIRMET TANGO remains in effect below 8000 ft over and immediately south thru west of mountains for tempo moderate turbulence.
AIRMET SIERRA has been issued for north thru east sections of the Big Island above 2000 feet due mountain obscuration from low clouds and showers.

Marine

High pressure far northeast of the state will slowly drift eastward and build into the weekend. Trade winds will gradually strengthen through the weekend. Widespread strong trades are expected over most Hawaiian waters by Sunday. The Small Craft Advisory (SCA) was expanded this morning to include most eastern Hawaiian waters and channels. This SCA will likely be expanded in coverage this weekend due to increasing trade winds.
Surf along east facing shores will remain small today, then trend up through the weekend in response to strengthening trades locally and upstream of the Hawaiian Islands.
Southerly swell activity will remain rather low for this time of the year with just background swells expected from the south and southeast. Nearly flat conditions will continue for north and west facing shores into early next week.
