A cold front currently near Kauai is forecast to move slowly
through early Wednesday, and then an anomalously deep trough aloft
and a high pressure center at the surface will push the front more
progressively southeast across the state late Wednesday into
Thursday. Moisture will continue to pool ahead of this front and
bring some enhanced rain chances for Oahu Wednesday afternoon,
Molokai/Maui Wednesday evening and night, and into the Big Island
early Thursday, as shown by the HREF. Behind the front, drier
dewpoints and slightly cooler temperatures are forecast while
northeasterly winds will be rather strong. Windy northeasterlies
may continue into Friday before winds gradually decrease in
magnitude into the weekend (though remaining breezy) while veering
a bit to a more easterly direction. Generally dry conditions are
likely for late week given the below normal moisture in place
behind the front. Moisture will gradually increase next week while
easterly trades continue as a surface high traverses north of
Hawaii, leading to windward/mauka showers.
