The latest global numerical guidance indicates that the flow
across Hawai'i will switch from dominant polar westerlies to
tropical easterlies within the next week. The energetic trough
sharpening to the east of the islands this weekend will turn the
surface winds to the north--bringing an abrupt end to the focused,
baroclinically-driven showers currently in progress. By late next
Thursday night, the first return-flow/tropical moisture should
begin to lift across the Big Island, with the entire state in the
thick of the humid air by Saturday. Once the northerly flow takes
over, preciously few showers are anticipated--likely into the
middle of next week even once warm advection begins. Next Saturday
looks showery statewide--particularly across the Big Island and
Maui.
