Guidance still overall suggests that moderate to locally breezy
mean trades will prevail into the weekend as high pressure bridges
from the north to northeast of the state. Meanwhile, slow moving
upper low/troughing over the state is acting to enhance
instability. This pattern favors locally enhanced showers over
windward and mountain areas, but with some spillage leeward.
Trades may weaken into a drier pattern from later weekend into
early-mid next week as ample closed upper trough development over
the mid-latitudes may drive a trailing front to the northwest of
the state. Overall, predictability and continuity overall seem
better than average for this forecast period with favorable
guidance trends consistent with increasingly blocky mid-latitude
flow.
