...Wet Weather Pattern...

Models and ensembles still generally agree in showing the
settling of an upper trough/closed low and an organized surface
system just to the west of the state through Friday. Weakening and
veering lead flow to southeasterly to southerly winds over the
state will bring in deepened moisture to fuel showers with heavier
local downpours. A flood watch remains in effect for the western
islands today. The upper system should slowly eject and lose
influence into the weekend, but as a moisture pooling trailing
front and deep shower focus is expected to work slowly into the
state from the west, with an associated weather focus lingering
into next week.
