An unsettled pattern will continue through Tuesday. A surface 
trough and band of enhanced moisture will persist over the state 
while an upper low tracking just northeast of the main islands may
provide enough instability to support some thunder in locally
heavy showers that should have a land/sea breeze focus due to
light prevailing winds. Guidance consensus maintains the idea of
the pattern returning to a trade regime Wednesday onward as the
upper low contiues eastward and opens. Windward/mountain-focused
showers should trend lighter as precipitable water values settle 
to near or slightly below climatological levels. One surface high 
passing by to the north around Friday and another next Tuesday 
will likely support brisk winds from Friday onward.
