Following a pattern that favors enhanced showers and thunderstorms
today, models and ensembles indicate a drier pattern would return
as the associated mid-upper level trough and cold front depart. 
Trades should modestly redevelop mid week as a post-frontal high
pressure ridge builds just to the north of the state in a drier
air mass with more limited shower activities.  Thereafter, a cold
front should edge closer to Hawaii from Friday onward which should
weaken the trade winds once more as the surface high shifts
eastward into the subtropical northeast Pacific.  By the weekend,
a slight increase in shower activity is anticipated as a return
flow brings increasing moisture from the southeast behind the
departing subtropical surface anticyclone.
