High pressure to the north of the state through Monday will
maintain brisk to strong trades that will focus showers over
windward/mountain terrain. On Monday, the guidance shows energy to
the west/southwest of the islands consolidating into an upper low
which tracks over Hawaii Tuesday-Wednesday. There are plenty of
lingering uncertainties in the details, but models do show some
general agreement that precipitable water values and rainfall
should increase in association with this upper low. Meanwhile, the
surface high to the north will accelerate eastward in response to
a cold front and deepening trough moving in from the west. This
should bring moderately strong northerly winds spreading from west
to east following the frontal passage around Wednesday-Thursday
next week. More stable and drier conditions should follow next
Friday and the weekend as upper ridging moves in over the state
and high pressure becomes re-established to the northwest.
