High pressure north of the state will support brisk weekend trades
and a windward/mountain focus for showers, but precipitable water
values are modest. Trades should weaken and trend more
southeasterly early next week as high pressure progresses eastward
and as a well defined cold front approaches from the west.
Guidance reasonably agrees that the front and amplified upper
troughing will reach the islands into midweek, accompanied by
moderate to heavy rainfall/thunderstorms. Precipitable water
pooling on the front may exceed 1.5". The front and enhanced
instability/moisture/precipitation should work through the islands
later next week, but expect lingering enhanced showers over the
unsettled eastern islands in closer proximity to the slow to
dislodge upper low/trough.
