The anomalously deep closed upper low near 24N 151W this morning
is forecast to move east northeast away from the state through Tue
morning, bringing the core of coldest air aloft east of the state.
 Winds subside today as the pressure gradient relaxes.

A weak residual inverted trough remains over the area mid week,
with light synoptic winds and likelihood of daily sea and land
breezes developing diurnally as a result of the light flow.
Isolated showers are possible in conjunction with the sea and land
breezes mid week.

High pressure is forecast to build northwest of the islands Fri 10
May and then north of the islands Sat 11 May thru Sun 12 May.
Winds will gradually veer from north to northeast and east
northeast next weekend, with trades redeveloping.  A well defined
ridge aloft west of the islands builds across the islands next
weekend, keeping weather tranquil. Widely scattered showers are
expected to develop in upslope flow areas in the east northeast
winds next weekend into early next week.
