.Short term...
TONIGHT THROUGH FRIDAY NIGHT...High pressure to the south will
continue to hold stable weather and breezy trades through Friday
night. RAOB from this afternoon depicts a dry profile with an
inversion near 850 mb. As the high pressure slowly migrates
eastward, breezy trades will persist across the islands. Satellite

remain north through the weekend.

.Long term...
SATURDAY THROUGH WEDNESDAY...Breezy trades are expected to
diminish to gentle flow and shift east on Saturday night as the
high pressure moves farther southeast. Stable weather continues
through the weekend. The trough up north will again move south on
Wednesday. This will increase sky coverage. Another high pressure
approaching the southwest will shift east winds to the southeast
on Sunday night. As the high pressure moves near south of the
islands, winds will increase to breezy flow on Monday night and
later increase to strong trades on Tuesday and Wednesday. Expect
another strong tradewind event starting Monday night.

Another strong high pressure to the far southwest will increase
and shift winds to breezy trades on Monday night. This will build
