The latest model guidance shows relatively good agreement from the
synoptic level over the region over the next week. Upper level
ridging is forecast to dominate the weather the next few days,
which may act to dampen the trade wind regime, favoring more
typical diurnal sea/land breezes with showers favoring the
windward areas. Going into this weekend and early next week,
ridging subsides and a weak trough may approach from the
southwest. Some deeper moisture and higher PWs may accompany this
feature, but still uncertainty between the GFS and ECMWF. High
pressure settling north of the Islands will help to assert the
trade wind regime to moderate levels, favoring the better
precipitation chances over the windward areas during the early
morning to overnight hours.
