The latest model guidance shows relatively good agreement from the
synoptic level over the region over the next week with the main
synoptic feature being an upper ridge persisting over the Islands
through the rest of this week. This combined with drier air will
help limit the scope of the shower activity, primarily favoring
the typical windward and mountain locations during the overnight
and early morning hours. The lighter trade winds will also support
more typical sea/land breeze interactions and shower activity.
Going into this weekend and next week, some indication that trade
wind regime should pick up to moderate levels, supporting the more
typical trade wind pattern. A passing shortwave south of the
region this weekend is likely to bring higher moisture for
enhanced precipitation in both coverage and intensity Saturday
through Monday. Beyond that, the upper low will move west of the
region with a drier airmass filtering back in, bringing back the
more typical trade wind flow and shower coverage.
