One more day of light and variable winds is forecast across Hawaii
today, with daytime sea breezes dominating the flow and possibly
causing showers over interior areas where they set up, with
nighttime land breezes tending to clear out the clouds and rain.
Then surface high pressure will set up to the north of the state
Tuesday night into Wednesday, bringing a return to more typical
(moderate to eventually locally breezy) easterly trade winds that
should last through the weekend and into early next week, which
could bring rain showers to windward and mountain areas. Shower
activity could be enhanced particularly for the northern islands
(Kauai/Oahu) through Thursday, possibly Friday, as a band of
moisture associated with a dissipating cold front sets up. Then
there remains the possibility for increased moisture to reach the
Big Island around Friday-Saturday, and the GFS is the main model
showing this, but the enhanced moisture may stay south of land as
indicated by other guidance.
