A land and sea breeze pattern will be in place over Hawaii for the
next few days, as trades diminish as a result of a weak pressure
gradient due to a surface low well north of the state pushing a
front across the Pacific and hovering north near the islands.
Clouds and any showers that form will favor that land/sea breeze
pattern through Tuesday and Wednesday. The front looks to stall
and dissipate just north of Hawaii around Wednesday
night/Thursday, with the band of moisture ahead of it perhaps
making it into the northwestern islands, but any enhanced rain
looks to stay north. By later in the week, a surface high is
forecast to form northwest of the state and extend its ridge
toward Hawaii, with its pressure gradient sufficient to reform
easterly trades. A hybrid trade/sea breeze pattern looks possible
on Thursday before a more typical trade wind pattern forms on
Friday and should persist through the weekend into early next
week, with any showers focused on windward/mauka areas.
