Over the next couple days, generally weak winds at the surface
will allow for a sea and land breeze pattern to develop. Showers
are likely to develop where sea breezes form convergence over the
islands, as an overall moist airmass remains in place along with
troughing aloft and at the surface. Some localized heavy downpours
may be possible. Then by late week, the surface pattern looks
favorable for more typical easterly winds to form by later in the
week with a surface high to the north. The track and timing of a
weak cold front ahead of the high has come into somewhat better
agreement, with model guidance showing that the front may cross
into Kauai late Friday into Saturday before stalling and
weakening. This may locally enhance showers especially in windward
and mauka areas as a moist pattern remains. By early to mid-next
week, trade winds look to stay quite breezy to strong, with a
gradual trend down in the available moisture.
