Another day of a land/sea breeze pattern is likely on Thursday for
most of Hawaii, as a frontal boundary analyzed just north of the
state disrupts the typical pressure gradient that leads to trades.
Moisture convergence associated with this front could lead to
enhanced clouds and showers for Kauai Thursday as the front stalls
and dissipates. By Friday, the surface high forming northwest of
the state will extend its ridge toward Hawaii, with its pressure
gradient sufficient to reform easterly trades. Thus a more typical
trade wind pattern with any showers focused on windward/mauka
areas is expected to form late this week and lasting into early
next week. Some model guidance shows another moisture axis atop
Kauai around Sunday, while some has it staying north of the
islands. Trades may decrease somewhat by the middle of next week,
and another cold front may approach the state late next week.
