A frontal boundary has stalled to the north of the state and is
forecast to die quickly, but has served to disrupt the typical
trade wind pattern leading to a land and sea breeze pattern
lasting through Saturday. But into early next week, trades look to
increase again to around moderate levels with a relatively weak
surface ridge poking in from the east, and then could strengthen
further from the northeasterly direction by Tuesday-Wednesday as a
surface high comes in from the northwest. The pattern may allow
for some windward/mauka showers, especially as moisture could pool
ahead of another cold front that should be north of Hawaii through
midweek. The latest model guidance is reasonably agreeable that
this front should push progressively southward through at least
most of the state during the latter part of next week, though
models certainly could diverge again in future cycles. Gusty
northeasterly winds and lower dewpoints are forecast behind the
front.
