A west-east oriented ridge aloft continues to promote clement and
relatively dry conditions over Hawaii, which should last through
the rest of this week into early next week. Meanwhile a front is
forecast to stall and dissipate north of the state late this week,
allowing winds to turn a bit southeasterly in response, but
overall weakening so that a land/sea breeze pattern dominates.
Then trades may restrengthen a bit by the weekend into early next
week, but perhaps only to levels that promote a hybrid land/sea
breezes and trades pattern. The lack of deep moisture with the
ridge aloft should keep precipitation limited. By around Tuesday,
a cold front looks to move across Hawaii. Model guidance does not
show much of an increase in rain chances associated with this
front at this point, maintaining overall dry weather. But the
front would at least shift winds to have a northerly component and
strengthen them as the pressure gradient increases with a surface
high behind the front.
