The pattern over Hawaii remains rather stagnant through about this
weekend as surface high pressure anchors north/northwest of Hawaii
with an upper level ridge over the state. This should result in a
fairly typical trade wind pattern and little in the way of rain
showers across the state. The latest guidance continues to suggest
that newly formed TD Three-E may approach the state around the
middle of next week. There does remain plenty of uncertainties in
the details and placement of this system, but current guidance
shows at least increased wind speeds and moisture ahead of its
approach towards Hawaii. Depending on the exact track of this
system (tropical or not by day 7), heavy rainfall could be
possible across portions of the islands. This system will need to
be monitored closely in the coming days for any potential impacts
on Hawaii around Wednesday of next week.
