A reasonably strong high pressure system well to the north of
Hawaii is promoting breezy easterly trade winds across the state,
which should continue through the latter part of the week. This
could be a wet trade wind pattern with showers over windward and
mountain areas as remnant moisture lingers from a front that has
now dissipated. This weak band of moisture is forecast to push
slowly southward and another minor moisture increase is possible
over the weekend, while a period of mid-upper ridging should
weaken trades somewhat. By next Monday-Wednesday, weak upper
troughing is expected to move back over Hawaii, possibly providing
some instability for shower activity. Recent model guidance still
indicates the potential for enhanced moisture coming in from the
south by the latter half of next week. This could also increase
shower coverage, but there is uncertainty in the timing and
location details at this point.
