Quiet weather is expected across Hawaii today/Tuesday as trade
winds should be around moderate levels and the upper low weakens
and pulls away. Mid-upper ridging looks to build in its place,
which will increase stability and lessen chances for too many
showers. Meanwhile a Pacific high is forecast to move southwest
closer to the state, with its influence extending to increase
easterly trades to breezy levels Wednesday-Thursday and perhaps
strengthening further to windy levels by Friday and continuing
through the weekend into early next week. Any showers that do form
should favor windward areas, but widespread rain is not expected.
There is some signal for more of a trough pattern aloft to come in
by next Monday-Tuesday, but not with a notable surface pattern
change or increasing moisture, but this will continue to be
monitored.
