Trade winds are forecast to gradually strengthen this weekend and
beyond as a small upper low lifts away and the pressure gradient
strengthens a bit as the typical Pacific surface high well
north-northeast of the state takes hold again. Thus a somewhat
hybrid pattern of land/sea breezes and light trades is forecast
over the next day or so, before a typical trade wind pattern with
windward and mauka showers and drier leeward areas starts to take
hold early next week. Some brief increases in moisture and thus
possibly shower coverage are possible this weekend into next week,
with general model signals for this late Saturday and also
Monday-Tuesday. After that, there is some chance that enhanced
moisture with a potential tropical system around mid-late next
week could make its way into Hawaii. At least the highest moisture
anomalies are likely to stay south, but the possibility that some
could stream into the state will continue to be monitored. The
strength of the trade winds will also depend on the pressure
gradient that will be affected by the possible tropical
development.
