Trade winds are forecast to gradually strengthen early this week
across Hawaii, as 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-moderate trades is forecast over the next day or
so, while cloudiness and showers decrease from the western islands
as moisture moves out. A typical trade wind pattern with windward
and mauka showers and drier leeward areas starts to take hold
Monday and beyond, with generally average to below average
moisture expected through midweek aside from possibly a brief
period of increased moisture around Monday. 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--so, trades are likely to strengthen
given lowering pressure to the south. By next weekend, another
possible tropical system could bring another, potentially better
chance of increased moisture coming into Hawaii, but with ample
uncertainty at this point.
