Trade winds should be strengthening back to breezy levels on
Sunday as a surface high drifts toward Hawaii (though staying well
north). The high is forecast to meander around 40N and maintain
the typical pressure gradient for breezy easterly trades through
much of this week, with some model signal to strengthen even
further by late week. Through the period, some showers are
possible favoring typical windward/mauka areas but occasionally
spilling into leeward areas. Coverage and amounts of rain may vary
from day to day. By around Wednesday-Friday, troughing in the
mid-upper levels could support more surges of moisture, but models
do not necessarily show higher rain amounts for those days, so
will continue to monitor. Widespread heavy rain is not expected,
just a relatively wet trade wind pattern.
