The latest models and ensembles show good agreement on an upper
low staying well to the north of Hawaii and a cold front
meandering near/over the western part of the state during the
early part of the week. Trade winds should shift to a more
southerly direction and strengthen ahead of the approaching front
with enhanced moisture and rainfall across especially the western
islands. Enhanced showery activity is also possible across parts
of the Big Island/Maui associated with weak energy and a pocket of
higher moisture. Around Wednesday, the upper low should begin
lifting north and east with heights rising again over Hawaii
through the rest of the week. Trade winds should trend very light
mid to late week, with a typical land/sea breeze pattern, but
trades may veer and strengthen again next weekend as a new cold
front moves into the region with additional showers possible.
