The latest models and ensembles show good agreement on an upper
low staying well to the north of Hawaii and a cold front settling
near/over the western part of the state into early next 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, although much
of the latest guidance suggests the heaviest rainfall may stay
just to the north/west. Around Wednesday of next week, guidance
shows the upper low lifting north and eastward and heights rising
again over Hawaii, with lighter trades and some lingering showery
activity.
