Guidance reasonably agrees that height falls and general upper
troughing will shift gradually westward over the state and
vicinity through the next few days in a pattern with disrupted
island trades and land/sea breezes, but below normal moisture will
limit shower activity. A guidance composite is preferred to
mitigate smaller scale differences consistent with predictability.
Trades may be slow to return through next weekend. Howeevr, deeper
tropical moisture may reach/skirt the southern islands mid-late
week to fuel some localized downpours, mainly over the Big Island.
Otherwise, expect slow to rise heights in the wake of upper trough
passage into late week and next weekend and a return to below
normal moisture availability and shower activity.
