Breezy to windy conditions are likely over the next few days as a
surface high well north of Hawaii produces a tight pressure
gradient for east-northeasterly trades. Some windward showers are
possible in this pattern, especially Wednesday to Friday across
the Big Island and Maui with some slightly increased instability
with a weak low aloft. By Friday, trades are forecast to weaken a
bit to more moderate to breezy levels, lasting through the
weekend. By early next week, ample tropical moisture is likely to
get pulled north as troughing at the surface and aloft produces
southerly flow. There is a signal for heavy rainfall but will
continue to monitor trends to refine the details.
