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.
