Must Be Tough

Area forecast discussion

National Weather Service Honolulu HI
400 PM HST Wednesday Aug 27 2008

Synopsis... moderate trade winds are expected through the end of the week. A slight decrease in winds is expected during the weekend...but look for winds to increase again next week. Trade wind showers will favor windward and Mauka areas.

Discussion... good model agreement with a high pressure ridge north of the state being the main weather feature during the forecast period. A low pressure system moving in from the west will help to disrupt the ridge...despite the fact that the low is expected to move north along the west side of the ridge. This interaction will reduce the trade winds over the islands a bit this weekend. The band of clouds upstream of the islands remains over Oahu and Maui County this afternoon.

As a result...have made some minor modifications to various areas with regards to probability of precipitation for the first part of the night. Rainfall over the windward areas was in the neighborhood of a quarter to a third of in from Kauai to Maui...with no rain reported by The Big Island rain gages. The most rain fell at the Ulupalakua gage on Maui where the gage reported 0.49 inches between 1 and 2 PM.

Hfo watches/warnings/advisories... none.
