Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 645 AM EDT Tue Jul 22 2014 Valid 00Z Wed Jul 23 2014 - 00Z Wed Jul 30 2014 The models indicate that there will still be some moisture backwash in the wake of Wali through Wednesday night. After that, Hawai'i will remain vulnerable to minor easterly waves which will disrupt the trades from time to time. The 00Z/22 high-resolution ECMWF shows a more substantial tropical wave passing to the south of the state early next week. Will have to keep an eye on that system. Rainfall during the next week should be on the order of a tenth to a quarter of an inch statewide, with several inches possible in the favored terrain--particularly the western side of the Big Island.
