Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 735 AM EDT Mon Apr 27 2015 Valid 00Z Tue Apr 28 2015 - 00Z Tue May 05 2015 The 27/00Z ECENS/GEFS and their deterministic runs were in very good agreement with the current Hawai'i forecast through day 7. Near-term sensible weather is associated with a cold front migration poised to exit the eastern fringes of the forecast area in the next 24 hours. Surface high and rather substantial mid-level ridge---on cue---to migrate across the central Pacific behind the front---and through Thursday will enhance the tradewind flow pattern. By Friday (day 5), the surface ridge begins to migrate northeastward and the gradient winds/trade winds should be easing across the forecast area. Vojtesak
