Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 803 AM EDT Fri Mar 20 2015 Valid 00Z Sat Mar 21 2015 - 00Z Sat Mar 28 2015 Weakening surface boundary will wash out over the next 24 hours with generally light/scattered showers in windward areas. More typical easterly trades will resume as surface high pressure passes eastward along 30N this weekend. A quiet/drier stretch of weather should ensue until about mid-week next week with good agreement among the guidance. Next possible cold frontal passage or shear axis would be around next Wednesday. QPF should be fairly light with forecast PW values only around one inch. GEFS members were a bit drier than the ECMWF ensemble members - a compromise seems sufficient. Fracasso
