Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
825 AM EDT Sat Mar 21 2015

Valid 00Z Sun Mar 22 2015 - 00Z Sun Mar 29 2015

Surface high pressure will pass eastward along 30N over the next
few days. 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 before falling later next week. GEFS members
were still just a bit drier than the ECMWF ensemble members and a
compromise between their operational counterparts seems
sufficient. Another high pressure to the north by later next week
will bring in fresh trades and quiet weather.
