Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 827 AM EDT Thu Mar 26 2015 Valid 00Z Fri Mar 27 2015 - 00Z Fri Apr 03 2015 The models and ensembles reasonably agree that a building ridge over the state over the next couple of days should gradually limit island showers in the wake of supporting shortwave passage to the northeast and associated trailing/stalled surface boundary weakening. Showers should linger mostly over the southern islands over the next 48 hours. Trades will kick in this period. Additional shortwave passage to the north of the state around Sunday should whittle into the ambient ridge and allow some moisture return. This leads into stronger southern stream impulse energy and height falls working more ernestly into the state around Tuesday along with deeper moisture to fuel a pattern with more widespread showers through next midweek. This is all based on a favored guidance composite given modest forecast spread, albeit with some latter period timing issues inherent with smaller scale systems. Schichtel
