Models and ensembles still reasonably agree that a building ridge
over the state will limit island showers to trade favored windward
slopes and near a weakening surface boundary. Showers linger
mostly over the southern islands over the next 24-48 hours.
Shortwave passage north of the state Sunday whittles into the
ridge and allows some moisture return. This leads into stronger
southern stream impulse energy and height falls working more
ernestly into the state starting Tuesday along with deeper
moisture to fuel a pattern with more widespread shower potenital
through next midweek. This scenario remains based on a favored
guidance composite given modest forecast spread, albeit with some
latter period timing issues inherent with smaller scale systems.
