SW Flow...Models No Go

Yesterday's VIPIR run said there would be some showers during tonight's parades. The WSI RPM model run had all the rain north of the Lake with the parades staying dry. VIPIR 1, RPM 0. Tonight VIPIR says tomorrow night's parades will be dry. The RPM model lingers some showers into parade time. What's going on? Why no "consensus"? My experience shows me that anytime we get into this SW Upper Flow pattern, the computer models have great trouble on the timing of minor disturbances racing through the flow. That's why I have low confidence on the forecasts for the next 2-3 days. Both models bring stronger storms over us on Saturday morning into the PM so at the moment, Saturday's parades will likely have to be rescheduled .but that could change if the upper disturbance moves through faster than predicted. Stay tuned!
