The GFS forecast appears to be on-track for today. It will be raining for the entire day, with heaviest rain late afternoon (4 PM) into the early evening.
Some uncertainty about Sunday’s cloud cover. The cyclonic flow will result in some degree of cloudiness with sunshine. The NAM suggests the possibility of a brief shower Sunday afternoon due to instability.
The forecast remains essentially unchanged. Low pressure and an easterly flow will bring rain for much of Saturday. Rain will begin by mid to late Saturday morning and become heavier into the afternoon and evening. There’s a chance of embedded thunderstorms late afternoon. Windy with temperatures near 70. The latest models have backed away from the multiple inches of rain here, but locally heavy rain with convective thunderstorms is possible.
For Sunday, the rain ends before daybreak , but a cyclonic flow will keep the skies from fully clearing. So a mix of sun and clouds with temperatures near 80.
