The weather is looking better for Sunday morning. Details later

A series of weak disturbances emanating from a low pressure system in the Midwest will pass through, mostly during the nighttime hours Friday through Saturday night.

For Saturday, showers Friday night will move away, allowing partial clearing, some sun and dry conditions for much of the daytime Saturday.  High temperatures 76-80 (EKDMOS) or 75 (NBM). Light winds.

The main surface low pressure system approaches late Saturday into Saturday night. Rain develops, possibly heavy before daybreak Sunday.

There remain some differences in the forecast for Sunday and the Broad Street Run

The GFS has the low pressure system exiting by mid-morning with rain decreasing considerably.

The latest FV3-GFS and the NAM show an upper air disturbance causing a slowing of the exit of the surface low with considerable rain for much of the day, tapering in the afternoon. High temperatures 65-68 (EKDMOS- with large statistical spread)  or 63 (NBM). Fairly windy in the morning.

I’ll update this evening about 11 PM.
