The first substantial chance of winter weather might be heading our way tomorrow night. The various models seem to point to an accumulating snow event along the Appalachian mountains. In Richmond, the NWS still has the metro area in 100% rain. Areas like Short Pump and Powhatan have a slight chance of the precipitation changing to snow.

The chance of accumulating snow for Richmond remains very low. However, we could see a rain to snow changeover on the tail end of the precipitation shield. This scenario will likely preclude any meaningful accumulation. It will be worth watching to see how the event pans out for Metro Richmond.
