A Taste of Wintry Weather Tomorrow...

A cold rain will spread over the region from the south during the wee hours of the morning as low pressure develops along the coast. The rain will continue through much of Saturday, mixing with some snow well west of Interstate 95. As the storm moves north-northeast and pulls away from the area, colder air will continue to take hold. As our temperature profile gets colder, we'll see a changeover to snow from west to east by late afternoon and evening. An upper level disturbance will keep enough moisture over the region to produce some snow during the evening in Metro Richmond and possibly even points east towards the coast. With the relatively warm ground temperatures, I don't expect much accumulation. However, being that it will be nighttime and temperatures will be lowering through the 30s, I think we could see some minor accumulation on grassy surfaces, decks, etc. Road surfaces should remain wet. Well to the north and west of Richmond, from western Goochland and Hanover back to Charlottesville, I wouldn't be surprised to see an inch or two of accumulation, with some local amounts of 3 inches.
