Arks will be needed for Thanksgiving Week

Social media chatter has continued about the big storm and possible snow.

Looks like the rain will start early Tuesday for most of the Lynchburg and Roanoke areas and it will POUR.
2-4 inches of RAIN very likely region wide.
Red are is OVER 3 inches.

2 possible winter precipitation events in this...

1. As it starts, cooler dried air will be in place with temps near freezing. A quick burst of sleet could transition to some freezing rain for a couple hours Tuesday AM. 
2. As the low winds down, colder air is filtering in behind and depending on that speed plus the upper air low, some model data suggest it ends as snow. Some model data says just light snow and flurries while others drop a coating to an inch or more. (Few runs of Euro drop 3-4 inches in both Lynchburg and Roanoke)

My take-- these lows with trailing upper lows are tricky and fickle-- would not be shocking if NO flurries fell and would not be shocked if 1-2 inches of snow on the backside. Let's play conservative as of now and go with NO accumulations, but ending as snow. Mountain areas will do a little better.
