[Technical post] I find this kind of storm setup SUPER interesting. Strong WAA to the NW of the Low gives this really nice FGEN through 800-600mb, DGZ included. Combine that with terrain influences and there's potential for a strongly forced snow band over Rt. 29. #vawx

This isn't a "Boom" snow forecast, I just find the atmospheric dynamics at work here really cool to watch. Isentropic lift forces this mid level "Squeeze" that can often nudge up QPF and increase snow rates to overcome marginal surface temps for accumulation.
For a more detailed explanation on FGEN and its impacts on the snow forecast, check out this fantastic thread by @WXReese going into detail for the Charlottesville area. #vawx https://twitter.com/WXReese/status/1357708650031296513?s=20
