While it stings that we're missing out on a legitimate late season snowfall in DC/Baltimore, I'm happy to see our Delmarva friends score a storm. We cash in so many times while they get stuck at 34 and drizzle.
The Frederick/Monocacy Valley seems to not do so well on marginal events without some kind of decent antecedent airmass. The only thing I can think of is that some warm air gets trapped at the surface to maybe the first 500 feet above ground.
Appreciate the report. There's definitely a little band setting up right along MD 97 into Carroll County. I polled some of the DOT cameras in that area and the roads and sidewalks are starting to cave.
