lol, as the wave/heavy slug of moisture comes, it does this weird thing by pushing the freezline back north of HGR and it's south to just northeast of DC and south of ANnapolis.  I can't describe it..youll have to see it.  It's above freezing in Winchester and DC, but below freezing in Annapolis. Columbia and....Queen anne county.

I noticed this on the models the last several days.  Bay is cold and kind of frozen wonder if it seeing that? Also on my drive today Annapolis was colder then MoCo county.

Time to call in a specialist for this threat.

I think for the DC crew, it’s a non event on the latest guidance. I know you live in western HoCo. I wouldn’t be pulling the plug in your hood. Parrs Ridge area down to northern MoCo could still be a mess. I think the areas north of I-70 are in the best shape for ice. Climo winning again
