Starting to think this might be real. Euro even has MBY around freezing when it falls. Sun angle yah…but think there’s a decent shot at measuring something and taking a wintry Jebwalk, so those are wins.
RGEM is a nice period of snow for Baltimore area but temps mostly above freezing. GFS shows temps at or even slightly below freezing. 3k NAM has a flurry maybe?
There’s good reasons to think a stout -NAO will develop at some time with SSW downwelling support. Shorter wavelengths would help mute a hostile Pac longwave configuration, but until it happens, I won’t trust it given persistence.
