Hmmm...concerning. Evening run of IBM's GRAF model is trying to dump ½-2" wet snow central/east metro briefly 1-4am tonight in intense precip band (remember Saturday night the 18th?), then back to rain. It's the only model producing such widespread metro snow. Watching closely! pic.twitter.com/bUNQFASMKs
