I don’t think anyone had DD from that airmass in SNE. Wasn’t it really windy? I remember ORH doing -10° or something in that. DD is basically the frozen form of fog…a cirrus cloud at the sfc.
Yeah let’s get those airmasses inside d7 without a moderating trend. But yeah, looks cold overall and potentially active either way. Although the 6z goofus had some creative ways to screw AEMATT despite cold and high QPF.
Op/details/6z gfs aside…
That was kind of a fun run to loop through seeing those massive, sprawling 1040+ highs sandwiched around shortwaves trying to barge through the cold. @WxWatcher007 would get his -35° at SLK under one of those highs.
