It seems that globals tonight at 00z must be getting some new data that they’ve all made this shift to a colder/snowier solution. Euro will be telling in an hour.
While we wait for UK and Euro, I wanted to share 850s on the CMC too. While CMC evolution is different than the GFS, similar story with colder solution than CMC 12z.
Pretty amazing difference on the GFS with 850 temps. At its warmest, 18z had the 850 line just west of Dulles into Loudoun County while 00z keeps it down in Charles County, MD.
ICON is a terrible model but I’d much rather see this to kick off 00z than the other way around. Just go with the snowiest model, common sense be damned.
