First Winter Storm Potential Next Week

Well, well, well. It looks like winter IS going to come after all, as expected. I, along with many other people, have been saying that there will be a pattern change coming soon in January. Well, it looks like we could potentially be seeing our first winter storm of the season next week. Could this be the “season changer” that we’ve been waiting for?

The storm setup is looking like this: a low pressure system forms in the South in Texas, bringing a mess of weather early next week to the South and into the Midwest. The storm moves NE into the Northeast, where the problem will be for us. A high pressure system will be placed north of us in Canada. A CAD (Cold Air Damming) event looks like it may take place. This could bring a quick burst of snow at the start of the system in NE Pennsylvania, NW New Jersey, and New England, before warmer air takes over, changing the quick burst of snow to ice then quickly to rain. An earlier run had the low redeveloping off the coast of New Jersey, changing the rain in New England back to snow in areas before exiting. The latest run (18z) of the GFS no longer shows this happening. This is the GFS timeline shown below, from the 18z run on Wednesday, December 23rd:
