February 6 – The groundhog was wrong! Winter will be fighting back next week with a strong arctic surge and there will be snow with it. The first thing I want to say is that there will be a lot of energy in the atmosphere but it is not eel organized. But as one system races off the coast, and a clipper fades in the Great Lakes, there will be a weakness in the atmosphere overhead that will fill in with snow. In fact, I have a new way to measure snow that I will show below.
The main idea is the time frame late Monday through Wednesday. I see rain changing to snow as the system evolves overhead. Literally! Arctic air will build as a trough in the jet steam settles over the Eastern US. Watch as it grows colder during the week. Then see the scattered upper level energy and surface maps below. The main snow event will be Tuesday, and there will be enough to shovel. But I will not give any potential snow amounts until tomorrow (Sunday= 48 hours away).
