February 7 – This Super Bowl Sunday I have a super hard forecast. I know you don’t want to read much and honestly I don’t want to write much before the game begins. There are plenty of maps below for you to scroll through, including my first call for snowfall map, National Weather Service snow maps, and model forecasts. But I should show you how I think this system will develop as well. It is complicated as a major storm skirts just offshore, and a clipper from the west fades. A deformation zone will set up, not a well defined Low Pressure. So far, I am staying with everything I have been saying for the past few days. The hardest part about this forecast will be the set up for the moderate snow on Tuesday. There may be a narrow band, and that is where the heaviest snow will fall.
- It will snow this week!
- Starts: Rain changes to snow late Monday
- Main Event: Tuesday
- Deformation Zone (DZ): A pump in the atmosphere ‘between’ the surface Low and upper level Low.
- Models differ where that will set up. So snow potential on models range from barely 1″ to well over 6″ around metro Baltimore.
- A narrow band of moderate snow on Tuesday will be the focus for highest amount in the DZ
- Snow Showers Linger: Wednesday and Thursday
- Cold Will Hold: Temps stay below average through next week

This is the model that has performed the best in the past month. It is also the most aggressive with snow between Baltimore Maryland and York Pennsylvania.
