That low that you see located near North Carolina will be our weather-maker today, and it's a quick-moving one, as it will track out to the coast of Maine by 10:00 p.m. tonight, as shown in this GIF of the NAM model.

I think this will be a mostly snow event, though some areas could see some rain at the storm's onset. Speaking of the onset, it will be a struggle for the storm to get going, as there is a lot of dry air in the lower atmosphere that we need to overcome. Here's a look at the current HRRR model sounding for western CT:

The dew point at the surface and up to 800 mb is quite low, so any precipitation in the upper atmosphere that is forming at the moment is likely evaporating before reaching the surface, something called virga. A current radar image shows snow, though I suspect many are not yet seeing flakes.

As for snowfall totals, expect moderate amounts, with coastal areas favored:

Enjoy the quick-hitting storm, and enjoy the Super Bowl!
