This is a short analysis because we only will focus on one model. The latest NAM has just come out, and we will focus on this. Below is hour 84 simulated radar.
Note the potential squall line in the Ohio Valley. Also, the big bulk of precipitation in the Great Lakes, Midwest. To sort out whether the precipitation is snow or rain, see below.
The farthest south BLUE line is the rain/snow line. Precipitation will be heavy closest to the line in this storm.
This has been the first of potentially many analyses on this storm.
