Great post Robert. Looks like similar conditions to the horrible cold snap in Florida in 1977. If some model guidance is correct, it may snow very lightly as far south as the I-4 corridor in central Florida this weekend.
We're expecting -20s tonight in North Dakota again (a few -30s perhaps), which really isn't "crazy" cold by our standards, but certainly much different in the deep south.
Next week looks better. Hang in there.
