The map below shows where the significant snow will fall Sunday into Monday. The storm is no different than what we have seen this winter. Weak waves of low pressure running along an arctic front are causing heavy snows north of the front. This time, the air mass south of the front is getting warmer and more humid, so the QPF will be higher and the snow heavier. I can see well over a foot of snow for areas from Ohio into southern New England.
Severe weather is possible across the lower Mississippi Valley. It would appear that impacts will be damaging wind gusts and flooding rains.
A blizzard will hit the West and northern Plains. After that, a shot of cold weather will bring lake snow this weekend.
