While the Mid-Atlantic region is digging out from The Winter Powerhouse they should also keep an eye on the next storm that could be moving in on them Tuesday into Wednesday.

That next storm actually forms out of two separate systems that impact the northern and southern Plains overnight and Monday.

The northern system brings a long period of mainly light snow to the eastern Plains and upper Mississippi Valley through late Monday night and Tuesday morning. There could be a wide swath of heavy snow by the time the storm ends.

Snow from the northern system spreads into the lower Great Lakes and Ohio Valley Monday afternoon through Tuesday.

The southern system moves out of the New Mexico Rockies overnight and through the southern Plains Monday.

Accumulating snow should extend from southern Colorado and northern New Mexico through the Texas and Oklahoma panhandles through northern Oklahoma and southern Kansas to western Missouri and northernmost Arkansas through Monday night.

The heaviest accumulations should occur in the southern Rockies where up to 40cms is possible.

By Tuesday the northern and southern systems combine and head toward the Mid-Atlantic and Northeast.
