A low pressure system currently moving across the Plains will bring snow to the Midwest tonight into tomorrow.
Accumulations will range from a few inches to a dusting.
Chicago, IL will receive a dusting, but St. Louis, MO may receive a couple of inches.
Below is the infrared satellite displaying the system progressing eastward.
As the system treks east, I am expecting it to weaken, as the satellite imagery shows how weak it already is.
So don't be surprised to see some flakes falling; it should make for a nice evening... unless you live up north where the temperature is 0!
