Spring Cool Down Brings Snow to Midwest

A significant cooldown has swept into parts of the Midwest and Northeast, so hopefully you haven't put away your jacket yet after enjoying a taste of spring last week.

This flip to a cooler temperature regime is due to an upper-level trough that has dipped southward into the Midwest, dragging modified Canadian air from the northern Plains to the Northeast. This upper-level trough will make slow progress eastward which will allow the cool temperatures to remain in place.

The air mass has even been cold enough for snow in some locations.

As of Wednesday night, up to 12 inches of snow was reported in Bessemer, Michigan. Some higher terrain locations in western Pennsylvania, western Maryland and northern West Virginia have also seen a few inches of snow.
