This time of year it's all about direction

The recent snowfall across the upper Midwest and Great Lakes this past weekend can, and often does, affect our weather locally.  This time of year it's all about wind direction.  As wind moves across a snow covered land mass the cold surface of the ground will help modify and cool that air mass often times keeping temperatures cooler than they normally would be if there were little or no snow on the ground.

These next few days we won't have to worry about a northwest wind.  A series of quick moving systems will move across the Midwest and Great Lakes keeping northern Illinois locked in a southwest flow.  This will allow temperatures to warm through the 40s by the end of the week.
