Thursday's Light Snow Event and Unique Snow Band

Thursday, November 15 saw early morning snow from a major weather system to our south spread northwest over northwest Indiana and northern Illinois. The solid snow shield brought 2" to 4" of accumulation in parts of east central Illinois into northwest Indiana by mid-morning. Then a single band of snow continued to move northwest across the Chicago metro area, pivoting, and then weakened as it moved back southeast (though did briefly re-intensify). This band produced mainly 1-2", although there was isolated 2" in Lake County, IL.

Radar Loop from Nov 15,12 a.m. - 6 p.m. Note the colors represent estimated precipitation type. Almost all of this was observed to have been snow.
