1 to 3 inches of snow fell east of the Mississippi River Saturday night

A strong disturbance in the upper levels of the atmosphere moved eastward across Arkansas, then northeast into the Ohio Valley on Saturday evening. As cold air rushed southeast, rain associated with the upper level disturbance changed to snow. Average snowfall amounts ranged from 1 to 3 inches over western Kentucky, southeast Illinois, and southwest Indiana. Little or no snow was reported in southeast Missouri and southwest Illinois, which was too far west of the path of the disturbance.

Northwest winds gusting up to 35 mph brought wind chills down to around zero by early Sunday morning.

Temperatures in the 50's prior to this snow event warmed pavement temperatures sufficiently to melt the snow on contact initially. As the snow ended, temperatures plunged through the 20's, resulting in a frozen layer of slush on untreated surfaces.
