Warning Description: Special Statement Warning Date: 3:56 PM CST on January 27, 2012 WarningSum:...Light Snow Accumulations Expected Across Parts Of The Area Tonight... Warning Message:A fast moving weather system will track across the area tonight bringing accumulating snow to portions of the area. The precipitation may begin as rain before changing to a rain and snow mix...and then eventually changing to all snow. The quickest changeover to all snow should occur across northeast Missouri and west central Illinois where snow accumulations of up to 2 inches are possible. Further south along the Interstate 70 corridor from Columbia to St Louis to Vandalia...this transition from rain to snow will be slower and occur as the evening progresses. Total snow accumulations within this area should be an inch or less. Most of the snowfall accumulation should be confined to grassy surfaces...but untreated roads could become snow covered once the temperature lowers to freezing. Motorists should be aware while traveling tonight and be prepared for adverse driving conditions if the roads become snow covered. Glass
