As of mid-morning the center of the sprawling low pressure system was located over the lower Ohio and Tennessee Valleys. Snow was falling from Missouri east through Illinois and north into Iowa. The system is being fed by an ample supply of moisture from the Gulf of Mexico, and that combined with the strong upper level system is producing heavy snow from eastern Missouri through central Illinois. CoCoRaHS observers have reported snowfall rates of 2 inches per hour. There is a possibility for thundersnow in the southern portion of the heavy snow band.
Snow accumulations will be heavy with this storm. There is a high probability of 4 inches or more from central Missouri to western Virginia, and a good chance of 8 inches or more within this band.from eastern Missouri into southern Indiana, as well as in the mountains in western Virginia. As of 1:45 pm CDT today 6 to 8 inches has already accumulated in west-central and central Illinois with heavy snow still falling.
