Snow began in southeast Missouri during the early to mid morning hours, before spreading eastward across southern Illinois through the early afternoon. Highest amounts were focused across the Ozark Foothills of southeast Missouri, aided by the earlier start time of the snow and colder air and ground temperatures. Further east (over southern Illinois), the snow began around midday, when air and ground temperatures had already warmed well above freezing. This made it difficult for snow to accumulate, and what did manage to stick melted rather quickly after the snow ended. Total accumulations ranged from one to three inches, with the highest amounts north and west of Carbondale, including the Interstate 64 corridor. The snow was caused by a low pressure system that tracked northeast from the central Gulf coast to the northeast Georgia mountains.
