A light snow event affected the Aurora area on Saturday. The snowfall was brief and amounts were small across the area. Some drizzle and freezing drizzle is possible across the area tonight.
An open wave that originated in the southwest United States pushed into the area today. This wave dumped several inches of snow across southwest Texas. This met up with a clipper moving into the Great Lakes from the northwest and reinforcing cold air. The end result was a period of snow across the area.
Officially, O'Hare Airport only picked up 0.4 inches of snow. Oak Brook and St. Charles picked up 0.3 inches. Most of this fell in a very short period of time with ground temperatures above freezing, so large accumulations were not anticipated. With little additional snow expected, the area will still be lacking a 1 inch snowfall on a calendar day this season. This will be the 316th consecutive day without one. The record is 319 days without a one inch snow set back in 1940. These numbers were found from National Weather Service statistics.
Freezing drizzle is possible across Aurora tonight. As the storm system is pulling out, the upper levels are drying out. This is where snow is produced, so this is winding down. The lower levels will remain moist. This moisture will drizzle its way down to a surface that will be below freezing overnight. Exercise caution when driving!
