Now that the heaviest rainfall and the storms are behind us, flash flooding won't be a big issue, but areal flooding will. At times, Friday night's storms dropped rain at a rate of close to 7 inches an hour. The heavy rain rapidly overwhelmed area creeks, streams and drainage areas. Ponding and localized flooding will continue to be a problem. 

As forecasted, rain will shift to snow this afternoon and evening. Snow impacts will be minimal for the St. Louis metro area, most spots will only see trace to 0.5 inches of snow and a little ice. 

There is a winter weather advisory for Gasconade, Montgomery, Phelps, Dent, Crawford, Franklin, Warren, Lincoln and Pike counties. Those areas could see up to 2 inches of snow and 1/10 inch of ice.
