ST. LOUIS – After a quick taste of spring-like temperatures another system will bring back colder weather and our next round of wintry precipitation. The next storm system is already making its way into the St. Louis region. Spotty showers will develop for Monday night. Widespread rain will be possible on and off through the day on Tuesday. Temperatures will be falling through the day on Tuesday and will dip down into the 30°s by about noon.
Later on Tuesday evening into Tuesday night, some light icing will be possible west of St. Louis as temperatures fall below freezing. On Wednesday, precipitation will turn into a wintry mix and then eventually all snow. A band of accumulating snow may set up over part of the viewing area. It’s still very early to start talking specific accumulations, but part of the region could see up to 3″ of snow.
Mon 5:20a: Here are the forecast accumulation maps for the #winter weather on Tue-Thu. Most of the #snow will fall on Wed/Wed night. Most of the #ice will occur on Tue/Tue night. #stlwx #midmowx #mowx #ilwx pic.twitter.com/NONhMGZrUt
