Tonight: 24. Mostly cloudy. Winds: North northeast 5 mph.

A Winter Weather Advisory is in effect Tuesday evening for the St. Louis metro, a little earlier to the south where the snow develops first. The advisory will continue into Wednesday morning.


Tuesday: 37. Mostly cloudy. Slight chance of snow in the late afternoon, then snow likely in the evening.  For St. Louis a brief band of snow/sleet may develop by late afternoon to early evening, with the main push of snow accumulation near 7PM to Midnight.  Some forecast models hold off until closer to 9PM.  Look for snow to be briefly heavy at times Tuesday evening and roads can become snow-covered quickly. Right now, much of the area could see 1" to 3" of snow, most of which comes down Tuesday evening in a short span before midnight in St. Louis. 


Overnight Into Wednesday Morning: 30 and Rising to 33 By 6 AM. Late Tuesday evening and overnight snow tapers off as a wintry mix with some sleet and then some freezing drizzle. A light glazing is possible Tuesday night. We'll have to watch the Wednesday morning commute to make sure any snow/icy areas have melted off by the Wednesday morning drive with a temperature right around or just above freezing. The trend is for temperatures to continue to warm and roads will turn just wet Wednesday morning.
