ST. LOUIS, MO (KTVI)- As December gets rolling, winter snow and sleet gets to be more and more of a possibility. The St. Louis area will see a taste of that late Saturday night and into Sunday morning. A dry air mass over St. Louis held back a big southern storm Saturday. But overnight, rain showers will spread across the region. As that rain moves in, overnight temperatures will be cold enough that it may mix with some sleet or wet snow.
With mostly rain falling and warm ground temperatures, most won't see any accumulation. The exception would be with our far northern tier counties who could maybe seeing a dusting on grassy surfaces between about 4:00am and 8:00am.
Everything changes back to all rain as we warm up Sunday morning. The precipitation exits to the east in the afternoon.
The next storm system comes at us from the southwest for an all rain event Monday night and into Tuesday. Then ,get ready. A shot of very cold air rolls our way on Wednesday. Looks like we see a chance of light snow Wednesday afternoon and night. Then the coldest air of the season so-far arrives for Thursday into Friday. By Friday morning, temperatures will be in the low teens with wind chills near 0°.
