ST. LOUIS — A winter weather system moving through the Gulf States will bring light snow to parts of Missouri and Illinois on Friday, though forecasters expect minimal impact compared to recent storms.

The National Weather Service in St. Louis reports the snow should start Thursday evening. While accumulation is possible, meteorologist John Fuller says the system’s southern trajectory will result in lighter snowfall amounts than previous winter storms this season.

The incoming snow arrives amid an Arctic air mass that has kept local temperatures in the 20s, with wind chills between 14 and 20 degrees. The frigid conditions are expected to last through the end of the week, with overnight lows potentially dropping into single digits in areas outside the city.
