St. Louis, MO — Another quick-moving winter system will bring a fresh round of snow to northeast Missouri and central Illinois on Saturday, with travel impacts possible wherever snow falls, according to the National Weather Service in St. Louis.
Forecasters say confidence is increasing that the region will see light to moderate snowfall, though the precise placement of the heaviest band remains uncertain. Early projections show a corridor of 2–4 inches possible across parts of northeast Missouri and west-central Illinois, including areas near Quincy, Hannibal, Macomb, and Springfield, IL. Slight shifts north or south remain possible through Saturday morning.
According to the National Weather Service, temperatures will stay well below freezing throughout the event. As a result, even minor accumulations may create slick roads, especially on untreated surfaces. Drivers traveling Saturday should prepare for reduced visibility, patchy snow-covered roads, and rapidly changing conditions along the heaviest band of snow.
For the St. Louis metro, totals remain more uncertain, but forecasters note that any snow that does fall will accumulate quickly due to the cold ground.
Impacts may peak late morning through afternoon before tapering from west to east. The agency urges travelers to check updated forecasts and road conditions before heading out, as small shifts in the storm track could alter where the highest totals occur.
A quieter, colder pattern settles in Saturday night, with temperatures remaining below normal into early next week.
