St. Louis, Missouri – Snow is spreading across west-central Illinois and northeast Missouri this morning, creating hazardous travel conditions that could linger into Sunday evening as a slow-moving winter system settles over the region.
According to the National Weather Service in St. Louis, a Winter Weather Advisory remains in effect from Saturday morning through Sunday evening for Adams and Brown counties in Illinois, along with Knox, Lewis, Shelby, Marion, and Monroe counties in Missouri. Snow totals are expected to range between 2 and 4 inches, with steady accumulation developing after midmorning and continuing at times through Sunday.
Communities including Quincy, Mount Sterling, and Hannibal are likely to see snow-covered roads by late morning Saturday, with conditions deteriorating as temperatures remain cold enough for snow to stick on untreated surfaces. In northeast Missouri, rural highways and secondary roads could become slick quickly, especially during heavier bursts of snowfall.
Transportation officials urge drivers to slow down, increase following distance, and avoid unnecessary travel during periods of steady snow.

Snow is expected to taper Sunday evening, though lingering slick spots could persist overnight. Additional advisories remain possible if snowfall rates increase or conditions worsen.
