Beginning Sunday afternoon, snow moved into the metro-east area and other wintry precipitation was expected through the rest of the week.
According to St. Louis’ U.S. National Weather Service base, a fast-moving winter system was expected to move eastward through central Missouri and southern Illinois beginning Sunday.
Snow accumulation in the metro-east area was expected to be less than one inch Sunday and, according to Weather Underground, was expected to end by 6:15 p.m.
A post from St. Clair County Emergency Management on Sunday afternoon showed several cars that appeared to either have driven off the road or pulled over on the Interstate 64 ramp at Green Mount Road.
Another post warned drivers of slick road conditions.
“There is NOT a significant accumulation expected from this snowfall, however, the roadways are becoming slick and some accidents are occurring. Please exercise caution as you travel to your evening parties,” the post read.
Sunday forecasts predicted two periods of snow from Monday through Tuesday night, according to the NWS. The first round of snow was predicted to hit from Monday afternoon into the evening with accumulations ranging from a dusting to an inch.
“A more widespread threat of snow is expected Tuesday through Tuesday night. Will see freezing rain and sleet mixed in at times over portions of southeast Missouri and Southern Illinois,” a post from NWS read Sunday.
Snow accumulations on Tuesday were predicted to range from half an inch to three to four inches along and south of Interstate 70. The NWS also predicted potential light ice over the region.
“Remember … uncertainty remains in the track of the storm systems and totals are subject to change,” a NWS post read.
A large crash on Interstate 44 in Rolla caused eastbound lanes to close Sunday night, according to KMOV. The Missouri State Highway Patrol warned of slick roads in the area.
