ST. LOUIS — This week’s winter storm is here, bringing snow across the area through early Wednesday morning.
Tuesday morning:
Light snow is moving through the region, with up to 1 inch of accumulation overnight. Snow is sticking to roads due to the bitter cold, making for a slick morning commute. Winds are also blowing the powdery snow around, reducing visibility.
Tuesday afternoon and evening:
A heavier round of snow arrives in the afternoon and continues into the night. The heaviest snow will fall south of I-70, where snowfall rates could exceed an inch per hour. North of I-70, including St. Louis, totals will be lower due to colder, drier air pushing the storm south.
Early Wednesday:
Snow tapers off before sunrise, but roads will remain snow-covered and icy.
What to expect:
- Highest snowfall totals: South of I-44 in Missouri and I-64 in Illinois, with 8 to 12 inches possible.
- Metro St. Louis: 2 to 4 inches along I-70, with more than 4 inches for the southern edge of the metro.
- Northern areas: 1 to 2 inches from Bowling Green, MO, to Jerseyville, IL, and Vandalia, IL.
Temperatures stay bitterly cold through Friday, meaning any snow that falls will stick. Expect tough travel conditions, especially southwest of St. Louis, where the highest totals are expected.
