Missouri – Cold air bites early across eastern Missouri as pale sunlight reflects off frozen pavement and bare trees. Breath hangs in the air, and the Mississippi River corridor sits under a quiet but watchful winter sky.
According to the National Weather Service in St. Louis, there is a 40 percent chance of light snow developing later today, mainly during the afternoon and early evening. Any accumulation is expected to stay under a quarter inch, but even small amounts could create slick spots on bridges and elevated roadways, especially near I-70, I-64, and I-55.
Morning temperatures started near 2 degrees, with wind chills well below zero in exposed areas. Highs struggle to reach the upper 20s this afternoon. Snow chances remain focused east of the Mississippi River, including parts of southwest Illinois, though flurries could drift into the St. Louis metro.
Drivers should remain cautious late today. Even brief snow showers can reduce visibility and quickly coat untreated roads. Flash freezing becomes a concern after sunset as temperatures fall back into the teens.
Conditions calm heading into Monday. Sunshine returns, and highs climb to around 37 degrees, offering a short break from the deep chill. Clouds increase Monday night, but dry weather holds through midweek.
By Tuesday and Wednesday, temperatures stay seasonably cold, with highs in the low to mid-30s. No hazardous weather is expected beyond today, though winter remains firmly in control across the region.
Looking ahead toward the first full week of February, longer-range outlooks suggest below-normal temperatures across much of the Midwest, with limited precipitation. The frozen Great Lakes continue to reinforce cold air patterns, keeping winter locked in.
