St. Louis, Missouri – Missouri and Illinois are expected to settle into a near-normal temperature pattern during the first full week of February, marking a transition away from western warmth and toward more typical midwinter conditions across the central Midwest.
According to the National Weather Service and NOAA’s Climate Prediction Center, temperatures from Tuesday through the following Monday are favored to run close to seasonal averages across both states. This places the Missouri–Illinois corridor between stronger warmth to the west and colder-than-normal air farther east, resulting in a more balanced and stable setup.
Across Missouri, including Kansas City, Columbia, and St. Louis, daytime highs are expected to range mainly through the 30s, with overnight lows dropping into the teens and 20s. Illinois follows a similar pattern, with cities such as Springfield, Peoria, and Chicago holding near early February norms. Southern Illinois may see occasional slightly milder afternoons, but no sustained warm-up is indicated.
This near-normal stretch suggests fewer extreme temperature swings compared to recent weeks. Freezing nights will remain common, limiting snowmelt and keeping winter hazards in place, but without prolonged Arctic cold.
Precipitation chances appear limited overall, reducing the likelihood of widespread snow or ice. Travel along major routes such as I-70, I-55, I-64, and I-80 should remain manageable, though refreezing overnight may still lead to slick spots during early morning hours.
For residents, this period represents a return to familiar February conditions rather than a push toward spring or severe cold. While winter remains firmly in control, the quieter pattern may offer some consistency heading deeper into the month. Additional outlook updates are expected as broader weather trends continue to evolve.
