Missouri wakes up under clear skies and biting cold air.
Breath hangs in the air, and frost grips windshields across the metro.
Temperatures sit near 26 degrees early, with calm winds offering little relief. Side streets and bridges feel dry, but shaded areas remain slick. Drivers should stay alert during the morning commute, especially near river crossings and elevated ramps.
A rapid warmup begins as the sun climbs. By afternoon, temperatures surge into the mid-50s, erasing the early freeze. It will feel more like March than February, and coats may come off quickly. This sharp temperature swing raises flash-freeze concerns later tonight where snowmelt or moisture lingers.
The warming trend accelerates Tuesday. Sunshine pushes highs into the low 60s, nearly 35 degrees warmer than this morning. Pavement dries fast, and outdoor plans get a green light. To be fair, this warmth comes with changing weather signals.
By Wednesday, conditions remain mostly sunny, with highs near 50 degrees. Clouds increase late, signaling a shift. Meteorologists are now tracking a midweek rain chance Thursday, with precipitation chances rising to 40 percent by nightfall. While wintry weather is not expected, damp roads could slow travel during the evening hours.
Friday stays mild but unsettled. Spotty rain chances linger, and clouds dominate. Temperatures hold in the mid-40s, well above seasonal norms for February.
Looking into the 6–10 day outlook, above-average temperatures continue across the Midwest. Signs point toward a sustained thaw, though winter is not finished. Each warm afternoon followed by colder nights increases the risk of refreezing on untreated roads.
