Missouri greets the morning with dry pavement, pale winter sun, and a chill that hints at sharper cold ahead. The quiet start won’t last. Temperatures fall steadily, and winter conditions become more disruptive as the week pushes toward the weekend.
According to the National Weather Service in St. Louis, today turns brighter after early clouds, with highs reaching the low 40s. Winds remain breezy, and colder air continues filtering in. Tonight drops into the upper 20s, allowing refreezing on shaded roads and sidewalks.
Thursday stays dry but colder. Afternoon highs hover near the upper 30s, offering little melt. By Thursday night, temperatures fall into the low teens, tightening the grip of winter across the metro area.
Friday brings the coldest air so far. Highs struggle to reach the mid-teens, and brisk winds push wind chills into the single digits. Roads remain dry, but any leftover moisture may refreeze quickly after sunset.
Snow chances increase Friday night into Saturday. Light snow is possible, with the highest chances developing through the day Saturday. Accumulations look limited, but even minor snowfall could create slick travel conditions. Bridges, ramps, and untreated streets may turn icy as temperatures stay below freezing.
Saturday afternoon highs remain near the mid-teens, preventing much melting. Saturday night drops near 10 degrees, raising flash-freeze concerns wherever snow compacts or briefly melts earlier.
Sunday trends calmer but still cold. Partial sunshine returns, with highs near the low 20s. Cold air lingers into early next week.
Looking ahead, the 6–10 day outlook keeps Missouri colder than normal, with additional chances for snow returning as active winter patterns continue across the Midwest.
