Missouri starts the morning calm and cool, but a dramatic February warm-up is already underway. Skies remain mostly clear before sunrise across St. Louis. Temperatures sit in the mid-40s early, but they won’t stay there long.
Sunshine builds quickly this morning. Highs surge to the mid-60s by afternoon. Light south winds increase slightly, signaling a stronger push of warm air. It feels more like late March than mid-February.
Tuesday keeps the Spring Vibes rolling. Clouds increase, but highs still reach the mid-60s. A few spotty showers could develop late Tuesday night. Winds gust near 30 mph at times, adding a breezy feel.
By Wednesday, February 18, sunshine returns and temperatures climb again. Highs push into the lower 70s. That’s nearly 20 degrees above average. The warm stretch continues into Thursday with another high near 73 degrees.
However, a shift arrives late Thursday. Showers and possibly a rumble of thunder move in during the afternoon. Rain chances continue into early Friday. No Snow or Ice Storm concerns are expected, but wet roads could slow travel during heavier bursts.
Looking ahead into President’s Day Week and the 6–10 day outlook, temperatures trend cooler but remain seasonable. Highs ease back into the 40s and 50s by the weekend. A brief Thaw dominates now, but winter isn’t completely finished.
For now, St. Louis enjoys a rare February warm spell. Keep the jacket handy for cool mornings, but plan for afternoons that feel almost springlike across Missouri.
