Missouri greets the morning with stiff winds, numb fingers, and frost-coated rooftops across the St. Louis metro. The air feels sharp, and exposed skin cools fast before sunrise.
Temperatures hover in the mid-20s early, with wind chills in the teens. This cold snap is brief but impactful. Drivers should watch bridges and overpasses for isolated slick spots early. Leave extra braking distance and let vehicles warm gradually.
Sunshine quickly changes the feel today. By afternoon, readings climb toward the upper 30s. Winds ease slightly, improving comfort for errands and commutes. Winter still holds the morning, but its grip loosens by midday.
Saturday marks a noticeable shift. Highs surge into the mid-50s under mostly sunny skies. It will feel almost springlike compared to today. Layers become optional by afternoon, and outdoor plans look favorable. Roads stay dry, supporting smooth regional travel.
Saturday night cools back near freezing. Patchy frost may return in sheltered areas. Early drivers Sunday should stay alert, especially outside the urban core.
Sunday remains mild and quiet. Sunshine dominates with highs in the low 40s. This stable pattern supports easy highway travel and last-minute holiday shopping. Winds stay light, and visibility remains clear.
Looking ahead to Christmas travel week, the warm trend strengthens. Monday reaches the upper 40s, then temperatures jump dramatically. By midweek, highs push into the 60s and even near 70 by Christmas Day. That warmth raises an early winter call-out: wet roads at night could refreeze if colder air returns later. For now, no snow or ice signals appear.
This stretch highlights classic December temperature whiplash. Keep coats handy in the mornings, but plan lighter gear by afternoon. Traveling this weekend or early next week? How big did the temperature swing feel in your neighborhood?
