Missouri and western Illinois wake up under thick clouds and damp pavement as steady February rain moves across the St. Louis metro. Temperatures hover near 45 degrees at Lambert Airport, and light south winds keep the air cool but not bitter.
Rain increases through mid-morning, with a 100 percent chance of wet weather lasting into the afternoon. Streets along I-64, I-44, and I-55 will stay slick. Allow extra braking distance and watch for ponding in low spots.
To be fair, this is not a winter storm. No snow or ice is expected today. Still, steady rainfall could briefly reduce visibility during heavier bursts. Keep umbrellas handy if heading out before lunchtime.
Rain continues into the evening before tapering late. Lows settle near 45 under cloudy skies. By Sunday, a weak system pulls east. A slight chance of early rain lingers before clouds gradually break. Highs rebound to near 58 degrees as sunshine increases late day.
President’s Day Monday looks mild and bright. Mostly sunny skies push highs to around 63 degrees, well above mid-February averages. That warming trend continues Tuesday with highs near 68 and mostly cloudy skies.
Midweek turns even warmer. Wednesday reaches near 71 degrees under partly sunny skies. A small rain chance returns Thursday, but temperatures stay elevated. The broader 6–10 day outlook favors above-normal warmth across Missouri and Illinois, signaling early Spring Vibes through much of next week.
Five Day Outlook for St. Louis, Missouri:
Sunday: Slight early rain, then mostly sunny, high 58.
Monday (President’s Day): Mostly sunny, high 63.
