St. Louis is trading late-summer warmth for a blustery fall reset Friday: mostly cloudy skies, a high near 55, and northwest winds around 17 mph with gusts up to 33 mph. A few rain showers could move through after 3 p.m., but the chance of precipitation is only 20%.
Windy, Cool Friday Ahead
The National Weather Service expects clouds to thicken through the afternoon as temperatures hold in the low to mid-50s. The wind will be the bigger factor for outdoor plans, making Friday feel colder than the thermometer suggests.
Temperatures will fall to around 41 Friday night as north winds ease to between 8 and 16 mph. A Frost Advisory is in effect from 1 to 9 a.m. Saturday across portions of northeastern Missouri and west-central Illinois, although the St. Louis forecast calls for a somewhat milder low.
Sunshine Returns Saturday
Saturday brings sunny skies, lighter winds and a high near 60, followed by a clear night with temperatures dipping to around 38. Sunday should be brighter and milder, reaching about 66 degrees with light, variable winds.
Warmup Builds Into Next Week
The forecast turns mostly dry Monday through Thursday, with highs around 71 Monday, 75 Tuesday, in the low to mid-70s Wednesday and 83 Thursday. Overnight lows remain comfortably cool in the 40s and low 50s.
For Friday plans, the main concern is wind rather than a washout, so layers will be more useful than a heavy rain jacket. Weekend outdoor plans look considerably friendlier once the clouds and gusts move out.
