St. Louis woke up to clear skies on Wednesday, April 29, with temperatures in the low 50s and a quick warm-up already in the cards. Sunshine will own the day, with a high near 67°F, although a brisk northwest breeze will keep it feeling a bit cooler than the thermometer suggests. The rest of the workweek looks mostly dry, with only a brief, low chance shower window late Thursday night into early Friday.
Afternoon Winds Pick Up
By this afternoon, northwest winds will run 8 to 12 mph, with gusts up to about 21 mph that could rattle unsecured patio umbrellas and make riverfront conditions feel extra blustery. According to the National Weather Service, highs should top out near 67°F on Wednesday, and winds will ease after sunset. If you have outdoor plans, it is a good idea to secure lightweight items and dress in layers to handle the breeze.
Small Rain Chance Late Thursday Night
A weak frontal boundary could throw a few spotty showers into the area after 1 a.m. Friday, May 1, but measurable rain is unlikely and most places will stay dry. Friday will run a touch cooler, with a high near 63°F as cooler air filters in behind the front. Expect mostly dry conditions through Saturday before a modest warm-up returns Sunday and continues into next week.
Weekend Frost Watch For Some Suburbs
Cooler nights will bring a late-season frost risk for some outlying areas Saturday morning, May 2, especially north of I-44 in Missouri and north of I-70 in Illinois. The National Weather Service notes that probabilities for lows below 37°F peak in those zones, so suburban gardeners may want to cover tender plants. Most urban neighborhoods should stay above freezing and simply wake up to a chilly start to the weekend.
What To Know
Expect a sunny and breezy Wednesday with a high near 67°F, and plan to secure loose outdoor items as gusty northwest winds continue into the late afternoon. A slight, spotty shower threat arrives late Thursday night into early Friday, and early May frost is possible in some northern suburbs on Saturday morning. Temperatures rebound on Sunday, with highs climbing back into the 70s by Monday.
