St. Louis, MO – Warm fall sunshine in the St. Louis metro will give way to showers and possible thunderstorms by Saturday morning, ending the week with slick roads and soggy yards. Commuters and weekend travelers along I-70, I-64, and I-55 should be alert for slower traffic and reduced visibility during the first half of the weekend.
Warmer End to the Week
According to the National Weather Service in St. Louis, highs will remain in the mid-80s through Friday, providing a warm, sunny finish to the week. However, a cold front from the Plains will sweep in on Friday night, bringing scattered showers and a few rumbles of thunder. The front is expected to arrive with a 70% chance of rain for the bi-state metro area, impacting not only evening plans but also outdoor activities for those with early Saturday commitments. Though severe weather is not expected, brief heavy rain may cause disruptions, particularly for morning soccer games, farmers markets, and outdoor festivals.
Saturday Storms and Cooler Conditions
By Saturday morning, the rain will begin to taper off, leaving behind cooler temperatures and windy conditions. The high will only reach the upper 70s, which marks a noticeable drop from Friday’s warm temperatures. However, by late afternoon, clear skies will return as the front moves eastward, making way for a crisp and breezy evening. The cooler air will dominate, bringing fall-like conditions to the region, with winds picking up and temperatures falling into the low 50s overnight.
Sunday Brings Crisp Fall Air
As the weekend progresses, Sunday will bring sunny skies and cooler temperatures, perfect for outdoor fall activities. Highs will reach a comfortable 68°F, making it ideal for pumpkin patch visits, park outings, and fall decorating. The sunshine will be accompanied by crisp, cool air, signaling a return to more typical fall weather for Missouri and Illinois.
Clear Skies for the Week Ahead
Looking ahead to early next week, the weather will stay dry and mild, making it perfect for Halloween setups and leaf-peeping plans. The mild conditions will be a welcome reprieve from the cooler air expected over the weekend, and early forecasts show temperatures remaining in the 60s and 70s for Monday and Tuesday.
Travel Advisory and Precautions
Residents are advised to secure decorations and check local event updates before heading out on Saturday morning. As wet conditions are expected to impact early Saturday, travelers should allow extra time to reach their destinations, especially in areas prone to flooding. Drivers should also be cautious near flooded low spots, particularly along Metro East roadways and near river crossings, where water levels could rise following heavy rains.
