St. Louis, MO – A mild and comfortable stretch is moving across Missouri today as temperatures rise well above typical mid-November levels. But forecasters say the warmup will be short-lived, with a Monday rain shift signaling the start of a cooler, unsettled pattern heading into Thanksgiving week.
Weekend Warmup Across St. Louis
Residents across the St. Louis metro are waking up to a calm, glowing morning along the Mississippi River, with thin clouds and dry pavement offering a quiet start to Saturday. Weather experts say this peaceful setup marks the beginning of a two-day warm trend before conditions change again early next week.
Highs today and Sunday are expected to climb into the upper 70s, with some southern suburbs reaching 80 degrees, making this one of the warmest stretches of November so far.
The warm air, combined with breezy southwest winds, will make outdoor conditions ideal for yard cleanup, early holiday decorating, and pre-travel preparations. Drivers should be alert for gusty winds on elevated roadways, especially along I-55 and I-64 later today.
A Weather Shift Begins Late Sunday Night
Skies remain partly to mostly sunny through Saturday, but changes begin to build Sunday evening as moisture lifts into the region. Clouds will increase, signaling the arrival of a cooler and more unsettled Monday.
Meteorologists say temperatures will remain too warm for snow or ice, but the shift from warm air to a cooler pattern could happen quickly by late Monday and into Monday night.
Monday Rain Chance and Cooler Trend
Rain chances develop after midday Monday, bringing the first sign of a broader pattern change moving into the Midwest. Temperatures will fall into the 40s Monday night, offering an early hint of a colder setup heading into Thanksgiving week.
Forecast models are now tracking multiple disturbances next week, including a potentially stronger storm system that could impact regional pre-holiday travel.
Broader Weather Pattern for Thanksgiving Week
Forecasters say next week may bring several waves of cooler, cloudy, and rainy conditions. While no winter precipitation is expected at this time, the pattern is trending more active and could complicate travel for those heading out early for Thanksgiving.
Temperatures will gradually step down through the week, with highs mostly in the upper 50s to low 60s and periodic rain chances continuing.
