Get ready for a winter weather event like no other in the St. Louis region this week, with two systems bringing snow and potential travel disruptions.
The St. Louis metropolitan area is expected to experience two winter weather systems this week, with the second system on Wednesday potentially causing significant travel disruptions across the region.
The First Storm Monday Night: Less Than 1 Inch of Snow Expected, The first round of snow is expected to hit the area on Monday night into early Tuesday morning, with less than an inch of precipitation forecasted. Southern counties could see slightly higher totals up to two inches, with minor travel impacts expected primarily on bridges and overpasses.
Brief Clearing on Tuesday, Then Significant Weather Event Wednesday, There should be a brief clearing between systems on Tuesday, with only occasional flurries or drizzle possible before Wednesday’s more significant weather event arrives. Wednesday’s system presents a more complex weather pattern, with snow expected to begin after the morning commute.
St. Louis, Missouri experiences a humid continental climate with hot summers and cold winters.
The average high temperature in July is around 90°F (32°C), while the average low temperature in January is approximately 24°F (-4°C).
Precipitation is evenly distributed throughout the year, with an average annual rainfall of 41 inches (1,041 mm).

Extreme weather events, such as thunderstorms and heavy snowfall, can occur during the spring and winter months.
Transition from Snow to Rain/Snow Mix and Back to Snow in Evening Hours, The metro area may experience a transition from light to moderate snow to a rain/snow mix before returning to snow in the evening hours. Areas northwest of St. Louis are forecast to receive all snow, while regions to the south and southeast can expect more of a wintry mix.
Snow weather, also known as snowfall or winter precipitation, occurs when atmospheric moisture freezes into ice crystals in the atmosphere.
This process typically happens when warm air rises and cools, causing the water vapor to condense into droplets that freeze into ice crystals.
According to the National Weather Service, snowfall is most common in areas near 30-50°N latitude, including northern Europe, Asia, and North America.
Challenging Travel Conditions Expected on Wednesday, Officials anticipate this second system will create more challenging travel conditions than the earlier event. Check FOX 2’s traffic map for real-time updates and download our app for weather alerts.
