In-Depth Analysis

The St. Louis region and Missouri face a heightened risk of heavy rainfall and potential flooding this week. According to multiple weather sources, including the National Weather Service and local news outlets, scattered downpours are expected, elevating the possibility of localized flooding.

On Tuesday, July 8, the 5 On Your Side Weather Impact team issued a Weather Impact Alert from 1 p.m. to 8 p.m., noting a marginal risk of severe weather. This includes the potential for winds between 50 to 70 mph and small hail. The primary concern is heavy rainfall, which could lead to nuisance flooding in areas struck by multiple rain cells.

Looking ahead to Friday, July 11, the northern half of Missouri is also at risk of heavy rainfall. Meteorologists indicate that rainfall could exceed flash flood levels within 25 miles of affected areas. There is also a potential for higher rainfall over the Ozarks, which could lead to significant convergence and temporally extend rainfall.

Ryan Hall Y'all noted high dew points over Missouri later this week, indicating substantial moisture in the atmosphere, which further increases the likelihood of heavy rainfall.

**How to Prepare:**

  • Stay informed about the latest weather updates from reliable sources such as the National Weather Service and local news.

  • Ensure that you have a plan in place in case of flooding, including an emergency kit.

**Who This Affects Most:**
