St. Louis Weather: Summer Heat Gives Way to Storms
17 Apr
Summary
- Temperatures feel like summer, but scattered storms with hail are arriving.
- Strongest storms tonight may bring pea-sized hail and 45 mph wind gusts.
- A cold front Saturday will cause temperatures to drop significantly.

Mid-April in St. Louis is currently mimicking early summer conditions, with temperatures pushing into June-like territory. However, this warm spell is short-lived as scattered thunderstorms are expected this evening and overnight.
These storms could bring pea-sized hail and wind gusts up to 45 mph, primarily affecting travel due to short, intense bursts of rain. The immediate concern is not prolonged flooding but the potential for brief travel disruptions from these convective cells.
Friday will continue the warmth with windy conditions and highs climbing into the mid to upper 80s. This unsettled air mass highlights the atmosphere's capacity for rapid changes. The st louis weather radar will be crucial for tracking storm development and organization.
The weekend marks a significant turning point. A cold front arriving Saturday will bring more thunderstorms and a noticeable temperature drop, with highs forecast to be in the 60s. This is a substantial shift from Friday's warmth.
By Sunday morning, some areas may see temperatures in the upper 30s and lower 40s, reflecting the dynamic nature of spring weather. Residents should adjust plans accordingly, as Friday's warmth will be replaced by cooler, unsettled air.
