ST. LOUIS — The threat of severe thunderstorms ended for the 5 On Your Side area this Tuesday evening. Breezy conditions continue into Wednesday.
---
As the first major line of storms slides by the St. Louis area, dry air limited how severe storms could be in the region.
The National Weather Service could cancel the Severe Thunderstorm Watch before 9 p.m. The watch was initially issued for the entire St. Louis and Metro east region.
The NWS also issued a Tornado Watch for Pike County until 8 p.m., which will likely continue because there is a chance a rogue storm may pass through northwest Missouri counties Tuesday evening.

The stage was set for potential severe storms when springtime warmth surged back into St. Louis over the past weekend.
High temperatures reached 89 degrees at St. Louis Lambert on Sunday afternoon. Expect an uptick in humidity on Monday and Tuesday to produce a few thunderstorms. Along with the warmth ahead of this system, moisture will be drawn north from the Gulf of Mexico. Expect moisture-rich air as this weather system moves into our region on Tuesday.
The Storm Prediction Center highlights a good portion of the Mississippi River Valley for the potential of strong to severe thunderstorms.
