ST. LOUIS, MO (KTVI) - A couple of rounds of showers and thunderstorms will hit St. Louis Tuesday afternoon and evening. Many of these storms will be severe.  A Severe Thunderstorm Watch is in effect for the bi-state until 7:00 P.M.

Storms are likely to develop Tuesday evening as the air becomes very unstable, especially along and south of I-70.  The fairly high instability will lead to some pretty hefty thunderstorms developing in clumps, also along an advancing cold front. The main threats will be damaging winds and large hail south of the warm front. However, conditions near the front will be more favorable for possible isolated tornadoes with any storm that is on or very near that front. That will need to be watch closely.

Timing:

This first round of storms will move in Tuesday afternoon.  There should be a brief lull in activity before more intense storms bubble up and spread east across the area into the evening.

In this type of pattern, it is tough to say when a storm may hit in any one location.  I can say that scattered storms will be around pretty much the rest of the day, with an increase in coverage from west to east through the afternoon.
