ST. LOUIS, MO (KTVI) – Thunderstorm chances will increase as we go into late afternoon and especially early this evening. The air over the bi-state area is becoming quite unstable as a slow moving cold front drifts southward into the region.
Conditions are favorable for several clusters of strong storms in our area with a couple of them possibly becoming severe with large hail and stronger wind gusts. Not everyone will get the big hail, nor will they see damaging winds but a few spots are severe weather are certainly possible.
There will be a greater risk of more substantial winds and hail east of STL into southeastern IL and extending east into southern Indiana. In our viewing area, the risk appears to increase as you hit I-57 and points east.
As for timing, there could be a renegade storm or two try and popup early this afternoon, but the more likely timing is after 4pm with peak activity between 5pm and 9pm.
Again, there is a risk of some stronger storms pretty much everywhere…but the most severe storms are most likely east of Saint Louis.
