(11:15AM - 3/24/19) A storm system pushing through the region has spread areas of rain and t’storms across the state this morning. This activity is likely to continue in periods into tonight across the state. A severe t’storm threat will also exist across Southern Illinois this afternoon and evening.
A warm front is pushing northward across Southern Illinois this morning and afternoon. South of this front an environment featuring low instability, modest moisture and modest shear will exist. As the low pressure and associated cold front approach the state during the afternoon, scattered t’storms will develop across Eastern Missouri into Southwest Illinois by mid-afternoon today. This activity will then push across much of Southern Illinois during the rest of the afternoon and evening. Given the environment in place, an isolated to widely scattered severe t’storm is possible, with the best chance being near and south of I-64 in Southern Illinois. All modes of severe weather are possible with any severe t’storm.
