​This Morning - This Evening, March 30th ~ Severe T'Storm Event:
​The main threat for an isolated to sporadic (levels 1-2) severe t'storm risk will exist across a large portion of Central and Southern Illinois, this morning through this evening. A broken line of rain and t'storms that developed Tuesday afternoon and evening across portions of Kansas, Missouri, Oklahoma and Texas tracked northeastward last night. This activity is now pushing into western portions of the state this morning. This activity will continue to spread northeastward across much of the state, this morning through this evening. The environment expected to be in place ahead of this activity as it pushes across the state, will be favorable for some severe t'storm threat across portions of the state. The environment that will be in place will feature very low instability of 100-1,000J/KG, dew points in the mid 50's to near 60, good shear, good forcing, and mediocre lapse rates of 4.0-6.5C. This environment will be supportive of upwards of an isolated to sporadic (levels 1-2) severe t'storm risk across a large portion of Central and Southern Illinois. Damaging winds and isolated tornadoes will be the severe weather threats.

As the storm system organizes and strengthens as it moves through the region today, a period of high winds are expected across portions of the state this morning through this evening. High winds aloft, characterized by a low level jet (850MB) of upwards to 50-75KT and 925MB winds of 35-60KT, will be in place. Adequate mixing is anticipated at least up to 900MB, which will aide in transporting higher winds to the surface. During this period, southerly wind gusts of upwards of 35-50MPH to 45-60MPH are expected across a a large portion of Central and Southern Illinois, this morning through this evening.
