(11:30AM - 4/8/20) Multiple disturbances moving through the region into tonight will continue to bring the change for severe t'storms to the state.
This morning - tonight...
Areas of showers and isolated t'storms have been ongoing this morning across portions of Iowa, Minnesota and Wisconsin, associated with the next disturbance moving through the region. The main focus will be this afternoon into tonight... Scattered showers and t'storms are expected to develop this afternoon, in the vicinity of a advancing cold front, from Iowa down into Missouri. This activity will then spread eastward across Central and Southern Illinois, from this afternoon into tonight. An environment featuring low to moderate instability, decent moisture, good forcing and good shear will be in place. This will help support a limited to elevated severe t'storm threat across much of Central and Southern Illinois. Large hail and damaging winds will be the main threats, though an isolated tornado cannot be ruled out. Significant/very large hail (possibly upward of 2-3" hen egg-baseball size) is a high possibility.
Below is the severe t'storm forecast for this morning - tonight.
