(11:45AM - 6/20/19) A series of disturbances pushing through the region, along with a meandering frontal boundary, will bring the threat for repeated rounds of severe t'storms to the state Friday through Monday.
Friday morning-Friday night...
Several clusters of rain and t'storms are expected to move across much of the state Friday morning through Friday night. While much of the state will be impacted by this activity, of focus will be Central and Southern Illinois, in the vicinity of a warm front expected to be sitting across these areas. Near and south of the warm front, an environment in place featuring high instability, high moisture and good shear is expected. This will promote a widely scattered severe t'storm threat across a good portion of the state. Wind and hail will be the main threats. It is possible an upgrade in severe t'storm probabilities will be needed in future updates.
A severe t’storm threat will likely continue into Saturday-Monday as well for portions of the state. This will be discussed further in upcoming updates as the time approaches.
Below is our TAM severe t'storm forecast for Friday/night.
