Stationary front is draped across the middle of the country which turns to a cold front in the Northeast region.. This front will be the focus of severe weather potential.
Tornado potential will be where the EHI is above 1 this will be Kansas, Nebraska,Eastern and Southern South Dakota, Southern Minnesota, Iowa , Northern Illinois, Southwestern Wisconsin, Northern Missouri.. With the EHI that high we are going to issue a 10% chance of tornadic activity in that region..
Outside of the above mentioned area will be the potential for Damaging Winds and Hail..
