Thursday Storm Potential

We're still watching the potential for strong storms this evening, with a slight risk in place over the Stateline, and an enhanced risk of severe storms over central Wisconsin.

There is still potential for storms to develop this afternoon with any extra energy waves that move through, these storms have the potential to produce heavy rain and even some hail.

The higher threat for strong storms will be overnight into early tomorrow morning. We'll watch for storm development over central Wisconsin this afternoon, but then they will head southeast through the evening. Storms will develop ahead of a cold front, with very hot and humid air in place.

The main triggers for storms will be the cold front and incoming mid-level disturbance. There are high levels of CAPE and moderate levels of shear in place which could fuel storms. Though, the timing is not the most favorable for severe weather, once the sun sets.

 Models have had a hard time with how and if these storms hold together over the Stateline. One model, the HRRR, does keep the strong storms in place as they move over the Stateline.The cold front passes early Friday morning which will end the threat for any rain. It will also be a lot less humid Friday afternoon.
