Strong Storms Could Accompany Heavy Rain Wednesday

In the previous post you read about the potential for heavy rain to occur on Wednesday, but some signs are coming together that are pointing to the threat for strong to severe storms in the afternoon.

An incoming warm front will lift north into the Midwest and bring with it a warmer and unstable air mass. Dew points will rise into the mid and upper 60s across northern Illinois, while dew points west make it into the upper 60's and low 70's.

There are a lot of variables though that will come into play that will effect what type of storm coverage we'll have. The timing of the 'mini-low' in conjunction with the warm front, along with outflow boundaries(mini cool fronts) from previous storms will with both have an effect on where storms develop through the afternoon. If strong storms do develop, the primary threats would be strong straight line winds and hail, though an isolated tornado can't be ruled out in Iowa or southwest Wisconsin. Another round of storms with heavy rain is looking more likely again on Friday, along with the potential for strong storms too. Thursday will be relatively dry, but more humid and warmer!

We'll continue to keep an eye on this system, but until then go out and enjoy the beauty two days we have on tap!
