FINALLY! A sizeable cooldown, even if it is only here for a day or two. After the mid-to-upper 100's on the High Plains on Sunday, we'd do anything for cooler weather. This front is going to test those theories.

The same parent system that brought the extremely critical fire weather to the Pacific Northwest has pushed into southern Canada. That will help rifle through our latest thought of Fall. However, because there is so much wind energy with this system, wind shear is going to be easy to come by, meaning any storms that get going could become organized quickly.
Storms look like they might struggle to get going in the afternoon, pushing the window back into the early overnight hours. That would favor damaging winds and large hail as the primary threats to watch out for.
Another threat to keep an eye on is the flooding threat. This front isn't going to be in a hurry, so as it walks southward, it will focus a few rounds of storms somewhere. Right now, that looks to take aim at Iowa and northern Missouri.
As the front drops south, the severe threat will follow it. On Wednesday, a MARGINAL threat for severe storms stretches from eastern Kansas to central Illinois.
SMOKY AGAIN?!This won't be quite as bad as our last dose of wildfire smoke when southern Canada was on fire. This time it's the Pacific Northwest sending a healthy helping of hazy skies to the plains. But it's the front that's driving it southward. In fact, you probably noticed a bit of a haze already. The smoke that could affect anyone with sensitive respiratory systems will be along and behind the front today.
