A storm system coming out of the Pacific Northwest will target the midwestern states mentioned above … over the day you will have passing activity, but as the upper divergence comes into the area, increasing southerly winds at the surface will develop along a front coming out of the north.

This will mark a strong tornadic summer to come, forecast coming soon …
