That is one hot land mass.
There is a hot air system coming up from central Mexico and the southern border of Mexico where it meets with the Pacific Ocean. The thing is this, the variations in the temperature migrating north are enough to cause concern for increased turbulence along that air insertion coming north.

The increased water vapor accumulations are accommodated by the higher elevations in Colorado with it reaching down to New Mexico, but, further east the Great Lakes are providing evaporation as the heated air reaches those higher latitudes. Additionally, with the sun going down the upper air mass will cool faster than the air next to the ground. It is a concern. The greatest moisture accumulation has occurred in the past hour.

The movment toward turbulence began between these two satellite images. I hope it is nothing but some rain perhaps. The mid-latitude vortex off the west coast is facilitating the movement of air from the south to the north and making room for more water vapor accumulation as it builds in velocity.
