It continues to be warm in the central part of the country. The Climate Prediction Center outlook for the next 6-10 days continues that trend:

Of course, with cooler weather also comes the rain--the same troughing that ushers in cooler temperatures also brings that colder air closer to the very warm air sitting to the south. The tightening of the temperature gradient there promotes stronger winds aloft and more convergence at the surface. Both of these ingredients contribute to increased chances of storms. Therefore, the CPC's 6-10 day precipitation forecast shows a similar pattern:
