Are there parts of the country where thunderstorms occur only at night?

Thunderstorms tend to develop at certain times of day, depending on geography, but we haven't heard of a place where storms are exclusive to a particular time. The southeastern United States seems to have most of its thunderstorms in the middle of the night, and Kansas City, Missouri, and Minneapolis get more thunderstorms at 2:00 A.M. than at any other time of day. The flat landscape, and its effect on the sky, is largely responsible for this nighttime phenomenon. In the high plains from Montana to Texas, the cool fronts that often form in late spring and summer are responsible for afternoon and evening thunderstorms when they meet up with hot, humid air coming off the plains. These storms roll east into the late evening.
