More than 72 million Americans are expected to travel for the Fourth of July holiday. Some may be in for a rainy trip.

The hottest spots should include portions of the Midwest, South and Southwest. Readings top out in the 90s and 100s in those locations.

We've jumpstarted our summery weather after a cool and rainy May and June. The week leading up to the holiday features hot, humid, and occasionally stormy weather, especially on Thursday with an associated cold front.
