It will fog it, the number I've heard is 120 F and beyond, which is easy to achieve there.

I avoid getting my film any warmer than 90 or so. Keeping the film and it's container out of the sun helps, park in the shade whenever possible.
If you can, don't leave the film in the car, but take it with you. Using the trunk instead of the passenger compartment might be better, as you avoid the solar heating effect. Beyond that, you'll need to use a cooler and maintain it with ice or a substitute.
