I'm not an expert in IR or computer vision by any means, so take this with a grain of salt. Air has such a low thermal mass that it doesn't measurably affect most IR sensors. Hot pavement could be a potential issue, but that shouldn't have a major effect on forward-facing sensors. Besides, it's only March. Even Arizona isn't that hot yet.
