Recommendation
Drive in the early morning (7AM-9AM) before peak heat sets in, and again in the early evening (6PM-7PM) after temperatures start dropping, but watch for isolated thunderstorms between 4PM-9PM - reduce speed and increase following distance if storms develop. Ensure vehicle cooling systems and tire pressure are checked given extreme heat.
