Recommendation
Safe to drive today; no weather-related travel restrictions. Best morning window is roughly 7:00-10:00 AM (74-85F) and best evening window is after 8:00 PM (falling to mid-80s and cooler). Avoid long trips 1:00-6:00 PM when heat peaks near 97F; carry water, check tire pressure and coolant, never leave people or pets in a parked car, and use sunglasses for glare.
