Key Factors
- 01 Extreme Heat Warning in effect until 8:00 PM EDT; impacts include heat illness risk and no effective overnight cooling (lows in the low to mid 70s).
- 02 Temperatures climb from the upper 80s to 103–104°F late afternoon/early evening, with heat index values as high as 110°F (daily forecast).
- 03 Higher near-100°F conditions coincide with typical commute times (roughly 10:00 AM–7:00 PM), when heat stress can be greatest for people in or out of vehicles.
- 04 No precipitation is expected (0% hourly), so the main hazard is heat rather than road slipperiness or reduced visibility.
- 05 Wind is light to moderate (3–9 mph from the west), so no major weather-related visibility or crosswind hazard is indicated; heat remains the dominant risk.

Recommendation
Safer driving window: 7:00–9:00 AM EDT (temperatures ~79–82°F). Avoid travel during the peak heat hours; if you must drive, reduce exposure and take breaks in air conditioning. Evening window: 7:00–8:30 PM EDT (temperatures ~99→96°F, still hot but starting to ease as the day cools).
