Key Factors
- 01 Extreme Heat Warning until 8 PM EDT: heat index 100-110, with temperatures peaking near 96-97F from 2-5 PM
- 02 Thunderstorm chances rise from 21% at 2 PM to 44-50% by 5-8 PM and 62-65% at 8-11 PM, with possible heavy rain reducing visibility and causing hydroplaning
- 03 Air Quality Alert (code orange) may affect sensitive groups
- 04 Risk of vehicle overheating, tire stress, and lethal car interior temperatures for children and pets
- 05 Winds are light (1-12 mph), so crosswinds are not a concern; no visibility or fog data provided, and rainfall totals are uncertain (less than 0.1 in daytime, 0.25-0.5 in overnight)

Recommendation
Safest windows: morning 7:00-10:00 AM (77-84F, sunny, precipitation chance under 5%) and early evening around 6:00-7:30 PM only if radar is clear, since storm chances increase afterward. Avoid driving 2-5 PM for peak heat and 8-11 PM for likely thunderstorms. Carry water, use A/C, check coolant and tire pressure, never leave children or pets in the car, and slow down or pull over in heavy rain.
