Key Factors
- 01 Extreme Heat Warning in effect until 8 PM EDT with heat index 100-110°F increases driver fatigue and heat exhaustion risk
- 02 Thunderstorm probability increases from 21% at 2 PM to 65% by 10 PM, with heavy rain possible
- 03 Rapid temperature swing from 96°F at 4 PM to 77°F by midnight indicates strong storm development
- 04 Air Quality Alert (Code Orange) may affect visibility and respiratory function during outdoor driving
- 05 Wind shifts from NW (8-12 mph) to W (variable 1-10 mph) as storms approach, reducing crosswind hazard but increasing instability

Recommendation
Safest morning window: 7 AM to 10 AM EDT when temperatures range 77-88°F, humidity is manageable, and no precipitation is expected. Safest evening window: After 9 PM EDT once storms are winding down and conditions stabilize. Avoid driving between 2 PM and 8 PM EDT due to peak heat index values and rising thunderstorm probability. If driving is unavoidable, ensure vehicle air conditioning is functional and stay alert for sudden weather changes.
