Key Factors
- 01 Extreme Heat Warning in effect until 8PM EDT, heat index 100-110 - vehicle overheating and driver/passenger heat stress risk
- 02 High temperatures 93-97F from midday through early evening
- 03 Thunderstorm chances rising after 2pm (21% to ~50%), with storms likely 8pm-midnight (62-65%)
- 04 Storms could produce heavy rain, up to a quarter to half inch overnight, with possible ponding and reduced visibility
- 05 Code Orange air quality alert - unhealthy for sensitive groups
- 06 Winds are light (1-12 mph), so crosswind risk is minimal; no fog, ice, or freezing conditions expected
- 07 No visibility data provided, so storm-related visibility impacts are uncertain

Recommendation
Drive in the morning between 7:00am and 11:00am when conditions are dry and coolest, and in the evening aim for 6:00pm-8:00pm before storms become likely; avoid 2:00pm-5:00pm heat peak if possible and 8:00pm-midnight when thunderstorms with heavy rain are likely. Pre-cool the car, carry water, check coolant and tire pressure, never leave children or pets in the vehicle, and if caught in a downpour slow down and increase following distance.
