Key Factors
- 01 Sunny, dry conditions with only a 2–10% precipitation chance are forecast from 7 AM to 1 PM EDT.
- 02 Showers and thunderstorms may begin after 1 PM, with precipitation chances rising from 18% at 1 PM to 52% by 4 PM.
- 03 Thunderstorms are likely from 5–7 PM (64–65% chance) and again around 10–11 PM (63% chance); rain can reduce visibility and make roads slick.
- 04 Winds are generally 6–13 mph, with daytime gusts up to 23 mph; thunderstorms may bring rapidly changing conditions, though no separate severe-wind alert is provided.
- 05 Very hot conditions—high near 94°F and heat index near 95°F—may affect driver comfort and vehicle occupants, especially if stranded or without air conditioning.

Recommendation
Best morning driving window: 7 AM–12 PM EDT, before shower and thunderstorm chances increase. Safer evening window: no clearly dry evening window is forecast; if travel is necessary, use the comparatively lower-risk 7–8 PM EDT period, but check conditions immediately before leaving because thunderstorms remain possible. Avoid nonessential travel from 1–7 PM and again around 10–11 PM EDT; never drive through flooded roadway areas.
