Key Factors
- 01 Heat Advisory until 8 PM EDT with heat index up to 93-95F, increasing risk of vehicle/driver heat stress (engine, tires, dehydration)
- 02 Showers and thunderstorms become likely from early afternoon onward: PoP rises to 40% by 3 PM, 52% by 4 PM, and 64-65% from 5-6 PM
- 03 Wind gusts as high as 23 mph during the day can create crosswind and debris hazards near storms
- 04 Thunderstorms can bring sudden heavy downpours, reduced visibility, and slick roads, especially late afternoon and evening
- 05 Visibility data not provided, so storm-related visibility impacts are uncertain

Recommendation
Drive in the morning between 7 AM and 11 AM when conditions are sunny and dry with low precipitation chance (about 2%). For evening travel, the safest window is after roughly 7 PM (PoP drops to ~34% around 7-8 PM), though scattered storms remain possible; avoid driving during the 3 PM to 7 PM peak storm window if you can. Stay hydrated, use headlights and increase following distance in rain, and slow down for ponding water.
