Key Factors
- 01 Extreme Heat Warning is in effect until 8:00 PM EDT (heat index 100–110), increasing risk of heat illness and making car interiors dangerously hot if you’re delayed.
- 02 Isolated showers and thunderstorms are forecast to begin after about 4:00 PM with increasing chances during the evening (hourly PoP rising to ~20–24%).
- 03 Thunderstorms can bring sudden downpours, slick roads, and reduced visibility/traction, especially in the evening hours.
- 04 Wind speeds increase into the afternoon (about 9–10 mph), but no gust or visibility data is provided, so crosswind/visibility impacts are uncertain.
