Summary
Driving conditions look generally workable, but extreme heat (heat index up to ~105°F) and isolated thunderstorms starting after about 1 PM could create localized hazards (heat stress, sudden heavy rain, lightning). Winds are light (~5–9 mph), and widespread precipitation is not indicated (around 20–24% chance).

Key Factors
- 01 Extreme Heat Warning is in effect per alerts; very hot afternoon conditions (high near 97°F; heat index up to ~105°F) increase risk of heat illness, dehydration, and vehicle overheating, especially if stranded or in stop-and-go traffic.
- 02 Isolated showers/thunderstorms are forecast after ~1 PM through evening/night (probability ~16–24% hourly). Any storm could briefly reduce traction/visibility and create hazardous driving conditions in affected spots.
- 03 Alert timing is internally inconsistent (headline implies warning continues into July 4, but the provided alert 'to' time is 12:00 PM July 1), creating uncertainty about the exact warning window.
- 04 No visibility or rainfall-intensity data is provided, so storm impacts on visibility/hydroplaning risk can’t be quantified.

Recommendation
Morning safer window: 7:00–11:00 AM EDT (sunny, low precip chances, cooler than later). Evening safer window: 9:00–11:00 PM EDT (cooler than peak heat, but still watch for isolated storms). If possible, avoid or minimize driving 1:00–8:00 PM due to peak heat and the higher chance of pop-up thunderstorms; keep water in the car and don’t leave children/pets in parked vehicles.
