Key Factors
- 01 The Extreme Heat Warning text runs through 8 PM EDT, despite inconsistent structured alert end times. Expected heat indices of 100–110°F increase heat-illness risk.
- 02 Thunderstorms are possible from 2 PM onward, with precipitation probabilities reaching 62% at 8–9 PM and 65% at 10–11 PM. Heavy rain could reduce visibility and traction.
- 03 Morning precipitation probabilities are only 2–6%; forecast sustained winds of 1–12 mph are not a major concern.
- 04 A code orange air quality alert applies Saturday and may affect sensitive occupants.
- 05 Visibility measurements and wind-gust forecasts are missing, limiting assessment of storm-related driving hazards.

Recommendation
Prefer 7–9 AM EDT for cooler temperatures and minimal rain chances. If evening travel is necessary, 9–10 PM EDT is a relatively better slot between higher-probability storm periods, but its 44% precipitation chance means it is not reliably safe; travel only if storms have cleared your route. Avoid thunderstorms from 2 PM onward, particularly 8–9 PM and 10 PM–midnight. Use air conditioning, stay hydrated, never leave children or pets unattended in vehicles, and slow down and increase following distance in rain.
