Key Factors
- 01 Heat Advisory in effect until 8:00 PM EDT; heat/humidity can increase driver fatigue and vehicle overheating risk during stops/traffic.
- 02 Thunderstorm chances increase starting around 1 PM; showers/thunderstorms likely 5–7 PM and again late evening (around 10–11 PM) based on hourly and daily forecasts.
- 03 Periods with higher precipitation probabilities (roughly 3–7 PM at 40–65% and around 10 PM at ~63%) increase risk of wet roads and sudden downpours.
- 04 Wind gusts up to about 23 mph possible during the day (per daily forecast), which can make driving less comfortable—especially for high-profile vehicles.

Recommendation
Safer morning window: 7:00 AM–12:00 PM EDT (sunny, very low precip chances). Safer evening window (relative): 7:00 PM–8:00 PM EDT has the lowest listed precip chance (~34%), but still be prepared for rain/thunderstorms; avoid driving if storms are observed or warnings are issued. Highest-risk window to avoid if possible: ~1:00 PM–7:00 PM EDT (thunderstorm chances rising to likely).
