Key Factors
- 01 Active Extreme Heat Warning beginning 2026-06-30 02:44 EDT (dangerous heat; in-vehicle heat risk if stopped/stranded).
- 02 Temperatures rise from ~70°F in the morning to ~91°F mid/late afternoon, increasing driver fatigue/heat stress risk.
- 03 Slight chance of showers/thunderstorms after ~17:00 EDT through the evening/night (precip chances ~17–20%), which could briefly reduce visibility and make roads slick.
- 04 Winds are relatively light (about 3–10 mph), so no significant crosswind hazard indicated.
- 05 No visibility data provided (e.g., fog/smoke), so confidence is reduced somewhat; separate Air Quality Alert text is for 6/29 and does not clearly cover 6/30.

Recommendation
Morning safer slot: 07:00–11:00 EDT (sunny, very low precip chances, lighter heat). Evening safer slot: 19:00–22:00 EDT only if storms are not occurring; otherwise avoid driving during/near any thunderstorm cells from ~17:00 EDT through late evening and delay until conditions clear. Keep extra water, avoid leaving people/pets in the car, and minimize time parked/idling in the heat.
