Key Factors
- 01 Heat Advisory is in effect until 8:00 PM EDT, with heat index values up to around 97-98°F.
- 02 Afternoon temperatures rise into the mid to upper 90s, peaking around 96-97°F from roughly 2:00 PM to 5:00 PM.
- 03 Winds increase through the afternoon, with sustained speeds around 12-14 mph and daily gusts up to 25 mph, which is manageable for most drivers but may affect high-profile vehicles slightly.
- 04 Precipitation chances remain very low (around 1-5%) and the forecast is mostly sunny/partly cloudy, so wet-road risk is minimal.
- 05 No fog, snow, ice, or visibility restrictions are provided, but visibility data is not explicitly included, which adds some uncertainty.

Generally safe to drive today, but avoid the hottest stretch from about 2:00 PM to 6:00 PM if possible. Safer morning slot: 7:00 AM-10:00 AM EDT. Safer evening slot: 8:00 PM-11:00 PM EDT, after the Heat Advisory ends and temperatures begin easing.
