Key Factors
- 01 Early morning temperatures of 33–35°F (7–9 AM) are near freezing, raising the risk of residual ice or frost on road surfaces, especially on bridges and overpasses.
- 02 Wind gusts up to 23 mph are forecast during the daytime, which may affect vehicle handling, particularly for high-profile vehicles.
- 03 Overnight precipitation probability rises to 96–100% after midnight, with heavy rain (0.25–0.50 inches), possible thunderstorms, and wind gusts up to 28 mph creating hazardous late-night driving conditions.
- 04 Humidity rises sharply through the evening (58–86% from 7 PM to midnight), increasing the risk of wet roads and reduced visibility as rain approaches.
- 05 No active weather alerts are in effect, and daytime conditions are largely benign with low precipitation probability (under 10%).

Recommendation
Morning window: Prefer driving between 10:00 AM and 12:00 PM, after temperatures have risen safely above freezing (38–43°F) and before winds pick up significantly — this is the lowest-risk window of the day. Evening window: If evening travel is necessary, aim to complete it by 7:00 PM (19:00) before humidity and precipitation probability climb steeply. Avoid driving after midnight due to heavy rain, potential thunderstorms, and strong gusts up to 28 mph.
