Key Factors
- 01 No active weather alerts are provided.
- 02 Rain chances are 79–97% from 8am–noon and 81–96% from 5–8pm; wet roads can reduce traction and rain can impair visibility.
- 03 Daytime rainfall of 0.25–0.5 inches is possible, with another 0.25–0.5 inches forecast for the overnight period extending into September 21.
- 04 Winds are mostly light, but the overnight forecast includes gusts up to 22 mph.
- 05 Temperatures remain well above freezing, with no snow or freezing precipitation forecast.
- 06 Visibility measurements and hourly rainfall intensity are missing; high humidity alone does not confirm fog.

Recommendation
Prefer 7–8am for morning travel, when the rain chance is 28%. For evening travel, 10–11pm offers a relatively lower rain chance of 57%, but rain and possible thunderstorms remain concerns; no evening slot is clearly dry. All times are local (UTC−04:00). If flexible, avoid the higher-rain-probability windows of 8am–noon and 5–8pm. Reduce speed, increase following distance, use headlights in rain, and postpone travel if heavy rain or thunderstorms impair visibility.
