Summary
Data for the evening of March 19 (10-11 PM EDT) shows partly cloudy skies, light wind, and almost no chance of precipitation. The main concern is an overnight low near 34F, which could allow isolated icy patches on untreated surfaces.

Key Factors
- 01 Precipitation chance is 0-2%, so no rain, snow, or freezing rain is expected in the covered window
- 02 Wind is only about 2 mph, so there is no crosswind or gust risk
- 03 Hourly temperatures are 41F, but the overnight low is forecast near 34F, which is close enough to freezing that frost on bridges or shaded spots is possible
- 04 No active weather alerts were issued
- 05 Visibility data is not provided, and the data covers only 10 PM onward, so daytime and morning conditions are unknown

Recommendation
Evening driving from 10 PM to midnight is fine under these conditions. No morning slot can be confirmed because the data starts at 10 PM, but the early-morning window from 10 PM to 6 AM is forecast dry with temperatures of 34-36F, so watch for frost on bridges and overpasses and allow extra braking distance. A safer morning time is after about 8 AM when temperatures are likely to warm above freezing, though this is unconfirmed by the data.
