Key Factors
- 01 Freeze Warning is in effect until 9:00 AM EDT (sub-freezing temps as low as 22°F), which could create icy/slick spots early morning.
- 02 From 12 PM through around 9 PM, temperatures stay mostly in the 47–55°F range with sunny/mostly cloudy conditions, suggesting limited ice risk.
- 03 Precipitation risk increases late: rain showers are likely after 11 PM, with probability of precipitation rising (23% from 11 PM–12 AM, and 60% overnight after 11 PM per daily forecast).
- 04 Wind is light to moderate (generally 3–9 mph), so no strong crosswind/high-wind hazard is indicated in the provided data.

Recommendation
Safer driving windows: (1) Morning: after the Freeze Warning ends, roughly 9:00–11:00 AM EDT (to avoid any pre-9 AM freezing/ice risk). (2) Evening: before the late-night rain, roughly 7:00–10:00 PM EDT. Use extra caution after 11 PM due to likely rain showers.
