Key Factors
- 01 Freeze Warning in effect until 9:00 AM EDT with temperatures as low as 22°F, raising risk of frost/ice on untreated surfaces such as bridges and overpasses
- 02 Daytime conditions are sunny with light winds (2-8 mph) and mild temperatures (47-55°F), favorable for driving
- 03 Rain showers likely after 11 PM with precipitation chance rising to 23% by late evening, though rainfall amounts expected under 0.1 inch
- 04 No fog, high wind, or winter storm alerts beyond the morning freeze
Recommendation
Safer to drive mid-morning to late afternoon, e.g., 10:00 AM–1:00 PM, and again in the early evening around 5:00–8:00 PM before overnight rain begins. Avoid pre-9 AM travel due to possible frost/ice on bridges.
