Key Factors
- 01 Freeze Warning in effect until 9:00 AM EDT, with sub-freezing temperatures as low as 22°F that could create localized slick spots early.
- 02 From 12:00 PM through the evening, forecast conditions are dry with low precipitation chances, temperatures in the upper 40s to mid-50s, and light winds around 3 to 9 mph.
- 03 Rain showers become more likely after 11:00 PM, which can lead to wet roads late tonight.
- 04 No visibility data is provided for the morning freeze period, so early-road impacts are somewhat uncertain.
Recommendation
Safest morning slot: after 9:30 AM to 12:00 PM, once the Freeze Warning has ended and temperatures are above freezing. Safest evening slot: 6:00 PM to 10:00 PM, before rain chances increase more notably late tonight; avoid the early morning before 9:00 AM and use extra caution after 11:00 PM.
