Key Factors
- 01 Frost Advisory until 8 AM EDT with temperatures as low as 33-38°F, creating potential for icy patches on bridges and overpasses early morning
- 02 Slight chance of rain showers before 10 AM (under 20% probability) with near-freezing temps could briefly create slick spots
- 03 Freeze Warning takes effect again at midnight tonight into Tuesday morning with temps dropping to the low 30s/upper 20s
- 04 Wind gusts up to 22 mph from the NW are modest and pose minimal risk
- 05 Afternoon and evening conditions are dry, clear, and calm with no precipitation expected
Recommendation
Morning slot: Drive after 9 AM EDT once temperatures rise above 40°F and frost has dissipated. Evening slot: Drive between 5-7 PM EDT while temperatures are still in the mid-to-upper 40s and skies are clear. Avoid driving after midnight when sub-freezing conditions return.
