Key Factors
- 01 Freeze Warning in effect overnight into April 21 with temps dropping to ~26F, raising risk of icy patches late evening/early morning
- 02 Frost Advisory until 8 AM EDT — possible frost on roads, bridges, and overpasses
- 03 Slight chance of rain showers before 10 AM combined with near-freezing morning temps (38–40F) could create slick spots
- 04 NW wind gusts up to 22 mph — minor crosswind risk for high-profile vehicles
- 05 Daytime conditions otherwise dry with partly to mostly sunny skies
Recommendation
Safer to drive mid-morning to afternoon (about 10:00 AM–4:00 PM) once frost clears; in the evening, 5:00 PM–8:00 PM is best before temperatures drop toward freezing. Avoid driving before 8 AM due to frost, and use caution late at night as a hard freeze sets in.
