Key Factors
- 01 The alert text places the Frost Advisory through 8 AM EDT today; frost does not establish that roads are icy.
- 02 Rain chances are around 15–20% before 10 AM, potentially causing wet pavement; no snow or freezing rain is forecast.
- 03 Hourly temperatures remain above freezing from 7 AM through midnight, ranging from 37–50°F.
- 04 Northwest winds of 2–12 mph, with daytime gusts up to 22 mph, may require extra care in high-profile vehicles.
- 05 The Freeze Warning text specifies midnight–9 AM EDT April 21, outside today's driving windows; overnight freezing could affect any remaining wet surfaces.
- 06 Visibility and road-surface conditions are not provided, and alert metadata conflicts with the stated hazard windows; this assessment uses the explicit alert text.

Recommendation
Prefer 10 AM–noon EDT for morning travel and 6–8 PM EDT for evening travel. If flexible, avoid travel before 8 AM during the frost advisory; clear any windshield frost and check for slick surfaces. Increase following distance if morning showers wet the roads, and reassess conditions for trips extending past midnight.
