Summary
Driving is generally safe for most vehicles today outside of the early-morning dense fog. A Dense Fog Advisory reduces visibility through 8:00 AM EDT; otherwise dry, above-freezing temperatures and only light to moderate winds are expected.
Key Factors
- 01 Dense Fog Advisory in effect until 8:00 AM EDT on 2026-03-21 with visibility as low as one-quarter mile — low-visibility driving hazard in the early morning.
- 02 Hourly forecast shows zero/very low precipitation probability for the day (0–2%), so no rain/snow/ice expected that would create slick roads.
- 03 Temperatures range from mid-40s to high-50s °F (well above freezing), so freezing/ice risk is negligible.
- 04 Winds northwest 7–13 mph (gusts not listed) — moderate winds that could affect high-profile vehicles but not a widespread driving hazard.
Recommendation
Avoid driving during the dense fog window: not recommended between 5:29 AM and 8:00 AM EDT. Safer time windows to drive today: morning — 9:00 AM to 11:00 AM EDT (post-advisory, good visibility); evening — 6:00 PM to 8:00 PM EDT (mostly cloudy, low precipitation chance).
