Key Factors
- 01 A Special Weather Statement was issued at 5:05AM EDT for areas of fog, with some patches potentially dense (visibility of a quarter mile or less) — this hazard was concentrated in the early morning hours before 7AM
- 02 High relative humidity of 93% at 7AM and 90% at 8AM indicates residual fog or mist risk in the early morning
- 03 Humidity drops steadily through the day (down to 51% by 4PM), signaling fog dissipation as the morning progresses
- 04 Light north winds of 5–8 mph throughout the day pose no significant crosswind or high-profile vehicle risk
- 05 Zero probability of precipitation during the daytime hours; negligible (2–3%) in the early evening, which is non-threatening
- 06 Temperatures are well above freezing, eliminating any ice or frost risk
- 07 No severe weather alerts beyond the early-morning fog statement

Recommendation
Morning: If possible, delay driving until 10:00AM–11:00AM EDT, when humidity has dropped to around 74% and the fog risk has cleared. If you must drive earlier, slow down, use low-beam headlights, and increase following distance significantly. Evening: Conditions are favorable for driving between 6:00PM–9:00PM EDT — partly cloudy skies, temperatures in the low-to-mid 70s, light winds, and near-zero precipitation chance make for a safe and comfortable commute.
