Key Factors
- 01 Dense Fog Advisory until 10 AM EST with visibility one quarter mile or less; widespread fog forecast from 6 to 10 AM.
- 02 Rain chances climb to 66-88% during 8-10 AM, adding wet roads to the fog.
- 03 Steady rain is likely from 4 to 7 PM (79-91% chance), with total rainfall of about 0.1-0.25 inch, causing wet roads and reduced visibility during the evening commute.
- 04 Patchy fog returns around 8 PM and again near midnight, so visibility may drop again at night.
- 05 Temperatures stay 36-42F all day with an overnight low near 34F, so ice risk is low today, though temperatures near freezing early on Feb 19 warrant some caution.
- 06 Winds are calm (0-2 mph), so crosswind risk is minimal.
- 07 No hourly visibility values were provided beyond the alert, so exact fog improvement timing is uncertain.

Recommendation
Avoid driving before 10 AM if possible because of dense fog. The best morning window is about 11 AM to 2 PM, when the fog advisory has ended and rain chances are lower (23-32%). The best evening window is about 8:30 to 10:30 PM, after the heavier rain ends and rain chances drop to around 20%, but watch for patchy fog. If you must drive in fog or rain, use low-beam headlights, slow down, and leave extra following distance.
