It’s as if the fog is taunting drivers across Western Washington.

For the fourth day in a row, foggy conditions are impacting the Thursday morning commute.

For almost a week now, Seattle has been making its best impression of San Francisco. The conditions have been widespread Thursday morning.

Fog advisories last through noon Thursday, according to the National Weather Service (NWS) in Seattle.

NWS said that fog is caused by light winds, a stable low-level air mass (inversion/poor mixing), recent wetting rains (moist low-level air mass) and clearing skies.

Up in Snohomish County, “dense fog” was clearly impacting commuters’ visibility.

Residents traveling to Sea-Tac Airport (SEA) also described foggy conditions.

The Washington Department of Transportation (WSDOT) reminds drivers to use low beams or fog lights if you have them. High beams don’t help you to see better and are dangerous for oncoming traffic.

The fog will fade by midday followed by clouds and highs in the 40s.
