You might as well get used to the fog because it's going to stick around for the next couple of days. The fog that we are experiencing today is known as advection fog and is a little different than the raditional fog we're used to seeing. Advection fog forms when a relatively warm and moist air mass moves over a cooler ground surface, like the snow covered ground we have now. The word advection means to transport, or move, horizontally. It's different from raditional fog because it can form when it is cloudy or when there is wind. With a southerly wind expected through today and Friday the fog will likely stick around until our wind direction changes to the north and brings in drier and cooler air.
7:00am Update: A Dense Fog Advisory has been issued for all of the WTVO forecast area until Friday evening. Dense fog has developed as warmer temperatures and moisture continue to advect northward across the Stateline. While visibility may improve some, expect the fog to last until a strong cold front moves through Friday night. Until then take it easy and give yourself plenty of time the next two days.
