As you can see from the map above, dense fog advisories extend from central Texas to North Carolina. Advisories are posted when the visibility is 1/4 mile or less. That’s about 1300 feet. Dense fog can be a persistent problem along the Gulf South this time of year after a spell of cold weather. A warm, tropical air mass will override that cold air, and create a perfect setup for fog. Fog is a winter hazard. Here’s the link to my previous blog about fog.

Snow is forecast for parts of Michigan, Wisconsin and Iowa. And, a winter storm is crossing the Cascades in the West.

Thunderstorms are delaying travel in the Miami-Ft. Lauderdale area this Wednesday morning. The FAA’s website has all the latest travel delays across the country. Check it before you go to the airport. If the sphere on the map is green where you are flying, you are good to go. If not, click on the yellow or orange sphere, and it will tell you the amount of the delay and the reason for it.
Currently, there are also weather delays in New York, New Jersey, Philadelphia and D.C..
No delays in the Midwest so far, but with an arctic air mass advancing toward the Great Lakes region over the next two days, minor accumulations of lake effect snow are a possibility.
The previous link shows you another awesome graphic from USA Today explaining lake effect snow.

As you can see, it takes a delicate combination of cold air near the surface, a cold, straight wind blowing across a warmer body of water, and some high ground on the leeward side of the lake for lake effect snow to occur.
Forecasters in northern Michigan, and parts of Illinois, Ohio, Pennsylvania and New York will be in for some interesting weather this holiday weekend. Go to the GET YOUR LOCAL TV FORECAST! link on the right hand menu bar, find the city your in, or where you are traveling, and follow their forecast.
I hope you and your family have a Happy Thanksgiving.
