If it was tough to see this morning in your neighborhood, it could be again Wednesday morning. If you have to go to work or are headed out early to beat the holiday travel traffic, be prepared to fire up the low beams. This morning's visibility dropped below 1/2 mile for a while; the same thing could happen again tomorrow.
It's been a mild day - the high at Bush Airport was close to 80°. Typically at night the air cools, but can't drop below the dew point - a measure of the amount of moisture in the air. Over night dew points are forecast to be in the mid 50s which is about where the temperature will settle. If the difference between those numbers is less than a few degrees, fog will begin forming. It may not lift again until a few hours after sunrise, say 9 or 10 am.
This pattern holds one more day until a cool front moves in early Friday. It shouldn't be a big problem for Black Friday shoppers, but should usher in cooler weather by the weekend.
