FIRST ALERT WEATHER: Dense fog advisory in effect until 9 a.m., clear and sunny afternoon ahead

(WAFF) - A dense fog advisory is in effect for the Tennessee Valley until 9 a.m. Thursday. Visibility could be reduced to a quarter-mile or less, especially near rivers and lakes. Be sure to give yourself a few extra minutes of drive time during your morning commute in case you have to slow down.

Any fog should lift between 8 to 10 a.m. with skies becoming sunny for the afternoon. Morning temperatures are generally in the lower and middle 40s, which is some 20-25° cooler than we were yesterday morning. As skies begin to clear, temperatures will rebound into the mid-60s for highs.

Skies will stay clear Thursday evening and we should drop into the upper 30s for lows, causing some patchy frost to develop.

We'll see plenty of sunshine Friday afternoon with highs into the lower 60s.

Our next weather maker comes in Saturday in the form of a cold front. There won't be a lot of moisture for this system to work with, but you may notice more clouds for Saturday afternoon as it moves into the area. Temperatures Saturday will be in the upper 50s, but you'll notice a bigger difference that night.
