Monday, 15:00Z, Tuscaloosa, AL:

Area forecast: VFR

Nearest TAFs: Better than 5,000-and-5 for at least 12 hours.

Nearest METARs: Better than 5,000-and-5.

Surprise! KTCL ASOS: Visibility less than 1/4 mile, freezing fog.
Indefinite ceiling 100. Temperature -2, dewpoint -3.

The airport's next to a river.

My pax was waiting for me in the FBO, so after a miss on the ILS RWY4, there
was nothing to do but hold for an hour 'til the weather came up.

Moral: never underestimate local weather factors no matter what the forecast
says. Arrive with plenty of fuel, just in case.
