belt squeal maybe...?

well the weather has been getting colder these past few days and right when i start my car you immediately hear a squeal, for lets say 1.5-2 seconds, enough time for me to turn off my music and listen. ive read a few posts quick last night before my drive home from work, some were saying it could be a bad tensioner, glazed pulley, or just the belt rubber is cold and after its warm shouldnt be a problem, so i drove lets say, 2 miles down the road to fill up on gas and i turned my car on after, and it was gone. i assume the squeal has to do with the cold belt? if anyone has had this problem or knows what could be wrong please throw me some info.
