Check the fan clutch. That's what it sounds like to me. It may need to be replaced. They cost $50-60. I've never tried to take one apart or fix one, I just replace it.

Belt squeal because it's slipping would be my guess. The belt tensioner is probably wearing out and not putting the tension like it used to and the moisture in the air when it's cold is making it slip

Yep belt squeal, if it has just started to do this check the belt for glazing If it is glazed then replace it, if not then check the belt tensioner for proper tension, if that checks good then check the fan clutch with the engine warm, the fan should freewheel, if that checks good then have the battery and charging system tested, your battery maybe getting weak causing the alternator to go full field on start up causing the belt to slip even though it looks good.

I know this is an old post, but thought I would add anyway. My 2007 2500 started doing the same thing last year. Especially on cold starts. Very soon it started having shifting issues. Took it to mechanic and found out the torque converter was going bad. $850 to replace, but that was the problem. Mechanic knew it as soon as he heard it
