Bad bearing?

So I started the jeep up the other day and a sort of howling/whirring noise started coming from the front of the engine. I believe it's coming from the AC unit that's driven by the belt. It's fairly loud, but it fades after about a minute of warming up.

It's been colder than usual but I'm not sure that has anything to do with it. Anybody got any thoughts on where to start?

Grab a long screwdriver, place it on different areas of the engine running and put your ear to it. Be careful around the fan, it will catch you and mess you up if you get too close.

Check and properly set the fan belt tension. Inspect the fan belt. Replace if necessary. As suggested look/listen for noisy bearings.
