Assuming anyone is still reading this thread, more than likely it's just the serpentine belt whining a bit when it's cold and hard. Once it warms up it the little ridges on the underside loosen up and the noise goes away. You'll probably never hear it in the Summer, unless of course it's alwys cold where you live.
As the belts get older they are more prone to this, so if you've got a lot of miles you might want to consider this a warning to replace the belt in the next coupla months.
