seems to happen a lot more often when its raining occasionally when cold. Start the car, loud squeal from engine. after awhile it seems to lessen but never really go away until after about 10-15 mins. is there a fix to this?

It is more than likely your accessory belt. Possibly the timing belt or other tensioners/pulleys, but unlikely. Pop the hood to try and find the source of the sound. Alternatively, remove the accessory belt and start the car and see if it makes the sound.

 

I'm not a car guy at all. is this easy to do?

 

If you're mechanically inclined, its pretty easy but honestly it sounds like you should just take it somewhere and have them look at it
