So I am driving home from the inlaws and I start to hear this howling noise. I cant figure out if it is coming from my Altima's wheel well or the side mirror. I normally hear this type of noise in my WRX when I am exceeding 100mph. I call it the 100mph howl. I was only going 80mph and I kept hearing this sound.

Any sugguestions?

BTW we have had wind gusts at 35mph.

Check that your inner fender well plastic is still attached at the front. I have heard too many stories of that plastic being caught under the tires and being torn off.

my altima is amazingly quite even over 1oo mph, but i do hear a lil bit of a howl at about 11o or so
