http://www.touringplans.com is a reliable website for crowd predictions. They predict that Fri-Mon will be elevated crowd levels due to the Superbowl. By their scale, normally the levels would be at 5 and 6 with some 4's. Superbowl weekend will be 7 and 8. Take a look over there to see what the levels will be like for the days you are considering.
Normally you have to have a current copy of the Unofficial Guide to see the whole calendar for about 1 year out, but the next month is always free to everyone.
Now, what does that mean? They have definitions based on E-ticket rides at MK peak wait times. However, if you are WDW experienced, you know how to work around the crowds, and how to use FP wisely, so you will probably never wait the peak wait times.
So here is my rule of thumb based on past experience with their crowd calendar: 4 is pretty empty - no need to worry about working around the crowds so much - just use common sense. 5 starts to get a bit crowded buts still very comfortable. 6 is fairly crowded, maybe a bit too much at times, but tolerable. Remember that some aspects of the parks makes it more enjoyable from a certain viewpoint to have things a bit crowded. Below 4 the parks can be quite dead, and not so lively and fun. Also, Disney has more elaborate entertainment (especially of the parade type) the more crowded it is expected to be.
7 starts to get a bit uncomfortable, but if you go early and late, use FP judiciously, and see attractions during parades and fireworks, you can make it work. 8 even a bit more uncomfortable so that in the middle of the day it is hard to get around and FPs will run out on some things.
I've never been there on 9 or 10 days. Usually these days are limited to the period from Christmas to New Year's, Easter week, July 4, and a few other days. At these levels, sometimes the parks close because of capacity issues.
This web site also gives advice on the best parks to visit and parks to avoid. I've found this information to be accuate as well.
Have fun if you go!
