Ok guys... cold air is more dense. That means two things are true:
1) LESS High Speed Stability (more high speed turn aka flippy)
2) MORE Low Speed Stability (more low speed fade aka fade... (just go with it))
Denser air will create a larger air pressure difference between the top and bottom of your disc than less dense air, which causes lift and will push your disc up and over more easily. However denser air has more drag than less dense air, which will slow the disc down quicker and cause it to hyzer out faster.
Personally i use discs that have nuetral flight ratings in winter and rely more on release angles than understable/overstable flight characteristics.
Lastly, there's grip differences. Getting less of a good grip on cold plastic will decrease distance as there is less potential energy transfer from your fingers to the disc with a weaker grip.
