How cold did it get in Denver? Aluminum and plastic have
different contraction rates with cold. Plastic also gets
brittle with cold. Wind flexes wing, which also flexes

Denver is considered "high plains desert", and is actually quite
moderate. Average temperature in February is around 33 degrees. It's
not unusual to get a blizzard, and then be out in short sleeves the
next day. (It'll be around 50 F tomorrow! )
It'd be a heckuva lot colder in many other places, so cold windshield
cracks make no sense, unless they used the wrong heating process as
Bob Moore suggests.
On the other hand, they mentioned 100 mph ground winds, and that means
flying rocks to me. Windshield replacement is a big business out
there due to so much gravel on the roads
