Will wet snow on Pac Yagis cause signal loss?
Yes. Not only that, it will change the pattern for the antenna.
Does frozen snow on trees block less than wet (melting?) snow on trees?
yes and no. The difference being that if it is hard frozen, you will see a (slightly) higher amount of signal that is reflected and refracted vs just absorbed. Either way, water (whatever it's temp) is a killer for 2.4GHz signal. At 900MHz, you get a bit less absorption through water. I think what you are seeing is the reflection/refraction changing as the temperature of the snow in the way changes.
