When performing Non Destructive Testing (Industrial Radiography) Surveys, 
I have observed a big difference in skyshine scatter.  Same location, same 
source intensity, different precipitation.  Snowy days did seem to give 
the greatest amount of skyshine, like jumping up 25% or more than a clear 
day but the distance wasn't thousands of feet, In my experience it was 
maybe dozens of feet away.  I would think it would be worse in a day of 
"precipitation" (snow/rain)  where your sky shine comes from closer 
scattering points than higher altitude clouds.
