Snow will have that effect.

What are you showing for noise levels?

Experience says I worry about anything that is worse than -75 reality says I have reliable links as bad as -84 still pushing 5-7 megs of throughput...

Guess it depends on how much snow.. last winter i had no problems at all with snow, but we're talking of not much (about 70 cm and 5/6 times)
We do not use any grid, just panels, and this may help -.
