not to ention the fact that the snow when it turns to water will get into the cable and ruin it. the exception is N type connectors which are gasketed and waer tight if one properly  even then you should always keep yoru coax out of the weater at it's ends
 I had to replace a run that I didn't realise was no loner weaherproofed, because it took 100w to get to th elocal repeater... it's amazing what a little water can do.
I'd have tried baking the coax but my foster dog I had at the time foudn the cable rolled up and decied it was a toy 
and you are all correct about switcing power supplies  they can be effeted by rl running around the shack. rounding and ferrite  chokes on all the cables will probably solve it, but don't neglect to check yoru antenna. a broken connection up at the diole for example can cause rf to come back down the outside of yoru cable, or unbalance a ladder r window line as well
