Scott,
Welcome to the club!
We have players installed from Alaska to Florida (and probably even more extreme climates), and there has not been a weather-reported problem. The most weather-sensitive component would probably be the hard drive, and Empeg Ltd. uses very good quality Laptop drives, tested by the manufacturer. So, if you could run a laptop, you can run the Empeg. Also, the car it's installed in will provide SOME shelter from nature's wrath.
This has been covered before; maybe you could search on 'Alaska'...
