Yes, Alaska too. 7 hours even sometimes, certainly in a day or so it can go from -30 to +20 once or twice in an average winter.
I've heard the old 'if you don't like the weather here, just wait 5 mins. and it'll change' all over the world, in several languages.
Isn't there some place on earth with the world's least-changing weather? That'd be terrible for photography! One regret is interior AK doesn't get much violent weather, unlike the great storms I experienced in Michigan, central Russia, and Missouri... The palouse was weather-lame, too.
I take my hat off to you sir, I can't even imagine -30.
