"Major Towns" = ?????
Many locations (not necessarily towns, but locations) on the road system in Alaska don't have unduly heavy cloud cover in December. While any specific day can vary, from recent personal experience, I was driving between Eureka and Glenallen in early December (may actually have been the last day of November) about 8:00 pm in 2011 and there were some pretty fantastic aurora displays. Similarly, circa Dec. 12, I was driving between Talkeetna and Squarebanks sometime between 1430 - 2200 and the sky was crystal clear. No aurora that night, but the sky was clear. On that same trip, although it was in the early a.m. on the following day, once I got out of the Ice Fog/Smog of Fairbanks, the sky was again clear on the Richardson Highway.
