Alaska doesn't have any official weather stations at high altitudes similar to the likes of Stanley and West Yellowstone, despite of the state's largely mountainous topography. Otherwise, there would be no lower-48 locations showing up in the daily extreme minimums log.

McCarthy says the guidelines for temperature eligibility are:
•High and low temperature must be from the conterminous U.S. (excluding Hawaii and Alaska)
•The elevation must not be above 8,500 feet.
•The location must have a population of more than 1,000.
•"Exceptions are made for particularly noteworthy sites such as Death Valley, Calif.," he says.
The USATODAY.com Weather team adds temperature data for Alaska and Hawaii, when one of these states has the highest or lowest for the entire USA. We use data from the temperature and precipitation summaries transmitted from the Anchorage, Alaska and Honolulu weather service offices. When Alaska has the coldest U.S. temperature or Hawaii the warmest, we also list the coldest or warmest for the 48 contiguous states because we know that many weather buffs track these figures.

•High: 118 at Baker, Calif. (128 at Death Valley, CA)
•Lows: 34 at Eureka, Alaska (contiguous 48 states: 40 at Houlton, Maine; Spincich Lake, Mich.; and Stanley, Idaho)

Are these guidelines only for that specific source? There are plenty of locations that hold records for all-time state temperature extremes that don't meet one or more of those. I can't for the life of me figure out where Pond, AR even is.
Supposedly it says:"The national high and low temperature for the contiguous 48 states are compiled by the National Weather Service's Hydrometeorological Prediction Center in Silver Spring, Md., says Kevin McCarthy, Deputy Director of HPC. The national high and low are determined from information provided by local National Weather Service offices. "
I know that yesterday's low in the lower 48 was 40F, not including Alaska, but here in Fraser,CO it was 38F. But since that city is at an elevation of 8574ft. and a population of 910, it wasn't included, even though the Denver Post did list it as the national low. So I guess it really doesn't matter too much, but I guess for "official" purposes, they list those rules.
I did notice the link Cambium gave me lists Death Valley, while the other link I use too, doesn't list it, so now with both links, I can see what's "official" or not.
This link is for the Denver-Boulder area, but using the location tab you can easily go to any area of the country. The NOWDATA tab gives the capability to pull up both current stats on temperature and cumulative season snowfall, as well as seasonal averages. It's very useful in the winter to identify local variations in snowfall, for example.
Last year, Denver received 55.6 inches of snowfall, while Boulder got 94.7, Loveland got 62.7 and Ft. Collins only 49.9 inches. Temperatures were about average for the winter, but the Spring brought temps. much above normal.
It's a great resource for very localized statistics.
