I keep track of daily low temps across the nation, and it might interest some of you that Mt. Washington had the lowest temp in the lower 48 on the following days this year:
Jan 10 at -18 (Alamosa, CO, was next at -15)
Jan 17 at -32 (Craig, CO, was next at -27)
Jan 20 at -22 (Wakefield, MI, was next at -19)
Jan 25 at -28 (Saranac Lake, NY, was next at -26)
Jan 26 at -33 (Watertown, NY, and Whitefield, NH, were next at -18)
Mt. Washington doesn't get listed in the NWS report for lowest temp for those days since it officially doesn't have any population. For each of these days, at least one village in Alaska beat Mt. Washington, but five 'lower 48' national lows in one month is pretty good!
