Spearfish holds the world record for the fastest recorded temperature change.

On January 22, 1943 at about 7:30 a.m. MST, the temperature in Spearfish was −4°F (−20°C).

The Chinook wind picked up speed rapidly, and two minutes later (7:32 a.m.) the temperature was +45 °F (+7 °C) above zero.

The 49 °F (27 °C) rise in two minutes set a world record that still holds.

By 9:00 a.m., the temperature had risen to 54 °F (12 °C). Suddenly, the chinook died down and the temperature tumbled back to −4 °F (−20 °C). The 58 °F (32 °C) drop took only 27 minutes.

    They had global warming in 1943?

      Well, WARMING. It is IRONIC! When I went to school, they told us there would be a GLOBAL COOLING(ICE AGE). Around 1990, they said there would be a GLOBAL WARMING. NOW, they say there is a GLOBAL CLIMATE CHANGE! MAN OH MAN, I just realized I fell into the trap! GC? It hasn't happened yet, so far as anyone knows. GW? It hasn't happened yet, so far as anyone knows. GCC??????

      OF COURSE there is a Global Climate change! OF COURSE! There is a field of science DEVOTED TO IT! There are CAREERS devoted to it! YEP! And WHEN did it start? Well, technically, the bible implies it kind of started from the first day. We know it happened on 1/1/0000 They talk about it even in the pyramids! Every language I tried to learn had words DEVOTED to it! They are among the first you learn! And HEY! Cheryl Scott at least WAS in one of those careers back in 2013! You want to see her?

    And this had absolutely nothing to do with the detonation of the first atomic bomb in New Mexico earlier that day?

      You have a point! SUPERHEATED air(Due to the primary explosion, and the secondary one of nuclear components going critical) going as fast as possible, is BOUND to heat nearby states. I wonder if colorado and nebraska ALSO had temperature shifts. Since it WAS hot air, it likely wouldn't make it colder, and it wouldn't make it hotter than the air. So the difference likely wouldn't be as big or noticable in colorado and nebraska,

    Did anyone check the date for any, ahem, secret government underground tests that just happened to be going on at that time?

    BOOM! Wow it got warm fast, must be some kinda record.

      YEAH! I should have noticed that it was so close to 1945, and before it. I imagine a LOT of tests were going on. The US was losing allies, as the NAZIs were trying to destroy them, and the germans were coming out with weapons that made everything else obsolete. The ONLY hope was to somehow wipe out germany, or show such an overwhelming force that people HAD to surrender. It didn't help that EVERYONE was trying to develop the bomb. IIRC the allies ended up destroying the preliminary efforts of the japanese and the germans, kind of by accident! It was collateral damage from other attacks.

      HEY GUYS! Ever see hiroshima or nagasaki? They actually never had an atomic bomb actually hit the city! Nagasaki had a blast from about 1/10 of a mile above it. HIROSHIMA had a blast from about a MILE above it. And have you seen pictures of the effects? The "SHADOWS" of some people are ETCHED into concrete! The HEAT was THAT high!

      https://www.reddit.com/r/pics/commen...m_permanently/

      Anyway, the normal winds, together with down and out pressure from the explosion, would cause that heat to spread out a LOT, and I don't know if ANYONE determined how far that would go. The badly burned area of nagasaki(the least destroyed of the two cities) was 3 MILES! IMAGINE a flash fire obliterating 3 miles in perhaps less than a minute.
