From a heat index of 95 to a wind chill of 25 in just 14 hours - that's a drop in feels-like temp of 70 degrees:
Incredible. Incidentally the fastest temperature drop on record was in Spearfish, South Dakota in 1943:
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).
The fact that this is from a full blown cold front and not the odd event that is a Chinook wind is incredible.
The 24 hour temperature change record occurred in Loma, Montana in 1974:
The largest temperature change ever recorded within 24 hours took place in Loma, Montana. An extreme 103 F temperature range in less than a day occurred in January of 1974!
Amazing stuff.
