Life-threatening situation on I-25 between Wellington Colorado and Cheyenne Wyoming as a blinding whiteout grinds the interstate to a standstill in -30 to -40 windchills. If you are stuck in this absolutely do not turn your car off! Stay warm! @NWSCheyenne @NWSBoulder #cowx #wywx pic.twitter.com/SW98Vha8nB

The temperature drops of 40.8°F in 30 minutes and 42.3°F in an hour at Christman Field (western Fort Collins) are easily the biggest in the records at this station. (Data back to 1997.) @NWSBoulder #cowx pic.twitter.com/MvoJ4vfEgT

At the NREL Flatirons tower (S of Boulder), it dropped 10.8°F (6°C) in one minute & 20.9°F (11.6°C) in two mins at 50 meters above ground, which is not far off from what I consider the benchmark of 14.4°F (8°C) in one minute on 19 Sep 1983, reported in Shapiro et al (1985). #cowx pic.twitter.com/pcx2bvyW0U
