The benchmark for most precipitous *immediate* cold snap I've experienced in #Denver was on February 18, 2018, when (according to a personal weather station in the neighborhood), our temperature fell:
• 9.6° in 10 minutes
• 17° in 25 minutes
• 22° in an hour
• 36° in six hours
• 43° in 12 hours
• 57° in ~17 hours
• 69° (not nice!) in ~38 hours
Tomorrow I'll be watching *my* new personal weather station (https://bit.ly/MMHwx) to see how this #coldfront measures up!
#CentralPark #Denver's top five* 15-minute temperature drops in the last decade or so:
2/18/2018: -13.0° (53.7° to 40.7°)
12/3/2013: -8.5° (57.7° to 49.2°)
12/29/2017: -7.5° (53.9° to 46.4°)
9/7/2020: -6.8° (88.6° to 81.8°)
10/9/2019: -5.1° (69.5 to 64.4°)
*I think. I might have missed one or two. ¯\_(ツ)_/¯
Those were all the precipitous beginnings of ~50-70° temperature drops over the course of 24-48 hours.
That 9/7/2020 one is the most memorable. We went from 93°(!!) on a Monday afternoon to 35° and snowing on a Tuesday morning.
