Colorado Springs Windstorm

Holy hell we got hammered by Chinook winds (see Chinook tidbits below) over the last three days:

  • Monday 1.9.17 – Weather station registered a gust of 77 MPH, and sustained winds of 50 mph
  • Tuesday 1.10.17 – Gust of 74, sustained of 45 mph
  • Wednesday 1.11.17 – Gust of 66, sustained of 30 mph

Trees were down all over town, semis flipped on their sides all along the highway, roofs ripped off, fences down (update 1.23.17 Home Depot and Lowes are still out of lumber), power lines down, houses and cars crushed by trees. Fort Carson and Cheyenne mountain were forced to shelter in place due to ludicrous 100 MPH winds. The official wind gusts from NWS (including record setting gusts … three of them … over 80 MPH at Colorado Springs Airport).

Chinook wind craziness:

  • Loma, Montana, boasts having the most extreme recorded temperature change in a 24-hour period. On January 15, 1972, the temperature rose from -54 to 49 °F (-48 to 9 °C), a 103 °F (58 °C) change in temperature, a dramatic example of the regional Chinook wind in action.
  • The Black Hills of South Dakota are home to the world’s fastest recorded rise in temperature. On January 22, 1943, at about 7:30 am MST, the temperature in Spearfish, South Dakota, was -4 °F (-20 °C). The chinook kicked in, and two minutes later, the temperature was 45 °F (7 °C). The 49 °F (27 °C) rise set a world record, yet to be exceeded. By 9:00 am, 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.
  • The aforementioned 107 mph (172 km/h) wind in Alberta and other local wind records west of the 100th meridian on the Great Plains of the United States and Canada, as well as instances of the record high and low temperature for a given day of the year being set on the same date, are largely the result of these winds.
