 DENVER (CBS4) – A record high temperature was shattered in Denver at 2:20 p.m. on Thursday when the temperature at Denver International Airport hit 105°F. It’s the fifth time that Denver has recorded a temperature this high since records began in 1872.
– Denver experienced its very own Rocky Mountain high on Thursday, when thermometers hit 105 degrees, tying the city’s all-time record set on June 26, 2012, reports CBS News. Other places in Colorado were even hotter. On Thursday, Lamar, Colo., scored a sizzling 109, notes the Denver Post. The heat, winds, and low humidity increase risk of fire, and much of Colorado has been under a red flag fire warning. Forecasters predict temperatures will drop to the low 80s by Saturday, which should bring relief. Meanwhile, much of the central and eastern US can expect to bake through the weekend, reports USA Today. Heat advisories, watches, and warnings were in effect for 18 states, and cities such as Chicago, St. Louis, and Detroit will likely open emergency cooling stations. The Northeast can expect to break some heat records of its own. (The people of Nawabshah, Pakistan might not be impressed by Denver's record.)
