The 105-degree reading is also the highest temperature recorded in Denver and has only been reached four times:

  • June 26, 2012
  • June 25, 2012
  • July 20, 2005
  • August 8, 1878

The old record high for June 26 is 104, set in 1994. Tuesday is day number five in a row of 100-plus degree heat. That ties the longest stretch in Denver history. This happened twice before from July 4 to 8, 1989 and from July 19 to 23, 2005.

A RED FLAG WARNING has been issued for the foothills west of Denver and Fort Collins to the western slope. Southwest Colorado and locations from Colorado Springs to the south remain under the warning, as well from noon until 9 p.m. Tuesday. The extreme eastern plains will have extremely dangerous fire conditions as well.

Dry, hot and gusty conditions are expected throughout the warning area. Winds will be out of the southwest from 10 to 20 mph with gusts to 35 mph during Tuesday afternoon.

The biggest concern, however, will be the chance for gusty thunderstorms. Storms will form along a large ridge of high pressure located over the Front Range and eastern plains.

Most locations expecting storms will be over the high country and Front Range foothills. Due to the extremely dry conditions across Colorado storms will not produce much rain, rather wind gusts to 50 mph and lightning, posing a threat to the fire fighting efforts. Storms will be forming just after 2 p.m. and will last through the evening.

Excessive heat will also continue across the state on Tuesday. Temperatures along the Front Range will once again top the triple digits.

Temperatures are expected to dip below 100 Wednesday, steadily falling into the lower and middle 90s by the weekend.
