DENVER — After record-tying heat both Thursday and Friday, the weekend brings a significant change to the Denver area. Temperatures will struggle to reach the mid-80s Saturday.
Friday hit 101 degrees for the first time since June 2018 and marks the 92nd time in 147 years of record keeping that Denver reached at least 100 degrees.

The change arrives Saturday.
A cold front arrives by midday Saturday, and that front cools off most metro areas by 10 to 20 degrees for Saturday afternoon. That means the northern Front Range will be in the upper 70s to mid-80s. Wind will be stronger as a result of the clash between the recent heat and the arrival of the colder air.
Along with the cooler weather comes the chance for widespread thunderstorms. Although the storms will primarily bring rain and a lightning threat, conditions will have to be watched for a hail threat as well.
These storms will be most active from midday through early evening.
Those in the high country enjoying the outdoors need to keep an eye to the sky and seek shelter as soon as a storm is spotted; lightning strikes will be frequent.
Outdoor plans may be impacted Sunday too.
Showers and thunderstorms will continue Sunday and Monday, with highs in the 70s to low 80s.
As conditions dry Tuesday, the area will have an extended period of isolated thunderstorm chances and temperatures running from the 80s to low 90s.
The outlook for the last week of July is cooler than average for Colorado and most of the country. The current heat gets pushed back to the west. pic.twitter.com/gb9HCcgXMQ

A return of the triple-digit heat is not expected through the end of July. This is partly due to a bit of a wetter outlook for the last week of July (not part of the monsoon, which is not impacting Colorado this year).
Although history does not agree, modeling and CPC data indicate a bit of monsoonal flow in the 8 to 14 day period that may bring above-average precipitation to the Rockies. History, however, shows similar patterns remain dry. pic.twitter.com/IduAfZa0Ng
