Denver, Colorado Springs and Pueblo all hit record high temperatures Wednesday.
Forecasters also expect Grand Junction to tie or break records Wednesday and Thursday before moisture from Hurricane Emily could bring some relief this weekend.
In Denver, it was 105 degrees at Denver International Airport Wednesday afternoon, tying the hottest day of all time on record for the city back in 1878. Pueblo hit 106 degrees, surpassing the record high of 104 in 1998.
This week is typically the hottest time of year in Colorado, before the days start getting shorter and monsoon season arrives.
