A huge cool off is coming for Thursday, which includes high temperatures that we haven't seen since the middle of May.
The record high for Sept. 10 is 93 degrees - last set in 1998. Sunshine and a southwesterly breeze will help temperatures warm into the low 90s Monday afternoon. In fact, the Denver forecast calls for a high of 93 degrees - matching the record set more than a decade ago.
However, a series of disturbances moving across Colorado will change the forecast dramatically by the end of the week.
The cool down begins Tuesday afternoon with a slightly better chance for isolated storms along the Front Range and highs in the middle 80s. Denver's average high is around 81 degrees.
Wednesday, even cooler air will settle in with even better chances for showers around the metro area, through Fort Collins, Greeley, Boulder and Castle Rock. High temperatures, in fact, will be in the middle 70s for the middle of the week.
Thursday will be the coolest day of the week more chances for rain and temperatures dipping 20 degrees below average. The last time Denver saw highs in the upper 50s and low 60s was nearly four months ago on May 19.
Once this final system moves out, drier weather is expected for Friday and the weekend. Highs will also warm back up to average, into the middle 70s and low 80s.
