Big changes will begin to arrive as soon as Tuesday for the Front Range. A large developing trough across the west will begin to move into Colorado later Tuesday afternoon. Storm chances will increase Tuesday afternoon in the high country, and these thunderstorms will spread onto the I-25 corridor late Tuesday afternoon and into Tuesday evening. The associated cold front will allow temperatures to cool to some of the coolest levels we have seen in months. The chilliest day looks to be Thursday. Some of the rainfall may be heavy at times. This heavy rain will bring in the concern for flash flooding. Rain will continue off and on through Thursday, but the weather will dry out and warm up for the upcoming weekend.
Colorado Springs: 30% chance for storms in the afternoon, high 85
Pueblo: 20% chance for an afternoon storm, high 93
Monument: 40% chance for an afternoon storm, high 81
Teller County: 50% chance for storms, high 74
