With record-challenging heat to start and a dramatic cooldown looming midweek, Colorado’s weather is shifting gears—and fast. A powerful ridge is driving us toward 100° on Monday, but it won’t stick around. By midweek, cooler temperatures and increased rain chances roll in, possibly delivering relief via much-needed moisture. We break down the evolving setup, the timing of the incoming cold front, and what it could mean for rainfall totals, flash flooding risk, and your week ahead.

After a hot and mostly dry Monday, the Front Range is in store for a wetter stretch midweek, with an uptick in monsoonal moisture and storm activity. A favorable upper-air pattern and midweek cold front will drive daily thunderstorm chances and potential flash flooding, especially Tuesday through Thursday. Conditions will trend hotter and drier into the weekend and next week, exacerbating the ongoing drought and fire risk in the High Country.

Monsoon season may have officially started earlier this month, but it’s off to a sluggish and lack-luster beginning across Colorado. Boulder has seen frequent storms—yet little meaningful rain—and wildfire smoke from the Western Slope and neighboring states is starting to pool to our west. A cold front arriving Tuesday night will bring cooler temps and a bump in thunderstorm chances for Wednesday, followed by a promising shift toward a more classic monsoonal setup Thursday through the weekend ahead with continued daily storms. This week, we’re tracking some heat, smoky haze, and hopefully, a few solid soakings of rain.
Wednesday brought historic heat across the Front Range, with Boulder hitting a record high of 101°F—the city’s hottest day in over a decade. A weak cold front has since cooled things off slightly, ushering in a good chance of storms the next few days as well. Sunday into Monday turn drier and hotter again as reverse monsoonal flow sets up, potentially stifling our typical summer storm pattern for a bit.
It’s going to be a scorcher across the Front Range this week—with temperatures climbing fast and flirting with triple digits by midweek. But just as the heat peaks, a pattern shift arrives that will bring cooler weather and a chance of storms again by Friday. Read on for all our full outlook of the weather week ahead.
