The Front Range is heading into a stretch of intense summer heat this week, with a dominant high-pressure system set to lock Colorado into several days of sizzling temperatures and dry skies. Expect highs in the mid to upper 90s every day through Friday. While Boulder isn’t guaranteed to break any record high temperatures, past patterns suggest we could run hotter than models are currently predicting—something worth watching as it would bump up the heat risks in the Metro area. Relief is on the horizon, though: a cold front late Friday should bring a sharp cooldown just in time for the weekend with at least low-end chances for storms returning.

Colorado’s monsoon season has been off to a sluggish start, and the latest surge storm potential this week isn’t even from the monsoon itself—it’s thanks to potent cold fronts dropping in from the northeast. In today’s update, we dig into why flash flooding is on the rise this week, which areas are most at risk, and what the next few days could mean for our thirsty landscapes. Spoiler: while heavy rain is possible, it’s only a short window and many of us won’t see it. Plus, the new blanket of wildfire smoke is likely to stick around through the weekend.
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.
Wednesday may have felt underwhelming across the lower elevations of the Front Range, where lingering low clouds kept things calm and cool for much of the day — but just west of Boulder, up in the sunshine-soaked Foothills, something rare and striking took shape Wednesday afternoon. A graceful funnel cloud twisted above the mountain peaks in a spot where such phenomena almost never occur. We explore why tornadoes (and their funnel-shaped precursors) are so uncommon in Colorado’s higher terrain, and take a closer look at what makes broader Boulder County particularly adverse to tornado development.
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.
