The shortened work week arrives with a bit of a plot twist as Tropical Storm Marie sends a surge of deeper moisture straight into Colorado. That boost will keep scattered storm chances alive through Tuesday before a midweek cold front briefly dries us out and knocks temperatures back into more comfortable territory. But the break won’t last — late‑week heat is set to rebuild quickly, and weekend guidance is already hinting at yet another unsettled pattern trying to form, with a fresh plume of subtropical moisture lurking on the horizon. This summer’s stubborn, underperforming monsoon looks determined to limp well into September. Read on as we unpack the setup and what it will mean for weather along the Front Range this week.

The posts contain discussion of severe weather in our region, including forecasts, outlooks, and recaps of events involving large hail, damaging winds, and tornadoes.
After more than a week of relentless heat, the Front Range is finally heading into a pattern change — but not before we break a few records and squeeze out one more day near 100°. This week will bring a notable shift: true monsoon moisture is poised to surge over the Continental Divide, storm chances finally return and temperatures finally ease… at least for a moment. We break down what’s driving this stubborn heat, when the storms arrive, and why flash-flood concerns may quickly replace heat and fire danger as Colorado’s primary weather story.
June 2026 closed out as a parched, smoky, and somewhat warm month across the Front Range, with Boulder seeing almost no meaningful moisture aside from a few late‑month storms — some of which dumped large hail across portions of the Denver Metro area. Day after day, smoke‑laden skies from both distant and eventually in‑state wildfires muted visibility and degraded air quality, a stark reminder of how the West’s exceptionally warm, snow‑deficient winter is now echoing across the region in the form of early‑season fire activity and persistent haze.
Here’s a graphical look at how June 2026 unfolded across Boulder, Denver, and the Front Range — and how it compared to climatology.
The atmosphere is gearing up for one of those classic late‑June stretches where Colorado tries to run every weather storyline at once. Several days of unusually strong flow aloft, deepening upslope moisture, and a parade of shortwaves are about to collide over the Front Range. The result will be day after day of severe thunderstorms. Add in waves of incoming wildfire smoke and a potentially high‑end fire danger setup by the weekend, and there’s plenty to unpack in this week’s forecast. Let’s take a closer look.
Warmth, wind, and a few atmospheric curveballs are lining up for the Front Range this week — and it all starts with a sharp swing from severe storms to hot fire danger in less than 24 hours. From Monday’s hail‑ready instability to mid‑week blow‑dryer conditions and a potential cool‑down lurking on the weekend horizon, this week’s forecast has a little bit of everything. Read on as we detail what to watch as this surprisingly active June pattern unfolds across Colorado.
