Our scorching hot, two-week-long heatwave will finally come to an end later this week, but not before we endure a few more days. A cold front is slated to arrive into the Denver area late Wednesday finally knocking us out of the 90s. This front will also come with an enhanced chance of rainfall, though monsoon moisture is still largely lacking. Despite daily chances for rain this week, our existing fires will continue to smolder and the risk of new fire ignitions remains uncomfortably high.

Between the extreme heat, thick smoke and new wildfire ignitions, this week has been quite the disaster in the Front Range! Our fuels have been primed for weeks now and our team has been vocal regarding this inevitable outcome, but things unravelled much quicker than even we expected this week with something like ten wildland fires in the Front Range just since Monday, in total burning more than 9,000 acres of forest! The weekend unfortunately won’t offer much reprieve from the heat, fire or drought, but we are tracking a potential shift next week towards wetter and cooler conditions. We provide an update on the local fires, the ongoing heatwave, the widespread smoke, and when actual raindrops may return to the forecast.

Fortunately, as of last Friday afternoon, the wildfire smoke from Canada has cleared out of our area. However, this week will feature new weather challenges in Colorado, with the primary story being a brutally hot, dry and extended heatwave, with a secondary concern being the return of thicker smoke later in the week. Let’s take a look!

After days of scorching heat, this week will fortunately trend cooler and wetter with the return of monsoon moisture to Colorado — perfect timing considering severe drought has now returned to the area and fire danger continues to explode. Following one more toasty outing on Monday, temperatures will tumble below normal by midweek with daily chances for monsoon thunderstorms, some of which could be severe. We review the ongoing heatwave, the recent Dinosaur Fire in Boulder, why the pattern is now shifting and look ahead to which days will offer the best chance of rain this week.
An impending pattern shift is expected to bring record-breaking triple-digit temperatures to the Front Range this weekend. This latest round of extreme heat is due to a superheated airmass moving into Colorado from the Desert, an airmass which has already produced all-time record highs in other western states. We review the climatology for rare triple digit heat, discuss why Denver is often several degrees warmer than Boulder during the summer, go over the forecast for just how hot it will get this weekend and look ahead to when we may finally cool off.
