Sure…it has been fairly smoky already this week across our area, but it’s about to get a whole lot worse! An extremely smoke-laden airmass is poised to invade the entire state of Colorado late Friday night. The cause? An upstream low pressure system has been hard at work gathering up literally ALL the smoke from massive wildfires burning in California, the Pacific Northwest and southern British Columbia…and guess what? That low pressure system is headed our way!

After more than two consecutive weeks of hot weather, the pattern is set to shift following the passage of a welcomed cold front Friday evening! While not directly tied to the monsoon, storm chances will ramp up considerably in the near-term. Unfortunately, at the same time weak winds aloft under high pressure will introduce a real risk of flash flooding over the next few days with recent wildfire burn scars at the highest risk (Calwood, Cameron Peak, etc.). We discuss some historical context for July’s weather so far, when the cold front will arrive, how chilly it will be the next few days, and expected rainfall totals by the end of the weekend across the Front Range.
June 2021 began as one of the hottest and driest on record for the area, but ended on a cool and rainy note! Other weather highlights during the month included a slew of new wildfires across the Western Slope, a highly photogenic landspout tornado, multiple heatwaves, and poor air quality from near and distant wildfires. Here’s a quick and colorful recap of our weather during June and how it relates to climatology.
As the heatwave reaches peak intensity on Wednesday, Boulder is well-positioned to obliterate the existing daily record high temperature for the date, maybe even before the lunch hour! However, increasing smoke from distant wildfires, more widespread clouds and outflows from developing showers could keep the city from hitting the elusive century mark. We review the climatology of rare triple digit heat, discuss why Denver is often several degrees warmer than Boulder on days like this, and take a look ahead to when the heat will end.
Front Range weather during the month of May was certainly busy! We got our first taste of summertime thunderstorms, including accumulating hail in spots. There were numerous upslope storms; a few even turned cold enough for snow in Boulder and Denver. La Niña dissipated and the drought showed continued signs of improvement. Here’s a quick and colorful rundown of our weather during May 2021, the notable atmospheric highlights and how it all relates to climatology.
The weather for Memorial Day Weekend will not be pleasant across the Front Range unfortunately. A cold front is set to arrive early Saturday paving the way for a relatively cold and gloomy holiday weekend. Will the weekend be a total washout? How much rain can the area expect? When and where will a little snow mix in? Read on to find out!
Anywhere from 0.5 to 1.5″ of liquid fell across the Front Range in the past few days, including up to 15″ of snow in the Foothills. There was also some accumulating snow across the lower elevations, too. Let’s take a look at the snow totals from the last few days!
Our weather during the month of April was very fickle. Eleven consecutive warm days kicked off the month but were quickly followed by a prolonged period of cold and snow on the heels of several Arctic outbreaks. The important result, however, was a significant improvement in the drought across northeast Colorado. Here’s a quick and colorful rundown of our weather during April 2021 and how it relates to climatology.
