September 2, 2021 / BoulderCAST Team

August 2021 across the Front Range was defined by its poor air quality and tenacious smoky skies which were mostly caused by out-of-state wildfires. Other weather highlights during the month included a rotating thunderstorm which prompted tornado sirens, lots of red smoky sunsets, a sprinkle of summertime snow in the Mountains, and the landfall of Category 4 Hurricane Ida sixteen years to the day after Hurricane Katrina. Here’s a quick and colorful recap of our weather during August and how it relates to climatology.

The focus for this week’s weather discussion lies in the tropics. Category 4 Hurricane Ida made landfall into Louisiana on Sunday, but more importantly for Colorado, the remnants of once Hurricane Nora in the Pacific will reach our neck of the woods later this week. What will this surge of tropical moisture bring to the Front Range and when do we expect the thick smoke to begin to clear out again? Read on to find out.

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.

This week will feature a continuation of the dangerous, unprecedented heatwave in the Pacific Northwest, but cool and rainy weather in the Front Range. Go figure! Our temperatures will remain below normal through the week with daily chances for showers and thunderstorms, helping to alleviate but not remove wildfire concerns across the state. We also discuss the status of monsoon season, the active tropical eastern Pacific, and what may lie ahead for the Fourth of July weekend.

Following the long, cold and gloomy holiday weekend, our weather improves considerably in the coming days. Temperatures will warm back above average and may even approach 90 degrees for the first time in 2021. After a few dry days, subtropical moisture is expected to surge into Colorado during the upcoming weekend bringing the return of wet weather to the region.

Summer 2021 Outlook: La Niña is dead, but that may not necessarily bode well for Colorado’s drought or the fire season ahead

May 18, 2021 / Ben Castellani

There’s no doubt about it. The La Niña pattern that developed late last summer is now dead. There’s no need to mourn this loss as this is actually good for Colorado and bodes well for a more active monsoon season this summer…or does it? Let’s take a look at the current state of ENSO and the weather outlook for the coming months.
