It’s been quite a long time since our last measurable precipitation in the Front Range, but that will change abruptly this weekend with the arrival of our next autumn storm system. Unfortunately the slow-moving low pressure will dive too far south into Arizona, largely fizzling out before ever reaching northeast Colorado. Nonetheless, it will bring a bit of rain, snow and much colder temperatures to our area for a few days. Read on for our latest thoughts on how the unsettled weekend ahead will play out. We also briefly review the entries to our 2024 First Snowfall Contest with predictions actually trending towards a later date than Boulder’s climatology would suggest (color us shocked!). There will indeed be some snowflakes in our forecast domain this weekend, but Boulder is not expected to see accumulating snow.

The Front Range will unfortunately see a continuation of unseasonably warm and bone dry weather this week. With a strong ridge of high pressure parked over the region, temperatures will remain summer-like in the lower 80s for the most part. While a couple of weak cold fronts may bring slight temperature drops, there will not be any precipitation. Wildfire smoke from neighboring states will intermittently affect our air quality. We also look ahead to a pattern shift next week which should bring welcomed changes. Read on for all the details.
Colorado Forecast Update: There’s still no clear-cut end to our relentless warm & dry spell in sight
The Front Range is experiencing an exceptionally quiet and warm early autumn weather pattern that is expected to persist through the weekend and into next week. This prolonged dry spell is due to a stubborn ridge of high pressure over the southwestern United States, preventing any significant weather systems from reaching Colorado. Despite a couple of weak cold fronts, temperatures will remain well above normal throughout the extended, with record highs possible on Saturday. Unfortunately, there is no significant rain or snow in the pipeline, exacerbating the ongoing drought and increasing fire danger across the region. Here’s the latest on what is becoming a dire situation.

*Sorry but the contest is now closed to entries*
September was an exceptionally warm month in the Front Range, with most areas landing more than four degrees above average. This was our fourth consecutive month that finished on the north side of normal. Outside of a single soaking rain event, the month was also extremely dry with drought expanding further across the area. Here’s a quick and colorful graphical recap of our weather during September and how it relates to climatology.
This week’s weather will once again be excruciatingly quiet in the Front Range. It’ll be a roller-coaster ride in temperatures from the 70s to around 90 degrees, but no rain is in the forecast as high pressure ridging keeps things totally dry. Two dry cold fronts will pass through the area — one on Monday and another later in the week, but this won’t prevent us from nearing record heat on Wednesday. We also discuss the potential for tropical development in the days ahead and take a look at the devastating aftermath of Hurricane Helene in North Carolina.
The Front Range experienced its first significant rainfall in five months, with some areas receiving up to an inch of rain over the weekend. The start of the work week will be relatively cool. However, a strong ridge pattern known as an omega block will bring warm and dry conditions from Wednesday onwards, with temperatures rising into the 80s and potentially reaching record highs by Thursday. While there is no hope for any snow in our forecast yet, our 10th Annual First Snow Contest will open to entries later this week. Read on for all the details.
