Get ready, Colorado! The first snowflakes and a hard freeze of the season are on their way as this dramatic shift in weather across the state continues. Better late than never, right? We discuss when the snow will begin, how much could stick on the grassy surfaces, and when to expect the end to the 2024 growing season as temperatures are sure to plummet below freezing. We’re also tracking another potential snow event early next week. Here’s the latest.
As we transition deeper into autumn season, Colorado weather continues to keep us all on our toes. This past weekend, a slow-moving storm system that was expected to bring widespread light precipitation to the Denver Metro area ended up being a tad underwhelming, with the bulk of the moisture staying to our south. While Boulder and Denver received only minimal rainfall, areas of southern Colorado and New Mexico experienced heavy rainfall which led to deadly flash flooding. Looking ahead, this week promises relatively quiet weather for the Front Range, with just a brief cool down scheduled for late week. We’re also tracking an interesting storm in the pipeline for next week which could bring sub-freezing temperatures and potentially some snow to the area just in time for Halloween.
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.
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.
