After months of drought, the Front Range is finally cashing in on a meaningful storm, with Boulder already topping an inch of rain and more moisture still to come. But are the best rains already behind us? A closer look at the storm’s evolving track suggests the answer may be yes, while a hard freeze waits on the other side of this long-overdue autumn gloom.
After months of watching drought deepen across the Front Range, Colorado is finally getting a storm that could turn the tide. A slow-moving upper low will tap into an unusually rich plume of subtropical moisture and bring widespread rain to much of northern Colorado, along with the season’s first meaningful Mountain snowfall. How much rain can Boulder and Denver expect, who stands the best chance of topping an inch, how low will snow levels drop during the event and which night will bring the season’s first freeze? We break down the latest forecast, timing, rainfall totals, and snow prospects.
After one final taste of summer warmth on Monday, the weather pattern across Colorado is about to undergo a dramatic shift. A much colder and wetter setup is taking aim at the Front Range this week, with rain returning to the forecast, accumulating snow in the Mountains, and perhaps our first real frost threat of the season by week’s end. While we’ve seen promising storm systems fizzle already this fall, the data continues to suggest this one has a better chance of delivering. We break down the timing of the cooldown, what the latest ensemble guidance says about rainfall totals, and why Friday and Saturday mornings will bear watching for frost.
