Premium Storm Update – Fri 03/06/25 8:00 AM | Wet snow totals nudged a tad across the board, but impacts remain relatively unchanged

Good Friday morning! Our sloppy March snowmaker is fully underway, and it wasted no time getting the Foothills involved. Snow has been stacking up overnight from Boulder Canyon north into Larimer County, with reports pushing 7 inches near Estes Park before sunrise. That shield of steady snow is now spilling downslope into the Denver Metro area after a brief rain/snow …

Premium BoulderCAST Daily – Wed 03/04/26 | A pair of gorgeous days preceding a cold & snowy Friday

Yesterday’s storm didn’t quite behave the way most guidance suggested. Instead of the bullseye landing up along the Wyoming border, the heaviest rain actually set up well south of Denver—down toward Colorado Springs and Pueblo—where a healthy 0.40" to 1.00" fell. Forecasts for those areas had been pretty modest, so that shift was a notable surprise. Meanwhile, despite the gloomy …

Premium BoulderCAST Daily – Tue 03/03/26 | Storm #1 spreads rain in today, while Storm #2 remains on-track to produce snow later this week

The first of two shortwaves lined up for the Front Range this week is already knocking on the door today, sliding in through this evening with an early‑March mix: rain for the lower elevations and snow for the higher Foothills and Mountains. This morning’s GOES-East water vapor loop shows that compact little mid‑level low spinning neatly over far northwest Colorado—this …

Premium This Weekend in Colorado Weather: Warm & gusty fire danger ahead of a somewhat uncertain weekend cold front

The upper‑level jet remains over the region, but its subtle slide south overnight tugged the Pacific moisture plume with it. In its wake, much drier mid‑level air has spilled into northern Colorado, and that’s the air mass we’ll be tapping into today and Friday as daytime mixing deepens. It’s a classic setup for elevated fire danger: dry air aloft, stronger …

Premium BoulderCAST Daily – Wed 02/25/26 | The Front Range stays warm, windy and fire-prone for several more days

The dominant storyline today — and really through the end of the week — remains the anomalous warmth, persistent wind, and elevated fire danger as a strong Pacific jet streak stays draped across northern Colorado. The jet is the engine behind everything: the mountain snow, the downslope winds, the mixing, and the fire weather concerns. Mountain Snow & High‑Country Instability …

Premium BoulderCAST Daily – Tue 02/24/26 | High winds, critical fire danger, and Mountain snow develop as a Pacific jet drops south

Good Tuesday morning, everyone! We’re staring down another remarkably active weather day across Colorado — almost a carbon copy of what unfolded exactly one week ago. A moisture‑rich Pacific jet streak is sagging south into the state, energizing the atmosphere and setting the stage for a multi‑hazard day. Four major components define today’s forecast, each interacting with the others in …

This Week in Colorado Weather: February 23, 2026

As February limps toward the finish line, Colorado’s “winter” continues to behave like anything but. Last week the Mountains cashed in on a burst of Pacific moisture while the Denver Metro area stayed stubbornly snow‑starved. The week ahead brings more of that same split personality—warmth, wind, fire danger, and another round of Mountain snow. We break down the lopsided snow totals from last week, the updated but still troubling snowpack numbers, and discuss why this week will be so darn warm and windy again in the Front Range.
