Premium Storm Update – Thu 04/30/26 8:00AM | A soggy Thursday with rain and Foothills snow, though totals have continued to trend down

Rain is spreading across eastern Colorado this morning, with a broad, soggy setup still on track to bring rain and high‑elevation snow through the day to the Front Range. However, a continued southward shift in the storm track means precipitation totals around Denver and Boulder will likely fall short of earlier expectations. Nonetheless, a cool, gloomy day with plenty of showers still lies ahead, along with accumulating snow in the Foothills. Here’s the latest.

Premium BoulderCAST Daily – Tue 04/28/26 | Staying cool with a couple showers, the late-week storm is still the main event despite trending south

Moderate, moisture‑rich west–southwest flow is hammering into Colorado this morning, and GOES‑East water vapor imagery clearly highlights our second shortwave of the week racing toward the Front Range, now centered near Salt Lake City. That embedded disturbance will continue sliding east through the day, pushing east of Denver by early evening. As it departs, large‑scale ascent fades and rain chances …

Premium This Weekend in Colorado Weather: Short-term fire concerns spike ahead of a wetter weekend

Despite the overnight cold frontal passage—and a roughly 20°F drop from yesterday’s lower‑80s highs—the synoptic‑scale pattern driving our weather remains largely unchanged. Critical fire‑weather conditions continue across eastern Colorado as very dry boundary‑layer air and persistent gusty winds remain in place. A weak mountain‑wave event is unfolding early this morning across the Foothills and adjacent cities. A swath of moderate …

Premium BoulderCAST Daily – Wed 04/22/26 | The Front Range braces for back‑to‑back critical fire weather days

Critical to locally very critical fire danger will dominate the Front Range today and again tomorrow as an exceptionally dry downslope regime takes hold across our drought‑stressed state for the next 36+ hours. A disorganized trough is currently draped over the Pacific Northwest. This feature will lift east‑northeast through Thursday, keeping nearly all meaningful precipitation north of Colorado aside from …

Premium BoulderCAST Daily – Tue 04/21/26 | Quiet sunshine today, critical to locally extreme fire danger on Wednesday

Today delivers another warm, sunny, and remarkably quiet setup along the Front Range as we remain positioned beneath the stabilizing influence of a modest shortwave ridge axis. Colorado woke up essentially cloud‑free, and that largely pristine sky cover will persist through most of the daylight hours. The only real change arrives late: a narrow plume of upper‑level Pacific moisture, clearly …

This Week in Colorado Weather: April 20, 2026

The atmosphere is gearing up for a dramatic mid‑week pivot, and the Front Range is about to feel every bit of it. We start the week under a warm, bone‑dry ridge that will send temperatures soaring and fire danger spiking—especially by Wednesday, when downslope winds and exceptional dryness are set to collide. But just as quickly, the pattern will flip. A pair of incoming troughs will drag us into a cooler, unsettled stretch of weather heading into the weekend, with several chances for much‑needed moisture and even the prospect of a few snowflakes mixing in at times. It’s a true tale of two patterns this week! Read on for all the details.
