Premium BoulderCAST Daily – Fri 11/06/26 | A Cloudy End to the Week But Mild Temps Stay Strong

Aweak area of low pressure across Arizona brings cloud cover and some weak showers to the state into this afternoon. A weak shear axis is also present from Wyoming into southeast Utah. The low pressure system will drift to the south of Colorado today, but enough convergence and thereby lift will support some light snow showers over the higher terrain. …

A Personal Goodbye to the American NAM Model, Retired After 20 Years

The weather world lost a small piece of its history this week with the sunset of the American NAM model. Coincidentally, this model and my meteorology career started almost exactly the same time in 2006. Since then, both have been on quite a journey. While technology marches forward and better models take its place, it’s impossible not to reflect on the role this one played, not just in forecasting, but in shaping the career of countless meteorologists, myself included.

Premium BoulderCAST Daily – Tue 11/03/26 | Drying Out Across Boulder and Denver as Sunshine Returns

The stubborn closed upper low that has been responsible for several days of unsettled weather and historic flooding across the Southwest is finally pulling away from the region. As of Tuesday morning, the center of circulation is located over central Kansas, though just enough wrap-around moisture remains on the backside of the system to generate a few isolated rain showers …

This Week in Colorado Weather: November 2, 2026

Parts of southwest Colorado have picked up 15 to 20 inches of rain in the last 60 days, and this weekend’s storm pushed rivers across the Four Corners to historic levels with devastating results. Here on the Front Range, southwest flow kept us mostly dry again, with Sunday evening’s showers adding up to about a tenth of an inch.

The colder back half of that storm reaches us Monday. A cold front moving through this morning brings our best chance of rain from this system, though some parts of the Denver area are better positioned than others. Snow is on the way for the high country, temperatures will below normal, and another storm is approaching later this week. Here’s what to expect.
