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.
One soaking rainstorm, zero snowflakes and Boulder’s 17th straight warmer-than-normal month. Our October 2026 Climate Review breaks it all down, plus a look at how 2026 is well on-track to be the warmest year in Colorado history.
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.
