Another 80° October day is in the books for most of the Denver Metro area. It was Boulder's record-setting 140th of 2026. DIA looks to have come up just a bit shy. #Denver #Fall #colorado #Augtober #COWx

This Week in Colorado Weather: Did Last Week's Storm Change the Drought Picture? 🌧️🤔 In this week’s update, we look at the drought-improving impacts of last week’s storm, why the San Juans are poised to cash in yet again, and whether a late-week cold front can squeeze out a little bit of rain for us before temperatures finally start feeling a bit more like October: bouldercast.com/this-week-in… #COwx #Colorado #denver #weather

FREEZE WARNING THURSDAY NIGHT This is your final reminder to make the necessary precautions for a light to locally hard freeze tonight. Temperatures are forecast to bottom out between 28 and 33° across the area. Drain above ground pipes, disconnect hoses, harvest veggies, and protect sensitive plants. It's beautiful out right now in Denver, albeit a tad chilly. Get at it! #COwx #denver #weather
