Summary (tl;dr)

Denver is experiencing a dramatic and rapid shift in weather, transitioning from a period of record-breaking warmth and high fire danger to significantly colder temperatures and an impending snowstorm.

Essential Background

Denver, Colorado, typically faces cold and snowy conditions in January. However, the first half of January 2026 brought unseasonably warm weather, marking the city's warmest start to winter on record, with temperatures frequently exceeding 60 degrees Fahrenheit. This prolonged warm and dry spell contributed to an elevated risk of wildfires across the region.

Following a period of unusual warmth and high winds that triggered Red Flag Warnings and prompted public safety power shutoffs in parts of northern Colorado due to wildfire risk, Denver is now undergoing a swift transition to severe winter weather. As of Sunday morning, January 18, 2026, temperatures have plummeted, with the city experiencing clear skies at 5°F (-15°C), feeling like -2°F (-19°C). A quick-hitting snowstorm is forecast to move into the Denver and Front Range areas late Sunday night into early Monday morning, bringing the potential for brief but intense snowfall with larger, fluffier flakes.
