Warm, gusty weather is kicking off the first full week of 2026, but the atmosphere has a few twists lined up as we move toward the weekend. A stubborn ridge will keep us mild early on as downslope winds ramp up fire concerns. However, a developing trough later in the week will turn us much colder — with even the possibility of snow for Boulder and Denver if the storm track cooperates. The details are still evolving, but there’s plenty to watch in the days ahead.
