Snow and cold helped crews make progress on a northern Colorado wildfire that has destroyed about 15 homes, but a federal team that took over operations Monday was bracing for warmer, windier weather. Roughly 200 firefighters were battling the 5-square-mile blaze about 15 miles west of Fort Collins. Two helicopters dumped water from nearby Horsetooth Reservoir and planes helped pinpoint hot spots in the hilly, rugged terrain.
