Don’t count winter out yet
March 18, 2012
Although the official start of spring is only days away, Summit County is accustomed to at least a few extra weeks, and sometimes months, of unofficial winter.
But the 2011-12 season has been unusually dry and now weather forecasters say it’s unclear whether Summit County will get the spring snowstorms that traditionally supply local resorts with powder through April and sustain Arapahoe Basin into the summer.
Summit County could get its first dusting of fresh snow in more than a week tonight, but the storm doesn’t have much potential for moisture and is expected to clear out by mid-week, according to forecasts from the National Weather Service in Boulder.
“Historically, you can still get a big storm through March and even through April, so there’s still the potential there,” NWS meteorologist Scott Entrekin said. “But at least after this first (system) moves across, there’s not much going on. … The later (in the year) it gets, the less chance there is of getting any significant snow.”
March is usually one of the snowiest months of the year for Summit County. This year, it was expected to help make up for the lack of snowfall in the early season.
But a resurgence of precipitation in January and February has ended, and, halfway through, March has produced only 6 inches of snow for Breckenridge.
