Late Season Snow Chances for I-25

WEST - A low-pressure system in the Pacific is expected to move onshore this week, bringing with it an increased chance for rain and snow across the otherwise drought-stricken West. This upper-level low will team up with a surface front as it moves into the Four Corners, increasing snow chances for Colorado from Tuesday night through Wednesday morning.

Rain and snow have already started moving into the Sierra Nevada this Sunday. This isolated-to-scattered moisture will continue to increase from Monday through Wednesday across the Southwest. Models show rain and snow pushing farther inland late Monday. By Tuesday night, temperatures along the I-25 corridor will be much cooler, and snow will begin filling into Colorado.

The National Weather Service office in Denver/Boulder, Colorado, has already started issuing winter storm watches for parts of Colorado and Wyoming beginning Monday night and continuing through Wednesday. Snow totals may reach 4-10 inches, with some higher elevations potentially seeing up to 20 inches.

Here's a look at the snowfall totals we're expecting based on our in-house model. The heaviest totals look to occur around the Continental Divide, which could make for very difficult travel near the Eisenhower Tunnel late Tuesday into Wednesday morning.

For Denver, only 27.3 inches of snow have accumulated so far this season. On average, year-to-date snowfall totals should be around 50 inches. This is much-needed moisture for the Mile High City.
