DENVER (AP) – If it’s springtime in the Rockies, there must be snow, tornadoes and rain in the forecast. And there are in Colorado.

Tornado watches and warnings have been issued for the Denver area and Eastern Plains through 9 p.m. Tuesday. The National Weather Service says radar indicates the buildup of thunderstorms just northeast of Denver.

National Weather Service Senior Meteorologist Mike Jamski says a tornado touched down in a rural area of Weld County in northern Colorado. Tornado sirens sounded intermittently shortly after 3:30
p.m. in Cheyenne, Wyo.

In Western Colorado, an upper-level, low-pressure system is expected to dump snow at elevations at about 8,000 feet and higher. Snowfall could range from four to eight inches and winds could reach 25 miles an hour.
