Typical Colorado March weather was observed on Saturday...March 24th. During the time that heavy snow was affecting the Colorado Northern and Central Mountains, severe thunderstorms with tornadoes developed across northeast Colorado. While the Denver/Boulder Forecast Office was concentrating on the snow warnings, advisories, and the snow conditions for the foothills and the mountains west of Denver, suddenly severe thunderstorms with multi-vortex tornadoes developed over Philipps and Sedgwick counties. Although the tornadoes were short lived and were generally weak, they skipped around the area causing alarm for the residents of the 2 counties. After about an hour or so, the storms moved into Nebraska. So simultaneously...a winter weather warning was in affect for the northern and central mountains, a snow advisory had been issued for the foothills west of Denver, and a tornado warning was issued for Philipps and Sedgwick counties...a situation which can definitely occur during springtime in Colorado.
