March's snowstorm is on track to sweep across the Front Range in perhaps the heaviest metro Denver snowstorm in the past three years. For Thursday's big change he will be integrating three systems.
The first small system brought snow to the mountains and showers and thunderstorms across the plains.
The second system will bring very strong upslope winds from the northeast Wednesday night into Thursday. At the same time, a deep trough of low pressure cuts into the southwestern United States, pushing moisture from the Gulf of California and Pacific Ocean into southern Colorado.
Thursday is the first warning weather day for heavy snow across the Denver metro area. The Denver metro area could see 10 to 20 inches of snow. One to four feet of snow is possible in the foothills of the Front Range and in and near Palmer's Divide. A winter storm warning is in effect until early Friday morning.
Driving in the Denver metropolitan area will be extremely difficult Thursday and nearly impossible in and near the foothills into Friday morning. Avoid traveling if you can avoid Thursday.
Multiple warnings and advisories for heavy snow have also been issued in the southern region of the state. Colorado Springs and Pueblo could see 4 to 15 inches and 3 to 10 inches of snow, respectively. Southern mountains could see 1 to 2 feet of snow.
