High pressure has reclaimed control over the West. Warm, dry air will overspread the region through midweek. The ensuing strong sunshine and a marked day-to-day rise in temperatures will prompt a rapid melt down of snow from last week's snowstorm in the Colorado Rockies. By midweek, very little of the multi-foot snowpack in the area will remain.

Meanwhile, temperatures will soar in the Southwest, vying for a spot in the record books. Over the next couple of days, high temperatures in the region will rise as much as 20 degrees above normal. The mercury will even eclipse the 100 degree mark in parts of southern California and southwestern Arizona.
