Moderating Temperatures for the East; Developing Storm for the Plains

Temperatures will continue to moderate across the east half of the nation through at least the first half of this week. A developing storm across the Southern Plains may bring some heavy rain from the Plains to the lower Great Lakes region, a wintry mixture and accumulating snow across the Midwest and Upper Mississippi Valley into mid-week. The west remains unsettled with occasional rain and snow. Read More >

Overview

A large and unseasonably moist low pressure system lifted across the Four Corners region March 18-20. Favorable southerly flow during the onset of the event produced moderate to heavy snow over the southern mountains and some southwest Colorado valleys. Once cooler air moved into the region during the latter half of the storm, snowfall began to favor the northern and central Colorado mountains. By the end of the event, generally 12 to 20 inches of snow fell over the Southwest San Juan Mountains with 3 to 8 inches across the Northwest San Juans. The Animas River Basin saw an average of 7 to 11 inches of snow while the San Juan River Basin received 6 to 7 inches. The Uncompahgre Plateau saw locally high amounts of up to 27 inches while portions of the west-central Colorado mountains saw 8 to 11 inches. In eastern Utah, the La Sal and Abajo Mountains received an average of 12 to 19 inches of snow.

In addition to heavy snow, wind gusts exceeded 45 MPH at times.
