By Wednesday morning, rain totals included 2.04 inches in Durango, 1.71 inches in Silverton, 1.37 inches in Golden and 1.25 inches in Boulder. Arvada had received 1.14 inches, while Denver recorded 0.38 inches.

Rain and mountain snow were expected to become more widespread Wednesday afternoon and continue into the night. Highs across much of the Denver area were forecast to remain in the 40s.

Snow levels are expected to fall to about 7,000 feet by Thursday morning. The heaviest accumulation is forecast above 9,000 to 10,000 feet, where higher mountain elevations could receive 4 to 12 inches. Mountain valleys and higher foothills may see lighter amounts, including a dusting in some locations.

A Winter Weather Advisory is in effect for the mountains from Wednesday afternoon through Thursday morning. Snow and potentially slick roads could affect mountain travel during that period, particularly for drivers crossing passes. Rain may also persist along the Interstate 25 corridor and eastern plains Thursday morning before precipitation tapers off in the afternoon as the storm moves east.

The colder air could bring temperatures to freezing or below across much of the eastern plains late Thursday night into early Friday. A Freeze Warning is in effect for the San Luis Valley from midnight Wednesday through Thursday morning, where temperatures could fall into the mid-20s to low 30s. El Paso and Kiowa counties are under a Freeze Watch for Thursday night into Friday morning, with lows forecast in the upper 20s to low 30s.

Residents with sensitive plants or exposed plumbing may want to prepare for freezing temperatures. The cold spell is expected to be brief: skies should begin clearing Friday, followed by a mostly dry weekend and a gradual return to above-seasonal temperatures.
