The storm over the weekend may not have amounted to much, but the front coming through today may drop some significant snow in the mountains.
"In general, the upper elevations will get some snow," said Bryon Lawrence, a meteorologist and hydrologist with the Grand Junction office of the National Weather Service. "There's a strong cold front going through (Monday night), and the snow will shift to primarily the northwest facing slopes. So because of topography, Ouray to Red Mountain Pass will see more snow."
Lawrence said the storm, which was forecast to begin as rain in lower elevations Monday night, will change quickly to snow with the cold front. Durango was expected to receive less than an inch of snow Monday night and to get a similar amount through 6 p.m. today.
Purgatory at Durango Mountain Resort is predicted to receive 6-8 inches by the end of the storm.
Today will be cooler, in the mid-30s for highs in the mountains, with Durango forecast to reach a high of 43 degrees.
"Temperatures will moderate back to the 50s by Wednesday in Durango," Lawrence said. "The mountains will continue to be in the mid-30s for highs, cooler than it has been, which is better for snowpack replenishment."
At 9:30 p.m. Monday, the Colorado Department of Transportation was reporting snow falling on Coal Bank, Molas, Red Mountain and Wolf Creek passes, with roads snowpacked and icy. Coal Bank, Molas and Red Mountain were restricted for all vehicles, with chains, snow tires or four-wheel drive required. Commercial traffic, including buses, was required to use chains on Wolf Creek Pass.
The Colorado Avalanche Information Center has raised to "considerable" the risk of avalanches in the southern San Juan Mountains.
Another storm is predicted to come through the area beginning Thursday and continuing into Friday, but it was too far out for Lawrence to estimate any precipitation.
"It's later in the winter now," he said. "There may be a lot of storms, but they'll generally be in the mountains."
