On Wednesday a cold front and associated deep midlevel trough passed across the West. This system caused around 1/2 foot of snow fell at middle and higher elevations in the northern West yesterday, and up to a foot of snow fell at high elevations in the Wasatch Range. At lower elevations, one-half to 1 inch of rain fell.
Due to the ground's being warm, not much of yesterday's snow remained on the ground, but cool temperatures expected over the next few days will retard snowmelt. The recent snowfall in central Colorado continued, but not to the rapid degree it had in the past few days due to the cold front passage.
Up to 1/2 foot of snow is possible in and around the Black Hills today near the surface low and sufficiently-cold surface air. Isolated light snow will be possible due to low-level and midlevel troughing across the Central Rockies today, too.
A cold front and deep midlevel trough will move quickly into the Northwest and spread across much of the West by early next week. A disturbance leading and later becoming incorporated into this trough will pass across the northern West late this week and early next. Up to 1/2 foot of snow is likely in the higher-elevation Intermountains on Saturday, and up to a foot is possible in the Northern Rockies and nearby High Plains ranges on Sunday as the system acquires better moisture.
