A Pacific storm is expected to move over the region beginning
late Friday night, continuing through Saturday night when the
highest precipitation rates are expected...snow then lingers over
the Colorado mountains into Sunday. Latest model guidance
indicated that the storm will arrive later than previously

The early phase of the storm will feature warm southwesterly flow
ahead of its associated cold front. This will keep snow levels
elevated from around 7500 to 8500 feet through Saturday afternoon
limiting snowfall to the mountains.

Models are now consistent in bringing the cold front west to east
across the forecast area Saturday night. This should be the most
active period of the storm. As colder air filters into the area
behind the front expect snow levels to lower to the valley

Potential snow accumulations in the valleys are expected to be
fairly light with just 1 to 2 inches in the lower valleys and from
2 to 4 inches in the higher valleys. Potential snowfall
accumulations 6 to 12 inches are expected across the mountains
with higher accumulations for areas above 11,000 feet.

Stay tuned to NOAA Weather Radio or local media reports regarding
this developing winter storm.
