Models are hinting at a moderate storm for the highest elevations of Colorado (Above 9,000 feet) late Wednesday/Thursday shifting south towards the 4 corners and New Mexico Thursday PM and Friday. New data is changing with each run but here is the quick run down on what appears to be a moderate event.
Light snow showers should break out above 10,000 feet early Wednesday over the San Juans and move towards the continental divide of the northern and central mountains early Thursday (Before daybreak). Snow should intensify Thursday under Northerly flow (Winter Park, Berthoud Pass, Loveland, Keystone, Eldora-wildcard). Some snow will spill west of Summit County with brief periods of NW flow (Good for Vail but short lived). Most snow will be confined to the areas closest to the Front Range of Denver. High snow levels Wednesday night (9-10,000 feet ) drop on Thursday to 6,000 feet with a weak cold front. Snow water ratios will be high with perhaps 1/2 to 1 inch of water only producing 4-9 inches of snow. Warm temperatures and dense snow (might be mixed with rain early Wednesday evening) could provide the needed layer below frozen “mank”. Snow quality will increase slightly on Thursday. Powder watch will be for areas from Summit County and northeast through Berthoud Pass and Rocky Mountain National Park through Thursday (Above 9,000 feet). Areas near and East of the Eisenhower Tunnel might do best. Light snow will linger into Friday morning. Totals generally in the 4-7 inch range with some higher amounts with terrain above 10,000 feet and East of the Divide.
Moisture tap from the Baja intensifies snowfall over the southern Rockies on Thursday PM and Friday. Areas towards Pikes Peak and the Eastern San Juans might nab 7-11 inches or more! Wolf Creek would deserve watching however wind direction not favorable! Some surprises could develop Thursday night. Models point to heavy snow at the highest peaks of New Mexico under Northeast winds late Thursday and Friday. That might favor points from Taos and East. While moisture paints a bullseye from Taos and Santa Fe wind direction may favor resorts that benefit from Easterly flow. Perhaps 3-7 at Taos and higher amounts to the East and south?
Even spots in Northern Arizona above 8,000 feet will see snowfall primarily Wednesday/Thursday (Light amounts).
