Snow for 4-6 days for Colorado coming: Whiteout daily snow report, March 20

Wednesday through Saturday — only four more days — of warm temperatures, in-and-out sunshine and scattered snow showers before cooler air and snow return to Colorado’s high country.

Early forecast models call for between 10-30 inches of snow from Sunday to Tuesday, perhaps into Wednesday, as a set of larger scale storms track across the state.

Recap:

On Tuesday, weather around the state was mostly dry and calm, with temperatures in the 30s and low 40s. The high in Vail Village was 39 degrees.

Forecast:

On Wednesday and Thursday, sunny days and potential snow showers nights are forecast for multiple mountain areas around Colorado, mostly focused around the Continental Divide along the Front Range and in the San Juan mountains.

Day time heating will melt and/or evaporate some snowpack accompanied with moisture streaming in from the west coast to form possible pop up snow showers each afternoon. Snow accumulations will be light, however, with a dusting to one inch possible.

On Thursday, a storm clips Colorado from the north, brining similar accumulations to the northern and western mountains, with ski areas and resorts along I-70 perhaps seeing 1-2 inches of snow for Friday’s first chair.

On Friday and Saturday, drier weather and warmer temperatures return ahead of the prolonged storm(s) from Saturday night to Tuesday night/Wednesday morning.

The ECMWF synoptic composite model forecasts a lot of moisture over Colorado Saturday night, just ahead of the colder air to the west. Snow will form into Sunday morning and be heavy at times in the western, northwestern and northern San Juan mountains before all mountain zones begin receiving snow by Sunday afternoon.

Depending on the density of the snow, one inch of water is equivalent to 10 inches of snow based on a common rule of thumb ratio of 10:1. (Weather.us)
