Overview
|
A large, prolonged winter storm produced heavy snow across the higher terrain of western Colorado and eastern Utah from November 27-November 29 and led to many lower valley locations seeing their first measurable snowfall of the season! Portions of the northern, central, and southern Colorado mountains received anywhere from 10 to 20 inches with over 2 feet of snow measured in some areas. In addition to snow, an upper level jet measuring 150 kts resided over the area and generated gusty winds, generally for areas south of I-70. These winds created blizzard-like conditions for drivers in the San Juan Mountains early Sunday morning. |
 Storm Total Snowfall November 27-29, 2016 |
Snow
Snow began late Saturday night (November 26) as the strong upper level jet moved into the Four Corners Region and brought the first round of precipitation along with it. Heavy snow first hit the San Juan Mountains before upper level flow shifted to the northwest on Sunday afternoon (November 27) where snowfall then favored the northern and central mountains. Another disturbance moved into the area on Monday (November 28) which brought another round of snow to northern and central Colorado, and then yet another wave moved in Monday night. While many breaks occurred over the three-day period, lingering moisture and favorable orographics generated the continuation of showers.
As for the valleys, the first round of snow fell on Monday afternoon. Not much accumulation occurred until a heavier band set up over the Grand Valley Monday night when half an inch to over an inch fell!
