| Episode Narrative | A very powerful low pressure system (980mb) moved across the Great Lakes into Ontario province Canada on December 9th. Snow overspread the region before dawn with snowfall rates in excess of an inch per hour during the morning commute along with brisk winds of 15 to 25 mph with higher gusts. The snowfall ended by early to mid afternoon. Snowfall amounts ranged from a few inches in the northern Champlain Valley and along the western slopes of the Green Mountains to 6 to 12 inches in favored up slope communities along and east of the Green Mountains. Some specific snow totals; 14 inches in Chester, 12 inches in Cavendish and Springfield, 9 inches in Bridport, 8 inches in Moretown, Rutland and Walden. This was the first widespread snow event for the 2009-10 winter season with numerous vehicle accidents throughout Vermont. More importantly, this powerful storm delivered a low-level jet stream of 80 to 100 mph around 3000 feet that flowed across the Green Mountains and downsloped into the communities along the western slopes of the Green Mountains. Surface wind gusts of 60 to 85 mph during the afternoon downed numerous tree branches and trees which knocked down power lines and caused some structural damage to several homes as well. More than 10,000 residents lost power in the peak of the storm. Some observed peak wind gusts included; 108 mph atop of Mount Mansfield (4000 feet), 87 mph in Huntington, 74 mph in Cambridge, 66 mph in Nashville, 65 mph in East Clarendon, 62 mph in Bolton and 52 mph in Rutland. |
