Champlain Valley Weather Discussion:
OVERVIEW
         Low pressure near Cape Cod will continue to move Northeast, and away from the region. A cold front moving in from the west, will bring in cooler temps and more light snow for tomorrow.
PRECIPITATION
         Well for the most part, things have gone fairly well. I did have to drop western Franklin County, VT from the Winter Weather Advisory, and downgrade the Warnings to Advisories across Western Addison, and Rutland Counties, as well as Caledonia County, as snow totals are not as high as expected. I did contemplate leaving the Warnings/ Advisories in place as an area of concentrated snow may continue across the Champlain Valley and western slopes of the green mountains as winds shift to the North and Northwest, and produce convergence, and upslope snows. Also another area of snow will develop across much of the region as a cold front and associated waves of low pressure ride up along the front, including isolated snow squalls, but with looking at all the pieces, the snow would occur over a fairly long period of time, not to mention the later is a completely separate system, so I decided adjusting the Warnings/ Advisories were an appropriate idea. Conditions will be monitored closely tomorrow morning though as Snow squalls are possible around the morning commute time frame.
