NEAR TERM /THROUGH MONDAY/... As of 936 PM EST Saturday...Have replaced Winter Storm Warnings with Winter Weather Advisories with this update as remaining snowfall rates will generally be light away from the higher terrain. We continue to watch as closed mid- upper level low translates newd from central NY across VT. As vertically- stacked system shifts newd, will see a gradual increase in low- level westerly flow, with snowfall becoming more orographic in character after midnight and into Sunday morning. Also noting from the BTV- 4kmWRF that Froude numbers increase above 1 after 08Z. That should signal a tapering off of any remaining accumulating snow around BTV after 08Z, and will see snowfall increasingly confined to the immediate western slopes/summits and some downwind areas of central/nrn VT as we head toward daybreak and beyond on Sunday. The Winter Weather Advisories run through 4PM Sunday, and will see some continued accumulating snow across the Adirondacks and spine of the central/nrn Green Mtns through late afternoon on Sunday. We`ve seen some rain/snow mix at times this evening at PBG/RUT, but should see 1C or so of PBL cooling to result in nearly all snow thru the remainder of the event. In terms of additional snowfall amounts, expecting 1-3" in the immediate Champlain and St. Lawrence Valleys, with generally 2-5" across the Adirondacks, and 3-5" across central/nrn VT. The orographics will help from Mt. Mansfield to Jay Peak with localized totals up to 12" are expected near summit elevations. Road temperatures may fall a degree or two overnight, so untreated roads may become icy for those that need to travel.
Almost like one of the btv lurkers heard our discussion a few days ago...it’s not quite a “pf and the picnic tables” but really appreciate the details.
