A large low pressure system is part of a major block in the northern Hemisphere that extends from the northeast US through western Europe. A series of storms will develop around this upper level low but will miss southern New England. Downeast Maine and southern Quebec will be hit with snow over the coming days from these storms and a persistent northwest wind along with waves of moisture and lift will be sufficient for a major upslope snow event in the Green Mountains of Vermont.
Though the bulk of the snow will be across northern Vermont, central and southern areas above 2500 feet will see some flying on and off from Saturday through Tuesday. Generally 2″-4″ is expected for most elevated areas though the higher elevations and areas that tend to get more upslope snow (like Killington) could pick up 4″-8″+ of snow in this long duration event.
For areas not getting snow (like most of southern New England) an unseasonably cold and cloudy airmass will settle in. Periods of flurries are possible but they won’t amount to much. Temperatures will stay in the 30s for many areas though the valley locations and shoreline will be nearly 40. Temperatures will slowly drop through the middle of next week where 30s will be the rule everywhere for daytime highs.
Our next storm threat appears to be in the 12/13-12/14 period as the block relaxes some and the storm track energizes and changes. This could turn into a winter storm for most of us… stay tuned!
