UPDATE 2: Tonight-Tomorrow Storm

Champlain Valley Weather Discussion:
     Finally, just hours before the onset of precipitation, models come into somewhat better agreement. The GFS now keeps precipitation further Southeast, although it still brings snow into Central Vermont. One good thing about this, is the fact the snow that the GFS does bring into central Vermont, is showing it to be much lighter, and not likely to accumulate several inches. Infact, the thermal profile of the GFS is slightly warmer then previous runs. So as of now, there will be no alerts issued, and you can expect a rain/ snow mix tonight across Southern, and Central Vermont changing to all snow, even in the deeper valley's by very early Sunday morning, then changing back to a rain snow mix, and eventually to all rain by Sunday afternoon. Total snow accumulations will range from a Dusting to 2 inches in the deeper valley's to 1-3 inches in the higher elevations and 3-6 inches at summit levels. The heaviest snow will be confined to the summit levels, across Southeastern Vermont. Impacts should be minimal therefor no alerts are needed. I will keep a close eye as the storm continues to develop but at this time, it does appear much of the region will not be seeing any accumulating snow. Nevertheless stay tuned.
