Major, Long Duration Winter Storm Friday-Saturday Generally Forecast Well
The forecast for the major winter storm at the conclusion of this past week and into the weekend was well forecast overall
Below are reported snowfall totals from across the region.
This was a very difficult forecast because the airmass was very marginal, and this it was highly elevation dependent, which is a point that was conveyed in the forecast. Note that while the forecast across northwestern half of the forecast verified very well, the southeastern edge of the snowfall, across the southern Worcester hills and the hills of north eastern Connecticut was overdone.
The reason being that the airmass was just so marginal that iy was very difficult to discern what exactly would transpire. Not only does climatology dictate that more often than not the higher terrain of this area will see appreciable snowfall, but much of the forecast did, as well. However, clearly did not end up being the case in this area, as the 3-6" forecast verified as 1-3". Another area of difficulty was the lowest portion of the Connecticut river valley in Massachusetts, in was some areas such as Greenfield were forecast to receive 3-6" of snowfall and actually received under an inch. The rest of the forecast verified well, with areas such as Wilmington, VT, on the east slopes of the Green mountain range, accumulating over 2' of snowfall, as was expected in isolated area. Several locales in the higher terrain of the northern Berkshires received upwards of one foot and a half of snowfall.
