The 00z Euro would change all of Massachusetts to rain. At this time, the Euro is way out in left field, so to some extent it is being discounted. But at the same time, it's track record can't be overlooked. The 06z NAM is a little warmer, but also lays down the hammer with much stronger omega than its previous runs, and much greater QPF. Regardless of some mixing with sleet, this solution would easily give Keene 12" of snow. The GFS on its 00z run shifted notably warmer, but still keeps north of Rt 2 all snow. It also has a decent round of omega and QPF has been up around an inch for Keene. Current consensus is for 700-850mb thicknesses to reach 1540m Wednesday evening, which does increase potential for sleet mixing in. This would occur Wednesday evening and night. There is a slight possibility of freezing rain entering the mix, mainly based on the ECMWF. Will have to watch this closely. The slightest bit of accretion, with then another inch or two of snow on top Wednesday night, would introduce the possibility of delays on Thursday.

As for snowfall for Keene, any mixing would occur after the heaviest precipitation moves through (10am to 5pm), so it wouldnt cut down on accumulations too much. At this point, I'll hold at 7" to 11" through Wednesday night. If the 12z Euro backs off a little with the warming, these numbers would be raised.
