The storm is progressing as forecast. Snow will be heaviest between 11 am and 4 pm today (as forecast) with snowfall rates 1-3″ per hour at times. Expect 6-12″ of accumulation by evening, with heaviest totals in southern and eastern portions. By 5 pm, the snow will lighten up and change to light sleet and/or light freezing rain and drizzle. It now looks like the entire county will see this changeover. This light icy precipitation will continue off and on until 10 or 11 pm tonight. The sleet/freezing rain will then become steady and increase in intensity. We will likely get a total of 1″ or so of icy sleet from 5 pm to midnight. Around midnight the precipitation should change to all snow. Snow will then continue, varying in intensity, for the remainder of the night, ending in the early morning. It still looks like the heaviest portion of the “frontogenesis” band will be located just to our west during this “backlash” period after midnight. In those locations snowfall rates will be 1-3″ per hour. Even though the band will be focused to our west most of the time, portions of it may rotate through parts of the county (mostly north and west portions) during early and late parts of the period. Otherwise, snowfall will be light to moderate in Berkshire County during this period. I think we may get a little more than my forecast 2-4″ during the after midnight period, perhaps 3-6″. In contrast to our daytime snowfall, the highest totals during this period will likely be in the northwestern parts of the county. By the time all of the snow and ice is totaled up expect widespread 10-16″ totals.

I will post another update by 5 pm……
