One change from 24 hours ago is a delay in the
changeover, especially for areas further north as the warmer air
gets hung up a bit. This has allowed for slightly increased snow
totals over northern MA before the change; still thinking 4 to 6
inches is most likely with isolated amounts up to 7 inches. While
most locations will only be dealing with rain during the day on
Sunday, the exception will be the high terrain of the Worcester
Hills and Berkshires. Given a secondary low forming directly
overhead and directing colder NE flow into the region, there is some
question as to how quickly that subfreezing air gets scoured out for
northern MA in general, as models tend to be too fast.
