Snowfall amounts have been
increased a bit since the overnight forecast package, especially for
the more southern and eastern areas where snow on the back end of
the system is looking more robust. Though temperatures will be
dropping into the 33-34F range in eastern MA initially, guidance
indicates the chance for some more moderate to heavy snowfall
potential with rates of 0.5-0.75"/hour possible which would help to
dynamically cool the column and allow for accumulation. Generally
thinking 5 to 9 inches in the northern Berkshires and northern
Worcester Hills with 2-4 inches in northern CT through northern RI
and northeast MA, and a few inches for southeast MA. However, we
can`t rule out some isolated higher amounts; the HREFv3 indicates
decent potential for banded snowfall which if it sets up could cause
a localized bullseye. Snow tapers off from west to east from 5-9 pm.
