495. Thermal
profiles/soundings indicate that temps should be cold enough in this
region for mainly snow or rain quickly changing to snow. Given
marginal boundary layer temps...greater impacts/snow accumulations
will be in the higher terrain. Strong low level southwest flow will
also result in some mesoscale enhancement along the western side of
the Berks, Worcester Hills and northeast CT Hills. This can be seen
in a lot of the high resolution model guidance QPF fields. So while
the snow amounts should be elevation dependent to some
degree...expect to see the higher snow accumulations on the
western/upslope side vs the eastern side at the same elevations.
We continued the Winter Weather Advisory for western and central MA
and also include Tolland county to account for their higher
elevation. We generally expect 2-6" of snow to fall within the
Winter Weather Advisory with the greater of those amounts in the
high terrain...particularly on the western upslope side.
