From the National Weather Service:
...WINTER STORM WATCH REMAINS IN EFFECT FROM SATURDAY AFTERNOON
THROUGH SUNDAY EVENING...
* WHAT...Heavy snow, sleet, and freezing rain. Total snow
accumulations of 6 inches or more possible with the highest risk
north of the Massachusetts Turnpike. Highest potential for over
a foot of snow is north of Route 2 in Massachusetts. In
addition, ice accretion of one tenth to three tenths of an inch
are possible, mainly to the south of the Massachusetts Turnpike,
with localized amounts up to one half inch possible.
* WHERE...Northern Connecticut, northern Rhode Island and all of
Massachusetts east of the Berkshires, except for the South
Coast, Cape and islands.
* WHEN...Mainly Saturday evening through Sunday afternoon.
* ADDITIONAL DETAILS...Snow develops by early Saturday evening.
The snow will change to sleet and freezing rain south of Route 2
between midnight and 8 AM Sunday. The bulk of the freezing rain
and ice accretion is expected south of the Massachusetts
Turnpike, where some scattered power outages are possible if
higher amounts occur. Precipitation may change to a period of
all rain along and southeast of the Boston to Providence
corridor for a time. If this occurs, rapidly falling
temperatures on Sunday may result in a flash freeze. Mixed
precipitation will transition back to a period of snow before
ending sometime Sunday afternoon or early evening.
A Winter Storm Watch means there is potential for significant
snow, sleet or ice accumulations that may impact travel. Continue
to monitor the latest forecasts.
