[Weather] [2024.01.26 PM] Coastal Storm and Accumulating Snow Potential Sunday into Monday

[BOX Operations - NOAA Service Account]

Good afternoon,

Following is an initial one-page weather briefing and supporting graphics
regarding a coastal storm that has the potential to bring accumulating
snowfall to Southern New England Sunday into Monday.

Winter Storm Watches have been issued for Sunday into Monday for the
Berkshires, northern Worcester County and northwest Middlesex Counties.

As mentioned in a previous e-mail sent this afternoon, mainly snow is
expected for the duration in the higher elevations and the greatest
potential for highest snow accumulations are currently anticipated here. In
the lower elevations and along the coastal plain, due to borderline
temperatures and onshore winds, rain may mix in with the snow before
changing over to snow as colder air returns southward. Snow accumulations
are subject to further adjustment, particularly in the lower elevations due
to the two above factors. Given those two sources of uncertainty - we are
including the latest official snow forecast but also a reasonable
worst-case snow accumulation. This provides an idea of the kind of
accumulations we could see if colder air supporting a changeover from rain
to snow happens sooner.

We do expect impacts to travel Sunday into Monday in the higher terrain,
and mainly Sunday night and Monday as rain changes over to snow for the
lower elevations. Impacts to the Monday commutes are anticipated.

Attached graphics include a one-page briefing, our current official snow
forecast, the reasonable worst-case accumulation, and the active winter
weather headlines in effect.

Expect our next briefing to be sent by 6 AM Saturday.

Thank You!

Meteorologists: Andrew Loconto and Frank Nocera
