Area Forecast Discussion
National Weather Service Boston/Norton MA
1246 AM EST Wed Dec 20 2023

.SYNOPSIS...

A prolonged period of dry weather sets up from Wednesday through
the holiday weekend. A brief period of colder than normal
temperatures will prevail from Thursday into Friday night before
temperatures moderate through early next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...

955 PM Update...

* Dry/seasonably chilly overnight with lows mainly in the 20s

Most of the strato-cu has dissipated as of late evening.
Otherwise...high pressure to the west and a distant offshore
low pressure system will generate a dry/north to northwest flow
of seasonably chilly air. Low temperatures will mainly bottom
out in the 20s...but some upper teens are possible in the
normally coldest outlying locations of western MA.

The outer Cape & Nantucket will see clouds increase after
midnight, as cold NNW flow streaming over still relatively warm
SSTs (mid to upper 40s) generates lots of ocean effect strato-
cu. Given airmass is only seasonably cold, low level lapse rates
likely not sufficient for much more than a few ocean effect
flurries or sprinkles. Hence, a mostly dry night for all areas.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/...

250 PM update...

Key Points...

* Sunny Wed with highs in the lower-middle 40s

Wednesday...

Open trough moves across New England and pinches off as a closed low
ESE of the 40N/70W benchmark over Georges Bank. Plenty of subsidence
of the northwest side of this feature, which yields dry weather and
abundant sunshine Wed for SNE. The exception will be leftover ocean
effect strato-cu across the Cape and Nantucket in the morning, which
should give way to partial afternoon sunshine.

Seasonably cold with highs in the upper 30s (high terrain) and lower
40s. Very pleasant for late December given abundant sunshine and
light NNW winds, except 15-25 mph across Cape Cod and the Islands.

Wednesday night...

Dry weather continues as closed low southeast of Nantucket moves
farther out to sea, but system does intensify as it pulls away from
SNE. This yields increasing northerly gradient overnight across the
region.  Meanwhile, northern stream short wave moves across
southeast Quebec and into New Brunswick. This increases low level
CAA into SNE, with lows in the 20s but colder wind chills from north
winds 10-15 mph, except up to 30 mph across the Cape and Islands.
Mostly clear conditions expected, except Cape Cod and Islands as
ocean effect strato-cu develops in cold northerly flow.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

Key Points...

* Quiet with mainly dry weather through early next week

* Below normal temperatures Thu into Fri night, then moderating next
  weekend into early next week. Gusty N winds near the coast Thu

Overall, a very quiet period heading through the holiday weekend
into early next week. Strong high pres to the north Thu with low
pres offshore will bring gusty N winds along the coast with perhaps
some ocean effect clouds/flurries over the outer Cape. Otherwise,
diminishing wind Thu night into Fri as the high pres builds S across
SNE. PWATs are quite low Thu/Fri with a modest surge in moisture on
Sat ahead of a weak shortwave which approaches from the west. Can't
rule out a brief shower sometime Sat as milder air moves in but more
likely just some extra cloud cover on Sat. Then another high pres
builds in with rather low PWATs for Sun/Mon. Looks like dry weather
will hang on into Tue as the high pres is slow to depart.

A brief period of colder than normal temps expected Thu into Fri
night. Daytime highs mostly in the 30s with lows in the teens as
winds diminish leading to good radiational cooling. Then temps will
moderate into early next week with highs well into the 40s by
Sun/Mon.

kt. Large ESE swells persist. Dry weather and good vsby.
