Area Forecast Discussion
National Weather Service Boston/Norton MA
1248 PM EST Wed Jan 27 2021

.SYNOPSIS...
Light snow or a wintry mix will continue across much of Southern
New England this morning, before transitioning to a period of
ocean effect showers across parts of Eastern Massachusetts and
Rhode Island through early Thursday. The coldest air of the
season arrives late Thursday and lasts through Saturday with
another round of ocean effect snow possible near Cape Cod.
Temperatures should climb close to normal early next week, but a
low pressure system tracking south of New England should bring
snow and rain.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1230 PM Update...

Light rain/show showers are now confined to the south coast
Cape/Islands. Still expecting intermittent periods of scattered
ocean-effect snow/rain showers through this evening and
overnight mostly along the south shore/south
coast/Cape/Islands. Used HREF guidance to adjust PoPs to
chance/slight chances over these regions as HREF members are all
in a somewhat general agreement on the placement of the
scattered showers.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
* Ocean-effect showers continue through early Thursday.
* Sunshine returns on Thursday as the leading edge of Arctic air
  arrives.

Surface low exits the Carolina coast early Thursday and undergoes
rapid cyclogenesis. While it will pass too far south of the 70W/40N
benchmark to give us any synoptic precipitation, winds will build
from the NNE as the low moves off the coast into the Atlantic. Winds
are likely to gust to 30 kts. The NNE wind will be accompanied by a
region of enhanced moisture that may generate more ocean effect snow
across Cape Cod, the islands, and the South Shore of Massachusetts.
There remains a lower probability that these snow showers will
expand to the I-95 corridor or even further. But the coverage of OES
should be a lot less than on Wed.

Temperature forecast is a little more tricky but there is a model
consensus that the leading edge of the Arctic air will reach Western
MA by mid to late morning and Eastern MA/RI by the afternoon hours.
So we could see midnight highs in the 20s for our Western zones,
while further east, there could be enough time for highs to rise
into the 30s before falling. Also, sunshine returns by Thursday
afternoon albeit with falling temperatures.

&&

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

Closed upper low over Quebec sweeps south over New England Thursday
night and Friday. A portion of the upper low will linger overhead of
Maine and Eastern MA through Saturday before moving off. High
pressure moves overhead Saturday night and part of Sunday. Southern
stream shortwave and associated surface low will generate a coastal
system early Monday. This coastal system will move up the coast past
Srn New England early next week.

Height contours with the upper low Thursday night/Friday will fall
to 2-3 std deviations below normal. Expect much colder than normal
temperatures during this time and remain below normal through
Saturday night. Contours and expected temperatures climb back to
near normal early next week.

Although there are small differences in the mass fields, the models
are similar in handling the upper low and cold air outbreak late
this week and the high pressure area Saturday night and Sunday.
Confidence in this part of the forecast remains high. Later in the
forecast... the southern stream shortwave and surface low pressure
are handled similar through Saturday, but the GFS trends faster and
the ECMWF/GGEM trend slower Sunday and Monday. The ECMWF also
generates the coastal secondary off the Carolinas while the GFS
generates it off the Mid Atlantic coast. The result is a faster
start of precip from the GFS while the slower/southerly models are
about 18 hours slower. Confidence in this part of the forecast
remains low.

Details...

Thursday night through Saturday...

As noted above, cold upper low moves over the region bringing much
below normal temps. The airmass will be cold and dry with not much
moisture for clouds. So expect partly to mostly clear skies.

Strong northwest winds are expected Thursday night and Friday, with
sustained winds of 15 to 25 kt/20 to 30 mph and gusts of 25 to 35
kt/30 to 40 mph. The combination of this wind with temperature 2-3
std deviations below normal will mean wind chills of zero to 10
below at night and single numbers during the day.

The strong winds moving this cold air over ocean water temps in the
upper 30s and lower 40s will cause ocean-effect snow showers. This
will cause clouds over Cape Cod. Northwest winds will maintain
through Saturday. This fetch will favor snow showers either along or
just east of Outer Cape Cod, especially off Provincetown and Truro.

Mixing to 950-mb will tap temps of -12C to -17C at that level,
supporting max temps Friday of 15F to 25F. Airmass temps will be a
couple of degrees less cold Saturday, so max temps may reach the
upper teens to mid 20s. Dew points in the single numbers and below
zero suggest min temps to at least 0 to 15F Thursday night and
Friday night, possible with spots below zero in Wrn Mass Friday
night.

Saturday night-Sunday...

High pressure moves overhead, providing radiational cooling Saturday
night and fair weather for much of Sunday. Dew points will be 0 to
10 below west of I-95, allowing for min temps below zero in the
western interior and single numbers above zero farther east...and in
the teens along the coast. Temperatures moderate a little aloft
Sunday, so max temps should reach the mid 20s to lower 30s.

Depending on how quickly moisture from the next system arrives,
there may be increasing high clouds Sunday afternoon and night.

Monday-Tuesday...

There continues to be a roughly 18-hour difference between the fast
GFS and slower ECMWF-GGEM regarding the arrival of the next weather
system coming up the coast. It is notable that with this 00Z
run the GFS is trending later with the arrival of precipitation
than earlier runs. This and the digging trough/higher amplitude
aloft suggest a trend toward the slower solutions. Will hold
off the arrival of precip until Monday morning, which is a
compromise between the two solutions. Used two blended grid
sources that will better add the effects of the slower
solutions. P-types look to be snow inland with some rain along
the coast.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Generally MVFR conditions will prevail across southern New
England through the TAF period with VCSH at the coastal
terminals. Shorts period of IFR may be possible as well as some
observations are indicating SCT cloud cover below 1000 ft. Look
for interior terminals to improve to VFR shortly after midnight.

KBDL TAF...Moderate confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday Night: VFR. Windy with gusts up to 30 kt.

Friday through Friday Night: VFR. Windy with gusts up to 35 kt.

Saturday: VFR. Breezy.

Saturday Night through Sunday: VFR.

&&

.MARINE...
* Gale Watches issued for all waters.

Persistent northeasterly flow through Thursday will allow
periods of rain/snow showers to continue intermittently near
the coast.

Another system forms along the Carolina coast Thursday and
moves out to sea south of the waters. This system will create
gusty north- northwest winds that will draw much colder air
across the waters. This may bring gales to the waters on Friday
as well as moderate to heavy freezing spray.

Outlook /Thursday Night through Sunday/...

Thursday Night: Strong winds with gusts up to 35 kt. Areas of
rough seas. Chance of freezing spray, slight chance of snow
showers. Areas of visibility 1 to 3 nm.

Friday: Moderate risk for gale force winds with gusts up to
35 kt. Rough seas up to 14 ft. Chance of freezing spray, chance
of snow showers. Areas of visibility 1 to 3 nm.

Friday Night: Low risk for gale force winds with gusts up to
35 kt. Areas of rough seas. Chance of freezing spray, slight
chance of snow showers. Areas of visibility 1 to 3 nm.

Saturday: Low risk for Small Craft Advisory winds with gusts up
to 30 kt. Local rough seas. Chance of freezing spray. Local
visibility 1 to 3 nm.

Saturday Night: Winds less than 25 kt. Areas of seas
approaching 5 ft.

Sunday: Winds less than 25 kt. Seas locally approaching 5 ft.
