Area Forecast Discussion
National Weather Service Boston/Norton MA
418 AM EDT Fri Apr 8 2022
.SYNOPSIS...
Low pressure near New York City early this morning will bring
heavy rains and a few rumbles of thunder as it moves northeast
into Maine and New Hampshire, with improving conditions for the
afternoon. Another disturbance aloft moving northeast on
Saturday from the mid-Atlantic states will bring renewed clouds
and showers for Saturday. Drier, cooler and breezy Sunday, but
can't rule out a few brief afternoon showers. High pressure will
bring dry and mild conditions Monday. A weak frontal boundary
will set up near southern New England Tuesday through Thursday
with a few episodes of showers possible from time to time. Mild
conditions Tuesday and Wednesday then turning cooler Thursday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
415 AM Update:
Fairly active first part of Friday morning is in store for most of
SNE due to heavy rain/downpours that could contribute to possible
urban and poor drainage flooding, as well as gusty ESE winds.
Surface analysis/METARs at this hour show surface low near the NYC
area, with elevated PWAT values being transported across SNE
associated with a SE low-level jet at 925 mb nearing 70 kt! Regional
radar shows areas of moderate to heavy rains across most of SNE,
with GLM and NLDN lightning showing a couple of flashes of lightning
across southeast MA. A stronger thunderstorm producing a few CG
strikes in more unstable air is located just SE of the forks of
eastern LI and will be moving NE into our southern waters shortly,
and eventually into the south coast by 5 AM. Downpours, perhaps
accompanied by a few rumbles of thunder, should just cause rises in
rivers but can't rule out urban or poor drainage flooding into part
of the AM commute. However rain rates to this point have been really
no better than one-half inch per hour so not expecting flash
flooding. Rain will begin to shift NE into ME/NH into the mid-
morning hrs. While SE wind gusts have been in the 35-40 mph range,
the SE low-level jet of 70 kt will continue to propagate northward
along the eastern MA coast through 12z. We haven't seen this jet
result in enhanced winds and while it remains expected that wind
gusts will not rise to the level where minor damage is expected, one
area that could is near the Cape Ann/Gloucester vicinity.
But for today, the most active portion of the forecast is over the
next 6 hours or so. Surface low and its associated heavy rain shield
moves northward by mid to late this morning. Though some lower
clouds may still linger at least initially, drier SW winds and
better mixing opportunities will allow for more rapid cloud clearing
by late this morning into early this afternoon. Thus turning much
drier by the afternoon with some SW gusts to 25 mph. Still not out
of the realm of possibility that temperatures in some locations
could near 70 degrees across the coastal plain boosted by
downsloping, but thinking the slightly delayed cloud clearing than
indicated previously supports highs closer to the upper 50s to
middle 60s, coolest in the terrain and near the south coast. After a
couple days of gray, dreary conditions, the sun will finally make an
appearance to close out the workweek.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
415 AM Update:
Tonight into Saturday:
SNE will be on the eastern periphery of a broad upper-level longwave
trough aloft. Will still have subsidence associated with weak
shortwave ridging early tonight with the passage of the morning
storminess. However for the second half of the night, will start to
see more dynamic support for increased clouds and some scattered
showers toward daybreak as a shortwave trough rotates NE from the
WV/VA Panhandle region into the north-central Appalachians. An
initially weak surface low is expected to develop near the PA/MD
vicinity and move up into NE PA by Saturday morning. This low is
expected to strengthen to below 1000 mb as it moves NE on Sat into
the Hudson and Champlain River Valleys. Modest convergence on SE
winds as surface low will focus scattered to numerous showers
especially west of I-495. There may even be some thunder as mid-
level lapse rates strengthen to around 7.5 to 8 C/km along with the
added dynamic support, which could support some small hail or
graupel in stronger showers or any isolated storms that develop.
This is the more typical shallow cold core showers with limited
instability that we see with colder air aloft. Less PoP chances
across eastern MA and Cape Cod, though as the low moves NE and
brings SW winds could see gusts on the South Coast and Cape Cod near
30 mph. Overall, not the greatest start to the weekend with more
clouds than sun and periods of showers.
Lows tonight in the lower to mid 40s. Highs on Saturday in the upper
40s to mid 50s under more cloudiness across interior MA/CT, and in
the upper 50s to near 60s eastern MA and RI.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Highlights...
* Breezy and cooler Sun with a few showers possible
* Dry and mild Monday
* Continued mild Tue/Wed with a few chances for showers, then cooler
Thu
Saturday night into Sunday...
Shortwave will have moved to the north by Sat evening with mainly
dry conditions Sun night. However, the amplified upper trough and
cold pool will be swinging through on Sun leading to increasing
diurnal cloud cover and perhaps a few showers, but not a washout. It
will be cooler as 850 mb temps drop to near -4C which will keep
highs mostly in the low/mid 50s. Breezy NW winds will make it feel a
bit cooler.
Monday...
Upper ridge approaches from the west with rising heights while
surface ridging builds into New Eng. Expect lots of sunshine, less
wind and milder temps as low/mid level warming commences. Highs will
reach upper 50s to lower 60s, overall a pleasant early spring day.
Tuesday through Thursday...
Broad upper ridge sets up across east coast with an overall mild
pattern, but multiple shortwaves riding along the periphery of the
ridge will likely keep true warm sector airmass to the south. So
while temps should average above normal, not expecting unseasonable
warmth. Will also have to watch for a potential sharp cool down by
Thu if a backdoor front moves through with cooler NE flow.
GFS appears too aggressive with northern stream trough Mon night/Tue
and generally leaned toward ECMWF solution. There may be a few
periods of showers from time to time along the frontal boundary Tue
through Thu but unable to provide any timing details at this time
range.

diminishing to 2-4 ft nearshore and 4-6 ft offshore.
For Saturday, SE winds shift to SW and could gust at SCA levels
along the southern waters. Seas 4 to 6 ft.
Outlook /Saturday Night through Tuesday/...
Saturday Night through Sunday: Winds less than 25 kt. Seas up
to 5 ft.
Sunday Night: Low risk for Small Craft Advisory winds with
