Area Forecast Discussion
National Weather Service Boston/Norton MA
203 AM EDT Sat Oct 21 2023
.SYNOPSIS...
Scattered showers across interior southern New England become
more numerous again overnight. Steady rain overspreads the
entirety of southern New England by Saturday as coastal low
rapidly intensifies off the coast. Cold front will bring an end
to the rain Saturday evening but gusty winds will develop late
Saturday into Saturday night. Gusty winds are expected Sunday
with a few showers possible...but dry weather will dominate.
Seasonable temperatures Monday will moderate to above normal
levels by the middle of the week with mainly dry weather
prevailing through Friday.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
2 AM Update...
Showers continue moving northward across SNE, and can't rule
out an isolated t-storm in western New Eng where marginal
instability present. Area of locally heavier showers over the
ocean may impact the Cape/Islands next 1-2 hours and showers
will fill in across eastern MA early this morning. Still
expecting the focus for widespread showers to shift across
western New Eng toward daybreak as negative tilt upper trough
approaches from the west increasing large scale ascent.
Temperatures will remain steady in the upper 50s.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Coastal low pressure comes into play on Saturday, interacting with
second low pressure to our north and the approaching cold front from
the west. The coastal low, aided by the continued negatively tilting
trend of the trough, will, for lack of better wording, explode just
southeast of mainland southern New England between 12-18Z Saturday.
As this low intensifies, mid level frontogenesis along the "Cold
Conveyor Belt" that will begin to wrap around the back side of the
low will greatly enhance precipitation efficiency with widespread
moderate to at times heavy rain likely, especially across the
downslopes of the Berkshires and Worcester Hills. Both global and
high resolution guidance suggests that the bulk of our QPF from this
system will fall between 12-20Z tomorrow. While global ensembles,
such as the GFS and ECWMF, are not keen on QPF exceeding more than
2" of rain, with ensemble probabilities of less than 10-20%, hi-
resolution guidance pinpoints the potential for widespread 2"+ QPF
totals across far western MA and northern CT. Overall, a general
0.5"-2" of QPF can be expected for Saturday. With that said, HREF
LPMM QPF hints at a few 3"+ pixels across the Berkshires,
insinuating there is a chance for locally higher amounts.
Cold front approaches from the west and eyes southern New England
Saturday evening, which will result in showers dissipating quickly
from SW to NE between 18-00Z. Some showers will linger overnight,
especially north of the MA Turnpike, but wont amount to much more
than a few hundredths of QPF. Fortunately, flooding does not
appear a major concern with this system, as a recent period of
dry weather has brought 1 hour FFG up to ~2-3" across the
region. Isolated poor drainage flooding can't be ruled out
however, especially across the high terrain, in areas where leaf
debris has begun to accumulate in storm drains.
Winds will prove to be the more heightened concern with this system
Saturday evening into Sunday as coastal low pressure rapidly
intensifies south of Cape Cod before moving northward into the Gulf
of Maine. Both the GFS and NAM hint at the development of a 65kt
925mb LLJ, concentrated along the southern edge of the low. Given
the position of the LLJ relative to the low, we first expect winds
to increase across the Cape and Islands late Saturday afternoon and
Saturday Evening before strengthening from south to north
across the CWA. Gusts will range from 25-35kt for much of the
interior, with potential to gust in excess of 40kt across the
Cape and Islands. There is high confidence 40kt winds will be
experienced across Nantucket, with NBM 4.1 probs of wind gusts
exceeding 41kt around 70%, thus, we have issued Wind Advisory
from 21Z Saturday through 18Z Sunday. A further expansion of
this advisory is possible in later forecast updates to include
the Cape, Martha's Vineyard, the Worcester Hills, and perhaps
even the downslopes of the Berkshires, depending on trends as
all locations are currently forecast to gust to just below wind
advisory criteria. Main concerns will be some scattered power
outages due to downed branches given the trees are still mostly
fully leafed.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Highlights...
* Gusty west winds Sun with dry weather dominating but a few showers
expected especially later Sun/Sun night across northern/eastern MA
* Seasonable high temps Mon in the upper 50s to the lower 60s with
areas of frost possible late Mon night/early Tue AM
* Mainly Dry with above normal temps Tue through Fri especially Wed
& Thu when the potential for 70+ high temps exists in some locales
Details...
Sunday and Sunday night...
Strong low pressure will have lifted into the Canadian Maritimes by
early Sunday morning. Therefore...the steady rain will have already
departed. In fact...much of Sunday will probably be dry but there
will be another piece of strong shortwave energy working in from the
west. This will result in an abundance of strato-CU and a few
showers...especially later Sun into Sun night across northern and
eastern MA. Certainly not expecting a washout like much of Saturday.
Sunday should also feature gusty west winds behind the departing
storm system. However...the 850/925 mb wind fields weaken after
daybreak Sunday. So thinking mainly west winds on the order of 25 to
35 mph with perhaps a few gusts near 40 mph in the high terrain.
High temps will be in the 50s to near 60...but will feel a bit
cooler with those gusty winds.
Monday and Monday night...
The bulk of the upper level shortwave energy will have departed by
Monday. Perhaps a few lingering light showers early Monday across
the Cape/Nantucket...but expect generally dry weather with more
sunshine than Sunday too. Highs on Monday mainly in the upper 50s to
the lower 60s with a bit of a northwest breeze. A ridge of high
pressure builds over the region Monday night which should allow for
many locales to bottom out in the 30s resulting in the potential for
frost.
Tuesday through Friday...
An upper level ridge of high pressure builds across the Gulf of
Mexico during the upcoming work week. This helps to pump up height
fields across the eastern states. The GEFS/EPS/CMC Ensembles all
agree on higher than normal height into New England over this time.
Therefore...expect above normal temps with highs mainly in the 60s
and perhaps 70+ in spots with the best chance Wed and Thu. It also
looks to mainly dry weather with any real synoptic scale forcing to
our north and west.
