...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 8 PM EDT THIS EVENING 
FOR NORTHEASTERN WORCESTER COUNTY...

impassable in Gardner, MA. . Between 1 and 3 inches of rain have 
fallen. The expected rainfall rate is 0.5 to 1 inch in 1 hour. Flash 
flooding is already occurring.

HAZARD...Flash flooding caused by thunderstorms.

SOURCE...Radar.

IMPACT...Flash flooding of small creeks and streams, urban areas,
         highways, streets and underpasses as well as other poor
         drainage and low-lying areas.

Area Forecast Discussion
National Weather Service Boston/Norton MA
402 PM EDT Mon Jul 10 2023

.SYNOPSIS...
Showers and a few thunderstorms will come to an end this
evening. Mid summer weather conditions return beginning Tuesday,
with highs into the lower 90s for many of us on Wednesday.
Chances for thunderstorms, along with humid conditions, return
for Thursday and Friday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
345 pm update...

monitoring a band of showers and thunderstorms stretching from
central MA southward into eastern CT. These have formed along a
surface convergence boundary associated with a surface trough,
combined with a modest amount of surface instability. SPC
mesoanalysis indicates lesser instability to the east of that
line, likely due to the southeast flow advecting in a more
stable marine influenced airmass. Latest hi-res models suggest
that this line may go another 30-40 miles eastward before
dissipating. This would be great news, especially across
portions of northern RI (and the PVD area) which got soaked a
little earlier today, so even a little bit of additional
rainfall would cause problems. Have made adjustments to the
hourly PoPs based on the latest HRRR and RAP models, and go with
the idea that the convective line will be dissipating between
6-7pm.

With sunset, we lose the instability and that means most of the
shower activity should dissipate. Could still be a rogue shower
or two through midnight, especially near that surface trough, as
it slowly moves eastward and eventually offshore. Once that
happens, the rest of the night should be quiet. Still rather
high humidity, so lows in the 60s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
345 pm update...

High and dry for the day. Upper level trough will push offshore
early in the day, setting us up with dry west/northwest flow.
Good amount of sunshine will promote boundary layer mixing up to
5000ft or so. Some winds of 20-25kts up that high, so we could
see occasionally breezy conditions, but overall not bad. 850mb
temperatures will be around 15C, so that supports surface
temperatures about 30C. Stuck with the NBM which had highs in
the mid/upper 80s across the region. Don't think there will be
any significant sea breeze tomorrow given the westerly flow, but
if one does form, it will be pinned pretty much to the coast.

Quiet Tuesday night. Not an overly dry airmass with dewpoints in
the 60s, so overnight lows will be in the 60s.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
345 pm update...

Given the ongoing weather today, the extended forecast is pretty
much NBM, and not much different than previous shift had. A few
highlights:

Wednesday: 850mb temperatures up around 17C, so that suggests we
should be able to reach the 90F level, especially across the
lower elevations. Dewpoints will be in the lower to mid 60s, so
although a bit muggy, it won't be oppresive. Small risk of
afternoon convection, primarily across the higher terrain of
western MA.

Thursday/Friday: Looks like unsettled weather returns. Upper
trough to our west sets up, with shortwaves rippling through the
flow that if everything works out perfectly with timing, will
result in additional showers/thunderstorms especially during the
daytime. Flow turns more southwest, so we return to a humid
airmass, thus potentially another round of threat for locally
heavy rainfall. Coordination with WPC to add in a slight risk in
their most recent ERO for both Thursday and Friday -- primarily
across western sections of SNE.

Saturday/Sunday/Monday: Broad southwest flow continues at all
levels. Looks like what mid-summer is supposed to be here in SNE
with warm and humid conditions with the chance of showers and
thunderstorms. NBM seems to offer the best forecast at this
point as those nuance details (such as low level boundaries,
timing of shortwaves, exact amounts of low level instability)
are too hard to pin down this far out in time. Thus we have
pretty much a climo forecast - highs in the 80s with a 40-50%
chance of showers/t-storms each day.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Forecast Confidence Levels:

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

18z Update

Overall moderate confidence.

Currently a mix of IFR to VFR across the region. Generally IFR
across eastern sections with low stratus, fog and moderate to
heavy rain. MVFR/VFR conditions across primarily CT. With
expected development of additional showers and isolated
thunderstorms this afternoon, the lower flight category
conditions will be more common. Showers and isolated
thunderstorms should be dissipating by 00z for the most part.
Also a weak surface trough denoted by a wind shift extends from
near ORE to east of BAF to about IJD then to GON. Southeast
winds exist to the east of the trough, with westerly surface
winds to the west of the trough. This trough will be slowly
moving eastward, and should be off the coast by midnight. Last
aspect to the forecast is the FG near the coast. Expect that to
continue through the evening, but as winds turn westerly behind
the trough, that fog should dissipate.

At this time, expect VFR conditions should be in place for much
of the region by 12z Tuesday, and that should continue for the
entire day. VFR into Tuesday night as well.

BOS Terminal...Moderate confidence. IFR for the rest of the
afternoon into early evening. Uncertainty as to whether
additional showers/isolated TSRA could reach BOS late this
afternoon. Included only VCSH at this time, but there is a low
probability for a brief TSRA to reach BOS in the 21-23z
timeframe. Improving conditions during the evening, should be
VFR by the morning push.

BDL Terminal...Moderate confidence. Should remain VFR, with the
bulk of the SHRA expected to stay to the east of the airport
this afternoon into evening.

Outlook /Wednesday through Saturday/...

Wednesday through Wednesday Night: VFR.

Thursday: VFR. Breezy. Chance SHRA, isolated TSRA.

Thursday Night: Mainly VFR, with areas MVFR possible. Breezy.
Chance SHRA, isolated TSRA.

Friday: Mainly MVFR, with areas VFR possible. Breezy. SHRA
likely, isolated TSRA.

Friday Night: Mainly VFR, with local MVFR possible. Breezy.
Chance SHRA, isolated TSRA.

Saturday: VFR. Chance SHRA, isolated TSRA.

&&

.MARINE...
Forecaster Confidence Levels:

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

345 pm update

High confidence

Showers, perhaps an isolated thunderstorm, and areas of fog will
be the primary weather through this evening. However improving
conditions expected after midnight and lasting through Tuesday
night. Winds will ultimately turn westerly after midnight and
last Tuesday. Speeds will remain less than 20 kts, so wave
heights will generally be 4ft or less through the period.

Outlook /Wednesday through Saturday/...

Wednesday through Thursday: Winds less than 25 kt.

Thursday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Seas locally approaching 5 ft. Chance of
rain showers, isolated thunderstorms.

Friday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Areas of seas approaching 5 ft. Chance of rain
showers, isolated thunderstorms.

Friday Night: Low risk for Small Craft Advisory winds with
gusts up to 20 kt. Areas of seas approaching 5 ft. Chance of
rain showers, isolated thunderstorms.

Saturday: Winds less than 25 kt. Seas locally approaching 5 ft.
Chance of rain showers, isolated thunderstorms.

&&

.HYDROLOGY...
345 pm update...

Will keep the Flood Watch up at this point, however it may be
able to come down later this evening. Really just one more batch
of convection that we will monitor. Attention the next couple of
days turns to the Connecticut River. Lots and lots of rain
further north will be sending quite a surge of water our way.
River Flood warnings already raised for points from Springfield
northward. Expect it to crest into the moderate levels. Would
think we will raise warnings for the river in CT as well sooner
than later as the flood crest should be getting down there
starting Tuesday. We will await updated forecasts from the NERFC
before making those decisions.
