Lightning Strikes in Massachusetts, September 22, 2022

Area Forecast Discussion
National Weather Service Boston/Norton MA
712 AM EDT Thu Sep 22 2022

.SYNOPSIS...
Cold front moves through the region this morning and afternoon with
potentially strong thunderstorms. Cold and blustery conditions
settle in behind the front for Friday and Friday night. Milder and
more seasonable weather will return this weekend into early
next week. A few showers will be possible from time to time in
the Sunday night through Wednesday time frame, but a washout is
not expected.

&&

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

710 AM Update...

* Scattered strong to severe thunderstorms possible today
* Locally damaging wind gusts & heavy rain/street flooding

Showers and  thunderstorms were impacting mainly extreme west
and north central MA early this morning. This activity was
mainly elevated, but enough MUCape of 1000+ J/KG was present. So
hail is possible in the strongest cores.

The main severe weather threat will roughly be from 9 am to 1
pm across western MA/CT and late morning through about 4 pm
across eastern MA/RI. This is when the associated cold front and
its associated strong forcing arrives. Quite the impressive
dynamics will be present with effective shear of 45-55 knots and
500-1000 J/KG of Cape. These type of events are challenging to
forecast because a small change in Cape can make the difference
between numerous severe thunderstorms vs. not much of anything.
Some of the latest machine learning probabilities have
increased the potential for severe weather over the past 24
hours. In fact...the latest SPC SCRAM is very aggressive in
showing high probs of a line of showers and thunderstorms with
the potential for strong to damaging wind gusts. Given the
strong dynamics and fully leafed trees there is concern for
pockets of wind damage and power outages. While this potential
exists across the entire region; greatest risk will be across
eastern MA & RI where instability and effective shear will be
maximized.

The other concerns will be frequent cloud to ground lightning,
heavy rain and brief street flooding. Enhanced wording has been
included in the forecast. Temps in the upper 60s and 70s will
fall sharply into the upper 50s and lower 60s immediately behind
the cold front.

Previous Discussion Below:

Robust mid-level short-wave trough digs and deepens into the
northeast this morning and afternoon. This will force a surface cold
front through the region that will produce widespread heavy rainfall
and perhaps a fine line of convection capable of producing damaging
wind gusts. While there is strong deep layer wind shear on the order
of 50 knots in the 0-6 km layer and very strong synoptic forcing for
ascent, the limiting factor with respect to severe thunderstorm
potential this afternoon will be instability. Most of the region
will only have around 100 J/kg of CAPE to work with. However,
greater instability develops over southeast MA and RI early this
afternoon just prior to the arrival of what should be a fine line of
convection. Enhanced instability and fairly steep low-level lapse
rates over this region will put this area at the greatest risk for a
strong to severe storm. The most likely hazard will be damaging wind
gusts capable of taking down large tree limbs which are still fully
leafed. Also can't rule out a strong to severe storm developing in
the warm sector this morning ahead of the cold front. Steeper mid-
level lapse rates ahead of the front may allow a few of the
scattered warm sector storms to produce some small hail.

As far as timing goes, we're already beginning to see some warm
sector storms on radar just over the MA/NY border. A few of these
scattered storms will be possible through this morning. By around
mid-morning we should start to the see a line of showers and storms
moving into western MA and CT. Currently expecting this to be a
relatively fast moving line that will reach the Worcester area
around 10-11 am and eventually the eastern areas by noon. The front
is expected to exit off the southeast coast by mid to late
afternoon. Wind shift to northwest behind the front.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...

Tonight

Skies clear behind the exiting cold front as deep northwest flow
advects a continental polar air mass over the northeast. Strong cold
air advection causes temperatures at 925 to plummet to temperatures
just slightly above freezing. Currently expecting a cold and
blustery night tonight as moderate northwest winds will be blowing
from 10 to 20 knots. However, the strong winds will support
mechanical mixing that will limit radiational cooling. Generally
expecting widespread low temperatures in the low to mid 40s at the
surface. Areas near the coast stay a bit more mild in the upper 40s
to low 50s.

Tomorrow

More of a late fall feel tomorrow as strong cold air advection aloft
continues to support below normal temperatures in southern New
England. Steep low-level lapse rates will support efficient mixing
and a windy afternoon. Northwest winds from 15 to 20 knots may gust
as high as 25 to 30 knots across much of the region. A dry day for
most, but northwest flow over the warm Cape Cod Bay waters may
support a few ocean effect showers for those over the outer Cape. At
the very least expect ocean effect clouds to hide the sunshine from
this area. Elsewhere, the dry column will support mostly sunny
skies.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

Highlights...

* Blustery & Quite Chilly Fri night
* Mainly Dry with moderating temps this weekend especially by Sun
* A few showers at times Sun night through Wed, but not a washout

Details...

Friday night...

A ridge of high pressure will combined with Hurricane Fiona passing
well to our east and into the Canadian Maritimes Friday night. This
will continue to result in blustery conditions with gusty NW winds
and unseasonably chilly temperatures. Appears that there will be
enough wind aloft to keep the region from decoupling. This should
result in overnight low temps mainly in the upper 30s to the lower
40s. If a few of the typically most prone low-lying locations are
able to briefly decouple; overnight lows would drop in the lower to
middle 30s with frost. If this does happen it would be very
localized; so no frost headlines anticipated at this time.

This Weekend...

Deep upper trough will lift into the Canadian Maritimes this weekend
allowing for rising height fields. This should allow for high temps
to recover well into the 60s in many locations Saturday. It still
will be breezy on Saturday, but not as strong as on Friday.
Temperatures will moderate further by Sunday as the next shortwave
drops into the eastern Great Lakes. This should allow high temps to
reach back into the 70 to 75 degree range in many locations.

Generally expecting dry weather for most of the weekend. Approaching
shortwave should result in some mid/high cloudiness gradually
increasing as Sunday wears along. May even have a few showers
entering our western zones toward evening. However, main threat for
some showers will not be until Sunday night when warm
advection/forcing increase ahead of an approaching shortwave.

Monday through Wednesday...

Forecast confidence diminishes in the Mon through Wed time frame.
Deep upper trough will drop into the eastern Great Lakes Mon/Tue
allowing for some shortwave energy to rotate into our region at
times. However, timing and magnitude of the energy are uncertain.
All we can say is there will be the risk for a few showers at times
Mon and Tue, but not expecting a washout by any means. Seasonable
temps expected with highs mainly in the upper 60s to the middle 70s.
Appears the trough axis may shift to our east by Wed, resulting in
cooler temps with highs mainly in the 60s.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...

Forecaster Confidence Levels:

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

High confidence.

12Z TAF Update...

Today...Moderate Confidence. Active day with numerous showers
and thunderstorms with frequent lightning already working into
western and north central MA. Main activity will be through
16z-17z across the interior and through about 19-20z across
eastern MA/RI. Brief IFR-LIFR conditions are expected in the
thunderstorms with torrential rainfall and locally strong wind
gusts. Outside the thunderstorms, winds continue to increase out
of the southwest gusting to 20-30 kt ahead of cold front, then
shifting to NW behind the front during the afternoon. Again
Stronger wind gusts possible in storms, especially in RI and
southeastern MA.

Tonight...High Confidence. Mainly VFR but with brief marginal
MVFR cigs possible across the interior. NW winds 10-15 kts
gusting 20-25 knots with a few gusts up to 30 knots possible.

Friday...VFR outside some marginal ocean effect MVFR cigs at
times on the Cape and Nantucket. Moderate northwest winds 15 to
20 knots with gusts of 25 to 30 knots with a few gusts up to 35
knots possible.
