Area Forecast Discussion
National Weather Service Boston/Norton MA
1005 PM EDT Wed Jul 7 2021

.SYNOPSIS...
A front will stall near southern New England Thursday, resulting
in cooler weather along with more showers and thunderstorms.
Heavy rainfall Thursday night through Friday night will introduce
the potential for localized flooding across southern New England
as Elsa, or its remnants, moves over southern New England.
Unsettled weather through the weekend and early next week with a
chance for showers/isolated thunderstorms each afternoon.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...

10 AM update...

Short wave trough moving across southeast Quebec is dragging its
surface boundary/cool front into northern MA as of 10 pm. This
boundary will continue sagging south into CT/RI and southeast MA
overnight. Convection along and near this front will dissipate
overnight, as best shear tracks across northern New England and
higher instability remains south-southwest of New England. Thus
diminishing trend in showers/T-storms overnight, with storms no
longer a severe threat. Only issue will be some heavy downpours
yielding areas of minor street/highway flooding.

Given the front will not drive south of New England, despite a
wind shift to the N-NE later tonight, not expecting a big
airmass change. Therefore, remaining warm and humid overnight
with lows in the 60s along with dew pts in the same range.
However northern-northeast MA may see dew pts dip into the upper
50s toward daybreak, providing some relief to that region.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
Nearly stationary front remains draped across the region, with
cooler air across northern MA, especially northeast MA with NE
winds off the Gulf of ME. As this boundary lifts north, warm
sector airmass surges back across the region from south to
north. Lots of timing issues remain, with a big bust potential
on temperatures near this front. at this time, thinking this
front will not make it much farther north than the Mass Pike, so
have the highest temperatures south of there. A subtle shift of
only 20-50 miles could boost temperatures 5-10 degrees higher in
Boston and Worcester.

Thinking yet another round of showers for our region, with a
lower risk for thunderstorms. Probably will not be able to
generate much instability to fuel them.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
Thursday Night Through Friday Night

* Heavy rain Thursday night ahead of Elsa
* Elsa moves over southern New England Friday with heavy rain
  and gusty winds
* Unsettled weather through the weekend and early next week.

A warm front will lift north through southern New England
Thursday night into Friday morning ahead of Elsa. With rich
moisture in place to the tune of nearly 2 inches of PWATs there
will be the potential for heavy rainfall and flash flooding.
Additionally with 30 knots of bulk-shear and close to 1000 J/Kg
of MLCAPE, there will be a thunderstorm threat as well. WPC
currently has the areas west of I- 495 in as slight risk for
excessive rainfall for the Thursday morning through Friday
morning time frame. Anywhere from 1-2 inches of rain are
expected during that period with locally higher amounts
possible.

Elsa continues to be the highlight of the extended forecast.
Latest guidance takes Elsa over southern New England sometime
early Friday morning. Confidence is becoming high that we will
see at least some impacts from this system as both deterministic
and ensemble guidance are in strong agreement for a closed low
passing over southern New England sometime Friday morning. There
remains some uncertainty however in whether or not the forecast
region will see tropical storm force winds with this system.
NHC currently has the southeastern zones in a 10-20 percent
probability of tropical storm force winds as the system moves
through the area. While ensemble guidance from the ECMWF and GFS
are in agreement with the general track of Elsa, there is
significant disagreement with respect to the potential for
tropical storm force winds (>34 knots). The EC currently has a
30-50 percent probability for winds >34 knots over the South
Coast, Cape, and Islands. The GFS on the other hand has less
than a 10 percent chance. Thus, the 10-20 percent chance NHC
currently has is more than reasonable.

Confidence is higher that we'll see substantial precipitation
from Elsa. Ensemble means from the GEFS/ECMWF are suggesting
widespread areas of 2-3 inches of rainfall in the period from
Thursday night through Friday night with locally higher amounts
likely. This will again introduce the possibility of flash
flooding, especially in urban areas and areas with poor
drainage. WPC currently has the southeastern zones minus the
Cape and Islands in a slight risk for excessive rainfall for the
Friday morning trough Saturday morning period with areas
elsewhere at a marginal risk. This may be adjusted in future
outlooks. What is important to note is that all of southern New
England will have the potential to see some localized flooding
between Thursday night and Friday night as tropical downpours
are a certainty.

Elsa is expected to be clear of the region sometime late
Friday.

Saturday through Wednesday

Seasonable temperatures and unsettled conditions forecast
through the weekend and early next week. A persistent Bermuda
high continues to pump warm moist air into southern New England
from the southwest. Meanwhile an upper-level trough at 500 hPa
will be digging into the Midwest early next week. Latest model
guidance suggests that embedded short-waves downstream the
trough axis will produce the forcing necessary for some isolated
to scattered showers each afternoon through Wednesday. There
will also be the potential for some diurnal thunderstorm
activity as there should at lest be some instability to work
with during the afternoon hours. Daily low/high temperatures in
the 60s/ upper 70s-lower 80s respectively each day.

.AVIATION /02Z THURSDAY THROUGH MONDAY/...
Forecaster Confidence Levels.

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

02z update...

Thunderstorms will continue to weaken late this evening and
overnight. Frontal boundary over northern MA at 02z will
continue to sag south overnight into CT/RI and southeast MA,
with a wind shift to the N-NE. VFR all terminals at the moment,
but IFR/LIFR conditions at KACK may spread inland into southeast
MA/RI and the CT River Valley overnight, although confidence is
below average. Previous discussion below.

===================================================================

Thursday...Moderate confidence.

IFR/MVFR in the morning in patchy fog and showers, eventually
improves to VFR during the afternoon. Showers in the morning,
trending drier in the afternoon but showers and storms could
invade the region late in the day.

Thursday Night...Moderate Confidence

Ceilings come down to MVFR and IFR late tomorrow as heavy
rainfall associated with Tropical Storm Elsa begins to
overspread southern New England. Heavy rainfall may result in
IFR visibilities of 2SM.

KBOS TAF...High confidence in TAF. Sea breeze looks to hold just
offshore of the terminal until perhaps right before the evening
push. Chance of thunderstorms from 22Z-01Z. Strongest storms
likely in western and central MA.
