Area forecast discussion, Jun 15, 1:51 AM EDT, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
151 AM EDT Wed Jun 15 2022

.SYNOPSIS...
High pressure and dry weather remains in control through Wednesday.
Cooler later tonight and Wednesday behind a backdoor cold front,
especially in eastern MA, as northeast winds develop. The threat for
showers and thunderstorms increases Thursday night into Friday,
ahead of an approaching cold front. A few strong storms are possible
Friday afternoon/early evening. Dry and cooler weather returns
this weekend, likely lingering into early next week with
moderating temperatures.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
935 PM update...

Clear skies and light winds across SNE this evening. Weak
backdoor front slides south across the region overnight with a
wind shift to NE and increasing low clouds developing across
eastern MA toward daybreak. Current forecast on track.

Previous discussion...

* Dry and quiet weather with high pressure in control. May see some
  low clouds spreading into eastern areas toward daybreak.

Ridge axis amplifies as it builds over the central Great Lakes into
Ontario tonight. During this timeframe southern New England will be
under cyclonic flow as a shortwave digs from northern ME to south of
Nova Scotia by daybreak. Anticipate a backdoor front to slide into
and through much of southern New England tonight.

Will see dry and quiet weather across southern New England tonight.
Main concern in the forecast is increasing low level clouds late
tonight as the shortwave digs to the south of Nova Scotia. This will
push the cloud cover currently situated just NE of Maine toward
southern New England late as the backdoor front slides in roughly
around the 09-12Z timeframe.

Expecting fairly good radiational cooling tonight before that cloud
deck moves in late. Due to this did lower temps to the NBM25th
percentile of guidance. Not out of the question that temps need to
be lowered a bit further if the cloud cover pushing in delays a bit
later. For now given the 925 hPa temps of 10-15 degrees Celsius
think that 50s to low 60 degrees seems reasonable for low
temperatures tonight.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/...
Highlights

* Cloudy start across much of southern New England on Wednesday, but
  should scatter out as the boundary layer grows. Will be dry, but
  cooler due to onshore flow.

* Increasing mid/high clouds Wednesday night. Cannot completely rule
  out a few showers spreading into western areas toward daybreak.

Ridge axis over the central Great Lakes/Ontario builds into the
eastern Great Lakes/Quebec by late Wednesday. The ridge builds into
the western periphery of New England by early Thursday. High
pressure builds over southern New England on Wednesday and pushes
offshore to the E/SE by early Thursday.

Wednesday...

Biggest change for folks is going to be much cooler temperatures
across a good portion of southern New England on Wednesday due to
the backdoor fronts passage. Will have onshore flow across much of
southern New England, but will shift to a SE direction during the
afternoon as the high builds overhead. Expect central and eastern
areas to be cooler with 925 hPa temps of 13-15 Celsius, while
western areas will still be roughly 15-20 Celsius. The NBM75th
percentile looked pretty good with readings in the low/mid 80s
for the CT River Valley and generally low/mid 70s elsewhere.
Only potential crux is how quickly the low clouds scatter out.
Have gone with the vast majority of the guidance which scatters
things out by late AM/early afternoon, but not completely sold
on this as sometimes it is very difficult to scour this out
with onshore flow. If this occurs then temps will need to be
reduced further in future updates.

Wednesday night...

Generally dry and quiet weather with increasing mid/high clouds
late. A shortwave may ride along the top of the ridge as is
moves into E NY/western areas toward daybreak. Not completely
out of the question there is an isolated shower or two for
western areas as PWATs increase to roughly 1-1.5 inches due to
the position of the high. Flow aloft becomes southerly with 925
hPa temps around 13-16 Celsius. Overnight lows in the mid to
upper 50s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Highlights...

* Best chance for any rain is Thu night/Fri - scattered showers &
  thunderstorms, a few may be strong Friday afternoon/early evening
* Warmest day is Friday with highs 85-90, then heat breaks with mild
  days and cool nights this weekend
* Dry weather likely early next week with moderating temps

Precipitation...

Both Euro (00z) and GFS (12z) ensembles show an airmass change Thu,
with PWATs going from below normal to above normal from 12z Thu to
00z Fri. Tight moisture gradient aloft suggest an instability burst,
with warm frontal convection possible, especially late in the day
across western MA/CT where deeper moisture and instability aloft
exist. Lead short wave trough and associated PWAT anomaly move thru
Thu night. Modest synoptic scale forcing via Q-vector convergence,
elevated instability per negative SI and deep layer moisture should
be sufficient for scattered showers and storms, with locally
downpours possible. Given day 3 forecast, not quite sure how
widespread convection will be. Friday, column begins to dry out
behind departing lead short wave, however dynamic tropopause shows a
potent trailing short wave in the WNW flow aloft moving across SNE
late in the day. Some favorable parameters for strong/severe storms
which include dew pts pooling well into the 60s from eastern CT-RI-
southeast MA and temps into the 80s yielding CAPEs of 1000-1500
j/kg. Other favorable parameters include 6.5-7.0 C/KM mid level
lapse rates and 40-50 kt of deep layer shear. Although its SNE so
there are limiting factors which include, perhaps too much dry air
aloft, as GFS and NAM bufkit indicate low RH values in the 0C to -
10C layer, not good for building updrafts. In addition, 850 mb flow
is westerly, this will limit convergence and downslope winds may dry
out the blyr too much. For this reason greatest threat is from
eastern CT into RI and southeast MA. This could be a concern given
Fri looks to be a good beach day. It will come down to how much
moisture is leftover for the trailing short wave Friday. Day 4
forecast, so definitely some uncertainty here. Post frontal and dry
for the weekend. Cold air aloft and cyclonic flow may yield an
isolated low top shower Saturday, but dry air aloft should be deep
enough for dry weather to prevail, especially Sunday when core of
PWAT minimum anomaly is over the region. Ensembles suggest dry NW
flow into Monday and possibly Tue.

Temperatures...

Thursday, SNE will be on the cool side of the warm frontal boundary,
with warm sector well to the west. This combined with increasing
clouds should limit highs Thu to the 70s. Warm sector airmass begins
to advect northeast Thu night, so becoming more humid with dew pts
rising into the 60s. Above normal temps at 850 mb Fri combined with
sunshine and westerly winds (downslope winds) will support highs 85-
90! Warm at the beaches too given westerly flow. The heat and
humidity break Fri night with post frontal airmass overspreading the
region. Very pleasant this weekend, with dry weather, mild days and
cool nights. Highs in the 70s and lows in the 50s with a few upper
40s northwest MA. Remaining dry into early next week and temps
slowly moderating to 75-80.

.TIDES/COASTAL FLOODING...
The Strawberry moon will bring high astronomical tides tonight
with tides at 12 ft MLLW for BOS and 4.3 ft for ACK. We are
running roughly 0.5 ft above the obs water level, so given this
along with weak onshore flow tonight have opted to hoist a
Coastal Flood Statement for the midnight high tide. Think that
there could be some nuisance flooding across the typical most
vulnerable locations.

Will still have high astronomical tides Wednesday night and
onshore flow. Not out of the question that another Coastal Flood
Statement will be needed for eastern areas.
