Area Forecast Discussion
National Weather Service Boston/Norton MA
333 AM EDT Wed Apr 25 2018

.SYNOPSIS...

Low pressure approaching from the southwest will bring a soaking
rain today and into this evening.  Locally heavy downpours may
result in some brief nuisance poor drainage street flooding with an
isolated thunderstorm or two possible.  Seasonable temperatures
follow for the remainder of the week with mainly dry weather other
than a brief period of rain showers likely Friday.  A cool down will
occur Saturday night and Sunday, but this will be short lived as
unseasonably warm temperatures appear to be in store for the region
by the middle of next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
955 PM Update...

Temperatures have been very slowly decreasing hours while
dewpoints have slowly increased as seen on surface observation
trends since 22Z. Still noting rather wide T/Td trends, though
they are lower across the immediate S coast and especially on
the islands from the 01Z observations, down to 3 degrees at
KACK.

Weak ridging extending westward from high pressure SE of Nova
Scotia keeping precip at bay this evening with the continued dry
airmass, though noting reports of -RA at KJFK at 01Z.

With mainly cloudy skies across the region, along with winds
becoming generally E-SE, should see temps continue to fall
slowly overnight.

Have updated near term forecast to bring conditions current, but
not a whole lot of changes from the previous update.

Previous Discussion...

Model trends have slowed the timing just slightly for the onset
of the warm advection rainfall. This is due to such a dry
airmass in the mid-levels (700-800mb). BUFKIT soundings moisten
the profile out west by 06z and over the east around 10z. Thus
went ahead and slowed the timing. Aside, expect clouds to
thicken and lower during the overnight hours before the
precipitation begins to fall. Anticipate showers to start due
to isentropic lift and in the WAA pattern. Heavier precip will
fall by 09-12z from west to east towards the morning hours.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/...
Wednesday into Wednesday night...

*** Heavy rainfall and isolated thunder for Wednesday ***

Southern stream surface low will approach the region on Wednesday as
northern stream trough swings into the area from southern
Canada. This surface low will move across the region, allowing
for the southern half of SNE to become warm sectored. This upper
level trough will continue to dig and go negatively tiled
pushing the surface low up into the Gulf of Maine by Thursday
morning.

Rainfall...

Steady rainfall will stream into the region by Wednesday morning as
PWAT values increase to 1.3 inches, 1-2 STD above normal. Associated
with this system, strong LLJ nearing 3 STD above normal will allow
for strong moisture transport into the region. Right now appears
that widespread 1-2 inches of rainfall will occur through Wednesday
night. Think the highest amounts will occur across the Worcester
hills and the east slope of the Berks where upslope flow will help
create a bit more lift. Cannot rule out the potential for 2+
inches in that region, which is indicated by the ARW. Still with
this much rainfall, appears the the main stem rivers will
remain in their banks per NERFC's forecast and MMEFS. Still, we
will have to watch some of the flashy streams. Right now believe
that urban and poor drainage flooding will be the main threat.
Precip will come to an end by late Wednesday into the overnight
hours as main jet lifts farther north. Models also show some
drying into the mid to upper levels which could result in
showery weather towards Thursday morning.

Wind...

As mentioned before, strong LLJ increases during the day on
Wednesday reaching close to 3 STD above normal. In fact, 925mb winds
increase between 50-60 kts. Believe that most of this wind will
remain elevated as soundings show a strong inversion across the
area. However, could see some mixing near the southeast coastal
plain where the potential for thunder could bring down a few strong
winds gusts. Also appears to be a narrow window where lapse rates
may be steep enough. Believe that we could see somewhere near 25-35
MPH across the southeast coastal plain. Will hold off in any adv for
this time as confidence is not that high.

Thunder...

A low risk for thunder during the day on Wednesday as we warm
sector just a bit by the afternoon hours. Models indicate that
showalters drop below 0 and there is some elevated CAPE nearing
a few hundred joules. Like the timing of the SPC HREF MU CAPE
so tried to incorporate that into the forecast. Biggest risk
would be heavy rainfall and some gusty winds within any
thunderstorm.

Fog...

As the system begins to wind down late Wednesday night into Thursday
morning, we may have to watch for the potential for fog. High
dewpoint airmass will still be over the region Wednesday night and
with some drying in the mid-levels, low levels appear to remain
saturated. Winds also appears to be light. So aside from some
showers moving across the region, may have to watch for patchy dense
fog, especially across the south coast.

&&

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

Highlights...

* A 1-3 hour period of rain showers likely Fri

* Milder Sat with just a few brief afternoon/evening showers possible

* Dry and noticeably cooler Sun with frost potential late Sun night

* Dry weather Mon/Tue/Wed with a significant warming trend and the
  potential for 80+ in some locations by the middle of next week

Details...

Thursday night...

A ridge of high pressure will result in a dry/tranquil night.  Low
temperatures should bottom out in the upper 30s to the middle 40s in
most locales.

Friday...

Shortwave trough remains to our west and it will eject a piece of
energy into our region on southwest flow aloft.  Appears there will
be enough forcing for a 1 to 3 hour period of rain showers sometime
Friday into early Friday evening.  Certainly not looking at a lot of
rain...but appears the likelihood that most locations do see a
brief period of rain showers.  Clouds and the likelihood of a brief
period of wet weather should hold high temps mainly in the
lower 60s.

Saturday and Saturday night...

A milder day is on tap for Saturday ahead of an approaching cold
front.  Southwest flow and partial sunshine should allow high
temperatures to recover well into the 60s to possible around 70 in a
few locales.  While dry weather should dominate...an approaching
cold front may trigger a few brief showers during the
afternoon/evening.  Greatest risk will be across western MA...where
forcing/moisture will be a bit deeper.  Turns cooler Sat night
behind the cold front.  Low temps by daybreak Sun should be down
into the upper 30s and lower 40s.

Sunday and Sunday night...

Deep trough sets up across the Northeast with anomalously low height
fields.  It will be noticeably cooler...but highs should still top
out well into the 50s with good mixing in northwest flow along with
the benefit of the increasing spring sun angle.  The dry airmass in
place will allow for chilly temps late Sun night into early Mon am.
Lows should bottom out in the upper 20s to the middle 30s in many
locations.  Frost headlines may eventually need to be considered
where the growing season has officially started.

Monday through Wednesday...

The northeast trough quickly moves east of the region Monday and
will be replaced by strong upper level ridging by the middle of next
week.  The result should be dry weather with a significant warmup.
High temps should recover into the lower to middle 60s
Mon...probably well into the 70s by Tue...and the potential for some
80 plus degree readings on Wed.  A weak pressure gradient will
likely allow for sea breezes and cooler conditions along the coast
at times.  Nonetheless...at least a taste of summer afternoon warmth
appears to be in the cards for much of the region.
