Area Forecast Discussion
National Weather Service Boston/Norton MA
355 AM EDT Tue Sep 25 2018

.SYNOPSIS...
An approaching warm front will bring a soaking/heavy rain to the
region Today with some poor drainage street flooding issues
possible. The steady rain should wind down later this evening...but
scattered showers and a few thunderstorms will be possible through
the night with locally heavy downpours.  Summer-like warmth and
humidity return Wednesday with scattered showers/thunderstorms in
the afternoon and early night. High pressure brings seasonably cool
and less humid weather for Thursday through Saturday. A cold front
moves through Saturday night/Sunday morning with a chance of
showers, then dry and seasonable weather returns.

&&

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

Highlights...

* Heavy Rain Tue with poor drainage street flooding issues possible
* Low risk for a t-storm late Tue night near the south coast

Overview...

Everything continues to come together for a
widespread soaking rain event starting early this morning and
lasting into the evening. Early this morning a warm front is
approaching from the south which will turn winds (currently out
of the NE) to the southeast then south through the day. This
warm front brings in a very moist atmospheric column, with PWATs
approaching 2" (quite anomalous for this time of year) which
will feed the heavy rain fall. We'll have plenty of forcing to
take make use of this moisture as well. In addition to the warm
front overriding the residual cold air left over from our
colder start to the week, we'll have a strong, fast moving LLJ
traversing the area today. Winds at 850 mb reach 45-50 kts, and
at 925 winds top out near 35-45 kts. The southeasterly
component to this 925 jet will potentially enhance the precip
orographically as winds flow up the terrain into western MA/CT.
Some of the latest guidance has been hitting on a few bullseyes
of 3"+ including the last few runs of the EC, and this
orographic enhancement could be a factor.

Generally, though, still expecting more widespread totals of
1-2 inches with the lowest totals over the south coast, Cape,
and Islands. Some typical nuisance flooding in urban areas with
poor drainage is expected, but not seeing much potential for big
flooding issues. One factor that will help keep this from being
more of a widespread flooding event is the transient nature of
the jet. It's a relatively quick mover, and thus the strongest
forcing for heavy precip shouldn't linger long enough to cause
serious flooding issues. Temperatures will be warmer than we saw
on Monday but still fairly cool given the cloud cover and that
winds don't switch around to the south until later in the day.
We'll range from the upper 50s to 60s, warmest along the coast.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...

The widespread rain comes to an end from west to east during the
evening as do our strongest LLJ winds, leaving us without the
strongest forcing. Showers will continue, however, as the
atmosphere remains very moist (PWAT values don't really drop)
and winds remain 35-40 kts in the low levels. This will keep
scattered showers in the forecast through the night. As
mentioned by the previous forecaster, some of the hi-res
guidance shows potential for a few thunderstorms early Wednesday
morning before 8 am. The 3 km NAM is currently the only one
really showing much of anything, but it does have good
instability (CAPE values ~1000 j/kg) to accompany the lift
provided by the LLJ and the very moist atmosphere. Something to
watch as we get closer and more in range of some other hi-res
guidance.

Temperatures will be warmer overnight given southerly wind and
WAA behind the warm front. Low dip into the upper 60s along the
coast and upper 50s in western MA.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...

Highlights...

* Summer-like warmth and humidity Wednesday
* Scattered showers & T-storms possible late Wednesday
* Mainly dry and seasonable Thursday thru Monday

Wednesday and Wednesday night...

Impressive warm sector for this time of year overspreads the region
with +20C air at 925 mb streaming across the region. These temp
anomalies are about +2 standard deviations warmer than climo and
will support highs Wed of 75-80, possibly low 80s if enough breaks
of sunshine develop. It will feel summer-ish as dew pts soar into
the low 70s! Thus summer-like warmth and humidity which will also
yield SB CAPES on the order of 500-1000j/kg. This may set the stage
for an interesting setup as strong convection exits NY state during
Wed afternoon and approaching northern and western MA late in the
day, possibly into CT as well. 0-6 km shear also increases to 35-40
kt by 00z over northwest MA. Thus low risk for a few strong storms
impacting northern and western MA, possibly into northwest CT Wed
evening with strong to damaging winds the main concern. Other
concern with any convection late Wed into Wed evening will be
potential for very heavy rainfall as PWATs surge upward to 2+
inches! This line of convection will likely weaken after 00z as blyr
cools and mid level lapse rates remain poor.

Otherwise Wed is not a complete washout with many hours of dry
weather and possibly a few breaks of sunshine. Again very summer-
like with highs 75-80 and humid with dew pts in the lower 70s. It
will be breezy with low level jet lingering across southeast MA.
This will translate to SSW winds of 20-30 mph across Cape Cod and
the Islands.

FROPA second half of the night with good drying thru the column as
PWATs crash downward along with dew pts falling into the 50s late.
Thus turning drier and noticeably less humid late Wed night.

One wildcard here Wed night is that NAM suggest moisture from
tropical depression (currently 300 miles south of Cape Hatteras)
advects northward into southern New England and interacts with
baroclinic frontal boundary/trough moving across our area to yield a
Predecessor Rainfall Event (PRE), with intense rainfall rates. Still
48+ hrs out in time and NAM model only guidance source suggesting a
PRE. Nonetheless it's something we'll have to watch.

Thursday and Friday...

FROPA late Wed night followed by weak high pressure building over
the region providing dry, seasonable weather and lower humidity Thu
and Fri. However frontal boundary stalls offshore as 591 dam
southeast ridge maintains southwest flow aloft across New England,
resulting in parallel flow to the surface front. In addition
tropical wave currently off the southeast US coast gets captured my
upper trough and streams northward off the eastern seaboard. This
low may transition from a tropical wave to a baroclinic wave
(southeast of 40N/70W benchmark Thu and Fri) on the stall frontal
boundary offshore. Only potential impact here would be for Mariners
with increased wave action.

Saturday...

Trailing northern stream short wave and attending cold front move
across the region. Weak WAA ahead of this feature will result in
milder temps Sat with highs in the low 70s, right on track for this
time of year. With dew pts in the 50s and partly to mostly sunny
conditions should be very pleasant. Only wrinkle will be the risk of
a few afternoon/evening showers. Definitely not a washout, just
scattered afternoon/evening showers.

Sunday and Monday...

Dry and cooler behind the FROPA with 1030 mb high pres building into
from the Great Lakes and OH valley. Temps may run a few degs cooler
than normal with highs both days in the 60s and overnight lows in
the 40s to lower 50s in the urban areas.

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...

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

Short Term /through Tonight/...

Today...High confidence
MVFR conditions will overspread the region this morning ahead of
a widespread soaking rain all of today. CIGS will lower to low
end MVFR/IFR during the day with heaviest rains. Rain is
expected to enter central CT and MA by 09Z and spread east to
the coast by 15Z. Heavy downpours are likely in spots and gusty
ESE winds are expected along the coast. With a SE low level jet
of around 45 kts crossing the region some LLWS is possible
during the afternoon.

Tuesday night...Moderate confidence.
Low end MVFR-IFR cigs and vsbys will continue with localized
LIFR conditions in areas of patchy fog. The widespread rain
becomes more showery in nature but persists through the night
with a scattered t-storm possible. LLWS is expected as well.

Wednesday...Moderate confidence.
Conditions slowly improve to MVFR/VFR through the day, with
shower chances continued, more scattered in nature.
Thunderstorms possible during the afternoon/evening with
localized heavy downpours and gusty winds possible. MVFR/IFR
conditions expected with showers.

KBOS Terminal...Moderate to high confidence in TAF.

KBDL Terminal...Moderate to high confidence in TAF.

Outlook /Wednesday through Saturday/...Moderate Confidence.

Wednesday: Mainly MVFR, with local IFR possible. Windy with
local gusts to 30 kt. Chance SHRA, slight chance TSRA.

Wednesday Night: Mainly VFR, with local IFR possible. Breezy.
SHRA likely, chance TSRA, patchy BR.

Thursday: VFR. Breezy.

Thursday Night: Mainly VFR, with local IFR possible. Patchy BR.

Friday: Mainly VFR, with local MVFR possible.

.MARINE...
Forecaster Confidence Levels...

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

Short Term /through Tonight/...

Today...Moderate to high confidence. Strong 40-50 kt SE low
level jet will enter the region with a warm front today. This
will bring strong small craft wind gusts to all waters and gale
force winds to the offshore waters east of Cape Anne. In
coordination with GYX...we opted to upgrade the Gale Watch to a
Gale Warning for Tue evening across our northern waters where
there greatest risk appears. Strong small craft headlines
elsewhere. Widespread rain that will be heavy at times will also
reduce vsbys for mariners. Seas build back to between 6 and 10
feet across our waters.

Tonight...Moderate to high confidence. The strongest low level
winds move out of the area and thus winds should diminish but
still expect 20+ knot wind gusts to persist overnight with the
still present LLJ. Seas will remain above small craft
thresholds across most open waters through 12z. Scattered
showers and perhaps a few t-storms along with fog will also
reduce vsbys for mariners.

Outlook /Wednesday through Saturday/...Moderate Confidence.

Wednesday: Moderate risk for Small Craft Advisory winds with
gusts up to 30 kt. Areas of rough seas. Chance of rain showers,
slight chance of thunderstorms.

Wednesday Night: Winds less than 25 kt. Areas of rough seas.
Rain showers likely, chance of thunderstorms.

Thursday: Winds less than 25 kt. Areas of rough seas. Slight
chance of rain showers.

Thursday Night: Winds less than 25 kt. Areas of seas
approaching 5 ft.

Friday through Friday Night: Winds less than 25 kt. Seas
locally approaching 5 ft.

Saturday: Winds less than 25 kt. Areas of seas approaching
5 ft.
