Area Forecast Discussion
National Weather Service Taunton MA
1027 PM EDT Mon Mar 13 2017
.SYNOPSIS...
A major winter storm will impact the region Tuesday with heavy snow,
strong winds and coastal flooding. The snow will change over to a
period of rain along coastal areas Tuesday afternoon into Tuesday
evening, before changing back to snow before tapering off. Blizzard
conditions are likely across northeast Massachusetts and along west
of the I-495 corridor. Blustery Thursday, then fair and cold Friday
as high pressure builds in. Another round of unsettled weather is
possible this weekend, but the timing is not yet certain.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
1030 pm update...
Surface pressure falls emerging off the SC/FL coastline with both
convective activity and moisture transport increasing within the
amplifying baroclinic zone out ahead of a stout potential vorticity
anomaly with an impressive tropopause fold below H5 across MS/AL.
The cyclonic tilt of the mid to upper level wave pattern, should
see ingredients wrap together into regions of strong deep layer
ascent out ahead of the surface-H85 low. Anomalous precipitable
waters above the 90th percentile ingesting into the deepening
low with pressure falls approaching 5 mb / hour towards morning,
will see the continued trend of cooling cloud tops as has been
observed the last few hours already. Influx of deep moisture
from sub-tropical regions aided by highly anomalous low-level
easterly flow.
Warm conveyor belt motions, likely to see some light snow spread
across S/W portions of New England towards morning as moisture
undergoes ascent along isentropic surfaces. Expect emergence of
snow out of a mid-layer H6-8 cloud deck, lowering with time with
the approach of the surface low. Light and fluffy given the cold
air damming signature likely to remain, an initial 1 to 2 inches
is possible for the Hartford / Springfield metro with lighter
amounts elsewhere.
This storm is going to pack a whallop. E/SE winds increasing
towards morning as the low begins to bomb along the E CONUS
coastline. S-coast of New England will feel the initial brunt.
Expect a 995 mb low near the Delmarva Peninsula as we approach
6a.
In closing, if you can stay home, do so. Travel is going to be
bad Tuesday. It may seem benign at first but it should go down-
hill relatively quickly with plows unable to keep up. Visibility
will deteriorate down to a quarter mile or less in most places
with snowfall rates edging towards 2-4 inches an hour as we go
into morning.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY/...
Highlights on Major Winter Storm Tuesday:
* High confidence in 12-18" of snow west of I-495 corridor with
locally above 18 inches
* Less snowfall southern RI and southeast MA due to potential
changeover to rain
* Damaging winds along the coast
* Blizzard conditions possible west of I-95 corridor
Details on Major Winter Storm...
Expect high impact major winter storm for most of the region Tue
into Tue evening.
12Z model guidance continues westward trend of the rapidly
developing storm center. Most guidance suggests bringing the low
toward central Cape Cod or Nantucket, but a few are even
further W than that. Went along with model consensus with this
forecast package. System will remain progressive during its
rapid deepening, with heaviest precip occurring during Tue
morning and midday hours.
Timing and impacts...
Previous timing remains in place. Snow will start across N
CT/SW Mass into W RI by around 5 AM, then will push quickly NE
by 8 AM as the rapid deepening occurs. Very strong eastern low
level jet also associated with this system, which aids in the
development. Will see intense band of frontogenesis with strong
low level thermal gradient associated with the low. Expect this
band to bring very heavy snowfall rates Tue morning through
midday, with the most snow falling during this time. Would not
be surprised if thundersnow develops with such a dynamic system
moving across, with with heavy bands of snow that could produce
2-4"/hour.
Milder air will work in over the top of the system, bringing a
mixed bag of precip to eastern areas, which will lower snowfall
amounts. With excellent influx of tropical moisture from its
origins down the coast, QPF amounts forecast on order of 1.5 to
2 inches. So, could see areas of heavy rain where the precip
changes over Tue afternoon.
With the steady progression of the low, will start to see the
snow intensity lower during Tue afternoon/evening though with
moisture remaining, will see spotty light snow continue through
Tue evening.
Thermal profiles and snow-liquid ratios...
Latest guidance update has shifted the mean storm track to
along or just inland of the Cape Cod Canal, which has shifted
the warming trend slightly inland of previous runs although with
the suggestion for significant front end wet-bulbing effect
thanks to the still very low sfc-H85 dwpts. Therefore, still
expecting all snowfall except the immediate coastal areas at
onset and holding for the first 3-6 hours away from the
coastline until the lowest 100mb begin warming above. However,
this is again one of those cases where only a couple of degrees
in the lowest 50mb or so could make a significant difference in
totals, hence the tight gradient of snow totals from the Cape
Cod Canal through the I-95 corridor, including Boston and
Providence. This suggests a potential for last minute changes in
headlines. However, even as warmer air works in, drier air will
also be working in from S-N through the afternoon as a dry slot
so snow-liquid ratios will be dropping rapidly from late
morning into the afternoon due to both the low lvl
warming/drying aloft.
Strong winds and blizzard conditions...
Impressive low level easterly jet of 60-70 kts push N into S
coastal areas Tue morning, then will continue to push across the
remainder of the region into the afternoon. Decent low level
mixing suggests a good portion of the jet will mix down near the
immediate coast with gusts to 50-60 mph, strongest over the
Cape/Islands. Gusts to 40-50 mph expected further inland across
the interior RI and Interior eastern MA. The strong winds
combined with heavy snow will result in blizzard conditions at
times with best chance near and west of the I-495 corridor into
NE Mass where snow will be drier with greater potential to
produce whiteout conditions.
Snowfall...
Initially, at onset, snowfall rates will be relatively light
mainly due to a fair amount of dry air to overcome below H7 and
subsidence developing N of rapid banding development to the S as
the low pres rapidly deepens/occludes. After onset banding
potential is high as we note values of 20-25 microbars of lift
in the snow growth region during the morning hours and into
early afternoon especially, this is suggesting 2-4 inch per
hours snowfall rates for as much as 3-6 hours for some as the
bands shift from N-S. By afternoon, the combination of warmer
air moving into the I-95 corridor (suggesting a localized
coastal front adding to this) and a rapidly advancing dry slot
from about H7 and further aloft, ratios will be declining to
below 10 to 1 all locations except areas of N MA as the comma
head continues to develop. This doesn't mean snow completely
stops (except where it changes to sleet or rain), but that
snowfall rates will be declining through the afternoon as well.
Only portions of N MA, which may experience comma-head snowfall
(which could be intense as well in spots due to dry slot
instability noted on soundings). Will see more continuing into
the evening and overnight hours. This will part will become
better refined with time as there are timing differences even
know amount operational and ensemble guidance. Overall, looking
at widespread 12-18 inches across interior MA/RI and CT, with
ranges between 8 and 12 inches along the I-95 corridor, with
less toward the SE.
Given this Winter Weather Advisories and Winter Storm Warnings
are out for much of SE MA and RI, including the BOS-PVD
corridor. This is due to uncertainty in timing of the heaviest
snowfall with the peak winds which will be as the low lvl
warming and drying aloft begins. Blizzard Warnings, which may
need to be expanded are collocated with areas where all snow is
expected, even during the afternoon hours as snowfall rates
diminish and we watch the rapidly developing comma-head banding.
Headlines...
Converted to Blizzard warnings across NE Mass westward to near
and W of the I-495 corridor. Best shot for strong winds, causing
blowing and drifting of the snow that does fall, especially
well inland with higher snow-liquid ratio. Have kept Winter
storm warnings further east, where there will be somewhat milder
temps and a variety of mixed precip for a time Tue
afternoon/evening.
High wind warning for the Cape/Islands as well as along the
south coast and coastal Plymouth county.
Also continued Coastal Flood warnings from Plymouth county
southward to Cape Cod and the islands. Also added eastern Essex
county for the moderate coastal flooding potential around midday
Tue. Also kept Coastal flood advisories for Washington county RI
as well as for Suffolk county (Boston area).
Tue night and Wed...
The low pres will begin its occlusion process as it moves
slowly N through the Gulf of Maine. However, H5 cutoff system
will spin across the Great Lakes into NY/PA during this
timeframe. This will keep instability in the cold pool aloft
across the region. Will see a lot of clouds along with periods
of light snow or snow showers. Not much in the way of QPF, but
could see a dusting of snow here and there. W-NW winds will
remain brisk, gusting up to around 25-30 kt. Lows Tue night will
fall back to the teens across the interior and normally colder
spots, ranging to the lower-mid 20s across S coastal areas. It
will remain unseasonably cold on Wed with highs only in the 20s
inland, ranging to around 40 across S coastal areas. The inland
readings will run 15-20 degrees below seasonal levels.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Highlights...
* Below normal temperatures expected for much of this period
* Another chance for snow this weekend
Overview...
Models are in reasonable agreement through this portion of the
forecast. Moderate confidence in the overall pattern trends.
Deep closed low over New England should move farther north Thursday,
leaving a broad trough nearby through Friday. This trough is
expected to amplify once more heading into this weekend. If the
ingredients come together, it is possible for another storm to
impact our region.
At this point, very much prefer a consensus approach to smooth over
the less predictable details. Lots of time for things to change
between now and this weekend.
Details...
Wednesday night into Thursday...Powerful low pressure moves into the
Maritimes. This will result in gusty west to northwest winds. Strong
cold air advection may be offset some by downsloping across portions
of RI and eastern MA. Below normal temperatures expected, regardless.
Drier weather becomes more prevalent late Wednesday night into
Thursday.
Thursday night into Friday...High pressure nearby should mean dry
weather. West to northwest winds continue, so should the below
normal temperatures.
Friday night through Sunday...This will be the primary period of
interest during this portion of the forecast. Clipper-like low
pressure projected to impact our region. The track of this low
pressure will be crucial for precipitation type, which is especially
true this time of year. Have a broad window for precipitation
chances late Friday night into Sunday morning. This window will be
refined as we get closer to the event.
&&
.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Wednesday/...
No significant changes after 12Z tomorrow with 00Z update.
Overnight...High confidence.
VFR. Light E-SE winds and light winds prevail through around
06Z. Expect -SN to bring rapidly lowering conditions to IFR to
spotty LIFR along and SW of a KORE-KPVD line after 09Z. This
timing still looks good with the 00Z update.
Tuesday...Moderate confidence in expectation for widespread
IFR/LIFR. Lower confidence in changeover from periods of heavy
SN to rain at terminals along and E of the I-95 corridor.
Conditions quickly lower to IFR- LIFR in low CIGS, -SN. Areas
of SN/+SN develop across NE Mass and central- western areas by
midday. E-NE wind gusts up to 35-50 kt, highest across coastal
Mass and RI. Will see area of mixed RA/FZRA/PL develop across E
Mass after 18Z, changing over for a time across SE Mass/E RI.
Tuesday night...Moderate confidence. MVFR-IFR Tue evening, the
gradual improvement to MVFR conditions as precip changes back to
-SN and lightens later Tue night. N-NW wind gusts up to 25-35
kt.
Wednesday...Moderate confidence. MVFR conditions in periods of
-SN/-SHSN, improving across N CT during Wed afternoon. W-NW wind
gusts up to around 25 kt during the day.
KBOS TAF...High confidence. VFR through 09Z Tue. Snow and
increasing NE wind after 10Z. Periods of SN/+SN with IFR-LIFR
conditions after 12Z. Will see mixed -FZRA/-PL from around 19Z
to 23Z. E-NE wind gusts up to 40-50 kt likely after 17Z through
21Z-22Z.
KBDL TAF...VFR and light winds through 08Z Tue. Periods of
SN/+SN and areas of fog with LIFR conditions through most of
Tue. N wind gusts up to 30-35 kt around or after 16Z which
could cause blizzard conditions.
&&
.MARINE...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
High confidence through the period.
Tonight...Expect light S-SE winds backing to E. Winds will
increase after midnight, gusting up to 25-30 kt on the southern
outer waters.
Tuesday-Tuesday night...Storm warnings remain on all waters.
Expect E-NE wind gusts up to 50-60 kt with a few gusts up to 65
kt possible, highest on the waters just N and E of Cape Cod.
Seas will rapidly build up to around 18-23 ft, again highest on
the eastern waters with the onshore fetch. Will see reduced
visibilities in rain, snow and/or freezing rain/sleet.
Winds will back around to N-NW Tue night as the low moves into
the Gulf of Maine. May see residual gusts up to 40-45 kt near
and east of Cape Ann Tue evening, then should diminish to gales
overnight Tue. Precip should taper off and visibilities improve.
Wednesday...W winds will continue to gust to 35 kt early on the
eastern outer waters, otherwise, should see small craft conditions.
Seas remain high, up to 7-10 ft on the open waters for most of the
day. This may bring a chance of freezing spray.
Outlook /Wednesday Night through Saturday/...
Confidence...High.
NW gales likely continue early Wednesday, but should gradually
diminish to Small Craft criteria across most of the waters.
Much more tranquil marine conditions are anticipated for
Thursday and Friday.
&&
.TIDES/COASTAL FLOODING...
Models continue to signal a very strong low level easterly jet
developing Tuesday, with the highest winds at H95-H9 passing
across the eastern waters from late Tue morning through Tue
afternoon, coincident with the high tide cycle. Low level mixing
is not the strongest, but enough of mixing at H925-H95 to bring
down wind gusts up to 50-65 kt. Also expect seas up to 20-23 ft
Tue afternoon on the eastern outer waters, which will bring
high swells ashore.
Have added the Cape Ann/Plum Island area of Essex county to the
Coastal Flood Warning for Tuesday afternoon, given the strong
winds and high seas could bring moderate flooding to those areas
around high tide early Tuesday afternoon. Have also added a
Coastal Flood Watch for the late Tuesday night high tide. There
may be a strong NE jet working down toward Cape Ann from the NH
Seacoast as the low continues to explosively deepen over the
Gulf of Maine at that time. There may be minor coastal flooding
during that time. Have kept the remaining headlines in place,
including on Martha's Vineyard and for Washington county RI.
