Severe Weather Alert Descriptions

 Winter Storm Watch  Statement as of 4:21 PM EST on February 6, 2016


... Winter Storm Watch in effect from Monday morning through
Tuesday morning...

The National Weather Service in Taunton has issued a Winter Storm
Watch... which is in effect from Monday morning through Tuesday
morning.

* Locations... southeast Massachusetts including Cape Cod and the
islands. This includes the cities and towns of Brockton...
Plymouth... Mattapoisett... Chatham... Falmouth and Provincetown.

* Hazard types... snow.

* Accumulations... snow accumulation of 4 to 7 inches are possible
across the watch area Monday and Monday night.

* Uncertainty... the exact track of an ocean storm remains
uncertain. If the storm tracks closer to the coast heavier snow
amounts will be possible and farther inland. Conversely if the
storm tracks farther out to sea less snowfall can be expected.

* Timing... snow overspreads the watch area Monday morning and
afternoon... continuing through Monday night.

* Impacts... anyone traveling in the next 24 to 36 hours should
monitor later forecasts and be prepared to modify travel plans
should winter weather develop.

* Winds... northeast 20 to 30 mph with gusts up to 45 mph.

* Visibilities... may be reduced at times to a 1/2 mile or less.

Precautionary/preparedness actions...

A Winter Storm Watch is issued for the potential of accumulating
snow of 6 or more inches in a 12 hour period... or 8 or more
inches in a 24 hour period. Anyone traveling in the next 24 to
36 hours should monitor later forecasts and be prepared to modify
travel plans should winter weather develop.

 Coastal Flood Watch  Statement as of 4:27 PM EST on February 6, 2016


... Coastal Flood Watch in effect from Monday morning through Monday afternoon...

The National Weather Service in Taunton has issued a coastal Flood Watch...
which is in effect from Monday morning through Monday afternoon.

* Location... eastern Massachusetts coastline from Plymouth south
through Cape Cod including Nantucket.

* Coastal flooding... areas of moderate coastal flooding are
possible. Moderate coastal flooding produces widespread flooding
of vulnerable shore roads and/or basements due to the height of
storm tide and/or wave action. Numerous Road closures are
needed. Lives may be at risk for people who put themselves in
harms way. Isolated structural damage may be observed.

* Timing... the late Monday morning to midday tide cycle.

* Impacts... a coastal Flood Watch means that the potential exists
for moderate coastal flooding.

* Uncertainty... if the ocean storm tracks closer to the coast this
watch may need to be expanded northward.

Precautionary/preparedness actions...

A coastal Flood Watch means that the potential exists for moderate or major
coastal flooding. Moderate coastal flooding produces widespread flooding of
vulnerable shore roads and/or basements due to the height of storm tide and/or
wave action. Numerous Road closures are needed. Lives may be at risk for people
who put themselves in harms way. Isolated structural damage may be observed.

Major coastal flooding is considered severe enough to cause at least scattered
structural damage along with widespread flooding of vulnerable shore roads
and/or basements. Some vulnerable homes will be severely damaged or destroyed.
Numerous roads are impassable... some with washouts severe enough to be life-
threatening if one attempted to cross on foot or by vehicle. Some neighborhoods
will be isolated. Evacuation of some neighborhoods may be necessary.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
1002 am EST Sat Feb 6 2016 


Synopsis... 
high pressure brings dry weather this weekend with above normal 
temperatures by Sunday. Two developing coastal storms may bring 
accumulating snow Monday and Tuesday especially across eastern 
Massachusetts. An Arctic cold front brings much chillier air for the end of 
the week. 


&& 


Near term /until 6 PM this evening/... 


10 am update... 


No major changes to previous forecast. Confluent flow over the 
region today positions high pressure at the surface just south of New 
England. This will result in winds becoming west-southwest this afternoon and 
helping temperatures recover to 35 to 40. So other than adjusting hourly 
temperatures a bit previous forecast remains on track. 


Previous discussion... 


Weak upper level trough begins to set up over the region 
today. A passing high to our south will tighten the pressure gradient 
across the region for this afternoon. Anticipate gusts between 15-20 
miles per hour. Weak shortwave will will also bring some middle-level moisture 
into the area resulting in a filtered sunshine. Guidance does 
indicate temperatures in the upper 30s to low 40s but with the fresh 
snow pack that may be a bit to optimistic. 


&& 


Short term /6 PM this evening through 6 PM Sunday/... 
tonight... 


High pressure will mainly dominate resulting in quiet weather. 
However pressure gradient will be slow to relax which will limit 
radiational cooling overnight. Temperatures will drop into the 20s with 
perhaps low readings in areas where the wind will be calm. 


Sunday... 


Low pressure system to the north will drag a weak cold front through 
the region on Sunday. This front will be dry but may bring in some 
clouds. Westerly flow will dominate in the afternoon which will 
allow for temperatures to warm in to the 40s. Help aid in melting 
some of the snow. 


&& 


Long term /Sunday night through Friday/... 
big picture... 


Longwave pattern shows ridge west/trough east as before...with 
increasing amplitude early week and decreasing amplitude late week. 
Overall a cold and unsettled pattern for southern New England. At 
shorter wave scales we see three shortwaves affecting the pattern. 
The first is in the lower miss River Valley and generates coastal 
low pressure off the Carolinas Sunday. This swings wide of our 
area...crossing about 4 degrees south of the 40n/70w benchmark...and 
then sweeps northeast just south of Nova Scotia. The second 
shortwave is moving ashore in the Pacific northwest and will carve a 
deep cold trough over the eastern USA during the early week. The 
third shortwave is along the Arctic Ocean coastline and will drop 
south into the USA midweek. 


Operational guidance mass fields are similar on the broad scale most 
of the period. But there are differences in the details...especially 
regarding the second shortwave and its developing coastal system 
Tuesday. This second shortwave was just coming ashore at measurement 
time last night. The 12z Saturday models should have a better read 
on the shortwave and its effects. We continue to favor a model blend 
especially using the GFS and European model (ecmwf). 


The dailies... 


Sunday night-Monday... coastal storm passes well offshore...some 4 
degrees south of the benchmark. Normally that would mean a swing and 
a miss for strike three. But high pressure builds south from Quebec 
and establishes a pressure gradient that should bring a northeast 
marine flow with Delta of 13-15c. This should at least bring 
increasing clouds overnight and Monday. Less confidence on precipitation 
given mediocre forcing and changing run-to-run amounts. 


Models have backed off on quantitative precipitation forecast during Monday with main focus on cape 
and islands...possibly eastern mass. We have backed off onset of 
probability of precipitation until 06-12z Monday and value of probability of precipitation by about 20 percent. This 
still brings potential for several inches in eastern mass with 
highest amounts Cape Cod/Plymouth Colorado area. 


Monday night-Tuesday... second shortwave digs over the Midwest with 
surface low redevelopment along the middle Atlantic coast. This new 
coastal low then moves past New England. Better dynamics and 
resulting lift should be in place and with deeper moisture would 
expect this to be a better chance of precipitation than the Monday offshore 
system. But the responsible shortwave is just now moving ashore as 
noted above. So still some uncertainty with this system and its 
potential. We will bring a period of likely probability of precipitation as the system moves 
through. 


Wednesday through Friday... upper trough with its cold pool aloft 
and cloud shield linger Wednesday. The Arctic shortwave then swings 
through on Thursday. Expect quite a few clouds during this period 
with a chance of snow showers. Clipper low then drops southeast from 
northern Ontario Friday and bringing more clouds and scattered snow 
showers. Mixed layer reaches either side of 925 mb each day...a 
little higher Thursday behind the Arctic shortwave and surface 
front. Temperatures aloft at the top of the layer support 30s 
Wednesday...20s west/32 east Thursday...and 20s to near 30 Friday. 
As noted earlier...cold and unsettled. 


&& 


Aviation /15z Saturday through Wednesday/... 
forecaster confidence levels... 


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


Short term /through Sunday/... 


10 am update ... no major changes from 12z tafs. Previous 
discussion below. 


Today...high confidence. VFR. Winds shift to the SW. A few gusts 
between 15-20 miles per hour are possible in the afternoon. 


Tonight into Sunday...high confidence. VFR. 


Kbos terminal...high confidence in trends. 


Kbdl terminal...high confidence in trends. 


Outlook /Sunday night through Wednesday/... 


Two potential storms during this period...either could bring 
IFR/LIFR ceilings and visibilities in snow. The first chance for this will be 
Monday...with best chance on Cape Cod and islands. North-northeast 
winds will gust to 35 knots along the eastern mass coast. The second 
chance will be Monday night and Tuesday with all of southern New 
England under the gun. Conditions improve Wednesday to MVFR ceilings 
with scattered snow showers. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Sunday/...high confidence. 


10 am update ... no major changes from previous forecast. Chop 
seas develop this afternoon as west-southwest winds oppose easterly swells 
across the ocean waters of Rhode Island and Massachusetts. Earlier discussion below. 


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


Lingering swells and seas will begin to subside today. Small Craft Advisory lingers for 
a portion of the day...but may be able to be dropped sooner. 


High pressure will build over the waters through the weekend. An 
increase in the gradient will allow for some gusty winds across the 
northern waters late this afternoon into tonight. Seas will build in 
response. Small Craft Advisory may be needed tonight and into tomorrow for building 
seas in response to gusty winds. 


Outlook /Sunday night through Wednesday/...moderate confidence... 


Sunday night-Monday...a developing gale center will pass well 
offshore southeast of Nantucket...but strong winds will extend an 
unusual distance out from the weather system. Northeast winds over 
the waters will increase to gale force. This will build seas of 7 to 
11 feet on the exposed waters. A Gale Warning will eventually be 
needed for late Sunday night and Monday. Also expect reduced visibilities 
in rain and snow. 


Monday night-Tuesday...a second weather system will develop along 
the middle Atlantic coast and move outside Nantucket. This will bring 
another period of northeast winds with gusts over 25 knots. There 
remain many questions about this next system...as well as low 
potential for winds reaching 35 knots. Seas will remain at 7 to 11 
feet. 


Wednesday... winds diminish as the second coastal storm moves off. 
Wind speeds should go below 25 knots. Rough seas will linger much of 
the day especially on the southern exposed waters. 


&& 


Tides/coastal flooding... 
Monday... 


There is a fairly high astro tide of 11.2 in Boston late Monday 
morning. Northeast wind gusts of 30 to 40 knots from large 
circulation of the intensifying ocean storm will likely result in a 
1 to 1.5 surge. Seas should be built up to between 10 and 15 feet 
by then...so feel there is a decent shot for pockets of minor 
coastal flooding along eastern Massachusetts coast. There is a low risk for 
pockets of moderate coastal flooding...if the storms ends up a bit 
faster and tracking further west than current guidance indicates. 


Monday night and Tuesday... 


Main concern is if we end up with a second area of strong low 
pressure tracking up the coast...which could impact additional high 
tide cycles. Large spread in the guidance on whether or not this 
happens. If so...will have to watch the Tuesday noon high tide 
cycle across eastern Massachusetts as Boston has an 11.5 astro tide. 


&& 


Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
Rhode Island...none.
