Severe Weather Alert Descriptions

 High Surf Advisory  Statement as of 10:06 am EDT on September 22, 2014


... High surf advisory remains in effect until 6 PM EDT this
evening...

* location... ocean exposed beaches of the South Coast including
the cape and islands.

* Surf height... 5 to 10 feet.

* Timing... into this evening.

* Impacts... high risk of dangerous surf and rip currents. Also
viewers of large surf should be in safe areas well away from
possible splash over. Large waves can sweep a person into the
water from what may seem to be a safe viewing area.

Precautionary/preparedness actions...

A rip current... sometimes mistakenly called an undertow... is a
strong but narrow current of water flowing from the beach to the
surf zone. It can rapidly carry a swimmer into deeper water and
exhaust an individual trying to swim against it.

If you are a poor swimmer and are caught in a rip current... swim
parallel to the beach until out of its pull. Another means of
escape for those who are good swimmers is to ride the current out
beyond the surf zone where the rip current dissipates... then swim
toward shore outside the effect of the narrow rip current.

Do not attempt to swim back to shore directly against the
current... it can exhaust and drown even the strongest swimmer.

Heed the advice of the beach patrol and swim only at guarded
beaches. Watch your children. Be especially cautious near piers
and jetties where rip currents can be enhanced.

In addition... viewers of large surf should be in safe areas well
away from possible splash over. Individual waves may be more than
twice the significant wave height... which can sweep a person into
the water from what may seem to be a safe viewing area. Falling
into the turbulent and sometimes Rocky Waters can result in
injury that reduces the chance of survival.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
951 am EDT Monday Sep 22 2014 


Synopsis... 
a drier and less humid airmass overspreads the region today behind 
a departing cold front this morning...with breezy conditions and 
a mix of sun and clouds. This airmass remains over the region much 
of the week yielding mild days and cool nights. By weeks end temperatures 
begin to warm with possible record warmth next weekend. 


&& 


Near term /until 6 PM this evening/... 
945 am update... 
cold front offshore with gusty west wind ushering in much drier 
airmass as dewpoints fall through the 50s and into the 40s. 
Diurnal cumulus expected with greatest coverage in the interior. Strong 
low level cold air advection...especially west will keep temperatures in the 60s but 
reaching into the 70s in the coastal plain where stronger cold air advection is 
delayed until after 18z. Good mixing will yield wind gusts to 
25-30 miles per hour with a few higher gusts over the elevated terrain. 
Current forecast on track so no major changes. 


A building offshore swell today...will yield high surf 
particularly at south coastal beaches today. Therefore...will 
continue high surf advisory. 


&& 


Short term /6 PM this evening through 6 PM Tuesday/... 
tonight... 
cool dry airmass settles in place as nose of strong 1035 hpa high 
pressure moves in from the west. In spite of this more autumn-like 
airmass...mins may not be able to realize their full potential. 
The combination of lingering diurnal cumulus early...and surface pressure 
gradient taking some time to fully slacken may limit radiational 
cooling. Lows in the upper 30s-middle 40s are likely...with mins 
closer to 50 in the urban spots. The coldest spots are likely in 
northwest Massachusetts and SW New Hampshire. It/S very close to frost thresholds...but with 
the mitigating factors mentioned...not confident enough to issue 
frost advisory at this time. This will have to be watched through 
the day. 


Tuesday... 
high pressure begins to crest across the region on Tuesday. 
Therefore...mostly sunny skies are expected. 850 mb temperatures hover 
around +6c...but may not be fully realized under strong 
subsidence inversion. Therefore...keeping highs generally a degree 
or two below normal. Mainly the middle 60s to around 70. 


&& 


Long term /Tuesday night through Sunday/... 
highlights... 


* the 1st week of autumn will feature mild days and cool nights 
followed by potential near record warmth next weekend 


* high pressure provides dry weather through the period 


Synoptic overview and model evaluation... 


Fairly strong teleconnection for ridging here in the east this 
coming week and next weekend as +pna trends toward neutral along 
with nao and ao trending or remaining positive. During this time the 
large scale flow evolves into a West Coast trough with a downstream 
ridge over the Great Lakes northward toward James Bay. This is a 
warm and dry setup for New England. However given the chaotic nature 
of the atmosphere there are always wildcards at this time range and 
this case is no exception. 


The first wildcard will be the downstream mean trough over the 
Maritimes. Will have to watch if any northern stream impulses 
climbing over the Great Lakes ridge and then into the Maritimes 
drags any backdoor fronts into eastern New England. This would yield 
cooler temperatures especially for eastern Massachusetts. The other wildcard will be 
moisture and jet energy that breaks off over the southeast states 
from the middle level trough moving across the eastern Seaboard today. 
Some of the deterministic guidance has this moisture/inverted trough 
creeping northward during this week and getting close to New England 
Wednesday night into Thursday night before then getting shunted out to sea Friday. 


Otherwise despite autumn arriving later today the subtropical ridge 
delivers one or more days of anomalous warmth to the region next 
weekend. The 12z ecens and 00z gefs have 850 temperatures warming to +14c 
across southern New England during this time. 


Daily sensible weather details... 


Tuesday night through Thursday... 


Dry airmass over New England along with light winds as surface ridge 
axis settles across the area will yield ideal radiational cooling 
conditions. This will result in chilly nights with most locations 
dipping into the 40s outside the urban areas and away from the 
coastline. However afternoon temperatures will recover nicely to 65-70. 
Given proximity of the surface high winds will be light with local 
seabreezes developing during the afternoon. Given the radiational 
cooling conditions will stray away from a model blend and follow the 
cooler MOS guidance and even shave off a few more degrees in the 
typically cooler locations /I.E. Norwood-Taunton-Marthas Vineyard- 
etc/. As mentioned above will have to watch moisture and inverted 
trough creeping up the coast Wednesday night through Thursday night. 00z gefs has 
trended north with low probs of 0.05 quantitative precipitation forecast along the South Coast. This 
supports the farther north solution of the operational 00z GFS. In 
addition a model blend of all datasets brings slight chance probability of precipitation to 
the South Coast with a model blend of quantitative precipitation forecast bringing measurable rain 
into northern CT-Rhode Island to southern suburbs of Boston. 




Friday/Sat and sun... 


Surface high shifts westward from over New England to across the 
Great Lakes. This yields a warmer west-northwest low level wind flow into New 
England. This should yield temperatures well into the 70s Friday and then 
pushing 80 or so next weekend. The records for the day include 


9/27... 


Bos...86...1998 
bdl...88...1998 
pvd...86...1998 
orh...85...1933 


Given the time range here along with degree of uncertainty will 
follow a model blend. Humidity should be in the comfortable range 
given west-northwest low Level Land trajectory. 


&& 


Aviation /14z Monday through Friday/... 
forecaster confidence levels... 


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


Short term /through Tuesday/... 


7 am update... 


Cold front now offshore with west winds at all terminals and VFR 
conditions. West winds gusts up to 25 knots today along with VFR 
conditions. 06z tafs capture these details so no major changes 
with upcoming 12z tafs. Earlier discussion below. 


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


Today into Tuesday...high confidence. 
VFR...although MVFR/IFR conditions may linger at ack through middle 
morning. Winds mainly west-northwest today...gusting to around 25 knots at 
times then diminishing overnight. 


Kbos terminal...high confidence for mainly VFR from now on. 


Kbdl terminal...high confidence for mainly VFR from now on. 


Outlook...Tuesday night through Friday... 


High confidence for VFR each day. Exception will be a low risk of 
MVFR in showers South Coast including the islands from Wednesday night 
through Thursday night. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Tuesday/... 


Today and tonight...moderate confidence. 
Slowly building swell may approach 10 feet well offshore...but 
increase to 5-8ft closer to the the southern New England coast through 
the day...as west-northwest winds reach about 25 knots. Therefore...small craft 
advisories have been issued and will continue into 
tonight...dropping close to shore this evening as winds 
diminish. However...the swell may take until early Tuesday morning to 
completely diminish on the S and southeast waters. 


Tuesday...high confidence. 
After the leftover swell subsides...a prolonged period of quiet 
boating weather is expected as high pressure begins to crest over the 
waters. 


Outlook...Tuesday night through Friday... 


High confidence... 


Light winds through the period as high pressure remains over or near the 
region. Dry weather and good visibility too. Possible exception will be 
rain showers Wednesday night through Thursday night as moisture advects up the 
eastern Seaboard.
