The National Weather Service in Taunton has issued a blizzard
watch... which is in effect from Monday evening through late
Tuesday night.

* Locations... eastern Massachusetts and Rhode Island.

* Hazard types... heavy snow... strong winds and blizzard
conditions. Considerable blowing and drifting snow.

* Accumulations... snow accumulation of 18 to 24 inches.

* Timing... the worst of the storm will be Monday night through
Tuesday afternoon.

* Impacts... heavy snow and strong winds will result in the
potential for blizzard conditions with near zero visibility.
Along the southeast New England coast... the snow may be wet
enough to result in some downed tree limbs and power outages.
Travel may become impossible and life threatening across the
entire region. This has the potential to be a historic storm.

* Winds... north 20 to 30 mph with gusts up to 60 mph.

* Temperatures... in the lower 20s.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
922 am EST sun Jan 25 2015 


Synopsis... 
chilly and blustery conditions expected today. A major and 
potentially historic winter storm will affect the region Monday 
night into Tuesday night...travel may become impossible and life 
threatening. Drier weather follows Wednesday into early 
Thursday...but will have to watch for another chance of snow by 
the end of the work week. 


&& 


Near term /until 6 PM this evening/... 
920 am update... 
cold front approaching north Massachusetts will move south across the region 
through early afternoon. Cloud cover across southern New England will diminish this 
afternoon as good low level drying develops behind the front. Any 
leftover flurries will end followed by increasing sunshine. Maximum 
temperatures will likely occur around midday then slowly fall this 
afternoon. Blustery northwest winds developing in cold air advection pattern with gusts 
to 25-30 miles per hour expected. Wind chills are likely to dip back into the 
teens and 20s. 


&& 


Short term /6 PM this evening through 6 PM Monday/... 
tonight... 
weak nose of high pressure will crest across the region...associated 
with a cold airmass. This cold blocking high pressure will be the 
feature needed for the early week storm. The weakened pressure 
gradient could allow for some radiational cooling...but increasing 
cloudiness from the SW are likely to limit ability to radiate. In 
any case...the increase in snowpack across the region should still 
yield a cool night. Suspect some areas do dip below 0f in northwest 
valleys...while the rest of the area falls back into the teens. 


Monday... 
high pressure slides itself into place to the north during the morning. 
Given it/S placement and location...and the fact that it is 
associated with dewpoints starting in the low teens and single digits 
Monday morning...like the slower timing of precipitation displayed by the 
NAM/ECMWF. Therefore...only bring categorical probability of precipitation into the mix 
by the evening timeframe Monday...suggesting that it will take some 
time for snows to begin reaching the ground during the day on Monday. 
Otherwise...expect only light accums by before Monday night mainly 
across CT...SW Massachusetts and S Rhode Island. MOS highs likely a bit too warm given 
the indication of wet bulb processes...so went a bit cooler. Winds 
begin to pick up toward evening as well...but strongest winds are 
not expected until later in the forecast. 


&& 


Long term /Monday night through Saturday/... 
highlights... 


* major to potentially historic winter storm Monday night into Tuesday night 
* blizzard watch eastern Massachusetts/Rhode Island 
* 1 to 2 feet of snow for many areas - locally higher amts possible 
* damaging winds possible coast especially cape/islands - gusts 60 to 70 miles per hour 
* significant coastal flooding possible along the eastern Massachusetts coast 


Details... 


This is pretty much a text book case for a major winter 
storm/blizzard in southern New England. Potent shortwave dives 
southeast closes off south of Long Island as low pressure bombs out 
and tracks up the New England coast. The highly amplified pattern 
will allow for a slow moving/long duration storm. In 
addition...high pressure across eastern Canada will supply plenty of 
cold air for the storm to work with so ptype will probably only be a 
concern for the far southeast New England coast. 


We are now quite confident that this will be a major winter storm 
and it has the potential to become historic for some locations. 
Will break down the various hazards in the next view paragraphs. 


1) heavy snow/blizzard conditions/wind and ptype 


The middle level low/S are closing off just south of southern New 
England Monday night and Tuesday. That will probably put US near 
ground zero for the heaviest snow. The models are in very good 
agreement in showing 1 to 2 feet of snow for much of the region. Of 
course there may be areas that exceed 2 feet where localized banding 
sets up...but its too early to worry about that. Very strong 
pressure gradient with 1035 mb high over eastern Canada and bombing 
surface low will likely result in strong to damaging northeast wind 
gusts of 45 to 60 miles per hour across eastern MA/RI. Gusts between 60 to 70 
miles per hour expected across the cape/islands! 


Will issue a blizzard watch for much of eastern Massachusetts/Rhode Island for 1 to 2 
feet of snow and 40 to 60 miles per hour wind gusts. This looks to be a 
serious winter storm and travel will likely become extremely 
difficult to impossible with near zero visibility. Considerable 
blowing and drifting snow also expected. 


Across central and western Massachusetts/northern CT have issued a Winter Storm 
Watch for 12 to 24 inches of snow. Its possible we may have to 
upgrade some of that region to a blizzard watch/warning...but was 
uncertain how much wind would mix down across that region and its 
still a late 4th and 5th period event. We are also leaning towards 
the western envelope of solutions at this time led the consistent 
European model (ecmwf). If the storm trends east a bit...we may be overdone with our 
snow accumulations across our western zones so something for later 
shifts to watch. 


The cape and islands present the most challenging forecast. 
Depending on exact track of the storm...portions of the region may 
mix with or change to rain for a time. If colder solutions verify 
there will be blizzard conditions...but if it ends up warmer could 
be a fair amount of rain. Therefore...will hoist a winter storm 
and high wind watch. In fact...we like going with the high wind 
watch here for the potential of 60 to 70 miles per hour winds. This may 
combine with any wet snow to cause downed trees and power outages. 


2) timing: 


The worst of the storm looks to occur Monday night into Tuesday 
afternoon. At least snow showers will likely linger Tuesday night 
as the system becomes vertically stacked and very slow to depart the 
region. Dry weather should finally work into the region sometime 
Wednesday morning. 


3) narrow swath of damaging wet snow 


Will have to watch for a narrow swath of heavy wet snow along the 
southeast New England coast. This could be problematic in terms of 
downed trees and power outages...especially given the strong winds. 
It may be a small area just northwest of the rain/snow line...but 
may have a significant impact. 


Wednesday through Saturday... 


While the storm comes to an end early Wednesday morning and the cleanup 
begins...we may be dealing with another winter storm later Thursday or 
Friday. 


&& 


Aviation /14z Sunday through Thursday/... 
forecaster confidence levels... 


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


Short term /through Monday/... 


Through Monday...high confidence. 
Mainly VFR. A few low clouds dissipate early today giving way to 
mainly middle and high clouds which will clear by tonight. 
Precipitation and lower categories will likely take until very 
late in the day on Monday. 


Kbos taf...high confidence in taf. 


Kbdl taf...high confidence in taf. 


Outlook /Monday night through Thursday/... 


Monday night and Tuesday...moderate to high confidence. Heavy snow 
and strong winds along the coast will result in IFR to LIFR 
conditions. Blowing and drifting snow is also expected. Northeast 
wind gusts of 45 to 60 knots expected along the coast. 


Wednesday...moderate confidence. Conditions to improve to VFR from 
west to east...but timing in question. North-northwest wind gusts up to 25-30 
knots possible early along the coast. 


Thursday...low confidence. Timing of low pressure and next chance of 
snow later Thursday or perhaps Friday. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Monday/...high confidence. 


Winds and seas remain elevated today as a cold front crosses the 
waters. Therefore...small craft advisories remain in place through 
this evening for all waters...and into the overnight for the ocean 
waters. Conditions improve briefly early Monday ahead of an 
approaching storm for Monday night into Tuesday. 


Outlook /Monday night through Thursday/... 


***life threatening storm for mariners with seas building to over 25 
feet and winds gusts to 60 knots Monday night into tuesday*** 


Monday night through Tuesday night...moderate to high confidence. 
Rapidly intensifying low pressure moving across the waters will 
combine with high pressure across eastern New England. This will 
result in northeast wind gusts increasing to 50 to 60 knots and 
building seas to over 25 feet across our eastern waters. Storm 
watches posted and low probability that we may need hurricane force 
wind warnings! This is dangerous and life threatening storm and 
mariners should return to port by Monday afternoon. 


Wednesday...moderate confidence. Should see at least leftover north-northwest 
wind gusts up to small craft criteria during Wednesday...then should 
diminish Wednesday night. 


Thursday...low confidence. Winds should remain below small craft 
criteria. Seas may linger at around 5 feet. 


&& 


Tides/coastal flooding... 
a significant coastal flood event is possible along the eastern Massachusetts 
coast during the early Tuesday morning and late Tuesday afternoon 
high tide cycle. Northeast wind gusts between 45 and 60 knots will 
seas building to over 25 feet across our eastern outer waters. 
Astronomical high tide is 10.5 feet in Boston on Tuesday at 430 am. 
The potential for a 3+ foot storm surge may result in moderate to 
isolated pockets of major coastal flooding. Another high tide will 
have to watch closely occurs late Tuesday afternoon/early evening 
since seas will be built up. In addition...significant beach 
erosion is possible. 


A coastal Flood Watch has been issued for eastern Massachusetts including Cape 
Cod and Nantucket.
