NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
716 am EST Wednesday Mar 4 2015 


Synopsis... 
weak low pressure will push along the stalled front with another 
round of snow tonight into Thursday. High pressure will build in 
for Friday through this weekend...bringing dry conditions with 
colder than normal temperatures. A weakening front may bring some 
light snow showers on Monday. 


&& 


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


700 am update... 
light rain continues to move across north CT/RI/se Massachusetts early this 
morning as it redevelops across east PA/southeast New York into New Jersey and shifts east 
in the general westerly upper flow. Cold front appears to have 
cleared the Berkshires and Vermont as winds have shifted to light west 
from kpsf-kaqw-kvsf at 12z. 


Temperatures did fall back a bit since 09z...mainly in the middle to upper 
30s at most locales at 12z...but should rise some as the low 
clouds are lifting allowing for some sun to break through. With 
cyclonic flow aloft though...lower clouds will fill back in by 
middle-late morning. 


Have updated near term forecast to bring conditions current. 


Previous discussion... 
expect the front will stall S of New England this afternoon as it 
becomes parallel to the west-SW upper level flow. Most of the 
steadier precipitation should shift to the S coast and islands...though 
could still see spotty light rain across areas S of the Mass Pike. 
Still a lot of moisture in the middle and upper levels so skies will 
remain mainly cloudy especially across southern areas. 


&& 


Short term /6 PM this evening through 6 PM Thursday/... 
short range models in good agreement on timing...though still 
some differences on placement of the stalled front S of New 
England. High res models /hrrr...WRF and rap13/ and as well as the 
00z NAM and European model (ecmwf) were in good agreement...with the 00z GFS a bit 
further north than the other models. Used a non-GFS blend for this 
forecast. 


Question remains how far north will the moisture from the approaching 
surface wave moving along the stalled front will go. Models still 
signaling a sharp north cutoff to the precipitation as it moves east-NE 
overnight...with the heavier precipitation remaining across S coastal 
areas. Kept Cat probability of precipitation going across S Rhode Island/S coastal Massachusetts and the 
islands...with likely probability of precipitation across north CT/most of Rhode Island into southeast Massachusetts. Did 
keep chance probability of precipitation going to around the Mass Pike then should be 
little if any precipitation north of there. 


Good slug of precipitation moves east across S coastal areas mainly after 
midnight through midday Thursday. Another question will be how quickly 
the cold air filters in. Looks like timing is similar to previous 
forecast...so expect temperatures falling below freezing after midnight. 
So...rain will mix with some sleet before changing over to snow 
during tonight. Plus...with periods of moderate snow...will 
likely see dynamic cooling late tonight into Thursday morning across S 
coastal areas. 


Expect total quantitative precipitation forecast tonight and Thursday to range from around 0.1 to 0.2 
inches close to the Mass Pike up to 0.5 to 0.8 inches across the S 
coast...Cape Cod and the islands. With the colder air working 
in...will see a good amount of snowfall...with the best shot 
across the islands. 


Feel confident that the islands will receive the highest snowfall 
from this passing system...so went with a Winter Storm Warning for 
those areas. Kept a watch going along the S coast for now as there 
is still a chance that they will also see 6+ inches of snow but 
still on the fence on this...may also be just below warning 
criteria. 


Expect steady precipitation to continue through a good portion of Thursday... 
though will start to diminish during Thursday afternoon as the low pressure 
wave moves by and the upper trough approaches. Precipitation should start 
tapering off from NW-se...though will linger across east Rhode Island/southeast Massachusetts 
through most of the day. 


&& 


Long term /Thursday night through Tuesday/... 
* high pressure builds in Thursday night...passing S Friday 
* moisture starved cold front moves through this weekend 
* uncertain forecast early next week 


Models are in fairly good agreement going into the weekend. There 
are some minor discrepancies in timing of a cold front through the 
weekend. Then next week they diverge a bit...with European model (ecmwf) attempting 
to bring a coastal low up over the benchmark Tuesday and the GFS 
bringing in a strong high pressure just south of southern New 
England. At this point...will opt for a blend of available guidance 
for the weekend into early next week to take care of some of the 
timing errors. 


High pressure builds in from the Midwest Thursday night...bringing 
an end to the snow. Then Friday...the high pressure becomes 
suppressed to the south as low pressure moves into Quebec. This 
will keep chilly temperatures...well below normal for early March... 
in place for southern New England. 


This weekend...a shortwave pushes low pressure through Quebec... 
allowing a cold front to move through southern New England. At this 
point...this frontal passage appears to be fairly moisture starved 
so little if any precipitation will accompany this front. Temperatures 
moderate a bit but remain well below normal. 


Early next week models diverge with radically different solutions 
for southern New England. Given the time frame...this is not 
completely unusual...so will take either model with a grain of salt 
at this time. Regardless of the model...it does look like 
temperatures continue to moderate into next week.

Today...SW winds gusting to 20-25 knots through midday then will 
diminish as they shift to west with frontal passage. Expect front to 
stall across the southern outer waters or possibly a bit further 
S. Small craft advisories may be dropped on the near shore waters 
around midday or early afternoon...but look to linger on the 
outer waters mainly for high seas. 


Tonight and Thursday...winds shift to northwest. Gusts up to 25 knots 
mainly on the outer waters tonight. Seas remain at or above 5 feet on the 
outer waters as well. 


Outlook...Thursday night through Sunday... 


High confidence. Winds and seas slowly diminish Thursday night 
and Friday as high pressure builds over the waters. They then 
increase but only modestly over the weekend as a cold front 
approaches then crosses the waters. Small craft advisories will 
likely be necessary on the outer waters for a portion of this 
time.
