NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
946 PM EDT Thursday Apr 24 2014 


Synopsis... 
winds diminish tonight as high pressure builds into New England 
from the west...providing chilly temperatures but then rebounding 
nicely Friday with mild conditions and light winds. Low pressure 
then brings rain Friday night into Saturday...followed by a drying 
trend Sunday and continuing into early next week along with seasonable 
temperatures as high pressure returns to the area. 


&& 


Near term /until 6 am Friday morning/... 
945 PM update... 
winds still gusty...especially east new eng but trend will be 
diminishing winds overnight as high pressure builds in from the west 
and the gradient relaxes. Clouds lurking just offshore have backed 
in over the Outer Cape and will gradually move back to the east 
overnight. Otherwise clear skies will prevail. 


Previous discussion... 
the combination of diminishing winds/clear skies and a very dry 
airmass with dew points in the teens and 20s will result in a chilly 
night across southern New England. 


A blend of all data sources yields mins tonight in the 30s 
regionwide...except upper 20s in the deeper interior valleys such 
as the CT River Valley. The other exception will be in the city of 
Boston...Cape Cod and the islands where winds will not completely 
diminish and keep min temperatures around 40. 


As for frost/freeze headlines...the growing season has only begun 
along the South Coast. Here across coastal Rhode Island and south coastal Massachusetts 
temperatures will dip into the m30s for a time from about 3 am to 7 am. 
This will be sufficient for widespread frost. Given growing season 
is already in progress here will issue a frost advisory. Did not 
include communities near Narragansett Bay as winds will likely not 
decouple here keeping temperatures in the u30s and l40s. Thus lower risk 
of widespread frost. 


Elsewhere/inland temperatures will be colder however no headlines given 
growing season for most locations doesn/T start until sometime in 
may. 


&& 


Short term /6 am Friday morning through Friday night/... 
Friday... 


Real nice day with light winds as high pressure crest over the region. 
Deep layer subsidence will provide lots of sunshine with strong April 
sun angle warming airmass into the low and middle 60s inland. Cooler 
along the coast with developing seabreezes but overall a nice day 
by late Apr standards and considering what the weekend and extended 
forecast offers. 


Friday night... 


Robust trough over the Southern Plains this afternoon continues 
moving eastward and arrives here Friday night. Models in very good 
agreement on this system...with parent low entering western New York 
early Sat...while secondary low spins up near Long Island New York. Rain 
overspreads western portions of CT and Massachusetts 8 PM to 2 am...then 
across Rhode Island and eastern Massachusetts 2 am to 8 am. A period of heavy rain 
possible given modest Atlantic inflow and jet dynamics toward 12z 
Sat. 


&& 


Long term /Saturday through Thursday/... 
highlights... 


* unsettled weather is expected on Saturday...low conf on washout 
* unseasonable temperatures and unsettled weather middle next week 


Models and confidence... 
12z synoptic pattern is in good agreement. However the ec is more 
progressive on pushing out the blocking pattern then the GFS. 
Overall continued focusing the forecast base on the ensembles as 
the deterministic guidance is still somewhat spread out. However 
with both the nao and ao forecasted to be negative and with the 
pna expected to be more positive...there is increasing confidence 
of a blocking/trough over the northeast allowing for more 
unsettled weather. 


Quick moving shortwave over the Great Lakes will move into the 
region pushing a double barrel low through New England by Saturday. 
These low pressure systems will evolve into a cut off upper level 
low which continue to influence the region by wobbling over the 
Maritimes into Monday. However a closed trough/low over The Rockies 
on Monday will eventually be forced eastward across the eastern US 
by Wednesday in a developing Rex block setup as warming ridges build 
strongly over the western US. 


Details... 


Saturday... 
a double Barrow low will move over southern New England on 
Saturday. As the first low moves through the deterministic models 
agree that heavy precipitation will occur Sat morning into the early 
afternoon hours thanks to good Atlantic moisture plume and descent 
jet dynamics. Believe that the heaviest precipitation will occur on the 
northwest portion of the low. As the first low moves through and the 
second shortwave moves into the region...another shot of 
precipitation...more showery weather... will move through during the 
evening hours. So there is a low probability that there may be a 
break in the precipitation on Saturday. During the evening hours the 
region loses the good moisture plume however...some of the 
moisture may move on the backside of the low. Yet the jet dynamics 
are not in favor for heavy rain...so have moderate confidence in 
more showery weather Saturday evening into the overnight hours. 
Guidance continues to indicate some elevated instability moving 
through on Saturday so have inserted isolated thunder for now. However 
focused more on the southern half of the region where the better 
parameters are located. 


As the surface low approaches...easterly winds will develop on 
Saturday resulting in a much cooler coast then originally though. 
Have drop temperatures down into the upper 40s to low 50s. However across 
the CT valley...if clouds break out then temperatures could soar into the 
middle 50s thanks to the high April sunshine. Any adjustments in the 
track of the low could cause changes in the temperatures. 


Sunday into Monday 
northerly flow will continue into Sunday keeping temperatures 
down in the low to middle 50s across the region. However with the 
strong low pressure system just offshore appears that there could 
be some lingering showers. 


Northwesterly flow will continue on Monday and Tuesday. Conditions 
look to be breezy on Monday with the departing low moving offshore 
and weak high pressure trying to move into the region...increasing 
the pressure gradient. Temperatures will be close to average. 


Tuesday into Thursday... 
blocking pattern appears to set-up over the region during the middle 
to perhaps the end of next week. As an upper level low wobbles 
across the Midwest...appears that a trough will set up over the 
northeast. This low will allow for easterly winds across the 
region as well as cloudy skies. Therefore have increasing 
confidence that temperatures will be well below average for this 
time of year and expect several rounds of precipitation. However have a 
low confidence on when exactly each round of precipitation will occur and 
where the heaviest will reside. For now...have increasing 
confidence that cool temperatures and unsettled weather will occur. 


&& 


Aviation /02z Friday through Tuesday/... 
low...less than 30 percent. 
Moderate...30 to 60 percent. 
High...greater than 60 percent. 


Short term /through 12z Saturday/...high confidence 


After 00z...VFR with a diminishing wind. 


Friday...VFR with light winds...seabreezes along the coast. 


Friday night...VFR to start then quickly lowering to MVFR with 
rain overspreading western CT/Massachusetts 00z-06z then into Rhode Island and eastern 
Massachusetts 06z-12z. Low risk of IFR toward 12z Sat. East-southeast winds 
may increasing up to 25 knots toward 12z Sat across Rhode Island and eastern 
Massachusetts. 


Kbos terminal...high confidence in taf. Moderate confidence on 
the timing of the sea breeze. 


Kbdl terminal...high confidence in taf. 


Outlook...Saturday through Tuesday... 


Saturday...moderate confidence. Mainly VFR. Brief periods of 
MVFR/IFR conditions in rain showers/fog. 


Sunday into Tuesday...low confidence. VFR. Some showery weather 
possible on the East Coast on Sunday. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Saturday/...high confidence. 


730 PM update.... 


Tonight... 
winds across the waters have diminished below 34 kts. However 
there are a few sites still at 33kts. Because the trend is 
downward due to the relaxing pressure gradient decided to convert 
gales to Small Craft Advisory for the remainder of the evening as well as into 
tonight. 


Friday...high pressure crest over the region yielding light winds with 
seabreezes near shore. Dry weather and good visibility. 


Friday night...rain overspreads the waters from west to east. Rain 
heavy at times toward sunrise Sat. Low risk of thunder south 
waters. As low develops south of Long Island east to southeast 
winds may increase to 20-30 knots toward sunrise Sat with strongest 
winds south of Nantucket and Marthas Vineyard. 


Outlook...Saturday into Tuesday... 


Saturday...low to moderate confidence. S winds and seas increase 
as a low pressure system approaches the waters. Visibilities may 
be reduced at times in rain showers. Small craft advisories may be 
necessary. Winds shift to the northwest as the cold front crosses the 
waters. 


Sunday...moderate confidence. North/northwest winds will increase as surface 
pressure gradient tightens over the waters. Seas will build in 
response. Small craft advisories may be needed. 


Monday into Tuesday...upper level low over the Maritimes will 
continue to keep pressure gradient tight keeping the winds up as 
well as seas. Small craft advisories may be needed through the 
period. 


&& 


Fire weather... 
expect dry conditions tomorrow however the winds will be 
light...around 10 miles per hour. Expect sea breezes along the coastlines.
