NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
658 PM EST Thursday Nov 20 2014 


Synopsis... 
a cold front delivers a reinforcing surge of blustery and 
unseasonably cold conditions. The cold will linger through Friday 
night. A significant warm-up is in store Sunday and Monday...but 
it will likely be accompanied by a period of rain. Cooler weather 
returns by the middle of next week. 


&& 


Near term /until 6 am Friday morning/... 


Tonight...a cold front is moving across southern New England. 
Satellite images show a band of clouds along or just behind the 
surface wind shift. The clouds produced some flurries in the 
Berkshires...and radar at 645 PM showed light echoes from 
Manchester New Hampshire to the southern Berkshires...which might have a few 
flurries. These echoes should move across northern mass and 
southern New Hampshire and move to our east by midnight. 


Other concern tonight is the west low level flow bringing leftover 
lake effect moisture east from Lake Erie. Some of this may spill 
over the Berkshires into southern New England. Typically the bulk 
of any leftover moisture stops at the Berkshires. After the initial 
cloud band /noted above/ moves through...the forecast will expect 
patchy clouds mainly west of the CT river. 


Cold advection will bring colder air into the region with temperatures 
falling into the 20s most places. This advection will also draw 
gusty west winds down to the surface but a little lighter than we 
had during the day. Otherwise quiet weather. 


&& 


Short term /6 am Friday morning through Friday night/... 
Friday... 
cold day by late Nov standards with highs only in the 30s /normal 
high around 50/ and a brisk west-northwest wind will yield wind chills in the 
20s /teens higher terrain/! Gefs temperature anomalies indicate 850 temperatures 
over southern New England 18z Friday are about -2 Standard with values 
around -14c. So despite a well mixed blyr and at least partial 
sunshine and downslope wind component mu30s will be our maximum afternoon 
temperatures Friday afternoon. As mentioned above the brisk west-northwest winds will make 
it feel much colder. 




Friday night... 
dry weather prevails but another cold night with lows in the 
teens except 20s in the urban areas including Cape Cod and the 
islands. Not as much of a wind chill given the weakening pgrad 
with ridge of high pressure approaching from the west. 


&& 


Long term /Saturday through Thursday/... 
big picture... building upper ridge along the East Coast brings 
heights over New England back to normal during the weekend and above 
normal early week. Southern stream shortwave just off the Pacific 
coast will dig as it moves to Texas over the weekend. The building 
ridge will then deflect the southern shortwave north where it merges 
with a northern stream shortwave moving east from the Gulf of 
Alaska. This means a broad trough forming over the center of the 
nation early week with below normal heights. This broad trough 
slowly moves east to New England middle to late week. 


For New England this would mean a warming trend over the weekend and 
mild temperatures early next week...then cooling to below normal by 
Thanksgiving. 


The GFS and European model (ecmwf) are in good agreement through Tuesday. The ecwmf 
is then faster in migrating the plains trough through New England 
and off to the east while the GFS maintains the trough axis to our 
west through Thursday. Moderate to high forecest confidence through 
Tuesday...low confidence Wednesday and Thursday. 


The dailies... 


Saturday... high pressure will be in place during the day with the 
axis crossing during the afternoon. This should turn the wind 
southwest by afternoon. Increasing moisture aloft but expect most 
clouds to be middle and high level. With the developing warm advection 
aloft the mixing reaches only to 950 mb which would support maximum surface 
temperatures in the middle 30s to low 40s. 


Saturday night...increasing and thickening clouds as a northern 
stream cold front moves south into northern New England. Vertical 
distribution is somewhat favorable for precipitation ahead of the front...but 
warm advection lift is negligible. Jet dynamics is questionable. 
Can/T rule out a few light sprinkles. The question of ptype then 
comes up. Temperatures will be starting out in the 30s and may cool a 
little below freezing before the clouds thicken. This would cause 
some light freezing drizzle or freezing sprinkles. The best chance 
would be in areas north and west of I-495. But if the clouds move in 
and thicken a little faster...temperatures will stay above freezing and 
precipitation...if any...would be light rain. We have slight chance probability of precipitation 
across the region overnight with a mention of freezing rain as noted 
above. 


Sunday...upper flow remains west-east so that the northern cold 
front is doubtful to make it through southern New England. Expect 
any precipitation to move out early with clouds breaking to allow some 
sunshine. Temperatures at the top of the mixed layer warm a few degrees and 
should support maximum temperatures in the upper 40s and 50s. 


Sunday night-Monday... the southern stream system lifts north to the 
Great Lakes and pulls a warm front north toward New England. A 
strong low level south jet will generate favorable isentropic lift 
as it moves into the region. Timing of this jet would indicate the 
lift arrives around midnight or shortly after. We expect rain to 
develop in southern New England around this time. Models indicate 
the jet will be 60-65 knots and could generate some gusty winds 
especially along the South Coast. Precipitation water values are expected 
to top out between 0.75 and 1.0 inches which would be a little over 
1 Standard deviation above normal...so torrential rain is not expected. 


The warm front should lift north of our area during the afternoon. 
This should diminish the coverage of the rain to showers. The 
chance of showers will continue through the evening...ending as the 
associated cold front swings over the region overnight. 


Tuesday...there remains some question as to how fast the cold front 
moves off to the east. The GFS solution keeps a south-southwest 
flow aloft and a strong jet overhead. The cold front would have 
difficulty moving east in such an environment. The European model (ecmwf) solution 
shows a more westerly component that would be sufficient to move the 
front through New England and off to the east. We have kept a low 
chance of showers Tuesday in eastern mass but trended toward partial 
clearing and cooler weather. 


Wednesday-Thanksgiving day...the differences between models amplifys 
midweek...and so confidence is low. Low pressure waves moving up 
the offshore cold front may keep a chance of showers in eastern 
mass/Rhode Island on Wednesday but otherwise we have continued the trend to 
cooler and drier weather as we move into the Holiday 


&& 


Aviation /00z Friday through Tuesday/... 
forecaster confidence levels... 


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


Short term...high confidence. 


Tonight... 
west winds with gusts 20-25 knots. VFR but very low risk of brief 
MVFR conditions in an isolated snow shower across northern mass 
and southern New Hampshire. 


Friday... 
VFR but gusty west-northwest winds 20-25 knots. Low risk of brief MVFR 
conditions in an isolated snow shower. 


Friday night... 
VFR with diminishing west-northwest winds. 


Kbos terminal...high confidence. 


Kbdl terminal...high confidence. 


Outlook...Saturday through Monday... 


Saturday... 
VFR. SW wind 40 knots at 2000 feet...potential low level wind 
shear. Clouds move in at night...brief MVFR possible overnight in 
light sprinkles especially north of the Mass Pike. Could be light 
freezing drizzle/freezing sprinkles north and west of I-495. 


Sunday... 
VFR. Diminishing wind. 


Sunday night-Monday...cigs/vsbys lower to MVFR/IFR in rain/fog. 
South wind at 2000 feet increases to 60-65 knots along the coastal 
plain late night and Monday morning and may generate another round 
of low level wind shear in that area. Conditions then improve to VFR 
in the afternoon with gusty southwest winds. 


A cold front moves into southern New England at night and should 
generate brief MVFR in showers. Wind will shift from south-southwest to west-southwest with 
the wind shift. 


Tuesday...VFR. A few brief showers possible in eastern mass/Rhode Island 


&& 


Marine... 
forecaster confidence levels... 


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


Moderate forecast confidence through Friday night. 


Tonight...gusty SW winds become westerly with passage of secondary 
cold front. Wind speeds mainly 20-30 knots with low risk of isolated 
gusts to 35 knots. Long SW fetch has resulted in large seas on the 
southern waters with heights up to 8 feet. Other than isolated rain 
shower this evening/snow shower after midnight...mainly dry 
weather prevails. 


Friday...west-northwest winds up to 35 knots. Ocean effect snow showers well 
offshore. 


Friday night...west-northwest winds slowly ease. Despite subfreezing temperatures and 
modest west-northwest winds ocean temperatures still too warm for any freezing spray 
concerns with near shore water temperatures in the mu40s. 


Outlook...Friday night through Monday... 


Saturday... southwest winds increase with frequent gusts to 30 
knots. Seas build to 5-6 feet during the day and 5-8 feet Saturday 
night. A Small Craft Advisory will be needed. 


Sunday...southwest winds continue to gust to 30 knots during the day 
and then diminish in the evening. Seas 5-8 feet will diminish in the 
evening. 


Sunday night-Monday...a warm front moves up across the waters. 
Visibilities will lower to 1-3 miles in rain and fog starting around 
midnight and continuing into the morning. Strong south 
winds...roughly 60-65 knots...at 2000 feet altitude will move over 
the waters after midnight and through Monday morning. Some of this 
wind may be drawn to the surface in heavier bursts of rain. At the 
least...south winds will be near gale force for a time and then 
linger above 25 knots through Monday night. This will drive seas to 
5-10 feet on the exposed waters. 


Tuesday...southwest winds will gust near small craft thresholds. 
Seas will slowly diminish but remain above 5 feet on the exposed 
waters. Small Craft Advisory will be needed.
