NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
1011 PM EDT Sat Apr 18 2015 


Synopsis... 


Canadian high pressure brings much cooler weather tonight and 
Sunday. A coastal low delivers a wind swept soaking rain to the 
region Monday. Mild weather Tuesday along with a drying trend. 
Then middle- to late-week the trend will be toward much cooler 
weather along with the risk of scattered showers. 


&& 


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


10 PM update... 


High pressure building S out of Canada will allow for mostly clear 
conditions and winds to relax across a majority of the region. But 
a continued tight pressure gradient out over the waters against 
the departing middle- to upper-level disturbance will yield some 
strong north-winds across the east-waters likely to impact the cape and 
islands into the morning despite the strong inversion as indicated 
by the 0z Chatham sounding. 


In addition to some scattered clouds...expect north wind gusts around 
15 to 20 miles per hour into the morning hours diminishing thereafter as high 
pressure continues to build and the aforementioned system departs 
east. 


Spots across the interior likely to radiate out effectively. Will 
see lows drop down to around the middle- to upper-30s but would not 
be surprised to see a few locations by morning Register lows 
around the 30-degree mark. 


&& 


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


Sunday... 


High pressure and an upper level ridge will move over southern 
New England bringing beautiful...but cooler weather to the region. 
High temperatures will be in the upper 50s to low 60s much of the 
area. Exceptions will be the Connecticut valley where it will be a 
little warmer and the East Coast where it will be a little cooler. 


Sunday night... 


This will be a transition period as high pressure moves offshore 
and clouds start to build into the region. Low temperatures will 
fall into the middle 30s to around 40. 


&& 


Long term /Monday through Saturday/... 


Highlights... 


* Monday/Monday night...wind swept soaking rain 
* Tuesday...drying trend and mild 
* Wed-Fri...cooler with periods of showers middle to late next week 


Overview and model preferences... 
aah...springtime in New England. After many days of relatively 
pleasant weather the damper on many a great plan...a slow moving 
cutoff will develop just upstream of southern New England. The 
persistent cutoff over the SW will finally get phased with northern 
stream energy to form this deep meandering cutoff by late Monday. 
Negative trending ao/nao suggests a blocked flow regime...so this 
cutoff will be taking its time going anywhere. In fact...it/S 
prognosticated to start in the Great Lakes by late Monday...and only be 
across central and northern New England by Sat. In spite of this highly 
amplified and blocked flow pattern...there is fairly good 
agreement between models. Therefore...a blend of operational 
guidance should work well as a baseline for this forecast. 


Details... 


Monday into Tuesday... 
the first in a series of shortwaves will be developing in 
diffluent flow across New England during the morning hours on 
Monday. Moisture loading is from the top down however and moving in 
from the SW. The initial surface reflection Monday is an approaching warm 
front...veering wind profile through the layer and a building low level jet 
all point toward decent lift moving in from the west. Precipitable waters  of 2 Standard 
deviations from normal will combine with the S low level jet of 60-70kt to 
yield moderate rainfall by the afternoon...with the possibility of 
pockets of heavier rain thanks to moderate lapse rates above 700 mb. 
It may take until the middle morning hours for eastern portions of the forecast area 
on Monday to see precipitation at the surface as there is a very robust dry 
layer near the surface to overcome...but suspect all areas will see a 
soaking rain during the day-evening Monday. Although a modest break 
is possible late Monday night...an approaching cold front associated 
with low pressure shifting into Quebec ahead of the cutoff will likely 
yield a continuation of the precipitation into the day on Tuesday. Dry slot 
will be working its way around the system and into the region by 
late day Tuesday so suspect with cold advection an end to precipitation by 
Tuesday afternoon. Final totals are likely to approach 1.0 to 1.5 
inches although slightly higher amounts are possible in spots. 


Tuesday night into Wednesday... 
drier air and ridging between shortwaves should allow for a 
period of at least relatively dry weather across the region. 
However...with upper level cutoff slowly shifting east with time...will 
likely see a fair amount of clouds in a region where any leftover 
moisture is observed. Temperatures mainly near normal. 


Thursday and Friday... 
another two shortwaves will shift the upper level cutoff the east 
through the period settling just to the north. The combination of cold 
air aloft yielding modest upper level instability...increasing 
moisture and better focus for left as surface low pressure 
develops...expect a period of -shra across the region both days. 
However...not a washout this period as there will likely be period 
dry spells. Overall column moisture not as robust as the early 
week system. 


Sat... 
cutoff shifts east allowing stacked northwest flow and cold advection to 
develop over the region. The cold advection aloft may be such that 
low topped convective showers are observed in spite of the drier 
air shifting into the region. 


&& 


Aviation /02z Sunday through Thursday/... 


Forecaster confidence levels... 


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


Short-term /through Sunday night/...high confidence. 


VFR. Light north-flow overnight across the interior through remaining 
blustery across east-coastal New England / cape / islands with gusts 
around 15 kts. North-winds shift east and onshore during the day becoming 
light. Sky clear. By evening expect increasing clouds that will lower 
and thicken towards Monday morning with the potential of low-end 
VFR ceilings and -shra across the west with winds continuing to veer out 
of the S/southeast and increasing. 


Outlook...Monday through Thursday... 


Monday and Tuesday...high confidence. 
Period of rain/fog under east winds which may gust around 20 knots near 
the East Coast. Expect conditions deteriorating through the from 
VFR to IFR. 


Wednesday and Thursday...moderate confidence. 
Conditions improve on Wednesday...such that a period of VFR conditions 
should occur northwest flow. Showers on Thursday could yield periodic MVFR/IFR 
conditions. 


&& 


Marine... 


Forecaster confidence levels... 


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


Short term /through Sunday/... 


10 PM update...high confidence. 


Small-Craft Advisory is in effect till morning for all east-waters 
with the threat of blustery north-winds overnight which will gust 
around 20 kts subsequent of a tight pressure gradient as high 
pressure builds S up against the departing cold front and low 
pressure southeast and out to sea. 


Expect boating weather to remain quiet through Monday morning as 
high pressure sweeps across the waters. Will see winds relax 
towards morning veering out of the east...turning southeast into Sunday 
night and increasing ahead of a storm system anticipated for 
Monday. Expect the possibility of showers across the far SW-waters 
by Monday morning. 


Outlook...Monday through Thursday... 


Monday into Tuesday...moderate confidence. 
S flow will build across the region through much of the period. 
Gusts up to 30 knots with a few gusts to around 35 knots possible. Not 
confident enough in widespread 34+ gusts to issue a gale watch at 
this time...but it will be close. Will run Small Craft Advisory 
for late Sun night into Tuesday night as that looks likely. 
However...seas are likely to reach about 10-13 feet by Monday evening 
on the ocean waters. Low visibilities in rain/fog. 


Wednesday into Thursday...moderate confidence. 
Conditions improve somewhat by Wednesday...such that no headlines may 
be needed for a period. However...a slowly building swell and 20 
knots winds may yield another round of small craft advisories by Thursday. 


&& 


Tides/coastal flooding... 


Spring tides of 11.5-12.1 feet are expected starting late sun on the 
East Coast. The highest for bos Harbor occurs around midnight Sun 
night at 12.1 feet...however winds will be out of the S-southeast and seas 
will have not yet built offshore. Therefore...not expecting too 
much in the way of issues with this particular tide. 
However...following high tides Monday afternoon of 11.8 feet...surge 
may be a foot or more by this point with 14 feet seas and east flow 
gusting near 25-30 knots. Therefore...may need to monitor for a 
period of splashover during this tide cycle. Not confident enough 
to issue statements at this time...but it is Worth watching.
