NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
204 PM EDT Sat may 30 2015 


Synopsis... 
dry weather will continue for today thanks to an area of high 
pressure. A cold front will slowly move across the region 
Sunday...then stall south of New England early next week. This 
will bring a chance of showers and a few thunderstorms 
Sunday...and a period of rain early next week. High pressure 
brings dry weather for the latter part of next week. 


&& 


Near term /until 6 PM this evening/... 
2 PM update... 
convection firing across East New York early this afternoon in axis of 
greatest instability and moisture. Further east across west new 
eng...MLCAPES of 500-1000 j/kg have developed but ki values are 
less than what is observed over East New York...mostly less than 30 
indicating less moisture. Ki values are forecast to increase a 
bit so cant rule out an isolated shower/thunderstorm in west Massachusetts and hrrr 
continues to suggest isolated convection. 


Stratus and fog confined to S coastal waters and islands and 
lifting north so areas of low clouds/fog possible along the immediate 
S coast and Cape Cod. 


Previous discussion... 
the main forecast question is extent of any convection this 
afternoon. Middle level ridge remains just off the coast which will 
slow cold front as it moves through the Great Lakes and stabilize east 
half new eng. Main focus for convection will be across upstate New York 
and Vermont in higher Theta-E axis and better instability. Models do 
generate marginal instability in west new eng with convective available potential energy 500-1000 
j/kg but 0-6km shear is quite weak. Hrrr shows a few isolated showers 
developing in the west this afternoon and will keep slight chance 
probability of precipitation west Massachusetts for a brief shower/thunderstorm this afternoon...but most of the 
area will remain dry. 


High temperatures will reach the low to middle 80s across much of the 
region away from the S coast with warmest temperatures in the upper 80s 
likely across interior NE Massachusetts. Otherwise 70s near the S coast due 
to gusty SW flow. In fact...soundings support wind gusts to 25-30 
miles per hour today. 


&& 


Short term /6 PM this evening through 6 PM Sunday/... 
tonight... 


Noticed guidance continues to slow down the frontal passage...so 
have adjusted the forecast to account for this trend. 


The cold front will begin to approach the region 
tonight...bringing some much need rainfall to the region. As the 
front approaches guidance indicates that showalters will be below 
0 with k values above 30c. Therefore cannot rule out some 
embedded thunder overnight. Area that will see the higher rainfall 
amounts will be north of the Pike...especially north of Route 2. 


Since the front will still be northwest of the region...anticipate 
another round of fog to develop along the South Coast/cape and 
islands as moisture pools along the front. Low confidence if it will 
be dense or not. 


Tomorrow... 


Timing of the cold front is still in question as latest guidance 
trend is to slow down the front. Regardless believe that the front 
will cross southern New England on Sunday bringing some much needed 
rain. Guidance still shows elevated thunder parameters...so will 
continue to mention thunder in the forecast...but strong to severe 
storms are not expected. 


Both the NAM and GFS indicate good boundary layer moisture along the 
front as is begins to stall over the region. With precipitable water values around 
1.6 inches and the front becoming aligned with the upper flow 
aloft...could see the potential for heavy rain and flooding due to a 
slow storm motion. Because of the uncertainty on where the front 
will stall...held off on issuing any sort of Flood Watch at this 
time. Right now believe that locations along and north of the Mass 
Pike will see the higher precipitation amounts on Sunday. Perhaps it will 
push Worcester out of the top 5 driest Mays on record. 


&& 


Long term /Sunday night through Friday/... 
overview and model preferences... 


Quite a change in the solutions of the 30/00z guidance from those 
just 24 hours ago. The trend has been for a significant slow-down 
of a cold frontal passage Sunday night into Monday. Some minor 
differences remain...but it was noteworthy that just about all of 
the guidance latched on to this slower timing. Models have also 
come into better agreement with their handling of a middle level 
trough early next week. More ridging returns for late next week. 


Favored a model consensus solution for this forecast update to 
smooth over the minor differences...where possible. 


The dailies... 


Sunday night through Tuesday...differences among the models on 
timing a frontal passage...but all move it to the South Coast of 
New England by Sunday evening. This front then should align with 
the upper flow and stall. A shortwave moving through the Great 
Lakes is forecast to generate a wave along this front...which 
crosses the Appalachians Monday and passes south of New England 
Tuesday. This low pressure...along with high pressure over eastern 
Canada...should bring a cool northeast flow to the region Monday 
and Tuesday. Meanwhile a southwest flow continues aloft... 
providing both lift and moisture. We will maintain likely probability of precipitation 
Monday...diminishing to chance probability of precipitation by late Tuesday as this low 
moves east. 


Wednesday through Friday...high pressure builds at the surface 
and aloft...bringing dry weather to southern New England. Light 
winds will favor local seabreezes during the daylight hours. 
However...the increased sunshine will favor a gradual warm-up 
across the interior each day. 


&& 


Aviation /18z Saturday through Thursday/... 
forecaster confidence levels... 


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


Through 00z...mostly VFR...but areas of IFR stratus/fog possible 
along immediate S coast and islands. Low risk of a spot shower/ 
thunderstorm across western Massachusetts. 


Tonight...moderate confidence. Expect IFR/LIFR stratus and fog to 
develop along the S coast this evening then slowly spread northward 
across southern New England. Fog will be mainly confined to the southeast coastal new eng 
with areas of MVFR/IFR ceilings will expand north across much of the 
region overnight. A few showers and possible a thunderstorm developing 
overnight in the interior. 


Sunday...moderate confidence. Widespread MVFR/IFR conditions. 
Numerous showers and thunderstorms developing as cold front drops S across 
southern New England. Main focus will be near the Mass Pike. Winds shifting from SW 
to NE behind the front with g25 knots possible NE Massachusetts in the 
afternoon. Timing of front...15-18z along and north of Mass Pike 
reaching S coast 21-00z. 


Sunday night...moderate confidence. Widespread MVFR/IFR 
conditions. Showers likely...especially interior. 


Kbos terminal...moderate confidence in taf. IFR conditions likely 
develop Sun afternoon as winds shift to NE behind the front. 


Kbdl terminal...moderate confidence in taf. 


Outlook...Monday through Wednesday...moderate confidence. 


Monday through Tuesday...MVFR/IFR ceilings and visibilities...most likely 
over the coastal plain and along the eastern slopes of the 
Worcester Hills. Showers possible through both days. 


Wednesday...VFR with a light north-northwest wind. Local 
seabreezes possible. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /today through Sunday/... 


Today...moderate to high confidence. Excellent mixing over the 
land will generate near shore small craft wind gusts of 25 to 30 
knots this afternoon. In addition...southeast swell will generate 
5 foot seas across the outer-waters. Therefore...small craft 
headlines posted for all waters. Areas of fog should improve 
somewhat by afternoon. 


Tonight...moderate to high confidence. Near shore small craft 
wind gusts should diminish by the evening. However...5 foot swell 
will continue across the outer-waters. Areas of dense fog 
possible tonight. 


Sunday...moderate confidence. May need to extend Small Craft Advisory for cold air advection 
behind a passing cold front from the north. Otherwise expect 
showers with embedded thunder could occur ahead of the front during 
the afternoon hours. 


Outlook...Sunday night through Wednesday...moderate confidence. 


Monday-Tuesday...Small Craft Advisory may be needed...especially 
on the eastern coastal waters. Northeast winds gusting up to 20 
knots...and perhaps a few gusts to 25 knots...each day. Seas 5 to 8 
feet on the eastern Massachusetts waters...and 3 to 5 feet on the southern 
waters. 


Wednesday...a Small Craft Advisory may be needed...mainly on the 
eastern waters. Diminishing northeast to north winds. Seas of 5 feet 
may linger on the eastern waters. 


&& 


Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
Rhode Island...none. 
Marine...Small Craft Advisory until 10 PM EDT this evening for 
anz230>237-251. 
Small Craft Advisory until 3 PM EDT Sunday for anz250-254>256.
