NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
358 am EDT Thursday Jul 2 2015 


Synopsis... 
a cold front will stalling near the South Coast today...before 
moving offshore tonight. Aside from a few showers late today and 
tonight over Cape Cod and the islands...and a spot shower near 
the South Coast on Saturday...dry weather prevails into early next 
week with gradually warming conditions. 


&& 


Near term /until 6 PM this evening/... 
a weak cold front stalls near the coast...but the atmosphere is 
fairly dry with limited to no instability. This will result in 
mainly some clouds and dry weather. The exception will be towards 
Nantucket...where clouds will increase and there is a low risk 
for a shower late as some moisture moves north ahead of weak 
frontal wave. Local seabreezes will keep temperatures lower along 
the coast...where they develop. 


&& 


Short term /6 PM this evening through 6 PM Friday/... 
weak front moves farther offshore tonight as a frontal wave 
passes by the benchmark. Majority of the rainfall will stay south 
of our region. However...there is a chance of showers toward 
Nantucket...with a lower risk of these showers reaching as far 
north as Cape Cod...and as far west as The Vineyard. 


&& 


Long term /Friday night through Wednesday/... 
highlights... 


* low chance of a shower on Saturday. 
* Gradually warming conditions into early next week. 


Overview and model preferences...amplified blocking flow pattern 
continues mainly across the eastern Pacific and western Atlantic under 
strong ridging...especially in the Pacific where the epo is 
forecast to continue to dive strongly negative. This leaves much 
of the Continental U.S. In a nearly zonal flow regime. Nearly...because very 
weak troughing is evident particularly as northern stream energy moves 
shifts through he northern periphery of the mean jet. However...until 
about the middle portion of next week...guidance continues to show 
southern New England under the influence of the western Atlantic ridging. 
So even with the passage of a shortwave this weekend...it looks to 
move through with little fanfare as soundings show dry/subsidence 
in place. With moderate agreement between operational GFS/European model (ecmwf) 
/some smaller scale differences exist/ a blend will be used 
through early next week. Beyond this...there is some significant 
uncertainty regarding a shift as the northern stream vortex regains 
control across the area...leading to a more unsettled pattern. 


Details... 


Friday night into Sat night...with a weak shortwave moving east from 
the Great Lakes and a stalled frontal boundary to the S...will 
likely see cyclogenesis of a weak low pressure center well to the S. 
This will also introduce ridge of higher Theta-E air which looks 
to remain to the west. For now...the best chance looks to remain near 
the S coast...closer to the developing low pressure. However...column 
remains mostly dry and suggests some influence of the ridge moving 
east of the region. So suspect only a few spot showers to contend 
with at most. Temperatures at 850 mb are around +10c...so suspect 2m temperatures 
to remain near seasonal normals. 


Sun into Tuesday...as strong northern stream shortwave continues to deepen 
across central Canada...the warm advection will lead to ridge 
amplification over the Great Lakes and New England. This will lead 
to fairly strong high pressure development which may lock in place for 
a few days of dry weather. However...it will be accompanied by 
moderating middle level temperatures and rising humidity particularly Monday and 
Tuesday. 850 mb temperatures increase to an average of +12c Monday...then closer to 
+14c by Tuesday. Therefore...away from coastlines /where sea breezes 
will limit warming/ expect temperatures warmer than early July normals. 


Middle-late next week...as mentioned above...because this is such a 
robust shortwave/cutoff that models are trying to develop...there 
is little agreement between them regarding timing/strength...and 
ensembles are little help. However...with fairly warm/humid 
conditions and an approaching shortwave...there will likely be a 
transition to a wetter and more unsettled pattern toward the 
latter half of next week.

Aviation /07z Thursday through Monday/... 
forecaster confidence levels... 


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


Through 12z...high confidence. Mainly VFR. Patchy MVFR/IFR in 
developing stratus and fog. 


Today...high confidence. VFR most areas. But MVFR ceilings/visibilities may 
develop toward kack late...along with the threat of a few showers. 


Tonight...moderate confidence. Mainly VFR. Areas of MVFR/IFR 
possible Cape Cod and the islands. Showers likely for kack...possibly 
reaching the S coast and Cape Cod. 


Friday...high confidence. VFR. Sea breezes developing. 


Kbos terminal...high confidence in taf. 


Kbdl terminal...high confidence in taf. 


Outlook...Friday night through Monday... 


High confidence. Mainly VFR. Weak sea breezes likely most days. 


&& 


Marine... 
forecaster confidence levels... 


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


Lingering rough seas across portions of the southern coastal 
waters will slowly diminish today. So small craft advisories will 
persist over these waters for a while longer. Changeable winds as 
a cold front first stalls across the waters...then moves farther 
offshore tonight. Winds expected to remain less than 15 knots. Once 
seas diminish below 5 feet...expecting rather tranquil boating 
conditions through Friday. The main issue at that point would be 
reduced visibility in scattered showers and patchy fog. 


Outlook...Friday night through Monday... 


Friday night into Sat...moderate confidence. A week low pressure will 
pass well S of the waters. This may lead to east flow reaching 
20-25 knots on the southern waters and a building swell which could reach 
5-6 feet. Small craft advisories may be needed. Otherwise...some 
showers and fog at times may lead to reduced visibilities...mainly on the 
southern waters as well. 


Sun an Monday...high confidence. High pressure will move over the waters 
allowing and remnant swell to subside. After which quiet boating 
weather will prevail.
