NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
353 PM EDT Thursday Jul 30 2015 


Synopsis... 
showers and thunderstorms this afternoon and evening will give way 
to drier weather Friday...but it will remain very warm. Warm and 
humid conditions will return this weekend...then will become less 
humid with temperatures closer to normal next week. There is a low 
risk for scattered showers and isolated thunderstorms this weekend 
into early next week...however much of the time dry weather will 
prevail. 


&& 


Near term /until 6 am Friday morning/... 
355 PM update... 


* line of strong to possibly severe storms through 9 PM * 
* localized wind damage/flooding and perhaps an isolated tornado 


Mesoanalysis shows 1500-2000 k/kg of sb cape across southern New 
England with 25kt of 0-6km shear but meager middle level lapse rates. 
Line of storms has become more organized from SW Massachusetts across CT and 
into NYC area. So far heavy rain has been main threat but 
occasionally we have seen higher cores develop in some of the 
storms...so potential for localized wind damage and flooding will 
continue into this evening. 


Focus for storms looks to be across CT...northern Rhode Island and central/ 
eastern Massachusetts per high-res models. In particular hrrr shows evolution 
nicely although its timing is a couple of hours too slow. Line 
should reach Providence/Boston corridor 6-7 PM. 


Although very low probability...still cannot rule out an isolated 
tornado primarily as far east as Worcester Hills. Presence of 
30-35kt winds at 925 mb and low local from 70+ dewpoints points 
toward that potential. If one does occur... and that is a big 
if...it would likely be toward weaker side given strength of wind 
fields aloft. 


Activity diminishes tonight with loss of daytime heating and 
passage of cold front. Expect patchy fog to develop overnight. 


&& 


Short term /6 am Friday morning through Friday night/... 
front will be offshore Friday morning with drier and more comfortable 
airmass in its wake. Keeping Friday night dry although we should see 
increasing clouds as next short wave approaches. 


&& 


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


* expect more seasonable temperatures and lower humidity through most of 
this period 


* chance for a few showers/isolated thunder each day but much of the 
time remaining dry 


Synoptic overview and model preferences... 


Medium range forecast continues to feature anomalous 500 mb cutoff 
vortex across James and Hudson bays which will elongate across 
Quebec during the long term period. Will still see long wave trough 
across the eastern Great Lakes and down the Appalachians which will 
tend to flatten...though short waves will rotate around the base of 
the cutoff low into the mean trough. This will bring periods of 
showers/thunderstorms across the region from time to time. Not 
expected a total washout at any time...though models look like they 
may have some continuity will be around the late Monday/Monday night and 
Tuesday night timeframes. However...operational model solution spread 
does widens over time as one would expect especially this time of 
the year...so confidence in specific timing of convection and any 
short wave passage lowers. 


Used a blend of available guidance into Monday...then transitioned 
over to the GFS and ec ens means which gave a bit more continuity 
with previous forecasts. 


Details... 


Saturday...models continue to paint a weak 500 mb short wave in the mean 
upper flow for later Sat into Sat night. Looks like best instability 
and moisture...what there is of it...will be across central and 
western areas. Another question will be whether there will be some 
nocturnal instability showers/thunderstorms along the S coast where highest 
humidities are in place. Have left out for now...but it is signaled 
on the GFS model. 


Have generally slight chance probability of precipitation going...but may see a line of scattered 
showers/thunderstorms across CT valley into central Massachusetts/NE CT possible during 
the late afternoon/early evening. Expect the short wave to shift east 
and weaken so precipitation should also weaken overnight. 


Highs will generally be in the 80s. It will be cooler well inland 
late Sat night with lows around 60...ranging to around 70 along the 
S coast...Cape Cod and the islands. 


Sunday...weak surface ridge builds across so expect a mainly dry 
day. 850 mb temperatures will be from +15c to +16c...which will translate to 
the 80s for most areas...a bit cooler along the S coast with the S- 
SW winds in place. 


Monday...southwest wind flow remains in place. Models signaling a 
possible pre frontal trough approaching late Monday or Monday night 
/timing in question/. May see widely scattered showers/isolated thunderstorms across 
central and western areas...with the best chance across west Massachusetts and West 
Hartford County. With the milder S-SW flow in place...expect highs 
mainly in the 80s. 


Tuesday...W-SW flow aloft as Quebec vortex broadens. Another short 
wave and associated cold front looks to approach late Tuesday into Tuesday 
evening. GFS most aggressive in digging 500 mb trough to the west which 
will keep warm and humid air in place. Have carried chance probability of precipitation 
across the region...then should push offshore Tuesday night. 


Wednesday-Thursday...a lot of questions as to whether front will 
stall S of New England during this timeframe and if waves will move 
along this front. For now...have chance probability of precipitation moving across Wednesday 
night/Thu...but timing is still very much in question. Low 
confidence during this timeframe due to timing differences. 


&& 


Aviation /20z Thursday through Tuesday/... 
forecaster confidence levels... 


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


High confidence through Friday night. 


Line of showers/thunderstorms with MVFR/IFR arrive in west New England 18z- 
20z and should weaken before reaching coast 21z- 00z. Heavy rain 
main threat but potential for 40-50kt gusts in stronger storms. SW 
winds gust to 25kt especially near S coast. 


MVFR/IFR ceilings should return to parts of a coast...Cape Cod and 
islands this evening. Could also see patchy IFR due to valley fog 
inland. VFR Friday and Friday night with west/SW winds...may have local 
sea breezes during afternoon near coast. 


Kbos terminal...high confidence in taf. Main window for thunderstorms 
22z-00z. Heavy rain/lightning main hazards. 


Kbdl terminal...high confidence in taf. Main window for thunderstorms 
through 21z. 40kt gusts possible in stronger storms. 


Outlook /Saturday through Tuesday/...moderate confidence. 


Expect generally VFR most of the time. Low chance of scattered showers/ 
isolated thunderstorms Sat afternoon/early Sat night and again Mon-Tue. 
Brief local MVFR in any precipitation. 


&& 


Marine... 
forecaster confidence levels... 


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


High confidence through Friday night. 


Small Craft Advisory remains posted for 20-30kt gusts this afternoon near shore as 
gradient tightens ahead of cold front. In addition...long 
southwest fetch will allow for seas to build to between 3 to 5 
feet across most open waters. Winds diminish this evening...but 
keeping Small Craft Advisory through tonight for the outer waters due to leftover 
swell. 


High pressure will build over region Friday and Friday night with light 
winds and diminishing seas. 


Outlook /Saturday through Tuesday/... 


Saturday-Sunday...SW winds may gust up to 20 knots Sat/Sat night then 
diminish. With long S-SW fetch...seas forecast up to 5 feet mainly on 
the southern outer waters. 


Monday-Tuesday...continued SW winds in place...which may gust to 20 
knots at times. Seas up to 5-7 feet on the southern outer waters. May see 
scattered showers/thunderstorms Monday night/Tue. 


&& 


Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
Rhode Island...none. 
Marine...Small Craft Advisory until 7 PM EDT this evening for 
anz230>234-236-251. 
Small Craft Advisory until 11 PM EDT this evening for anz235-
