NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
955 PM EDT sun Aug 30 2015 


Synopsis... 
mainly dry weather with hot conditions on Monday. A backdoor cold 
front will bring cooler weather Tuesday but mainly just to eastern 
New England... before unseasonably hot weather returns to most of 
the region Wednesday and Thursday. Another backdoor cold front 
should bring slightly cooler weather Friday into the Holiday 
weekend...but temperatures will still be above normal with mainly 
dry weather continuing. 


&& 


Near term /until 6 am Monday morning/... 
950 PM update... 
weakening showers moving along the South Coast will dissipate 
next hour or so as they move into the coastal waters and upper 
cape/mvy. A few showers also moving east from coastal CT. Low 
probability of a brief shower coastal Rhode Island around midnight...otherwise 
drier air moving in from the north will keep showers S of the 
region overnight. 


An abundance of middle level cloudiness this evening should begin to 
clear from north to south overnight. However...clouds may hang 
tough near the South Coast through daybreak. Low temperatures should 
range from around 60 in the normally cooler outlying locations of 
northwest Massachusetts...to mainly the 60s to around 70 elsewhere. Patchy 
ground fog will likely develop late in the typically prone 
locations. 


&& 


Short term /6 am Monday morning through Monday night/... 
Monday...low pressure moving from Quebec into the Maritimes will 
bring a weak cold front southward through Maine and into southern 
New England. Still seeing quite a bit of dry air across the region 
so am not expecting any rain and even a few diurnal clouds seem to 
struggle. Strong northwesterly flow aloft contributes to the dry 
air in the middle and upper levels but also brings warmer 850mb temperatures 
into the region. Expect high temperatures in the upper 80s to around 
90 for most locations. Onshore winds along the South Coast will 
keep the immediate coast a bit cooler with highs in the lower to middle 
80s. 


Monday night...the upper ridge and high pressure at the surface 
start to build into southern New England. Expect clear skies and 
with drier northwesterly winds...temperatures should radiate out a 
bit more. Expect lows in the 60s to around 70. 


&& 


Long term /Tuesday through Sunday/... 
highlights... 


* very warm on Tuesday except cooler eastern New England coast 
* unseasonably hot Wednesday and Thursday 
* a bit cooler Friday into the Holiday weekend but still above normal 
* mainly dry other then perhaps a spot shower/storm Thursday 


Details... 


All models and their ensembles continue to show strong upper level 
ridging in control of our weather right through next weekend. This 
means above to well above normal temperatures and mainly dry 
weather. We may see enough forcing to spark a few spot 
showers/thunderstorms sometime Thursday into Thursday evening with a backdoor 
cold front. However...odds are against any widespread meaningful 
rainfall given upper level ridging...so will keep probability of precipitation in the slight 
chance range for now. 


The exception from the well above normal temperatures will be Tuesday 
across coastal New England...when a backdoor cold front keeps highs 
mainly in the upper 70s to the lower 80s. However...the lower CT 
River Valley should still see highs in the upper 80s on Tuesday and its 
not out of the question that someone touches 90. 


The hottest weather look to be Wednesday and possibly into Thursday 
with 850 mb temperatures around 18c. This should allow highs in the upper 
80s and lower 90s and would not be surprised to see a few locations 
hit the middle 90s. 


Another backdoor cold front will cool temperatures down a few degrees Friday 
into Sat...especially across eastern New England. However...still 
expect temperatures to remain above normal right through the Holiday 
weekend given upper level ridging in control. 


&& 


Aviation /02z Monday through Friday/... 
forecaster confidence levels... 


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


High confidence through Monday night. VFR through Monday night 
other than late night/early morning patchy ground fog in the 
typically prone locations. 


Kbos terminal...high confidence in taf. 


Kbdl terminal...high confidence in taf. 


Outlook /Tuesday through Friday/...high confidence. 


VFR conditions through the period other than very late night/early 
morning patchy ground fog in the typically prone locations. A spot 
shower or thunderstorm or two is possible Thursday/Thursday evening...but 
odds are against anything widespread. 


&& 


Marine... 
forecaster confidence levels... 


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


High confidence. High pressure over the waters will keep winds 
and waves below small craft criteria. Quiet boating weather is 
expected. There is a low probability of a brief period of 5 foot 
seas on the southern waters late Monday into Monday evening. 


Outlook /Tuesday through Friday/...high confidence. 


Upper level ridge of high pressure will keep winds/seas below Small 
Craft Advisory thresholds through the period. Visibility should be 
good as well...so nice boating weather expected through next week. 
A backdoor cold front Tuesday and again sometime Thursday into Friday will shift 
winds to the east...but gusts should generally remain less than 20 
knots. 


&& 


Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
Rhode Island...none. 
Marine...none.
