NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
654 am EDT Wednesday Oct 1 2014 


Synopsis... 
cool...damp conditions remain in place into Thursday morning...with 
more widespread rainfall expected today. Dry weather returns later 
Thursday into Friday as high pressure builds back across the region. 
A cold front will move across New England later Saturday afternoon 
and early Saturday night...followed by cooler and drier conditions 
for Sunday and Monday. 


&& 


Near term /until 6 PM this evening/... 


7 am update... 
upper level low pressure moving toward New England with core 
moving overhead this afternoon/evening. Bands of showers rotating 
around the center of this low are moving southeast to northwest across southern 
New England. As the low shifts farther east today this movement 
should become east to west. We have expanded the area of likely 
probability of precipitation and made a few adjustments to temperatures. Otherwise...continue the 
wet forecast for southern New England. 


Previous discussion... 
an upper level low over Pennsylvania moves eastward over southern 
New England today. Combined with the low pressure system well 
southeast of Nantucket...an inverted trough should develop just 
west of southern New England. This will create a deep layer of 
lift that will allow rain to become widespread across the region 
today. Persistent northeasterly flow brings in plenty of cool 
moist air in off the ocean and precipitable waters  are 125 to 175 percent of 
normal for early October. This will allow for a much needed steady 
rainfall across most of the area with roughly half an inch to an 
inch of rain expected in most locations. Higher amounts are 
possible where bands of heavier rain set up. While we can/T 
determine exactly where these bands will develop...the best chance 
for higher rainfall amounts looks to be across southeast mass 
where rain will last the longest before the low pulls away to the 
east. 


Used locally produced bias corrected MOS for temperatures today 
which will remain cool around 60 degrees for most locations. 


&& 


Short term /6 PM this evening through 6 PM Thursday/... 
tonight...steady rain will come to an end slowly from west to east 
as low pressure pulls farther away from the region. Rain is likely 
to continue across eastern Massachusetts and Rhode Island through much of the night. 
Continued easterly flow will keep low level moisture in place 
allowing for low clouds...drizzle...and fog to remain across the 
region. Low temperatures should be in the 50s. 


Thursday...will start to see some drying...particularly in the west 
as high pressure starts to build in. Cape and islands will be last 
to lose the moisture but clouds should begin breaking up by the end 
of the day. Below normal temperatures remain with highs around 
60...except for the Connecticut valley where they may climb into the 
middle 60s. 


&& 


Long term /Thursday night through Tuesday/... 
big picture... Alaska shortwave digs over the western USA/Canada and 
kicks the established upper trough east to the Great Lakes. This 
brings a broad cyclonic flow over the eastern USA with below 
normal heights while an upper ridge builds over the western USA. 


Embedded in this flow...a closed low over New England moves off 
through the Maritimes Thursday and Friday. 


The dailies... 


Thursday night-Friday... high pressure builds south over New 
England. Cross sections of relative humidity show drying in most layers Thursday 
night but then an increasing layer of moisture below 800 mb by 
Friday afternoon. This suggests clearing...but followed by 
increasing low clouds again during Friday. Relative humidity charts from the GFS 
and European model (ecmwf) show cloud moisture being pushed west across the Gulf of 
Maine from the departing coastal low...and into southeast New Hampshire/eastern 
mass Friday afternoon. By Friday night the same models show light 
precipitation over this area...suggesting sprinkles or drizzle. 


We will have a dry forecast during Thursday night and Friday...but 
with increasing clouds from the east Friday night along with 
fog/drizzle and in east coastal areas a chance for measureable precipitation. 


Light east winds will limit mixing...and temperatures in this shallow layer 
will support maximum temperatures in the 60s...coolest near the east mass coast 
and warmest in the CT valley. 


Saturday... the upper trough moving across the Great Lakes deepens 
as it moves it. The trough uses a 110 knot jet to push a cold front 
east toward New England. Temperature profiles show a strong thermal 
gradiant across the front. The deepening of the trough also turns 
the upper flow over New England more from the south-southwest 
drawing moisture north...precipitable water values are forecast to 
reach 1.5 to 1.6 inches. Stability parameters are less than 
marginal...middle level lapse rates are 5c/km or less and totals are 
less than 44. 


Forecast will continue to feature likely probability of precipitation but slightly slower 
than previously. This slower timing aligns with similar trends in 
the GFS and European model (ecmwf) with windshift in the CT valley 2 PM to 8 PM and 
in the coastal plain 8 PM to midnight. 


Sunday-Monday-Tuesday...shortwave moves north of our area 
Sunday...but the main trough axis remains over the Great Lakes. 
Contour heights at 500 mb are below normal over the weekend but then 
moderate to near normal during the first part of next week. Sunday 
and Monday look dry with seasonably cool temperatures. The trough axis 
ejects northeast by Tuesday and may support a chance of showers at 
that time. 


&& 


Aviation /12z Wednesday through Sunday/... 
forecaster confidence levels... 


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


Short term...today through Thursday...moderate confidence. 


Today...IFR ceilings/visibilities in the east and MVFR in the CT valley and 
parts of southern New Hampshire. This may slowly improve to a more widespread 
MVFR at best...but should then lower to IFR again with sunset. 


Tonight...IFR/LIFR conditions the first part of the night. This 
may show some slow improvement from west to east later in the 
night with the most improvement towards daybreak Thursday. 


Thursday...areas of IFR /mainly in the east/ will improve to VFR. 


Kbos...high confidence in trends...lower confidence in timing. 


Kbdl...high confidence in trends...lower confidence in timing. 


Outlook...Thursday night through Sunday...moderate confidence. 


Thursday night-Friday...VFR. Areas of IFR ceilings/visibilities in patchy fog 
early Friday morning. Areas of IFR ceilings move west off the ocean 
into east coastal Massachusetts including the cape and islands late 
Friday and more likely Friday night. 


Saturday...IFR ceilings from the Worcester Hills east during the 
morning. VFR farther west to start the day but lowering to MVFR and 
scattered IFR as a cold front approaches late in the day and brings 
showers. Wind shifts from south during the day to west behind the 
cold front late in the day and early at night. 


Sunday...VFR with gusty west winds. High pressure builds over the 
region with fair weather. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term...today through Thursday...high confidence 


Persistent northeasterly winds increase through the day gusting 
to around 25 kts by about midday today. Seas continue to 
increase...particularly on the northeastern waters and into Boston 
Harbor and Cape Cod Bay. Added all the waters except for 
Narragansett Bay to the Small Craft Advisory for both winds and 
seas and all small craft advisories have been extended through 
Thursday. 


Outlook...Thursday night through Sunday...moderate confidence. 


Thursday night-Friday...northeast winds gusting 20 to 25 knots will 
maintain 5 to 9 foot seas on the outer waters and exposed eastern 
waters such as Massachusetts Bay. Small Craft Advisory will be 
needed. Fog and low clouds moving in from the Gulf of Maine may 
create poor visibilities Friday night. 


Saturday... lingering poor visibilities Saturday morning in fog and low 
clouds. These conditions will improve later in the day as a cold 
front approaches with showers. South winds will gust 25 to 30 knots 
during the day and evening...shifting to west after the cold front 
moves through Saturday night. Seas will continue at 5 to 8 feet on 
the outer waters and other exposed waters. Small Craft Advisory is 
likely. 


Sunday...winds and seas diminish a little but still rough. Seas will 
linger at 5 to 7 feet on the outer waters. West to southwest winds 
will gust to 25 knots.
