NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
147 PM EDT Monday Oct 20 2014 


Synopsis... 


High pressure will slide to the south of the region today keeping 
the weather quiet. A long duration coastal storm will bring 
periods of rain Tuesday through Thursday with lingering showers 
Friday as the storm slowly pulls away from New England. Dry and 
mild weather is expected next weekend. 


&& 


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


145 PM update... 


Mostly sunny skies at middle afternoon will gradually give way to more 
middle level cloudiness that will work in from the west 
through early evening. High temperatures will top out in the middle to 
upper 50s in most locations...but less wind than yesterday will make 
it feel much milder over the next few hours. 


&& 


Short term /6 PM this evening through 6 PM Tuesday/... 


Tonight and tomorrow... 


Low pressure system will begin to develop across the Great Lakes 
overnight. This puts the region in more of a southwest flow and 
begin to moisten the column. Anticipate clouds to be on the increase 
overnight limiting the potential for radiational cooling. Therefore 
kept temperatures in the low to middle 40s...warmer along the South Coast 
thanks to the SW flow. 


SW low level jet will begin to increase closer to daybreak and within the SW 
warm air advection flow...showers will develop in the morning hours. The best shot 
will be across the cape and islands and perhaps the coastal 
plain...align with the location of the low level jet. There is a slight chance 
for some thunder over the southeastern waters and even the cape and 
islands on Tuesday with cape values near 500 j/kg combined with 
steep lapse rates and Li values below 0. Because of this and the 
increasing low level jet have inserted isolated thunder into the forecast. 


Upper level low will become cutoff over the eastern Great Lakes 
during the day...and will dominate the region for the remainder of 
the week. Although the main shortwave/lift will be away from the 
region...there is still the potential for a few showers to develop 
across the western zones. Right now have the higher confidence that 
the cape and the islands will see the best chance for rainfall on 
Tuesday. 


Because of the return flow and that southern New England is in warm 
air advection side of the system...temperatures will warm into the upper 
50s to middle 60s. 


&& 


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


* periods of rain of varying intensity expected through Thursday as a 
coastal storm stalls south of new eng 
* lingering showers Friday but slowly improving conditions 
* mainly dry and mild weather next weekend 


Overview... 
guidance in excellent agreement on evolution of the coastal storm 
that develops off the middle Atlantic coast Tuesday night before finally 
pulling away from new eng Friday/Friday night. Tight clustering among the 
models on the track of the storm which stalls S of new eng for a 
time as it gets captured under the middle level circulation. Despite 
the good agreement on the mass fields there are differences in the 
timing and placement of quantitative precipitation forecast during the period. So while confidence 
is high that periods of rain will affect the region through at least 
Thursday...there is still uncertainty on where/when heaviest rain will 
fall. Strong winds and coastal flooding will not likely be 
significant factor in southern New England as core of low level jet expected to 
remain to the north. Used a blend of available guidance for 
probability of precipitation/quantitative precipitation forecast to account for model variation in these fields. 


Dailies... 


Tuesday night through Thursday... 
while we expect periods of rain to affect southern New England during this 
time...confidence is below average on exact timing and location of 
heavier rainfall. Models are signaling a possible dry slot moving 
up from the south Tuesday night into early Wednesday which may result in 
lighter precipitation during this time. Heaviest rain may be during Wednesday 
night Thursday as middle level low lifts north into region with increasing qg 
forcing and potential for more convection associated with cooling temperatures 
aloft. Using a blend of available guidance yields rainfall of 1-3 
inches with highest amounts across NE Massachusetts into S New Hampshire. Winds do not 
appear to be a significant factor for southern New England as core of low level jet 
will remain to the north. A period of gusty NE winds could affect 
coastal NE Massachusetts late Tuesday night/Wednesday but confidence is low. 


With strongest winds likely north of the region...the threat for coastal 
flooding remains low as seas and storm surge will not likely be high 
enough to cause problems. However...the risk continues for coastal 
beach erosion with wave action over several high tide cycles. 


Friday... 
coastal storm will be east of Cape Cod by Friday morning and slowly 
lifting north toward Nova Scotia during the day. While conditions 
should be improving...scattered showers will likely continue under 
lingering cold pool aloft with middle level low just east of the region. 


Sat and sun... 
looks mainly dry next weekend. Cold frontal passage sometime late 
Sat/Sat night could bring a few showers. Sat will likely be the 
mildest day of the weekend with maxes well into the 60s...then 
cooler sun behind the cold front. 


&& 


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


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


Short term /through Tuesday night/... 


This afternoon...high confidence in VFR. 


Tonight...high confidence in VFR. Scattered showers may develop 
across eastern New England toward daybreak. 


Tuesday...moderate confidence. Conditions probably deteriorate to 
mainly MVFR thresholds...but brief IFR ceilings/visibilities are possible. 
Scattered showers expected with an isolated thunderstorm or two 
possible. Bulk of the focus across eastern New England. 


Tuesday night...moderate confidence. Low end MVFR to perhaps IFR 
conditions dominate in low clouds...scattered showers and fog 
patches. The bulk of the activity will likely be found across our 
northern zones. 


Kbos...high confidence in taf tonight with moderate confidence on 
Tuesday. Low probability of an isolated thunderstorm on Tuesday. 


Kbdl...high confidence in taf tonight with moderate confidence on 
Tuesday. 


Outlook...Wednesday through Friday... 


Wednesday through Thursday...high confidence overall with areas 
of MVFR/IFR and periods of rain of varying intensity...but low 
confidence on details. Low probability of NE wind gusts to 25 knots across NE 
Massachusetts coast late Tuesday night/Wed. 


Friday...moderate confidence. A mix of MVFR/VFR with scattered showers. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /today through Tuesday/...high confidence. 


Today... 
high pressure builds over the waters allowing for the winds to 
slowly diminish. Westerly winds will switch to the southwest by 
the afternoon. Seas will lingering around 5 feet during the 
the afternoon so have expanded Small Craft Advisory accordingly. Would not be 
surprised if it is cancelled earlier. 


Tonight... high pressure moves offshore. Southwest winds will remain 
below 25 kts and seas will remain below 5 feet. Light rain moves 
up from the middle Atlantic coast late at night. 


Tomorrow...southwest flow will allowing rain showers to move 
across the southeastern waters. Conditions will remain below Small Craft Advisory 
but there is a low probability for an isolated thunderstorm during the day. 


Outlook...Tuesday through Friday... 


Tuesday night and Wednesday...winds generally below Small Craft Advisory...but a period of NE 
wind gusts to 25-30 knots possible over NE Massachusetts coastal waters although 
confidence is low. Low probability winds could reach gale force over waters 
east of Cape Ann. Highest seas 6-9 feet late Tuesday night/Wednesday over NE Massachusetts 
coastal waters. 


Wednesday night and Thursday...moderate confidence. Easterly winds mainly 
below Small Craft Advisory with low probability of Small Craft Advisory NE gusts over NE Massachusetts coastal waters. 
Highest seas 6-8 feet remain over NE Massachusetts coastal waters. 


Friday...mainly northwest wind gusts to 20 knots with low probability reaching 25 knots. 
Small Craft Advisory seas over eastern Massachusetts coastal waters. 


&& 


Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
New Hampshire...none. 
Rhode Island...none. 
Marine...Small Craft Advisory until 2 PM EDT this afternoon for anz250- 
254.
