NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
454 am EDT Sat Oct 25 2014 


Synopsis... 


A weak ridge of high pressure moves across the region 
today providing sunshine and mild weather. A cold front will sweep 
across the area tonight and may be accompanied by a few showers. 
Dry...cool and blustery weather follows Sunday into Monday...before 
temperatures moderate Tuesday and especially by Wednesday. A cold 
front may bring a brief period of scattered showers Wednesday 
afternoon and evening followed by much cooler temperatures Thursday 
into Friday. 


&& 


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


*** sunshine and mild temperatures return today *** 


Today... 


Weak short wave ridging and associated subsidence moves across the 
area today providing partly to mostly sunny skies along with 
temperatures about 5 degrees warmer than normal. Model soundings 
suggest blyr mixing extends up to about 925 mb. Temperatures at this level 
are around +10c. This supports highs in the low to middle 
60s...slightly cooler higher terrain. However it will feel even 
milder given light winds today. West winds 5 to 15 miles per hour will support 
warm readings along the coast including Cape Cod and the islands. 
Temperatures may fall back a few degrees here later in the day as winds back 
to the southwest off the ocean. 


&& 


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


Tonight... 


Impressive northern stream short wave plunging southeastward across 
Lake Superior early this morning. Very strong jet dynamics with this 
feature however best synoptic scale forcing and deep layer moisture 
tracks across northern New York and northern New England tonight. 
Therefore the cold front associated with this short wave will likely 
only yield a few showers from 00z/8pm to 06z/2am across northern Massachusetts 
and southwest New Hampshire. Otherwise the remainder of southern New England 
should remain dry. Behind the frontal passage /06z/ west-northwest winds 
increase in response to increasing cold air advection. 


Sunday... 


About 10 degrees or so colder than Sat along with a brisk northwest 
wind behind the departing cold front. Potent trailing short wave 
trough comes through the region in the afternoon. In response to modest 
cold air advection 925mb-700mb lapse rates increase to 7c/km. This 
combined with synoptic scale lift from the approaching short wave 
should yield a few afternoon showers. Deep layer moisture is lacking 
and this should limit areal coverage to isolated or widely 
scattered. Cooler temperatures aloft will combine with cloud cover to yield 
highs only in the 50s. In addition gusty northwest winds will make it feel 
even cooler. 




&& 


Long term /Sunday night through Friday/... 


Highlights... 


* dry and cool Monday 
* remaining dry but milder on Tuesday 
* unseasonably mild Wednesday with some 70 degree readings possible 
* period of scattered showers possible Wednesday afternoon and/or evening 
* turning much cooler by next Thursday and Friday 


Details... 


Sunday night... 


West to northwest winds behind the cold front will continue to usher 
cooler air into the region. Winds will not decouple and 
it will remain gusty across portions of the coastal plain. Low 
temperatures will fall between 40 and 45 in most locations by daybreak 
Monday...but enough wind will keep low temperatures from really bottoming 
out. 


Monday... 


Partly to mostly sunny skies and cool temperatures continue on Monday with 
northwest flow aloft and at the surface. High temperatures should reach 
into middle to upper 50s...but it will be breezy. BUFKIT soundings 
continue to show good mixing that will support northwest wind gusts 
of 20 to 30 miles per hour. 


Monday night... 


A ridge of high pressure builds in from the west resulting in 
decoupling winds and a good night of radiational cooling. Low temperatures 
to fall well down into the 30s across the outlying locations...to 
the lower to middle 40s in the urban centers. 


Tuesday... 


The high pressure system moves off the coast early Tuesday allowing a 
return southwest flow of air to work into the region. We should see 
at least partial sunshine allowing high temperatures to reach into the 
lower to middle 60s...but it should remain dry. 


Wednesday... 


Southwest flow ahead a cold front will allow for an unseasonably mild 
day. Guidance numbers are likely too cool based on pattern 
recognition and support from European model (ecmwf)/ggem 2 meter temperatures. 850 
mb temperatures near 10c and good mixing should support highs in the upper 
60s to lower 70s across most of the region. The cold front will 
probably trigger a brief band of scattered showers Wednesday afternoon 
and/or evening. Moisture will be limited...so expect any rain to be 
of a short duration in a given location with light amounts. 


Thursday and Friday... 


High pressure will build into the region behind the front bringing 
mainly dry weather Thursday into Friday but much cooler temperatures. High 
temperatures should generally be in the 50s. A secondary front will 
probably move through the region late Friday...bringing the coldest 
weather so far this season to start the next weekend. Will have to 
watch if a wave of low pressure forms along the front late Friday or 
Friday night...but confidence is low. 


&& 


Aviation /08z Saturday through Wednesday/... 
forecaster confidence levels... 


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


Short term /through Saturday night/...high confidence. 


2 am update... 


Today...back edge of MVFR ceilings across central-eastern Massachusetts and Rhode Island 
at 06z/2am...and continuing to move east. These MVFR ceilings should 
exit the cape around 14z-15z. Thereafter VFR prevails with light 
to modest west wind becoming SW toward 21z-00z. 


Tonight...VFR to start but then quickly a brief period of marginal 
MVFR/VFR ceilings move across the area associated with a cold front. 
Low risk of a few showers across northern Massachusetts into southwest New Hampshire 
00z-06z. May see a few gusts up to 20 knots toward daybreak. 


Sunday...cold front moves offshore in the morning but lots of Post 
frontal clouds in the bkn035-045 category. Low risk of a few light 
showers in the afternoon. West winds will gusts 20-25 knots in the 
afternoon. 


Kbos...high confidence in taf through 00z...then slightly lower 
confidence on timing of MVFR/VFR ceilings. 


Kbdl...high confidence in taf through 00z...then slightly lower 
confidence on timing of MVFR/VFR ceilings. 


Outlook...Sunday night through Wednesday 


High confidence. Mainly VFR other than a brief period of MVFR 
conditions Wednesday afternoon/evening in a band of scattered rain showers. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Sunday/... 


Forecast confidence is high through Sunday. 


Today... 


Modest northwest winds this morning become westerly around midday and then 
SW toward sunset. Dry weather and good visibility today. NE swells 
continue to subside across the eastern Massachusetts waters. 


Tonight... 


Cold front sweeps across the waters 03z-06z with west-northwest winds 
increasing to 20-30 knots. A few light rain showers possible northern 
Massachusetts waters. 


Sunday... 


West-northwest winds remain strong at 20-30kt. Low risk of a few light rain 
showers in the afternoon. Otherwise good visibility. 


Outlook...Sunday night through Wednesday... 


Sunday night and Monday...high confidence. West to northwest winds 
behind a cold front will gust to between 25 and 30 knots in the cool 
air advection pattern. There is even a low probability of brief 
near 35 knot wind gusts across the eastern outer-waters. 
Regardless...Small Craft Advisory headlines will be needed for all waters Sun night 
into Monday. 


Monday night and Tuesday...moderate to high confidence. Winds/seas 
diminish below Small Craft Advisory thresholds as high pressure builds in from the 
west. 


Tuesday night and Wednesday...moderate confidence. High pressure 
moves off the coast allowing for a return of southwest winds across 
the waters. Marginal southwest Small Craft Advisory wind gusts may develop by Wednesday 
afternoon across the southern waters.
