NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Taunton Massachusetts 
139 am EDT Thursday Apr 2 2015 


Synopsis... 
high pressure and chilly overnight. Turning milder into Thursday 
with breezy southwest winds. Rain chances increase towards Friday 
morning with the threat of heavy rain and thunderstorms as waves 
of low pressure slide across a slow moving cold front. Dry and 
chillier weather follows by late Saturday into Saturday night. 
Fast moving low pressure may bring a few rain and/or snow showers 
to the region Sunday into Sunday night. Periods of unsettled 
weather possible for the first half of next week...but confidence 
is quite low. 


&& 


Near term /until 6 am this morning/... 
1o PM update... 
forecast remains on track for the most part. Most adjustments were 
to temperatures to bring them up to current trends and expected 
radiational cooling values. Also...models not handling dewpoints well 
at all...so manual adustments were performed there. 


Details... 


Winds taper as high pressure pushes into the region. Anticipate 
quiet weather consisting of mostly clear conditions and light / 
variable winds. While some increasing clouds late...expecting an 
opportunity for radiational cooling. A consensus blend of MOS 
guidance...nudged temperatures down a few degrees for areas which 
notoriously radiate out and valley locations subject to cold-air 
drainage /katabatic flow/. 


&& 


Short term /6 am this morning through 6 PM Friday/... 
*/ Thursday... 


Warm front lifting NE across the region along the nose of return 
warm-moist SW-flow along the west-periphery of the low- to middle-level 
ridge axis pushing east. With middle- to upper-level support lacking... 
feel a dry forecast prevails. Though there is some hint of low- 
topped showery weather the better chances of which are along the west- 
slopes of higher terrain...synoptic forcing and dynamics are largely 
absent...mainly found northwest across Canada. 


Onshore flow increasing out of the S in response to an enhancing 
pressure-gradient with the approaching low and high pressure pushing 
offshore. Increasing SW-flow aloft beneath an anticipated boundary- 
layer inversion at 850 mb temperatures warm to +6-8c with h925 +2-4c. 
But with clouds remaining a nuisance mainly over the north/west of New 
England...whereas S/east remain mostly clear...the high-angle of the 
early April sun will likely allow for highs up around the low- to 
mid-50s. The warm-spots likely in the lower CT-valley...Merrimack 
River valley...and interior east/southeast Massachusetts. Cooler along the S-shore and 
out on Cape Cod with the onshore SW-flow off the much cooler waters. 


*/ Thursday night... 


Frontal boundary sweeps S across New England towards Friday morning. 
Nearly parallel flow along the boundary. Attendant synoptic forcing 
and dynamics lacking. There is little indication of convergence nor 
deep-layer ascent. Though anomalous precipitable waters  on the order of +1-2 South Dakota as 
consensus forecast guidance suggests 1.00-1.25 inches...without much 
forcing / lift...can not efficiently get the atmosphere to rain 
out. 


So while wet weather is likely...expect just showers. No thunder and 
nothing pronounced. Scattered activity. No flooding concerns. Just 
an abundance of clouds and overall a mild night the likes we have 
not seen since Thanksgiving 2014 for Boston / Providence...since 
late October for Hartford / Worcester...using 45 degrees as the 
threshold. Amazing! Looking at lows around the low- to mid-40s. 


Will need to monitor closely for the presence of dense fog. Higher 
dewpoint air over the colder ocean...and relatively colder ground 
with lingering snowpack...will likely result in the development of 
some dense fog. Though milder conditions ushered by breezy light snow shower 
flow. Will this deter fog development remains to be seen. Of some 
certainty will be the expectation of breezy high dewpoint air 
along with wet-weather will allow for faster erosion of any left- 
over snow. Perhaps we can finally say goodbye to the remnants of 
winter. Right now we have a fog-free forecast as neither climatology nor 
MOS-guidance suggests fog mostly due to anticipated breezy winds. 
Again...will just have to monitor. 


SW-gusts 25-35 miles per hour across S/southeast coastal New England...with 15-25 
miles per hour gusts across the interior. 


&& 


Long term /Friday night through Wednesday/... 
* quite unsettled weather expected through the long term 
* highest confidence in periods of showers Friday into Sat am 
* rain/snow showers possible again sun 
* low confidence on unsettled weather pattern next week 


Models are not in very good agreement at all for much of the 
forecast period. The European model (ecmwf) in particular seems to be somewhat of 
an outlier. However...confidence is rather low through the period 
but especially next week. Somewhat higher confidence in the 
forecast through Sunday...though there are still some model 
differences that could yield different forecast results. 


Friday through early Saturday...a shortwave trough and its attendant 
low pressure system will move over the northeastern United States... 
bringing widespread showers to the area. The 01/12z GFS/NAM bring 
this low pressure system up from the lower MS valley are through 
southern New England. The 01/00z European model (ecmwf) brings the low pressure up 
through northern New England. This would mean a difference in 
temperature profiles as well as wind directions during the day. 
However...Don/T believe there is a significant enough difference 
to result in a change of ptype from rain. Leaning more towards the 
GFS/NAM solution. 


Warmest day of the week should be Friday when temperatures will actually 
reach or possibly even climb above normal. This may result in a 
few locations reaching 60+ degrees for the first time this Spring. 


Rest of Saturday...temperatures fall back below normal behind the 
cold front that trails this low pressure system. Much of the day 
should be dry prior to another front approaching the area. 


Sunday...a quick cold front will move through the region bringing 
another round of rain and possibly snow showers to the region. 


Monday through Wednesday...a very unsettled pattern with low 
confidence in the details and timing of the forecast. There is 
potential for rain showers each day in one model or another but not 
expecting a washout any one day nor through the entire period. 
Temperatures will be fighting between cooler air to the north and 
warmer air to the south. Given the pattern as of late...expect 
the cooler air will likely win out. Will go with a blend of model 
guidance for this time period. 


&& 


Aviation /05z Thursday through Monday/... 
forecaster confidence levels... 


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


Short term /through Friday/... 


Through today...high confidence. 
VFR. SW winds pick up this afternoon with gusts 25-30 knots possible 
at times. 


Tonight into tomorrow...moderate confidence. 
Periods of rain showers overnight shift from northwest to southeast...then stall 
along the S coast into the day on Friday. Periods of MVFR/IFR not 
out of the question...but it may take much of the overnight for 
ceilings or visibilities to drop below VFR. Conditions improve to VFR across 
the north on Friday with northwest winds. 


Kbos taf...moderate confidence. Main issue is timing of any 
showers late tonight. 


Kbdl taf...moderate confidence. Main issue is timing of any 
showers late tonight. 


Outlook...Friday night through Monday... 


Friday night through Saturday morning...moderate confidence. MVFR 
conditions are likely in rain showers. IFR conditions are possible 
Friday night in fog. 


Saturday afternoon and night...moderate confidence. Mainly VFR. 


Sunday and Monday...low confidence. Mainly VFR. Periods of 
MVFR/IFR in rain/snow showers. 


&& 


Marine... 
forecaster confidence levels... 


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


Short term /through Thursday night/... 


Tonight...high confidence. 


High pressure building across the waters. Winds becoming light and 
variable. Seas relax. 


Thursday...high confidence. 


Winds increasing out of the SW through the day with gusts up to 
25 kts along the S-shore by evening. Swell building resulting in 
seas in excess of 5-feet beginning by afternoon into evening. 


Thursday night...moderate confidence. 


Continued blustery SW-flow with gusts 25-30 knots over S/southeast waters. 
Low confidence at this time...but dense IFR fog possible. Winds 
may limit fog development. Will need to closely monitor. Low 
confidence concerning gales but could not rule out an intermittent 
gale-force gust at times. Seas building 6-8 feet on the outer 
waters...including Rhode Island / bi sound. Showery weather...not thinking 
any heavy rain / thunderstorms at this time. 


Outlook...Friday through Monday... 


Friday through Saturday...seas increase as low pressure approaches 
and then moves over the waters. Southwesterly winds 15 to 20 kts 
shift to the northwest Saturday morning. Gusts up to 30 kts are 
possible at times. Small craft advisories are likely for both 
winds and seas on all the waters with a low probability of gales 
being necessary for the outer waters for a period Saturday. 


Saturday night through Sunday...seas diminish...but remain above 5 
feet on the outer waters. Northwesterly winds diminish but remain 
above 25 kts for most of the waters. Small craft advisories will 
likely be necessary. 


Monday...seas fall below 5 feet as a brief period of high pressure 
builds over the waters. Southwesterly winds continue to diminish 
and slowly shift to the southeast.

Box watches/warnings/advisories... 
CT...none. 
Massachusetts...none. 
Rhode Island...none. 
Marine...Small Craft Advisory from 2 PM this afternoon to 6 am EDT
