Synopsis
Blustery and cold conditions will prevail tonight into Monday.

Winds shift to southwest with milder temperatures Tuesday,
followed by a cold front sweeping across the region that will
bring showers late Tuesday night and Wednesday morning. Dry and
colder conditions expected late Wednesday through the end of the
week. Much colder weather spills into the region this weekend.

Near term until 6 am Monday morning
10 pm update...

lake effect snow machine is on with a fairly impressive band
down the mohawk valley into the albany, ny area and not spilling
into the southern berkshires and litchfield hills of northwest
ct. New 00z NAM simulating this band very well so will follow
this guidance closely, which has the band holding together and
moving across ct, possibly into western-central ma and maybe
surviving into ri overnight. Not expecting much if any
accumulation but vsby may briefly lower along with a quick
dusting or coating, while neighboring towns don t receive any
snow. Just the nature of these narrow mesoscale bands.

Therefore the only change to the forecast was to focus
pops QPF light snow amounts overnight will be across
ct western-central ma and into ri. Remainder of the forecast is
on track. Earlier discussion below.

Previous discussion...

secondary mid level trough and shortwave moves into new eng
tonight with cooling temps aloft. 500 mb temps down to -35c by
12z mon. This combined with some moistening of the column in
the low and mid levels may result in a few flurries or snow
showers, mainly western ma and northern ct where some lake
effect moisture may spill into the region. Hi-res guidance just
showing some spotty light QPF so continued slight chc pops in
the west.

While peak of the wind will be diminishing tonight, it will
remain blustery with gusts 25-30 mph at times as cold advection
continues. Lows mid 20s to lower 30s but the wind will make it
feel considerably colder.

Short term 6 am Monday morning through Monday night
Monday...

mid level trough exits the region with high pres building south
of new eng. It will be a dry day, but area of low and mid level
moisture moving through will result in sct-bkn CU developing.

850 mb temps starting out -10 to -12c with some moderation in
the afternoon. Chilly day with highs ranging from mid 30s
interior high terrain to lower 40s coastal plain. Strong
pressure gradient remains in place so it will be another windy
day. Soundings are well mixed in the lower levels and suggest
potential for gusts 30-40 mph at times, especially through 18z.

Strongest gusts expected over interior northern ma.

Monday night...

high pres moves off mid atlc coast with area of mid level
moisture lifting to the north so expect mostly clear skies.

Winds will be diminishing and backing to the SW and there will
still be enough gradient so not as cold as it otherwise would
be if winds were calm. Generally followed a blend of mos
guidance for min temps. Temps will likely slowly rise
overnight along the south coast and CAPE islands.

Long term Tuesday through Sunday
Highlights...

* warm but windy for Tuesday
* cold frontal passage on Wednesday will drop temps through the
day with showers.

* dry but chilly for thanksgiving day
pattern overview confidence...

building high pressure over baja california will push the ridge into
the western CONUS for next week. This in combination of the blocking
high over northeastern canada and greenland will favor east coast
troughing through the period. 12z models and their ensembles are in
good agreement on the large scale pattern. However, some differences
will remain on timing and amplitude of each wave. Overall trend in
the forecast for southern new england will be wet weather for
Wednesday with drying trend into the end of the week. Will have to
continue to watch the weekend as with offshore low to the east and
approaching system from the west and how those two systems will
impact each other. Otherwise temperatures will trend below average
for the week.

Details...

Tuesday into Wednesday... High confidence.

Mid-level ridge will build over the region on Tuesday as winds
switch to the SW and WAA returns. Temperatures will warm within this
southwesterly wind as 50's return back to the region. A few sites
may be near 60f depending on how much mixing occurs. Approaching
cold front from the west will result in a developing LLJ with 925mb
winds reaching 40-45 kts. Once again another windy day on Tuesday.

Cold front from the great lakes will pass through the region on
Wednesday. A coastal low off the coast of the carolinas appears to
ride along or out ahead of the front. Latest guidance continues to
trend this low closer to the region, thus allowing for more moisture
in the mid-levels. The GFS appears to be on the slow end of the
developing low, thus not capturing enough moisture when the front
moves through. Therefore trended with the ec ukmet NAM for this
portion of the forecast. Precip will begin to overspread the region
overnight and result in widespread rainfall Wed morning. Highest
confidence is south and east of i-95, closer to the mid-level
moisture. Regardless appears that most of the region will see some
rainfall, which highest amounts closer to SE ma.

One thing we will have to watch on Wednesday is the available
moisture and timing of the caa. Some guidance indicates that a few
flakes can fly on the backside of the front. Uncertain on if there
will be moisture. Regardless, trend is only trace to less than if it
does accumulate on the roads.

Thanksgiving into Friday... High confidence.

Behind the front on Wednesday, CAA will move back into the region
for Thursday. High pressure will move south of the region resulting
in a chilly but dry day for thanksgiving.

Passing shortwave to the north Friday morning may bring in some
clouds, but another dry but more seasonable day.

The weekend... Low confidence.

High pressure and mid-level ridge Friday night will lead to a
warming trend on Saturday. Winds will back to the southwest as
another front from the west approaches. Behind this system
anomolous cold air will spill into the region putting temps well
below average. While a few waves will move through this period,
overall precip looks light.

Aviation 03z Monday through Friday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Monday night ... High confidence.

03z update...

only change will be to insert vcsh (snow showers) at bdl baf and
possibly orh overnight as lake effect snow bands from ny state
spill into ct, western-central ma and possibly into ri.

Otherwise previous tafs remain on track. Earlier discussion
below.

=====================================================================

effect snow showers may spill into western ma and northern ct
tonight. W NW winds diminishing but remaining gusty with 25-30
