Synopsis
A weak ridge of high pressure will briefly build into the
region today before sliding offshore. A weak area of low
pressure will track across southern new england and the gulf of
maine tonight into the day Monday. This disturbance will produce
a light snowfall from southern new hampshire across the coastal
plain of maine late tonight into the day Monday. Another area
of low pressure will pass south of the region Tuesday. An arctic
front will cross the region Wednesday, followed by high
pressure building into the region through the end of the week.

Near term until 6 pm this evening
Update...

have updated the forecast based on current conditions. Latest
satellite imagery and surface observations already showing mid
and high cloudiness pouring into the region from the next
approaching system. Radar mosaics showing light snowfall from
this system in portions of new york state. As this precipitation
moves east, it will continue to encounter very dry air so most
areas will not receive any snowfall until later this evening
over southern new hampshire.

Minor adjustments made to current and forecast temperatures for
this afternoon by raising the MAX temperature forecast
slightly.

Prev disc...

554 am... Minor estf update to reflect the current
mesonet and satellite low cloud trends in near term grids.

Prev disc...

at 06z... A cold front extended from the gulf of
maine into southwest maine and southern new hampshire. A 1028
millibar ridge was over the eastern great lakes. The front will
press a bit further south this morning before stalling across
southern new england. The weak ridge will slide quickly east and
we'll see at least a few sunny periods before the ridge
retreats offshore by afternoon. By afternoon... The front and a
weak surface low begins to press back north and east accompanied
by increasing warm air advection cloudiness. It'll be another
below average day in the temperature department... With highs
ranging from the 20s across the mountains to the lower and mid
30s elsewhere.

Short term 6 pm this evening through 6 pm Monday
A shortwave impulse races eastward in broad cyclonic west-
southwest flow tonight and early Monday. The associated surface
low will track along the frontal boundary across southern new
england and into the gulf of maine during that time. Light warm
air advection precipitation develops overnight mainly south and
east of the mountains and foothills. The column is sufficiently
cold enough for snow and most locations in southern new
hampshire and along the maine coastal plain see a dusting to an
inch by dawn on Monday. The snow tapers quickly from southwest
to northeast during the day as the upper impulse and weak
surface low quickly exit into the maritimes. Additional
accumulations will range from a dusting to an inch... For total
accumulations ranging from a dusting to as much as two inches.

Long term Monday night through Saturday
The long term headlines feature another chance for light
accumulating snow on Tuesday, and then a very cold
thanksgiving.

On the hemispheric scale, the high amplitude blocking hold
through the week with strong rex block over europe allowing the
trough to deepen over ERN noam. There is a trend in the models,
especially the euro, for less amplified flow by next week with
a higher wave number, which will take the core of the cold air
off the pole and hudson bay and spread it more evenly among the
continents, which should allow for some warming over new
england.

Mon night will see a break in any action with some clearing as
cold front moves thu, and lows generally in the 20s. The front
stalls to our south on Tuesday, with another weak wave
developing along the front. Will be discounting the operation
gfs at this point, and going with something of a blend between
the 00z gefs ECMWF nam cmc, which bring another round of light
snow, and rain in SRN nh on tue. Models show diffuse jet dynamic
forcing and dry airmass, but the trough does get some 500 mb
energy and is riding along a mid lvl baroclinic zone, and
therefore forecast confidence is low, but highest QPF is in srn
nh and on the me coast. Highs Tue will range from the upper 20s
to low 30s in the N to the mid-upper 30s in the south.

Any precip will wind down late Tue and some clearing will occur
behind the system as winds shift to W and bring some colder air
in, with lows mostly in the teens, with lows 20s in SRN and the
me coast.

Wed will feature the passage of the arctic front, mainly from
nw-se during the afternoon. Highs should get into the 30s again
ahead of the front, bit will likely see temps fall behind the
front, mid-late afternoon in the north, and during the evening
in the south. Could see some shsn and even some squalls in the
mtns Wed afternoon, but this becomes less likely, but completely
out of the question toward the coast and in SRN nh, as air mass
ahead of this front will already be cold and dry. The question
will be how much moisture and warming will occur in SW flow
ahead of the front before the front moves through. We night will
see NW flow pick up a pick up behind the front and bring the
cold air in, with lows dropping to 5-10 in the N and 10-15 in
the south. Thanksgiving will be quite cold and windy (gusts of
25-30 mph at times and highs only in the 15-25 range, for the
most part. This will produce daytime wind chills of zero to 15
above from N to s.

The sfc low will continue to intensify over the maritimes, as
the sfc high pushes in from the west, which will help maintain a
pres gradient into Friday, which will keep the winds going,
though somewhat less than on thu. Thu night lows will range from
zero to +5 f in the mtns to 10-15 in the south, with wind
chills dropping to 5-10 below in the mountains and to near zero
in the south. Friday will be slightly warmer, as core of
coldest air will pass Thu night, but still highs still well
below normal, 20-25 in the mtns to around 30 in the south.

Sat looks dry and warmer, with mainly sunny skies.

Aviation 18z Sunday through Friday
Short term through Monday ...VFR. Conditions lowering to MVFR
btw 02z and 08z Monday in -sn with LCL ifr psb at southern nh
and coastal me terminals. Conditions improve toVFR btw 14 and
18z Monday from SW to NE as -sn ends.

Long term... Possible period of MVFR-ifr in sn ra on Tuesday, but
should see mainlyVFR wed-thu. Could see NW wind gusts approach
25 kt on thu.

Marine
Short term through Monday ... Winds and seas will continue to
drop off as weak ridge builds eastward today. A weak low will
cross the gulf of maine late tonight and Monday with vsby
restrictions in -ra -sn and fog. However... Winds and seas with
this disturbance are expected to remain below SCA threshold.

Long term... SCA likely will be needed Wed night into thu, with
a period of gales possible.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
