Synopsis
Low pressure will track southeast of the region on Wednesday,
bringing a period of mostly rain to the area. Some snow will be
found in the mountains. This low will pull a cold front across
the area Wednesday night. Thanksgiving will mainly sunny but
chilly, with a warming trend Friday into Saturday. Another cold
front crosses the area on Sunday and could bring some rain or
snow showers, with another blast of cold air expected early next
week.

Near term tonight
Southwesterly flow continues tonight as an upper trough and
associated cold front move east toward the region. Expect
increasing clouds overnight and temperatures generally only
falling into the 30s.

Short term Wednesday and Wednesday night
Two waves are headed in our general direction within the
southwest flow between the atlantic ridge and the canadian
trough. The first is a southern stream wave riding around the
periphery of the atlantic ridge. Moisture has built up over the
southeastern united states pulling from the caribbean and gulf
of mexico. This moisture will spread northward along the east
coast tonight and arrive in northern new england just in time
for the cold front to arrive Wednesday morning. With more
moisture available, it is becoming increasingly likely that some
precipitation will fall along the northern new england coastline
ahead of the front.

The second wave is the deeper one, featuring a large scale
trough over ontario and the upper great lakes. This will move
east northeast and arrive in new england on Wednesday, dragging
a cold front along with it. This second wave is expected to
capture and merge with the first southern stream wave with the
two linking up near nova scotia, too far east for us to see a
heavy precipitation event here. However, there will be enough
moisture streaming northward ahead of the southern wave that we
should see rain and mountain snow break out particularly as the
cold front drops out of the mountains midday Wednesday. Ahead of
the front there will be enough warm moist air to keep things as
rain, but behind it especially in the mountains this could fall
as snow. Not looking at a lot in terms of total precipitation,
with generally 0.1 to 0.5 inches of rain expected. It may also
be a fairly short duration rainfall as the eastward progression
of the cold front will pull in cold, dry air out of canada and
work to shut off precipitation.

With the cold front moving through during the day Wednesday, it
should be a colder night Wednesday night. Low level wind flow
remains light to moderate deep into the night, but we should
still see temperatures fall into the 20s to perhaps a few teens
as the core of the cold air arrives.

Long term Thursday through Tuesday
Fairly persistent 500mb blocking downstream of new england,
with ridge taking residence over greenland, and pushing N to the
pole, along with ridging over the WRN conus, will effectively
push the coldest air over the hemisphere toward siberia. It will
also continue to help promote a faster flow, that will trend
toward broad cyclonic, but still feature some fast-moving waves
and frequent temp changes into early next week.

Overall, thanksgiving day looks mainly sunny with light winds but
chilly with highs only in the 30s, probably closer to 30 in the
colder mountain spots, and maybe reaching 40 in the more
urbanized areas of SRN nh. Thursday night will see a 500 mb
wave pass to our north, and bring some clouds in overnight and
maybe a few shsn in the mountains. Should see skies clear
somewhat Fri morning, with temps a few degrees warmer than
Thursday, mainly in the mid 30s to mid 40s. 500 bm ridging
builds in on Saturday in response to trough digging SE toward
the great lakes. This should allow a decent SW flow and help
push highs up into the mid 40s to low 50s, which is above
normal.

The next chc of precip will be Sat night into Sunday as 500 mb
trough continues to deepen as it moves into new england. 12z
euro phases the the system far enough east that it would have
limited effect on cwa, other than maybe a round of shra shsn
with passage of the cold front. Once again, it will turn sharply
colder behind the front with highs on Monday limited to the 30s
once again. The trend for next week beyond Monday looks to be
warmer and mainly dry conditions.

Aviation 18z Tuesday through Sunday
Short term...VFR today with southwest wind gusts dropping off
early this evening. Clouds increase through the night, with MVFR
conditions possibly by Wednesday morning. Rain is most likely
along the coast during the day Wednesday, with MVFR to ifr
conditions expected. A cold front moves in from the northwest
during the day, with some snow showers north of the mountains
and MVFR conditions there. The cold front is a dry front so it
should clear things out as it moves through leading toVFR
conditions by Wednesday evening.

Long term... MainlyVFR Thu through Sunday. Possible shrasn
possible Sunday which may briefly cause flight restrictions.

Marine
Short term... South to southwest winds continue to gust to 25 to
30 kt this afternoon, but should diminish a bit overnight. A
cold front moves through Wednesday with north winds gusting to
25 to 30 kt again. Thus there may only be a brief few hour
period where small craft advisory conditions are not observed.

Long term... May need SCA Sat into Sunday. Initially on Sat due
to SW flow ahead of a cold front, and then on Sunday into sun
night in NW flow behind the cold front.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 10 pm est this evening for anz151-
153.

Small craft advisory until 5 am est Wednesday for anz150-152-
154.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
