Synopsis
A trough of low pressure will linger over the region today and
high pressure will build in from the west tonight and Tuesday.

High pressure will shift east Tuesday night. Low pressure will
approach from the west on Wednesday... Shifting into southern
quebec by late in the day. A trailing cold front will push in
from the west Wednesday night and will stall just off the coast
by Thursday morning. Low pressure will track northeast along
this boundary Thursday and into the maritimes by Thursday
evening. A shallow ridge of high pressure will build in from the
west Thursday night followed by a cold front Friday.

Near term until 6 pm this evening
10 am... Several updates to the forecast, although nothing
significant. Dis tweak winds temps a bit through the day, but
very few places will get out of the single digits, and those
that do would only reach 10 or so. In the north, don't expect
to get above zero. Expecting to put up wind chill products for
tonight, but will wait for afternoon to package to determine
where the warning will be vs advisories, although warnings
likely in the far n, with advisories most everywhere else.

700 am update...

clouds have quickly filled in across the region early this
morning and expect this cloud cover to persist through the day
along with scattered snow showers later this afternoon. Have
also issued a coastal flood advisory for southwest maine and
coastal new hampshire for the time of high tide which occurs
around 1100 am. Lingering storm surge of around .5-.7 ft will
bring these locations to near flood stage later this morning
resulting in minor flooding and splash-over. Have adjusted area
temps tds which will show little change through the course of
the day. Otherwise no major changes to current forecast.

Prev disc... Cyclonic flow will persist over the region today
as deep upper low crosses the region. Any morning sunny breaks
will give way to cloudy skies and scattered snow showers. Best
chance of precipitation will be in the mountains where some
minor accumulations will be possible. Big story will be the wind
and cold as temperatures generally remain in the single numbers
for highs and strong northwest winds combine to produce bitter
wind chill values. Wind chill advisories remain in effect
through late afternoon for the mountains and foothills as well
as much of western and central new hampshire.

Short term 6 pm this evening through 6 pm Tuesday
Winds will subside somewhat tonight as high pressure builds in
from the west. Lingering clouds and scattered flurries during
the evening will give way to clearing skies and some very cold
overnight lows. Looking for lows of 10 to 20 below in the north
and zero to 10 below in the south. Bitter wind chills will
continue as northwest winds remain brisk and wind chill warnings
will likely be needed for the mountains overnight. Looking for
minimum values of wind chills of 30 to 35 below in the far
north and 20 to 30 below elsewhere.

High pressure will continue to build in from the west on
Tuesday... Cresting over the region by late in the day. Expect
sunny skies through early afternoon before high clouds begin to
spill into the region from the west. Return flow will help to
moderate temps somewhat producing highs in the teens north and
lower to mid 20s south.

Long term Tuesday night through Sunday
The good news for the extended is that temperatures will be much
warmer than they are now, with highs ranging from near 30 and
into upper 30s 40s Wednesday through Friday. Colder air rushes
in Friday night and will wedge over the higher terrain, keeping
the coldest temperatures across the north before moderating
Sunday. The somewhat bad news is that is looks like an active
winter weather pattern with at least a couple chances for snow
accumulation.

Tuesday night a long wave trough axis will push through the
eastern conus, with a surface frontal fracture approaching the
east coast by Wednesday morning. As this happens, additional
cyclone development will occur near virginia and precipitation
will spread into northern new england. It will be very cold
ahead of this system so expect the precipitation to be frozen or
freezing... Currently it looks cold enough for all snow at the
onset. As warmer air pushes north snow will change to rain
during the day Thursday for all but areas along the canadian
border. The very dry airmass ahead of this system should exit by
Tuesday night, with precipitable water values rising to 250% of
normal by Wednesday afternoon. Thus expect some areas of
moderate rain or snow. That said, this is not an especially
strong system and do not expect anything above 2-4" for the most
part.

Wrap around snow lingers Friday with a brief break ahead of the
next long wave trough axis pivoting through the plains and
ultimately reaching the northeast. Another reinforcing shot of
cold air arrives for the weekend along with additional snow
showers.

Aviation 15z Monday through Friday
Short term...VFR today with areas of MVFR ceilings and vsby in
scattered snow showers... Mainly in the mountains.VFR tonight
through Tuesday.

Long term... Ifr or lower ceilings in snow and rain Wednesday and
Thursday, with an end to precipitation and an improvement to
MVFR orVFR Friday. Additional showers are likely for hie and
leb which will see periods of MVFR in -shsn.

Marine
Short term...

10 am... Extended the gales SCA fz spray products as they are
into Tuesday morning, winds are unlikely to diminish much, and
may actually surge a bit this evening, and temps will only get
colder tonight.

Have dropped gales down to scas for casco bay and
will be continues gales for the outer waters and penobscot bay.

Long term... Scas will be needed for the bays Wednesday with
gales likely needed for the outer waters as a cold front moves
south from canada and into the coastal waters. Winds and seas
should both diminish by Thursday morning. We will also see
light freezing spray during this time.

Tides coastal flooding
Very little surge showing up 10 am, so may just have to deal
with some larger waves at high tide over the next couple hours.

Will be waiting for low tide around 0930z to see how much storm
surge is lingering. Strong offshore flow will help to diminish
whats left of this so thinking at this point is an advisory or
coastal flood statement should cover the situation.

Gyx watches warnings advisories

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.
