Synopsis
High pressure building into the region today and tonight will
deliver cold temperatures across the region. Expect a brief warm
up on Tuesday before another cold front moves through the area
on Wednesday bringing a return to colder conditions that should
last through Friday. A brief warmup expected Saturday with
scattered showers ahead of another approaching cold front that
arrives Saturday night. High pressure delivers colder and drier
air for Sunday.

Near term until 6 pm this evening
Update... Morning light is allowing the use of some webcams
across nh and a better gauge of where accumulating snow is
taking place. I have upped pop to high chance and likely in most
of the high terrain now. This includes some light accumulations
into the foothills... Especially in oxford and franklin counties.

Previous discussion... Secondary S WV trof will cross the area
early today. This will renew CAA and allow winds to be quite
gusty again during the afternoon. I am not expecting it to be as
windy as yesterday... With generally 25 to 30 kt gusts. With
favorable dendritic snow growth temps in the low levels and
abundant low level moisture... Upslope snow showers will continue
thru most of the day. Flow also becomes more wly with
time... And that may bring more lake enhanced moisture into wrn
zones. I have expanded slight chance and chance pop... As well as
brought pop into swrn nh where lake enhanced bands of snow are
drifting a little more nly than earlier in the night. Froude
numbers remain greater than 1 in the CAA regime... So snow
showers should consistently be able to top the green mtns and
drift into WRN nh... As well as top the white mtns and sneak into
the foothills. Some light accumulations are possible in WRN nh
nwd thru the white mtns.

Short term 6 pm this evening through 6 pm Tuesday
Weak S WV ridging aloft and surface high to the S trying to nose
into the area will allow winds to diminish around sunset. There
is a window for some radiational cooling tonight as warm front
lifts thru the area aloft and before return flow really picks up
in the boundary layer. I have generally stayed with the cooler
guidance sources... And also show a small non-diurnal trend late
tonight as return flow increases towards dawn.

Behind the warm front we also see a much drier low level air
mass... Which should allow any remaining clouds and snow showers
in the mtns to scatter out dry up. Return flow aloft will also
bring in some warmer temps... And allow even shallow mixing to
send the SRN and coastal zones on a run to the 50s.

Long term Tuesday night through Sunday
A warm southwest flow Tue night into early Wed ahead of an
approaching cold front. The cold front will move rapidly through
the region Wed with scattered showers expected. In the mountains
some of the showers will likely change to snow showers as the
caa occurs during the day. Not much QPF is expected with the
passage of the front as per models suggest. Models all indicate
the heavier band of rain will stay well offshore ahead of the
front. Behind the front, a large arctic ridge of surface high
pressure will build into the region Wed night through Friday with
dry conditions and much colder temps.

All models in general agreement about carving out a general broad long
wave trof position across the eastern us. This will mean
generally colder temps and mainly dry conditions and storm free.

The only exception being Sat as a brief warm southwest flow
develops scattered showers ahead of the next shot of cold air as
the upper trof gets reinforced bringing another shot of cold
arctic air across the region by Sunday.

Aviation 13z Monday through Friday
Short term...VFR conditions expected to prevail thru tue. Local
MVFR is possible near hie as upslope shsn continue for much of
the day. Surface wind gusts at or above 25 kts expected this
afternoon at all terminals. Winds gradually late in the day and
overnight... And shift more swly. Upslope clouds and shsn come to
an end early Tue as much drier air moves into the area.

Long term... MVFR conditions expected Wednesday as a strong cold
front moves through the region.VFR conditions will return by late
Wednesday and continue into early Saturday.

Marine
Short term... Currently in a bit of a lull in wind speeds across
the waters. That will be short lived however... As a secondary
s WV trof crosses the area today and renews stronger NW wind
gusts. Wind gusts will reach marginal gales outside the bays
around mid morning... So I have just extended the current gale
warning thru this evening. SCA will continue in the bays for the
same time. Tue winds becomes more swly and may allow winds to
drop below SCA thresholds... Though seas will likely remain near
or above 5 ft.

Long term... Southwest flow may approach SCA criteria Tue night
ahead of an approaching cold front. The front moves across the
waters Wednesday. By Wednesday night a north to northwest flow may
briefly reach SCA conditions over the outer waters. High pressure settles
over the waters Thursday and Friday with light winds.

Gyx watches warnings advisories
Me... None.

Nh... None.

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

Gale warning until 10 pm est this evening 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.
