Synopsis
A coastal low will parallel the coast and cross the gulf of
maine later today before exiting into the maritimes. An upper
level disturbance will cross the region Saturday. Canadian high
pressure builds into the region Sunday before a fast moving area
of low pressure develops over the region Sunday night. An
arctic front will cross the region late Monday, followed by high
pressure building into the region through midweek.

Near term until 6 pm this evening
1230 pm update: have dropped the winter storm warnings for
southern nh and extreme southwest me as the snow has tapered off
to snow showers as wraparound snows have now moved off to the
north and east.

10 am update: continue to watch wraparound band of pcpn
developing over the area as expected. Nice comma head continues
development north of the low and mid level low which is
centered over CAPE cod and moving northeast. Expect a band of
very heavy QPF to develop but just stay a few miles off the me
coast late this morning and early afternoon with the comma head,
if this ends up slightly further W then coastal areas would get
higher amts but for now will plan on axis of hviest QPF staying
just offshore. Meanwhile widespread snow to continue over the
rest of the area as the wraparound with light to moderate
snowfall occurs. Ptype all snow now except over coastal areas
along the midcoast as CAA continues to be drawn south into the
developing low off the coast. Lowered temps for the next few
hours and also changed all ptype to snow except along the immediate
midcoast areas.

830 am update: second round of snow developing as low level low
currently centered near block island, ri continues to work
vertically and enhancing low low wraparound snowfall across much
of the area. IR Sat imagery showing a developing comma head
which should help to further enhance snowfall for the next few
hours into early afternoon. A couple inches additional snowfall
possible in some areas. Any mixed pcpn should change back to
snow in the next few hours as cold air filters into southeast nh
and parts of coastal me.

600 am... For this estf update i've allowed the winter weather
advisory for seacoast nh to expire an hour early. They've warmed
above freezing and little in the way of additional frozen freezing
precipitation is expected there. The dry slot on GOES imagery is
translating eastward and will exit the forecast area shortly.

There should be one more round of steadier precipitation across
the area this morning... Especially across northern and western
sections associated with the shortwave.

Prev disc...

at 06z... A 999 millibar coastal low was vicinity of the delmarva
with 3 hour pressure falls in advance of this feature
approaching 10 millibars south of CAPE cod. GOES water vapor
loop showed the associated shortwave over western pa with a dry
slot pushing northward through southern and central new england.

Widespread banded precipitation was noted on NWS doppler radar
mosaic across the region at moment. A complicated forecast as
some warmer air briefly works in aloft this morning in advance
of the strengthening surface low. This will cause snow to mix
with sleet and rain light freezing rain at times as
precipitation lightens in intensity. The coastal front is
approaching the maine mid coast and may briefly come onshore
there changing precipitation to rain. All told... This should
result in some wide variation in snow amounts today over
relatively short distances. The steadier precipitation should
end by early afternoon as the shortwave exits into new
brunswick. Our issues with mixed precipitation should end by
midday as the surface low tracks into the gulf of maine. The
easterly flow will become northerly even at the coast at that
time drawing colder air southward across the entire forecast
area. No changes to winter headlines at this time.

Short term 6 pm this evening through 6 pm Saturday
Lingering clouds and a few snow showers tonight mainly across
northern new hampshire and much of our northern and eastern
maine counties in proximity to a weak surface trough and with
moist upslope flow across the higher terrain. On Saturday... Upslope
flow with some clouds and snow showers for the higher terrain.

Otherwise a partly sunny start to the weekend with highs in the
30s across the mountains with lower and mid 40s elsewhere.

Long term Saturday night through Thursday
After a busy beginning of the weekend, the long term forecast
is free of significant systems. We will see snow, but outside of
the mountains the only time frame will be Sunday night into
Monday morning, and at this time, amounts look light. So more
nuisance type precipitation. Additionally clouds and snow
showers over the mountains will pick up additional accumulations
throughout the week. Otherwise temperatures will be relatively
warm, with highs above normal several days.

A cold front will near the region from the northwest late
Saturday night, bringing additional light snow showers and
cloudiness to portions of northwestern maine and new hampshire.

The front weakens as high pressure builds in Sunday. Sunday
will be precipitation free in downsloping areas, with some
sunny skies before clouds return from the south. As the high
quickly moves offshore during the day Sunday, weak WAA will
begin in association with a weak system moving through the ohio
valley.

Light showers will accompany this system, mainly for southern
sections of the region. The p-type will be snow with plenty of
cold air in place, with rain offshore. Again as mentioned
earlier amounts look less than 3" at this time. Colder air will
stay locked in the mountains, with overnight lows ranging from
the teens far north to 20s along the coast, and mid to upper 20s
over southern nh for Monday morning. The cold push behind this
system will make Monday night through Wednesday's temperatures
well below normal.

For the remainder of the forecast, the long term models are
having trouble with the robustness of the upper level trough
and associated waves affecting the northeastern states. Cyclonic
flow does look to stay overhead, bringing periods of cloudiness
and showers, mainly for the peaks. Around midweek the trough
will begin to dig towards the northeastern conus, bringing some
showers for thanksgiving day, mainly across the north.

Aviation 18z Friday through Wednesday
Short term through Saturday ... Ifr and lifr in sn with some
sleet and rain vicinity of the coast... Slowly improving toVFR
late this morning.VFR conditions in the afternoon into
tonight... Except in the mountains where MVFR conditions may
persist in snow showers. Gusty northwest winds will develop this
afternoon into the evening as an ocean low exits into the
maritimes.

Long term... Conditions lowering to ifr in snow Sunday night.

Improving toVFR outside of mountain terminals which will see
snow showers Monday and Tuesday.

Marine
Short term through Saturday ... Gales today with seas winds
diminishing to scas tonight into late Saturday.

Long term... We may briefly see a few gusts to 25 kts
periodically Monday, mainly in penobscot bay and the far eastern
outer waters. After that winds and seas increase across the
board and solid scas may be newed.

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.
