Synopsis
A strong cold front has moved through new hampshire and western
maine with a cold west wind behind it. Expect the temperature to
fall into the 20s tonight and not get out of the 30s on Monday
as the cold air mass will still be overhead. Expect a brief warm
up on Tuesday before another cold front moves through the area
on Wednesday bringing a return to colder conditions which should
last into the weekend.

Near term until 6 am Monday morning
Update...

winds will continue to slowly diminish this evening. Have
lowered the wind advisories as of late this evening. Most
locations have decoupled. Very strong winds continue over the
higher mountainous terrain and is reflected in the recreational
forecast. Occasionally, some communities have reported light
winds only to report 30+ mph at times.

Clouds and a few snow showers continue over the northwestern
third of our forecast area. Have upped pops for this region as
well as the foothills with some light accumulating snows
possible.

Minor adjustments made to cloud and temperature forecast.

Otherwise very little change to the new forecast package.

Prev disc...

cold front has made its way through the entire forecast area
with winds making an abrupt shift to the west and temperatures
dropping. It's rather rare to see such a sharp cold front in new
england where interactions with terrain and complex multi-
frontal systems usually mean fronts go through in stages. But
this one has been easy to follow in surface observations which
have shown temperatures falling rapidly behind the front even
during the middle of the day. The strong westerly winds continue
into the evening and overnight hours as cold advection
continues. Any lingering showers will be tied to the terrain and
be falling in the form of snow. Low temperatures tonight will
generally be in the 20s as the strong push of cold air will keep
the low levels well mixed.

Short term 6 am Monday morning through Monday night
It will be windy again tomorrow, but not as windy as today.

Temperatures will not get out of the 30s and may stay in the 20s
to the north of the mountains where the core of the cold air is
banked up against the terrain. Ridge of high pressure noses into
the area overnight Monday night, allowing winds to finally die
off. This could lead to some good radiational cooling and cold
temperatures in spots that are able to go completely calm,
mainly in the east and north.

Long term Tuesday through Sunday
Strong SW flow develops Tuesday with a significant shortwave moving
through on Wednesday. Moisture returns ahead of the system on
Tuesday as a warm front lifts ne. An associated cold front will
shift offshore Tuesday night Wednesday morning. Temperatures ahead
of the front Tuesday will be similar in pattern to today, with 50s
south and 40s north. Temperatures will continue to tumble the next
few days thereafter as drier and cooler air funnels in from the
north.

Large scale troughing will remain across southeastern canada and the
northeastern states through the end of the week. At the surface
sprawling high pressure will build across the southern states and ne
into the midwest and new england.

Aviation 04z Monday through Friday
Short term... Gusty west winds will diminish a bit overnight,
but not completely. Will see an increase in gusts again on
Monday before the winds finally die off Monday night.VFR
conditions are expected except for MVFR ceilings north of the
white mountains.

Long term...VFR Tuesday. Cold front arrives on Wednesday and
could see MVFR or ifr conditions in light rain ahead of the
front. Expect improvement behind the front for Thursday and
Friday.

Marine
Short term... Cold west winds will gust up to 45 kt through this
evening along the outer waters. Have extended the gales until 5
am over the outer waters, with scas now on the bays.

Long term... Southwesterly flow expected on Tuesday before a cold
front moves across the waters on Wednesday. Northerly winds
behind this cold front could briefly reach advisory levels
Wednesday night.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 5 am est Monday for anz151-153.

Gale warning until 5 am est Monday 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.
