Synopsis
A storm system over the maritimes will gradually weaken and exit
the region tonight. Gusty winds behind this system will subside
tonight. High pressure follows this system for the weekend into
early next week. A frontal system will move across the region
around Tuesday or Wednesday. High pressure builds in for the end
of next week.

Near term until 6 am Saturday morning
715 pm update... Little change to the going forecast. Clearing
continues downwind of the mountains and this trend likely
continues this evening. A few upslope rain and snow showers in
the mountains remain, but these will continue wane overnight.

Winds will continue to subside.

Previously...

at 18z a 990 millibar low was centered vicinity of the gaspe
peninsula. Weak impulses and associated surface troughs continue
to pivot around this system today producing clouds along with a
few showers mainly over northern and eastern sections. Gusty
winds and cool temperatures are making for a chilly fall day.

Clouds should begin to thin out this evening following passage
of a weak impulse and with the loss of daytime heating. We'll
see some lingering upslope clouds and rain or snow showers
across the higher terrain with the remainder of the area
becoming mostly clear. Lows tonight will be in the 30s with a
few 40 degree temperatures along the coast and in southeast new
hampshire.

Short term 6 am Saturday morning through Saturday night
On Saturday... The storm system over the maritimes continues to
slowly pull away. We'll see some leftover upslope clouds across
the mountains with mainly sunny skies elsewhere. Once again a
northwest breeze but not as windy as today. Highs will range
from the upper 40s along the international border to the 50s
elsewhere. Saturday night will see clear skies and winds
becoming light as high pressure finally builds east into the
region. Temperatures will respond accordingly to the
radiational cooling with lows in the 20s to lower 30s with some late
night valley stratus and fog likely.

Long term Sunday through Friday
500 mb pattern across noam and surrounding oceans will tend to
remain fairly amplified with potential blocking sitting up
across N atlantic greenland region toward the end of next week.

Before that will initially see narrow but high amplitude ridge
setting up over the NE CONUS and into ERN canada, which should
for allow for a dry, and seasonably mild period Sunday into
Monday. Deepening trough to our west will slowly approach and
rotate NE across the area mid week, which will bring a chance of
some rain showers. Models indicating potential for narrow
ridging to develop again behind this system late in the week.

For the most part, 850 mb temps remain near to above normal.

Sunday and Monday are expected to be decent days with sfc high
holding over the region as remnants of TC nestor pass well S of
new england. Some cirrus from this system possible but otherwise
should be dry and at least partly sunny with highs both days in
the 50s to around 60 in S nh and on the coast. Given the
location of the sfc high, went below guidance a bit for lows
sun night, as we should see a decent set up for rad cooling.

Only issue will be possible clouds associated with nestor. Still
lows in the N should be 30-35, ranging to the upper 30s and low
40s in the s.

Fairly large and deepening 500 mb trough over central noam will
slowly shift NE Tue and wed, with main sfc low tracking to our
west, and potential for secondary low formation over the NE as
energy rotates around base of the trough. This will bring a
round of rain to the region in the tue-wed timeframe, although
exact timing and QPF still uncertain at this point. In the wake
of this system high pressure will build in from the SW for the
latter part of next week.

Aviation 23z Friday through Wednesday
Short term through Saturday night ...VFR with pockets of MVFR
across the mtns with sct -shra -shsn. NW surface wind gusting up
to 25 kt through 22z today before subsiding. BecomingVFR
throughout aft 22z Saturday. LCL ifr psb btw 08 and 12z Sunday
in valley stratus and fog.

Long term... MainlyVFR Sun through Mon night. Flight
restrictions possible at times tue-wed as frontal system moves
through.

Marine
Short term through Saturday night ... Nw flow and marginal sca
conditions continue. The short range models continue to show
another surge of wind late today early evening with a passing
surface trough so the SCA will remain in place and be extended
through late tonight. Thereafter... Bays and outer waters should
see conditions below sca.

Long term... May need SCA Tue into Wed as S flow ahead of
deepening low to our west picks up and pushes seas up as well.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 6 am edt Saturday for anz150>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.
