Synopsis
A cold front will exit across the gulf of maine overnight into
Friday. High pressure will build across the region Saturday and
Sunday, then slowly move east Monday and Tuesday. Low pressure
from the west will begin to approach on Wednesday.

Near term through Friday
125 am update...

clouds still streaming up along the cold front right along
the coast as seen on the latest satl imagery. Some clouds moving
into western sections W bases of 5k ft. Clouds to gradually
thin out overnight as drier air continues its trek southward.

Dewpoints still in the low mid 60s from bangor to the coast
w that drier air just to the north. Slight adjustments were
made to the dewpoints and temps to fit the latest obs, but
otherwise, forecast looking good.

Previous discussion...

the parent low of the system will remain over quebec. A trough
will rotate around the low over quebec and move through northern
maine Friday morning. High pressure will build in behind the
trough and will remain through the end of the period.

Loaded a blend of the GFS nam ECMWF gem to smooth out the minor
differences in the models.

Short term Friday night through Sunday night
Fri eve, a S WV trof will rotate across the fa from a semi-
closed mid lvl low ovr the gulf of st lawrence, bringing cldnss
to msly NRN ptns of the fa as well as isold to sct lgt rn shwrs
across the far n. This S WV will track ese of the fa into nb
prov by late Fri ngt... But allowing some sc cld cvr to spread
swrd with a NW cool advcn breeze for the remainder of the ngt.

Sat will be ptly to msly sunny. Hi temps Sat will be coolest
this upcoming pd accompanied by breezy N winds, with llvl cool
advcn only becmg near neutral late in the day.

With the sfc hi xpctd to crest right ovr the rgn by late Sat ngt,
clr skies, lgt winds, and dry airmass conditions should allow
for good radiational cooling spcly for NRN vly rgns where ovrngt
lows of lower 40s and even upper 30s for coldest lctns of the
wrn st john vly are likely by erly Sun morn. Otherwise, Sun durg
dylgt hrs looks to be sunny with a decent recovery of temps to
lower to mid 70s for aftn highs for all low trrn lctns as sfc
high pres slowly drifts E of the rgn.

Long term Monday through Thursday
Longer range models are in better agreement on tdy's 12z model
cycle that Sun ngt thru Tue looks to be fair and dry attm.

Blended long range models then show increasing cldnss later tue
ngt into Wed and the next chc of shwrs late Wed into thu.

The main uncertainty late in the long range is the future track
of the system currently just SW of the bahamas, with this
uncertainty including whether the system will be tropical or non
tropical as it moves into higher latitudes in the N atlc basin.

Most model solutions for the time being show this system
tracking well S and E of nova scotia late next week, but given
long range model uncertainty of track and tmg of systems
movg N out of the tropics this far out in tm, we will be keeping
an eye on this system thru the weekend into erly next week.

Aviation 06z Friday through Tuesday
Near term: tonight through Friday night…
tonight...VFR.

Friday...VFR. Breezy out of the northwest.

Short term: Fri night through tue...VFR all sites except MVFR
clgs possible kfve and kcar Fri eve. Mainly lgt winds.

Marine
Near term: a southerly swell will bring seas up tonight, however
winds and seas will remain below small craft advisory levels
through the period.

Short term: no hdlns anticipated attm. Went with about 80 to 90
percent of ww3 nwps WV ht guidance blend throughout, with nwps
emphasized for near shore waters. WV spectral groups will be at
arnd 6 sec for short fetch wind directions in the vcnty of our
coastal waters and 10 to 12 sec for residual long pd swell from
low pres systems well out into the open atlc.

Car 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.
