Synopsis
A cold front will cross the area this evening. High pressure
will build across the region over the weekend. Low pressure will
approach on Monday.

Near term through Saturday
6:21 pm... A couple of areas of convection that we are closely
watching this evening. The first is ahead of the cold front and
is moving across parts of the saint john valley. The second area
is well in advance of the cold front and extends from northern
piscataquis county to northern washington county. The area of
greatest concern at this time is across northern areas. Expect
that the convection will weaken some with time this evening as
we lose the daytime heating, but the northern storms will likely
hold together better as they have more upper support with the
approaching cold front.

Previous discussion...

two separate areas of convection will affect the area this
evening. The first is a pre-frontal trough with thunderstorm
activity from northern somerset county towards northern
washington county. This area has benefited from strong shear,
diffluence aloft and the exit region of a potent upper level
jet. The best CAPE has been mostly towards the eastern border of
the state and this has been where the stronger storms have
organized. There is also differential heating with temperatures
in the mid to upper 80s south of the trough and in the 70s north
of the trough. Straight line hodographs have yielded an
interesting combination of right and left moving storms along
the trough. Convection with the pre-frontal trough will tend to
weaken with the loss of daytime heating and the upper jet
pushing eastward out of the area. The actual cold front is the
second area of convection which is bearing down on the saint
john valley. Will leave enhanced wording for gusty winds and
small hail until 9pm... After which thunderstorm activity will
diminish. Residual shower activity with the front should be out
of the area by midnight. After midnight, a very dry canadian air
mass will arrive with dew points dropping to the upper 30s and
40s.

All areas will benefit from much lower humidity on Saturday. An
onshore flow will ensure the warmest temperatures will be
towards the coast where lower 80s are expected. In contrast,
only upper 60s are forecast towards fort kent and madawaska.

There will be some fair weather cumulus at the top of a deep
mixed layer. This mixed layer will yield some gusts towards 20
mph.

Short term Saturday night through Monday
The consensus of longer range models keeps fair, cool, and dry
conditions to the rgn Sat ngt thru Sun eve as a sfc ridge of
can hi pres crosses the area into nb prov.

Clds will gradually increase from wsw to ene across the rgn late
sun ngt into Mon with shwrs rn slowly spreading into WRN ptns of
the fa from SRN qb by Mon aftn. Rather than to rely solely with
the latest 12z dtmnstc gfs, which was sig faster and further n
in bringing rnfl into the rgn, we kept with a consensus blend of
models which keeps the leading edge of shwrs from reaching far
nrn ptns of the rgn til late Mon aftn. Shwrs will then affect
all of the rgn Mon ngt thru Tue as the sfc low tracks alg the
downeast coast and the upper trof crosses all of the rgn. Most
qpf though, will occur ovr interior SW and cntrl highlands areas
spcly later Mon into Mon eve when there may be enough CAPE for
sct tstms, and the least across the far n. Subsequently, hi
temps Mon and Tue will be coolest ovr WRN most ptns of the rgn
on Mon and tue.

Long term Monday night through Friday
Shwrs should quickly exit the fa tues eve as the upper trof
moves E into the can maritimes. Fair and somewhat warmer
conditions will return for Wed as a mdtly strong S WV ridge alf
crosses the rgn. Longer range models cont to show a msly
unsettled pattern alf... Indicating another S WV trof complex
apchg and crossing the the rgn from S cntrl qb with additional
shwrs keeping hi temps at or below avg for this tm of season.

Aviation 22z Friday through Wednesday
Near term:VFR is expected outside of thunderstorms this
afternoon and evening. No prolonged CIGS are expected Saturday,
but northwest winds may gust towards 20 kt.

Short to long term:VFR conditions xpctd all TAF sites with
MVFR clgs vsbys possible with heavier shwrs Mon aftn thru
tue.

Marine
Near term: no significant weather is expected. Winds will stay
up towards 15 kts ahead of the cold front this evening.

Short to long term: no immediate hdlns slated for these ptns of
the fcst for our waters with WV hts ovr outer most waters apchg
5 ft ovr outer most waters Mon aftn into Mon ngt with primary
wv pds ranging from 5 to 9 sec. Went with about 85 percent of
ww3 WV guidance.

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.
