Synopsis
Onshore flow will strengthen this evening ahead of an approaching
frontal system. Rain will overspread much of the area this evening
and become heavy at times overnight as an area of developing low
pressure tracks along the frontal boundary. Along the coast,
winds will become gusty. The storm system will quickly exit
into the maritimes by Wednesday afternoon with drier weather
behind it. A ridge of high pressure follows for Wednesday night
and Thursday. A cold front will cross the area Friday with a
few clouds and scattered showers. High pressure and drier air
follows for the upcoming weekend.

Near term until 7 pm this evening
At 18z a ridge of high pressure was draped across the maritimes
and northern and eastern maine. A 986 millibar low was over the
great lakes with a trailing frontal system through the lower
lakes and appalachians. The remnants of nestor were centered
well southeast of the 40n 70w benchmark. Clouds were gradually
thickening and lowering across the area in onshore flow ahead
of the advancing frontal system. For tonight... A coastal low
develops along the the front vicinity of DELMARVA then tracks
northeast as impulse GOES negative tilt. Rain overspreads the
area this evening then becomes heavy at times after midnight
with approach of the surface low and 60 kt low level jet. The
frontal system will also tap into some of the offshore moisture
from the remnants of nestor... Leading to higher QPF totals
mainly over our northern and eastern maine zones. QPF will range
from near one-half inch vicinity of the connecticut valley to
near two inches over our northern and eastern maine zones. We'll
see some gusty winds as well along the immediate coast... Mainly
from casco bay through the midcoast with stronger winds confined
to the area near penobscot bay. Lows will range from the mid
40s to lower 50s.

Short term 7 pm this evening through 6 pm Wednesday
On Wednesday... Rain tapers and clearing commences from
southwest to northeast by afternoon following passage of the
frontal boundary and coastal low. The exception should be
mountain sections where we'll hold on to clouds for the balance
of the day. Highs will range from the 50s across northern and
eastern sections... With the remainder of the area reaching the
lower 60s. Mostly clear and cooler Wednesday night as a ridge of
high pressure builds by to our south. Lows will range from the
mid 30s to around 40.

Long term Wednesday night through Tuesday
Unsettled weather conditions for the upcoming week, compared to
the dry weather of september.

A ridge will crest over the mid atlantic region Wednesday night,
allowing for mainly clear skies and breezy conditions. The
breeze will keep overnight lows in the upper 30s to lower 40s
across the region from north to south.

A weak surface cold front and cyclonic flow aloft will allow for
scattered showers Thursday into Friday. By Friday night, a fast
moving upper level trough will enter the region from the west.

This may bring a brief period of steady rain to southern areas.

A large area of high pressure will allow for dry weather over
the weekend. This will be followed by an upper level low
rounding the top of the ridge early next week with showers
spreading across the region once again. The 12z model suite
suggests there is quite a bit of uncertainty as to the track of
this system.

Aviation 20z Tuesday through Sunday
Short term...

conditions lowering to MVFR then ifr from SW to NE this evening
in ra and fog. Surface winds may gust up to 25 kt at coastal
terminals overnight. Conditions improving toVFR from SW to ne
Wednesday as low pressure and a frontal system slide offshore.

Long term...VFR conditions through Thursday night. MVFR
conditions possible Friday night into early Saturday as an upper
level trough crosses the region.

Marine
Short term through Wednesday night ... Scas in increasing onshore
flow ahead of an approaching frontal system. Tonight, 10-15 ft
seas develop along with gale force gusts across mid coast waters
before subsiding by mid day Wednesday. Scas then persist area
wide the remainder of Wednesday. Lingering SCA seas are likely
outside the bays Wednesday night.

Long term... Scas will linger into Thursday morning because of
gusty winds and seas.

Hydrology
A fast moving frontal system crosses overnight and early tomorrow
with models continuing to send a wave of moderate to heavy
rainfall S to NE across eastern nh into central maine. In
general models have consistently yielded 1-2" of rainfall over
these areas with a sharp cutoff north of the mountains owing to
favorable southeasterly downslope flow. Much of this could fall
over a 6 hr period however 3 hr FFG of 2-3" suggests water
impacts ought to be minimal except locally where fallen leaves
may block drains. Expect modest rises on local brooks and rivers
as a result at any rate, particularly across the headwaters of
the androscoggin, saco, and kennebec basins.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory from 8 pm this evening to 6 pm edt
Wednesday for anz153-154.

Gale warning from 2 am to 11 am edt Wednesday for anz150>152.

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.
