Synopsis
High pressure will build to the south of the region through
tonight before sliding to the east on Tuesday. A strong cold
front will move across the region Tuesday night and early
Wednesday. High pressure and drier air follows the front
Wednesday night through Friday.

Near term through Tuesday
10pm update..Forecast is on track. Skies remain mostly clear.

6pm update... Just a minor update to put in the latest
observations. Clear skies tonight will allow for some fog to
form in valleys.

At 18z... A ridge of high pressure was draped across new england.

Outside of a few fair weather cumulus... GOES imagery showed fair
skies across the region. For tonight... The ridge retreats offshore
to our south. Outside of a few warm air advection clouds... A
mainly clear night with patchy valley stratus and fog developing
in the predawn hours. Lows tonight will be mainly in the 60s.

Short term Tuesday night
On Tuesday... Strengthening southwest flow between the offshore
high and an approaching cold front will provide a hot and humid
day to the forecast area. Highs will be well into the 80s with a
few 90 degree readings over southeast new hampshire into
adjacent interior york county maine. Heat indices over southeast
new hampshire should peak in the lower 90s and fall short of
advisory threshold. The best forcing and wind field will be to
our west although a few airmass storms may develop during the
afternoon over interior nh into the mountains of western maine
where a few storms could produce gusty winds. The more organized
convection with the front should arrive during the evening hours
or after dusk across much of the area... Which should mitigate
the severe convective threat. Convection should end from west
to east overnight as the front sweeps offshore in the predawn
hours of Wednesday.

Long term Wednesday through Monday
The pattern setting up in the extended portends to rather quiet
and benign weather. Front sweeps offshore Wednesday morning with
any showers coming to an end early. Upper level trough will hang
around thurs and Fri with which will allow for periods of bkn
clouds and some showers, mainly in the mountains, especially
Friday. Otherwise cool high pressure moves in for the weekend.

Aviation 02z Tuesday through Saturday
Short term through Tuesday night ...VFR... With sct MVFR and
lcl ifr btw 08 - 12z Tue in valley fog. Late Tue and Tue night
conditions lowering to MVFR with LCL ifr in developing showers
and scattered thunderstorms ahead of an approaching cold front.

Long term... Any ifr should lift toVFR prior to noon Wednesday.

Otherwise,VFR conditions should prevail thu-sat with local
MVFR in lower clouds and showers, especially in the mountains
possible.

Marine
Short term through Tuesday night ... Winds and seas are
expected to remain below small craft through early Tuesday as
surface high pressure builds to our south. By late Tue and tue
night an increasing south to southwest flow ahead of the
approaching cold front will allow SCA conditions to develop.

Long term... SCA conditions Wednesday in the wake of a cold
front should wane later Wed morning with seas diminishing during
the afternoon. Otherwise, tranquil conditions are expected on
the waters thu-sat.

Tides coastal flooding
We're in the period of high astronomical tides for the month of
august. The high tides of potential concern (referencing
portland harbor where flood stage is 12.0 ft mllw) are:
1140 pm tonight... .11.2 ft mllw
1231 am Wednesday. 11.1 ft mllw
the Tuesday night high tide (1231 am Wednesday) could see some
splashover as onshore flow and seas increase ahead of an
approaching cold front.

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.
