Synopsis
A cold front will sweep offshore early tonight. High pressure
follows this front overnight through Monday and will slide
offshore on Tuesday. A cold front will move in from the west
Tuesday night and will cross the region on Wednesday. High
pressure will build in behind the front Wednesday night through
Friday.

Near term through tonight
At 18z... A 1007 millibar low was off the downeast coast with a
trailing cold front through the gulf of maine. A 1001 millibar
low was centered over northern quebec with a trailing cold front
through the eastern great lakes. We're seeing gradual clearing
today behind the departing disturbance over the gulf of maine.

However, heating and the approaching cold front may trigger a
brief shower isolated thunderstorm through early tonight mainly
across the higher terrain. Overnight... Partly cloudy skies with
patchy fog and valley stratus developing in wake of cold front
and shortwave impulse sweeping offshore.

Short term Sunday through Sunday night
For Sunday... Ridging takes hold although we'll see a few upslope
clouds across the higher terrain. It'll be a warm day with highs
ranging from the 70s across the mountains... To lower and mid 80s
elsewhere. Partly cloudy Sunday night with some patchy late
night fog and lows in the 50s to lower 60s. &&

Long term Monday through Friday
Models remain in fairly good agreement today on extended forecast
for next week. High pressure will crest over the region early
Monday before shifting offshore south of new england. Return flow
will bring warmer and more humid air back into the northeast
through the day under mostly sunny skies. Highs on Monday will
generally range through the 80s.

Summer-like weather will continue Monday night and Tuesday.

Looking for partly cloudy skies Monday night with lows in the
lower to mid 60s. Tuesday will start off mostly sunny with high
clouds on the increase in the afternoon as a cold front
approaches from the west. Looking like a hot one with highs in the
80s to lower 90s. May see some convective activity reaching far
northwest zones by late in the day but expect a majority of the
forecast area to see a dry day.

Cold front will push in from the west Tuesday night. Looking for
showers and thunderstorms overnight some of which could be severe
with heavy rainfall. Moderate to strong shear will combine with
pwat's approaching 2 inches to produce possible damaging winds
and heavy rainfall. Although timing of the front not ideal...

strong dynamics associted with this shortwave should sustain
convection well into the evening and overnight. Looking for a very
warm and humid night with lows in the 60s to lower 70s.

Cold front will slow as it moves through the region early Wednesday
but should finally move offshore by Wednesday afternoon. Highs on
Wednesday will range from the mid 70s north to the mid 80s south.

Skies will be mostly clear Wednesday night as high pressure begins
building in from the west. Should see much more comfortable
conditions as cooler and drier air shifts into the region on a
northwest flow.

High pressure will dominate the weather for the rest of the week
and into the weekend. Upper trough settling into the northeast will
result in a mix of Sun and clouds during the days with mostly clear
and cool conditions at night. Highs Thursday through Saturday will
range through the 70s with lows overnight in the upper 40s to mid
50s.

Aviation 18z Saturday through Thursday
Short term through 12z Monday ... Lingering MVFR over mid coast
maine will becomeVFR by early evening. Overnight... Areas of
MVFR and LCL ifr will redevelop in stratus and fog. BcmgVFR
throughout Sunday morning with LCL ifr psb btw 08 - 12z Mon in
valley stratus and fog.

Long term...

showers and thunderstorms Tuesday night. BecomingVFR for
Wednesday through Thursday.

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.
