Synopsis
High pressure will build over the area through today. Tropical
moisture from the remnants of cindy and an approaching frontal
system will result in showers and thunderstorms Friday into Friday
night. A series of surface troughs or weak cold fronts will cross
the area this weekend into early next week bringing us the chance
of showers from time to time.

Near term until 6 pm this evening
1150 am... This update makes some adjustments to sky for this
afternoon to better cover the CU stratocu developing over the
terrain and tracking ewd this afternoon. Just some partly sunny
periods, especially in the mountains. Other than that, just
tweaks based on current obs.

925 am... No significant forecast changes. Some updates to
t TD sky based on current obs, and held back cloud cover for a
few hours late today early this evening. Overall, should be a
nice dry day with highs in the 70s to around 80, plenty of sun,
and low rh.

616 am... Minor estf update to ingest the current mesonet into
near term grids.

Prev disc...

at 06z... A weak frontal boundary extended from the gulf of maine
through southern new england and the mid atlantic region. A weak
1017 millibar high was centered over northwest pennsylvania. For
today... A sunny start as the weak surface high slides eastward.

We'll see mid and high clouds begin spreading into the area during
the afternoon as the stalled boundary to our south and west begins
to return as a warm front. High temperatures today should be in
the upper 70s and lower 80s... But a bit cooler across the mountains
as well as along the mid coast of maine.

Short term 6 pm this evening through 6 pm Friday
Tonight clouds will thicken as the warm front advances into the
region... With showers and scattered thunderstorms spreading
north and east across the area during the predawn hours of
Friday. Lows will be in the 50s across the mountains with lower
and mid 60s elsewhere. On Friday... Steadier shower and
thunderstorm activity will taper as the warm front lifts to
our north by afternoon as low pressure tracks eastward to the
north of lake ontario and into southern quebec. We'll see
showers and thunderstorms redevelop in the warm sector and with
a passing shortwave impulse during the afternoon. There could be
some brief torrential downpours as some of the tropical
moisture from the remnants of cindy gets entrained into the
storm system. It'll be a warm and humid day with dewpoints in
the 60s and lower 70s... With high temperatures in the lower and
mid 80s over the southern half of new hampshire and adjacent
southwest maine and in the 70s for the remainder.

Long term Friday night through Wednesday
Large scale troughing across much of the northern two-thirds of
the CONUS will continue to impact northern new england through
the weekend and the upcoming week. By early next week the trough
will have sharpened and pushed the bermuda high farther south as
it carves out a deeper trajectory... Dipping into the
southeastern states. The trough axis stays to our west through
at least Tuesday at which point GEFS and ECMWF ensemble
spaghetti plots become a huge jumble indicating disagreement
among the various members. Thus there is low confidence in the
forecast beyond the beginning of next week.

On Friday night showers and thunderstorms will be ongoing with a
warm front to our north and a cold front poised to cross the
region. The timing of this looks late for much strong
convection, but general thunderstorms with heavy rain and
nuisance flooding will be possible with plenty of tropical
moisture streaming from cindy to work with.

West winds should arrive Saturday morning bringing drier air
into the area. However, the remnants of cindy will be near nj
at this point. This additional moisture and lift will
strengthen the baroclinic zone in the vicinity, possibly
allowing for additional rainfall. A cold front sags south from
canada Sunday and lingers near the international border,
triggering more showers for the mountains and foothills. High
pressure will strengthen over the center of the CONUS with lower
pressure areas ringing the center. This will keep the gulf of
maine open for south to southeast winds to pump moisture into
new england resulting in more scattered showers and possibly a
few rumbles of thunder through midweek.

Temperatures will generally be around normal with readings in
the upper 60s to lower 80s for highs and overnight lows in the
upper 40s and 50s.

Aviation 16z Thursday through Monday
Short term through Friday ...VFR. Areas of MVFR developing
tonight in shra -tsra and continuing Friday.

Long term... Low ceilings will persist Saturday morning in
showers and fog. Conditions will improve toVFR Saturday outside
of the mountains with hie and leb possibly seeing some periods
of MVFR in lingering showers. On Sunday a cold front will
approach from the north bringing more MVFR conditions to hie,
leb and possibly aug. On Monday showers will encompass all of
the terminals with some heavier showers and thunderstorms
bringing visibilities and ceilings down to ifr at times.

Conditions improve Monday night.

Marine
Short term through Friday ... Winds seas will stay below sca
levels through tonight. On Friday we'll see strengthening
southerly flow ahead of a cold front with seas and wind gusts
outside the bays approaching scas during the afternoon and
evening.

Long term... Waves may remain in the 5-6 ft range for the
easternmost outer waters through Saturday. Otherwise conditions
are expected to remain below SCA criteria in the long term
marine forecast.

Tides coastal flooding
Hi astronomical high tides are expected Friday night and again
Saturday night. Tides may exceed minor flood levels and some
inundation is possible. If any surge or waves develop in
addition to this then impacts my increase.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
