Synopsis
High pressure will retreat well offshore today. A warm front
will lift into the region today as low pressure shifts into
southern quebec. The low will drop southeast through the region
tonight before moving offshore on Friday. High pressure will
build in from the west Friday night and will crest over the
region early Saturday before shifting offshore. A warm front
will push east through the region Saturday night and will be
followed by a cold front late on Sunday. High pressure will
build in from the west Sunday night and Monday. Another warm
front will lift into the region on Tuesday.

Near term until 6 pm this evening
10am update... Made some minor changes with this update, mainly
with sky cover and temperatures. Temperatures are climbing a bit
faster than anticipated so adjusted the warming trend to match
observations. Skies have cleared at this hour over much of
western me, but clouds will quickly return later this afternoon
as the warm front approaches. Rest of the forecast looks on
track at this time.

540 am... Minor estf update to reflect current radar trends and
mesonet in near term grids.

Prev disc...

at 06z... A 1027 millibar high was centered south of CAPE cod. A
1003 millibar low was over minnesota with a warm front through
the upper midwest and a trailing cold front through the upper
mississippi valley. GOES water vapor imagery showed a weakening
shortwave impulse along the ontario-quebec racing east over the
top of the flattening upper ridge. A band of mainly mid and
high clouds was racing east into the area at moment. NWS doppler
radar mosaic showed a weakening area of light showers sprinkles
with this feature. For today... The impulse crosses the area and
exits the coast by shortly after dawn. Behind it some
subsidence and a few sunny periods through late morning. The
next more substantial impulse near lake superior this morning
will ride east-southeast and into new england late today. At the
surface... Low pressure will track east to near montreal by
evening. The surface warm front will push north through upstate
new york with the trailing cold front close behind. Clouds will
thicken across our area by afternoon ahead of this feature with
showers and scattered thunderstorms spreading east across the
area during the mid and late afternoon hours. Southerly flow
will warm us into the 60s with a few lower 70s over new
hampshire. The warm sector and best instability along with
strongest wind field remains to our west today and expect strong
convection to remain there as well.

Short term 6 pm this evening through 6 pm Friday
Low pressure and occluding frontal system rides southeast across
the area tonight. We'll see showers and a few thunderstorms but
with convection elevated and best instability remaining to our
south and west the potential for any severe storms is extremely
low. The locally heavy rainfall along and to the north of the
low track may dump as much as another inch across the headwaters
in northern new hampshire and western maine. Not enough for
flooding but sufficient to push some of the rivers and streams
towards bankfull late tonight and Friday. Lows tonight ranging
from near 50 along the international border with lower and mid
50s elsewhere. Precipitation will taper overnight and the
surface low should be exiting the maine mid coast by dawn. On
Friday... Decreasing clouds with any lingering showers ending as
the upper low slides offshore and is replaced by rising heights
and a ridge of high pressure. A gusty northerly flow of drier
air should diminish by late in the day. Highs will range from
the upper 50s to mid 60s... With readings near 70 over southern
new hampshire.

Long term Friday night through Wednesday
High pressure builds in Friday night into Saturday morning
allowing for fair weather during that time frame. A short wave
trough and associated warm front moves toward the region on
Saturday. There are however fairly significant differences in
timing from various members of the 00z model suite. Will take a
compromise at this point and keep a good portion of Saturday dry
before introducing rain from west to east during the mid to late
afternoon hours. Whatever the case may be with onset times the
heaviest rain is expected Saturday night. In addition, elevated
instability should be sufficient for at least a few
thunderstorms, especially across southern zones.

The short wave trough moves across the forecast area on
Sunday which will allow for continued cloudy weather and
occasional rain showers. As the progressive pattern continues,
Monday looks to feature fair weather as short wave ridging moves
overhead. Thereafter, timing issues within the 00z guidance
suite reappear as there is plenty of disagreement on how fast
the ridging will break down allowing for more wet weather to
return. At this time, will compromise and center highest pops
for more showers and thunderstorms on Tuesday night.

Aviation 14z Thursday through Monday
Short term through Friday ...VFR. Developing MVFR CIGS in
shra -tsra late today with LCL ifr. Conditions gradually
improving toVFR throughout on fri. Gusty northerly wind Friday
to 25 kt.

Long term...VFR conditions are expected Friday night and
Saturday morning as high pressure moves overhead. This high will
move off to the east Saturday afternoon allowing a warm front to
approach from the west. Increasing chances for showers will
will gradually lower conditions to MVFR late Saturday afternoon
but especially Saturday night where periods of ifr conditions
are possible in rain and embedded thunderstorms. Local MVFR
conditions are expected Sunday in showers.VFR conditions return
Sunday night and Monday.

Marine
Short term through Friday ... Winds and seas increase later today
ahead of a warm front but should stay below SCA even outside the
bays. Behind the departing system later tonight and Friday the
developing northerly flow should produce SCA conditions outside
the bays.

Long term... Small craft conditions will be possible Saturday
night as southwesterly winds increase ahead of approaching low
pressure.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory from 11 pm this evening to 6 pm edt

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.
