Area Forecast Discussion...UPDATED
National Weather Service Gray ME
1155 AM EDT Sat Jul 1 2017

.SYNOPSIS...
A cold front will approach the region from the west today with
another round of showers and thunderstorms expected. Some severe
thunderstorms will be possible...along with heavy rainfall and
localized flooding. Warm...but drier conditions are expected on
Sunday and Monday before cooler air courtesy of Canadian high
pressure arrives for Tuesday and Wednesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1155 AM Update...
Storms have weakened as they crossed the CT River Valley this
morning and coagulated into an area of heavy rain which is
affecting portions of southern and central NH. This area of
rain as well as cloud cover could interfere with later
convection but that remains to be seen. Have updated a few
products to remove fog wording and adjusted PoPs for current
radar trends. Also lowered high temperatures in a few spots
which may not see as much sun as expected.

9 AM Update...
A fast moving area of convection with an cluster of supercells
ahead of the main area of precipitation is moving through upper
NY state and into VT this morning. We are watching this
activity approach the CT River which may weaken the storms with
fog still in the valley. Regardless this is the type of storms
we saw last night...a mix of supercell/multicell which will
transition to a heavy rain threat eventually...and is indicative
of what we expect in a few hours. This short wave perturbation
moves along the warm front and exits this morning followed by a
stronger wave this afternoon. Expect strong instability and
good storm organization beginning early this afternoon based on
heating currently going on in southern NH and portions of
western ME.

Have added gusty winds back into the grids and adjusted other
weather parameters. Also increased PoPs over southern sections
this morning.

6 am.. just a minor adjustment to fog areas for this morning.
Afternoon damaging wind wording was added to western NH to
better match the day 1 SPC outlook.

At 3 am shower activity has mainly come to an end across the
forecast area. In the wake of the showers a very moist airmass
is in place with patchy fog expected to remain through sunrise.
A warm and humid airmass will remain in the area today allowing
for thunderstorms with heavy rain this afternoon. After sunrise
we will see a period of clearing skies through the southern
half of the area. This will allow temperatures to climb into the
80s in the south. A cold front approaches from the west this
afternoon. The upper level jet streak associated with this
front, in combination with the already moist and unstable
airmass will result in thunderstorms beginning to fire around
noon. These storms may become more organized and contain severe
wind gusts, especially in the south where heating is maximized.
The humid airmass will also allow for heavy rain within
thunderstorms - See Hydrology section below.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
As we move into the evening hours the cold front will finally
push through the CWA. Expect showers to linger through midnight
before clearing. Fog is again possible before the drier air mass
can finally begin to take hold on Sunday. Sunday will see high
temperatures climb to the upper 80s south to upper 70s north as
the westerly flow pushes drier air and clearing skies into the
region and prevents a sea breeze from taking hold.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
High Impact Weather Potential: Some threat for a thunderstorm far
southern NH on Monday...otherwise next chance for thunder will
arrive late Thursday through Friday.

Pattern: A glance at early morning water vapor imagery reveals a
ridge(+PNA)/trough pattern across western and central North
America...with weak ridging along the US East Coast.  Our recent
active weather has been related to energy ejecting from the trough
to our west...but this will change as we move into early next week
with this trough moving towards our longitude and introducing a
significantly drier airmass into the region.  Over the course of
next week...deterministic and ensemble guidance is in good agreement
that the longwave pattern will amplify...with a developing
longwave trough over the Gulf of Alaska...with subsequent
downstream ridge /and eventual trough/ development. The
developing ridge looks to set up a bit further east than where
it is currently...and be stronger...with the result being a
potentially stronger push of Canadian air by the end of this
forecast period and into next weekend. Ahead of this developing
trough...a brief period of building heights is likely around the
Thursday timeframe.

Pattern Implications: Trough location for Monday-Wednesday
suggests a drier period with seasonable temperatures.
Precipitation chances in this period will be more related to the
cool air aloft and thus will have more of a relationship to
terrain. Beyond this...moisture and precipitation chances will
increase as digging trough approaches from the west. Details
certainly differ between the various guidance solutions at this
range...but there is an increasing signal for precipitation in
the Thursday PM - Friday timeframe. The trend then turns
cooler/drier for next weekend.

The Details....

Monday: Secondary cold front and associated mid level shortwave move
through the region to start the week.  Based on the exact timing of
the front...there is some potential for a shower/storm to squeak
into southern NH before the front shifts south...however the better
chance for a few showers will be in the mountains given some upslope
enhancement and cooling temperatures aloft.  T8s will be falling
through the afternoon...but values in the AM near +14C south suggest
mid /upper?/ 80s will be attainable for southern NH and
southwestern ME with mid 70s to around 80 further north and
west. Clearing skies expected with drier air in place Monday
night allowing temps to fall into the 50s to lower 60s north to
south...right where they should be for this time of year.

Independence Day-Wednesday: High pressure crests over the region
during this period under northwest flow aloft.  PWATs -1 to -2 sigma
will accompany this high with two very nice days in store.  T8s +7-
10C on Tuesday rising a degree or so into Wednesday suggest highs
within a few degrees either side of climatology both days...just a
tad warmer Wednesday with afternoon sea-breezes along the coast.

Thursday-Friday:  High pressure pulls east and the pattern looks to
turn more active as we reach the end of the week.  Substantial
differences in the details arise at this point with the 00Z GFS/GGEM
developing a surface low ahead of digging Great Lakes shortwave as
it phases with cutoff low drifting through the Midwest.  This
surface low moves overhead or to our west with a period of
showers/thunderstorms likely. The 12Z ECMWF /with decent
support from the EC-EPS/ was much more progressive...with
increasing shower chances...but with any phasing occurring to
our east. The new 00Z ECMWF has trended closer to the GFS/GGEM
consensus. PoPs in the high chance category remain prudent
given decent but somewhat conflicting signals. Airmass aloft
will be warmer...and given the fact that rain will not likely
impact BOTH days significantly...could certainly see a warm
day...but confidence isn/t yet high on which. Can/t rule out
some severe potential at this range with impressive dynamics
upstream of the region suggesting good shear parameters.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
Short Term... The moist airmass will continue to impact the area
through the next 36 hours. LIFR fog will develop in the hours
before daylight before burning off in the early morning. By
midday look for clouds to develop from west to east becoming
widespread in the afternoon with periods of MVFR showers. The
showers will develop into thunderstorms, some strong which may
briefly drop conditions to IFR. As the front clears the area
overnight more IFR fog is likely in the river valley before VFR
is finally able to return for Sunday.

Long Term...
The Sunday night through Wednesday period looks predominately VFR.
Some morning fog is possible at HIE/LEB with HIE possibly seeing an
afternoon shower on Monday.

&&

.MARINE...
Short Term... A few 5 ft seas out there but generally below
small craft criteria. There is potential for wind gusts to 25 kts
to mix down later tonight as the front crosses the waters
however a more stable marine layer may prevent them from getting
to the surface and have opted not to issue a SCA for now.
Conditions will improve on Sunday.

Long Term...
Some risk for marginal small craft winds/waves in the outer
waters on Monday...otherwise winds/waves look to remain below
small craft levels through Wednesday. Risk for more widespread
small crafts to end the week if stronger low pressure advertised
by the GFS/GGEM materializes.

&&

.HYDROLOGY...
A flash flood watch remains in effect for the northern portion
of the forecast area. PWAT values are forecast to remain above
the 90th percentile for this date providing plenty of moisture.
The approaching front and jet streak will result in storms
moving parallel to the front.. from southwest to northeast
these training storms will have the potential to drop well over
2-3" of rain. After the past few days the ground remains quite
saturated with Flash Flood Guidance values generally around 1.5"
in 1 hour in the far north and up to 2.5" in an hour in the
south, these values could easily be exceeded if storms line up
and so the Flash Flood watch will continue. The trend is for the
axis of heaviest rain to align with the more mountainous areas
which are also the flashiest.

From a river point of view any rainfall is less of a concern as
it is unlikely to be widespread enough to cause a significant
rise in mainstem rivers. A few of the quicker responding rivers
such as the Pemi at Woodstock and the Swift at Roxbury will
need to be watched.
