Synopsis
A major nor'easter will move across new hampshire and maine
tonight into Thursday. Heavy rain and strong winds are expected
across the area with damaging winds possible along the coast.

The low will move out on Friday with upslope showers lingering
to start the weekend. High pressure will build in for the
weekend before another cold front moves through next week.

Near term until 6 am Thursday morning
Update...

have updated the forecast based on current conditions and latest
mesoscale models. Latest radar imagery indicates rain now over
western new england and continuing to press eastward. Rain will
reach southwestern new hampshire early this evening, before
spreading to the north and east tonight. Rain and wind will
increase in intensity during the overnight hours. Latest
mesoscale models has the rainfall rates and wind fields
beginning to diminish around 12z in most areas, with heavy rain
continuing for a few more hours in the far north.

Prev disc...

at 18z... A 997 millibar low was in the vicinity of georgian bay
with a trailing cold front through the mid atlantic region and
delmarva. Three hour pressure falls were on the order of 6
millibars vicinity of the DELMARVA as a 1000 millibar secondary
low was rapidly developing in response to upper system
transitioning to negative tilt. Latest numericals are in good
agreement on evolution and track of the coastal system. Clouds
will quickly overspread the area this evening ahead of the
deepening coastal low will rain developing from southwest to
northeast across the entire area by shortly after midnight. The
strong onshore flow and upslope will result in rainfall heavy at
times ahead of the approaching 70 knot low level jet. By
morning... The 973 millibar low will be centered over southern
new hampshire with heavier precipitation quickly tapering to
light rain or showers as dry slot wraps into the area. There
will be a narrow timeframe of strong winds with the low level
jet with coastal sections likely to see wind gusts of warning or
advisory criteria. Higher terrain above 1500 feet may also see
a brief period of winds near 45 mph towards morning. While the
band of heavy rain will be brief... Amounts of 1 to 2 inches are
likely across southern and western new hampshire with href
suggesting some localized 3 or 4 inch amounts. Have issued a
flood watch for that area overnight into Thursday.

Short term 6 am Thursday morning through Thursday night
On Thursday... We'll see a lull in the winds as the low center
meanders across the area with areas of light rain or showers
pivoting around it. Highs will range from the upper 40s to mid
50s. Across the white mountains... The summits will likely see a
decent amount of wet snow as the column cools during the day.

Thursday night the system will begin to exit to our north and
east with gusty westerly flow developing in the cold air
advection behind this system. We'll see some leftover rain and
snow showers across the higher terrain with snow levels
gradually lowering overnight. Lows will range from the mid 30s
to lower 40s.

Long term Friday through Wednesday
Overview: the nor'easter should be out of our region by Friday
morning, but northwesterly flow in its wake will keep scattered rain
or snow showers in the mountains throughout the day. High
pressure arrives for the weekend and holds through Monday with
good radiational cooling conditions expected at night. By
Tuesday morning, a cold front and mid-level disturbance are
expected to be approaching our region, bringing a round of rain
and showers that will persist through Tuesday night.

Impacts: no significant impacts anticipated, but the mid-week system
has some potential to produce significant rainfall.

Details: Friday morning begins with our region on the backside of the
nor'easter as it moves through new brunswick. As is typical
with these systems, the flow will be rather brisk out of the
northwest. While much of our region will be dry under this
regime, scattered showers will remain possible throughout the
day in the mountains of northern nh and northwestern me. While
lower elevations will likely remain warm enough to only see
rain, higher elevations look to be cold enough for light (<0.5
inch) accumulations of snow.

Chances for precipitation will gradually wane Friday night as the low
continues to pull away and high pressure builds into our
region. The high pressure is nearly overhead by Saturday evening
and it should remain there through Saturday night. Early
Sunday, a cold front extending south from a low pressure system
pulling north into canada will wash out before it arrives in our
region; high pressure again builds into our region through the
day on Sunday. Overall, the weekend looks rather nice with
mostly sunny skies and seasonable temperatures. With high
pressure centered nearly overhead Saturday night, have gone
cooler than the blended guidance as it looks like a potentially
ideal setup for radiational cooling conditions.

The surface high pressure gets pushed to the north on Monday as
another potent low pressure system moves toward the great lakes.

Our region should remain dry albeit with clouds increasing
during the evening. However, as the system's cold front
approaches, precipitation chances will begin to increase Monday
night an continue to increase from south to north during the day
on Tuesday. There is some disagreement on when the
precipitation may end between the faster GFS and the slower
euro, but Tuesday looks like the most likely period for
precipitation with lower pops in the forecast Tuesday night to
account for that uncertainty.

Overall, temperatures will be seasonable to slightly above
average for the long term period with the exception of the
weekend low temperatures.

Aviation 22z Wednesday through Monday
Short term through Thursday night ... Conditions lowering to
widespread ifr in ra and fog tonight. Llws developing tonight
through Thursday morning with surface gusts near the coast
approaching 50 kt for a brief window early Thursday morning.

Gusts up to 25 kt expected at remainder of terminal sites.

Conditions improving to MVFR from SW to NE Thursday morning in
cigs and -shra. Westerly winds gusting to 25 kt Thursday night.

Long term... MVFR brief ifr conditions will be possible at
northern terminals on Friday as clouds and showers persist on
the back side of the nor'easter. Otherwise, high pressure builds
into the region on Saturday and allows forVFR conditions at
all terminals with generally light winds through the weekend and
into Monday.

Marine
Short term through Thursday night ... A band of strong winds
with the low level jet crossing the waters late tonight and
Thursday morning with a period of storm force winds likely even
in the bays. Winds will drop off but with gales likely for much
of the remainder of the period as the system begins to pull
away.

Long term... SCA conditions will be possible Friday and Friday
night, primarily due to winds. The weekend and Monday look quiet
as high pressure dominates, but winds and seas will build to sca
criteria late Monday and remain elevated through Wednesday.

Hydrology
Widespread rainfall will move into the region tonight. Overall
looking at widespread 1.5- 2" with areas of 3-4". Highest
precipitation totals will be focused along the terrain where an
easterly low level jet will help to focus rainfall. Overall dry
antecedent conditions will substantially lower the flood threat
for both river and flash flooding, however some minor flooding
is likely.

The flashier rivers in the mountains may see minor flooding
including the saco and upper pemi. Further south, the highest
rainfall totals are expected along the hillsborough cheshire
county border in the headwaters of the contoocook and souhegan
which will also need to be monitored for minor flooding.

Across the region minor flooding of low lying areas is likely,
especially in urban areas where leaves and debris from the winds
will result in clogged drains. Localized flash flooding is possible,
however the progressive nature of the system means that threat is
more limited. Have issued a flow watch for southwest new hampshire
where models continue to advertise the highest QPF amounts
overnight and early Thursday.
