Synopsis
Cooler, drier air remains in place across northern new england
today as canadian high pressure slowly moves across the area.

This high will slowly move to the northeast over the next few
days, with the next low pressure system arriving Tuesday night
into Wednesday. This will bring a good chance of rain to the
area before a cold front sweeps through on Wednesday. Cooler and
drier air moves in behind this front for the end of the week.

Near term today
This morning fog will continue to form in the valleys from N to
s. Fog should lift pretty quickly after sunrise.

Surface high pressure continues to build in while aloft the
region trends more towards a dirty ridge. In the near term
today... Continued drying and clearing of clouds is expected
along with a good NE breeze. Temps will be warm and more
importantly dewpoints will be comfortable. Get out an enjoy it.

Short term tonight and Monday
Weak S WV trofing attempts to undercut the ridge aloft tonight.

At this time the bulk of the moisture looks to be well
aloft... And should result in mainly an increase in mid to high
level clouds vs. Any precip. Will have to keep an eye on it
however... As the extended range of the hrrr did develop a few
showers near the coast this evening. Given the expected high
level cloudiness... That could hamper radiational cooling
tonight. More confident in the cooler temps in the NRN valleys
than s... And so that is where I have readings near 50 and areas
of fog once again. It will still be very comfortable overnight
temps S of the mtns... With widespread 50s. Another comfortable
day expected mon... With widespread 70s and dewpoints in the 50s.

Long term Monday night through Saturday
We are beginning to see the signs of fall approaching. The
subtropical ridges are getting a bit weaker and cold air is
building over the arctic once again. There is still plenty of
warm and humid air over the southern half of north america, but
we won't be getting in on this nearly as much this week as we
have in prior weeks. A slow moving upper trough crosses the
central part of the united states during the first part of this
week, passing through new england on Wednesday. This will send
one brief shot of humid air and rain chances into new england
before the trough passes through and brings a drier air mass in
for the last half of the week. The subtropical ridge over the
southwest will flatten out and bring broadly zonal flow in the
wake of the exiting trough, which should keep temperatures near
or slightly above normal but with less humidity.

Although the center of the larger scale synoptic high will be
well off to the east of labrador, a ridge axis will remain
stretched southwestward across northern new england Monday night
bringing a clear and calm night. This should spell some good
radiational cooling conditions with temperatures dropping down
into the low 50s for many inland areas. The valleys should see
their typical late summer early fall morning fog. Winds become
more southerly during the day Tuesday with temperatures topping
out in the 70s, coolest near the coast. Will see increasing
clouds as the day GOES on with the trough approaching from the
west.

Slow moving upper trough finally makes its way into our area
Tuesday night into Wednesday, with a low level warm front trying
to lift northward into new england ahead of it, but with the
cold front moving in quickly behind. This brings just a narrow
shot of warm, humid air to work with, but it should be enough to
warrant some rain showers beginning Tuesday night and spreading
across the area on Wednesday. With the front crossing through
during the day on Wednesday, we may see another round of showers
and thunderstorms forming along and ahead of the front.

Instability will be dependent on whether or not that warm front
is able to lift north and get us into the warm sector before the
cold front arrives. If it does so, there is plenty of low and
mid level wind shear to work with to create some stronger
thunderstorms. Models are not sure yet whether or not we get
into that instability, so for now will just include a chance of
thunderstorms in the forecast.

Cooler and much drier air rushes in behind the cold front
Wednesday night. In fact, we should see fairly widespread
dewpoints in the 40s Thursday afternoon, with perhaps even a
few upper 30s. Surface high pressure slides east out of the ohio
valley and crests over new england on Friday. This keeps a
westerly flow over the region keeping things dry and slightly
warmer than normal into the weekend.

Aviation 07z Sunday through Thursday
Short term...VFR conditions expected to prevail for much of the
period... Though high pressure overhead will support valley fg at
night. Lifr conditions are expected this morning and again
tonight at hie. Less confidence at leb this morning... Where
cloud cover is keeping temps warmer. More likely they see fg
tonight. Confidence is even lower at other valley taf
sites... But a period of ifr or lower conditions is
possible... Especially tonight.

Long term... Light winds and a clear sky will lead to widespread
valley fog Monday night into Tuesday morning. This will likely
affect whitefield, lebanon, and concord. Expect increasing
clouds and lowering ceilings from west to east Tuesday evening
as a warm front approaches the area. Should see rain showers
beginning Tuesday night and lasting into Wednesday when there
could be some thunderstorms ahead of a cold front. Conditions
improve toVFR behind the cold front Wednesday evening.

Marine
Short term... Ne flow continues over the waters thru mon.

Generally expected to remain below SCA thresholds... Though some
gusts may approach 25 kts this afternoon in a small area of the
waters E of isles of shoals. Likewise... Seas may build towards 5
ft in that same area... Though not a large enough section of the
zone for a SCA at this time.

Long term... Southerly flow increases ahead of an approaching
frontal system on Wednesday. Wind gusts could approach advisory
levels during this time. High pressure builds in behind the
front for the rest of the week.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.
