What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure will build into the region through Friday and
will hold over the area through Saturday. A coastal wave of low
pressure with an associated warm front will rapidly approach
from the south Saturday night and will lift north through the
region on Sunday. A moist tropical air mass will stream into
the region for much of the upcoming week with a likelihood of
tropical showers and thunderstorms each day through midweek.

Near term tonight
10pm update...

temperatures dropping fast in northern valleys, down into the
mid 50s already. Afternoon dewpoints were in the mid 40s, so
expect this drop to continue until the mid 40s before making a
slower fall thereafter. Have lowered forecast lows in a few
spots based on evening observations and expected clear and calm
conditions. Would not be surprised if berlin makes it into the
30s, but for now will drop them to 41. Dropped sanford, concord,
lewiston, keene all into the 40s as well. Other than watching
the temperature drop tonight, there has not been much that needs
updating from prior forecast.

8pm update...

have made minor adjustments to temperatures tonight as dry air
moves in this evening and high pressure brings good radiational
cooling. Not as concerned about fog considering the dry air
present, with even drier air just above the surface. Best source
of moisture will be near ground level with the recent rainfall
and evapotranspiration, which may be enough to bring scattered
fog to the most sheltered valleys.

Original discussion...

sfc high builds tonight beneath departing 500 mb trough. Winds
should diminish, allowing for some radiational cooling in the
sheltered locations, although light NW flow will keep up over
the hilltops and along the coast. Should see some valley fog as
well. Lows range from the mid to upper 40s in the mtns, to the
mid 50s on the coast and in SRN nh.

Short term Thursday and Thursday night
Ridging builds aloft, and should allow sfc ridge to hold over
the CWA thru Thu night, with light flow expected. Given lack of
flow, will likely see a bit of a sea breeze get going, so inland
areas will likely end up a few degrees warmer than Wednesday,
while the coast will be a few degrees cooler. So, again mainly
in the mid 70s to low 80s, but coolest at the coast. Skies will
be mostly clear as well, and with light winds may see a better
radiational cooling night Thu night, but with warmer air in
place will likely cancel things out a bit, and temps Thu night
will be similar to Wed night, the only difference may be more
variation on smaller scales.

Long term Friday through Wednesday
High pres over the region Friday will move offshore Sat allowing
a moist south to southeast flow to develop with a return to
increasing dewpoints. Skies will remain mostly clear into
Saturday. Models in very good agreement on the strong digging
upper low into the ohio valley picking up a significant piece of
energy over the southeast u.S. And rotating it northward with a
strong negative tilt and deepening surface low along the mid
atlantic coast. Models move this system rapidly north and by
early Sunday the system will be rapidly approaching the area.

Conditions will deteriorate rapidly early Sunday from south to
north. Tropical showers and thunderstorms will rapidly spread
north across the forecast area Sunday, and considering the
source region and bermuda high setting up to the east, high
pwats a certainty so QPF amounts could be significant. Also
there is the potential for a significant wind field to develop
on the east side of this system Sunday due to significant
forward speed to the north combined with the strong gradient
wind off the euro model, which is preferred. After the first
short wave exits to the north, going forward for early to
midweek a classic wet tropical pattern sets up across the
northeast as the upper low remains quasi stationary to the west
over the ohio valley while the large bermuda high builds slowly
west and north. This will allow several shortwaves to move
around the periphery of bermuda high with tropical moisture in
place. Basically this all spells warm and very muggy conditions
early to at least midweek with daily tropical diurnal nocturnal
showers and thunderstorms. Confidence high on this potential
heavy rainfall setup that will last for several days.

Aviation 00z Thursday through Monday
Short term... MainlyVFR. Valley fog possible at khie kleb
tonight and Thu night.

Long term...VFR through Saturday. Thereafter, a tropical air
mass will provide MVFR ifr conditions in showers and areas of
fog Sunday through midweek.

Marine
Short term... No flags.

Long term... SCA conditions will possibly develop late in the
weekend and last through midweek. Depending on the track of the
wave of low pressure winds over the outer waters may approach
gales late Sunday into early next week. A prolonged south to
southeast fetch will allow seas to continue to build and remain
high through the week.
