area forecast discussion... Updated
national weather service gray me
852 am edt Fri aug 23 2019

Synopsis
High pressure will dominate the weather pattern this weekend for
pleasant weather and comfortable humidity levels. An area of
low pressure off the east coast will track south off CAPE cod
early next week that will likely be too far offshore to impact
the area. A front will approach the area from the west midweek
bringing an increase in temperatures and humidity and a chance
for precipitation.

Near term until 6 pm this evening
845 am: quick update for sky cover trends and to adjust
temperatures upward a bit through the day given t8 from the gyx
12z RAOB showing t8s between 10 and 11c which should allow a
few sites in the downslope regime south of the mountains to
reach 80s. Significantly drier airmass today with dewpoints
largely in the 50s and rhs falling to around 40 percent this
afternoon.

600 am... Minor estf update to reflect the current mesonet and
satellite trends in near term grids.

Prev disc...

at 06z... A 1000 millibar low over quebec with a trailing cold
front through the gulf of maine and a series of weak surface
troughs over quebec. A sprawling 1024 millibar high was centered
over western ontario province. An upper low was evident in goes
water vapor imagery over quebec. While the cold front has slid
offshore... Southern new hampshire as well as the coastal plain
remain under the western and northern periphery of the its cloud
shield. An impulse pivoting around the upper low is backing the
flow a bit this morning and a few light showers may brush
seacoast new hampshire through dawn. Otherwise... A quiet start
to the day with northern areas seeing some early morning valley
stratus and fog. The front will retreat further offshore by
later this morning with partly to mostly sunny skies expected
for the balance of the day. Highs will range from the upper 60s
to near 70 for the mountains... With 70s elsewhere.

Short term 6 pm this evening through 6 pm Saturday
For tonight... The upper low over quebec may spill a few clouds
into northern and eastern sections of the forecast area.

Otherwise it'll be a mainly clear and cool night with light
winds and the dry airmass allowing temperatures to drop into the
40s across the mountains with lower and mid 50s elsewhere. I
expect some patchy valley stratus and fog to form once again
towards morning. On Saturday... The high center builds by to our
north with northerly flow turning onshore during the afternoon
hours. We'll average partly sunny as some fair weather clouds
bubble up with daytime heating. The day will have a fall-like
feel with high temperatures ranging from the upper 60s to mid
70s.

Long term Saturday night through Thursday
Fair weather is expected for most of the long term period as new
england gets entrenched into a semi-rex block pattern with weak
upper low pressure overhead into early next week and high
pressure at the sfc. Other than some clouds from time to time
with the cooler air aloft, our weather will remain dry through
Monday with temperatures near to slightly below normal.

Radiational cooling is likely to occur for several nights with
the sfc high pressure ridging remaining in place . Have therefore
preferred MOS guidance here. Have also added valley fog to the
interior as a result of the expected raditational cooling.

Thereafter, a short wave trough is expected to approach from the
west by Tuesday night. This is conjunction with the moisture
associated with offshore low pressure should allow chances for
showers to increase in the Tuesday night through Thursday
timeframe. However, confidence is low on placement of forcing
for ascent by midweek due to divergence in model solutions.

Therefore, will continue with low chance pops.

Aviation 13z Friday through Tuesday
Short term through Saturday ... LCL ifr in valley status and fog
btw 08z and 12z Fri and again 08 to 12z sat... OtwVFR expected.

Long term... Saturday night through Monday will feature high
pressure with light winds.VFR conditions are expected outside
of the usual nighttime valley fog this time of year.

Marine
Short term through Saturday ... Winds and seas will remain below
sca threshold as high pressure gradually builds by to our
north.

Long term... Conditions are expected to remain below sca
thresholds through Monday. There is a chance that winds and seas
on the outer waters build to SCA levels late Tuesday through
Wednesday as offshore low pressure moves by to the southeast.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.
