Synopsis
Weak high pressure will nose into the region today and into the
weekend as a low pressure moves south of the area. This high
will remain established over the northeast through early next
week with an extended period of pleasant weather. A cold front
will cross the area Thursday before stalling to our south.

Near term until 6 pm this evening
655 am update: some patchy valley fog noted in the ct river
valley otherwise mostly clear conditions over southern areas.

In the mountains and foothills mostly cloudy conditions occuring
early this morning. As high pressure builds across the area,
subsidence in the mountains will dissipate the clouds.

Eliminated any mention of fog except for over the ct river
valley through mid morning. Made minor adjustments to sky cover
based on vis IR satellite imagery. Tweaked temps based on latest
obs data.

Previous discussion:
high pressure will build across the region today allowing for
clearing skies as the day progresses. During the early morning
hours some patchy fog is expected, but will burn off by mid
morning. Temps will be pleasant reaching the mid 70s in the
mountains and upper 70s to lower 80s elsewhere. With warm temps
today but still cold ocean temps due to some upwelling over the
last few days, ocean temps have fallen back into the mid-upper
50s so a beach hazards statement should be noted.

Short term 6 pm this evening through 6 pm Saturday
High pressure over the region tonight and Sat will bring mostly
clear skies across all central and northern areas of the region
while southernmost areas will see some mid to high clouds from
the system passing to the south and east of our area. Used
blended model guidance for temps which will be a few degs below
seasonal levels for both tonight and sat.

Long term Saturday night through Thursday
Good stretch of weather coming up for the weekend and into early
next week as high pressure dominates the weather map. Longwave
troughing will set up just offshore Sunday into Monday. Models
are in unison that secondary cyclogenesis will track off the
delmarva peninsula and remain south and east of the gulf of
maine. Showers may brush the islands and coastal zones but at
this time it looks like they will stay far enough south to
remove them from the forecast.

Additional rain chances along with some thunderstorms will be
possible Tuesday into the midweek period as a frontal boundary
sags south out of canada. Temperatures in the mid to upper 70s
will give way to readings in the lower to upper 80s Wednesday
and Thursday ahead of the front with warm air advection and
compressional warming contributing to this warm up.

Aviation 12z Friday through Tuesday
Short term... Areas of fog until 12z will bring conditions to
lifr over the ct valley locations such as kleb. Most other
areas will remain free of fog early this morning. After 12z all
areas will beVFR for the rest of the day and through sat.

Long term...

expect patchy MVFR Sunday morning in fog... Especially for hie
and leb. A system approaching from the mid atlantic region on
Tuesday may result in MVFR to ifr conditions in rain and stratus
for mht... Con... Pwm... And rkd.

Marine
Short term... A light south to southwest flow today will become
west to northwest after the passage of a cold front over the
waters by this evening. A north to northeast wind will develop
later tonight and increase Saturday due to the storm system
passing to the southeast. Seas will also build over the outer
waters. Conditions may approach minimal SCA criteria by later
in the day sat.

Long term... Slow moving low pressure to our south will produce
winds just below SCA levels over the southern waters on Sunday.

Currently it looks like waves will remain below SCA levels as
well.

Gyx watches warnings advisories
Me... Beach hazards statement through this evening for mez023>028.

Nh... Beach hazards statement through this evening for nhz014.

Marine... None.
