.SYNOPSIS...
Low pressure south of New England drifts east today with high
surf gradually diminishing today. A cold front crosses
Wednesday morning with gusty northwest winds ushering a colder
airmass through Thursday. High pressure settles south of New
England late this week for a warming trend over the weekend.
The next chance for rain arrives around Sunday as a frontal
system approaches from the west.
&&
.NEAR TERM /TODAY/... Less breezy and warmer today as stacked
low pressure off the Mid- Atlantic coast continues to pivot out
to sea. This will reduce the moisture footprint overhead that
has been supporting showers this morning.
Coverage of showers will continue to decrease as the morning
goes on. A shortwave this afternoon may bring an additional
round of showers to the interior and mountains, but is expected
to be light.
Wave heights and period along the coast continue to support High
Surf Advisory criteria today. While wave heights will be less
than Monday and decreasing through the day, the high surf can
still provide dangerous rip current conditions and beach
erosion. An extension or Rip Current Statement may be needed
into Wed morning as the long period swell remains.
&&
.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...
Dry tonight as high pressure pushes into the Great Lakes. Winds
become NW, and this will keep overnight lows cool in the lower
40s with mid 30s in the mountains. Some uncertainty on cloud
conditions overnight, but increased low level winds will prevent
full decoupling and good radiational cooling conditions.
Northerly flow continues during the day Wednesday. Cooling with
height should promote more daytime cloud development. Some
guidance develops shower chances for the area, but currently
think this will be light, or offshore as greater instability
resides there.
It will be a noticeably cooler day in the mountains and
foothills as temps top out in the upper 40s to around 50. For
the rest of the interior and coast, highs push into the upper
50s and lower 60s. Temps will feel a couple degrees cooler as
winds gust around 25 mph through the afternoon.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
Gusty northwest winds will continue through Thursday as there
will be a tight gradient between high pressure to the west and
low pressure east of the Canadian Maritimes. Highs on Thursday
will range from the 40s across the north to mid 50s south with
peak gusts around 25 to 30 mph. Elevated winds will limit the
potential for radiational cooling Thursday night while it will
still be seasonably cold with lows in the mid 20s north to mid
30s south.
High pressure builds closer to overhead Friday before sinking
southward. There will still be enough of a gradient for breezy
NNW winds, but will not be as gusty as Wednesday/Thursday. High
pressure will promote fair skies with highs in 50s to low 60s.
Southwest flow deepens on Saturday allowing temperatures to
climb into 60s. A frontal system approaches from the Great Lakes
Sunday with temperatures climbing into the 60s to low 70s. The
latest round of NWP guidance suggest Sunday will stay mostly dry
with rain becoming likely Sunday night into Monday.
&&
.AVIATION /04Z TUESDAY THROUGH SATURDAY/...
Short Term...MVFR ceilings early this morning for southern NH
terminals. The trend will be towards VFR as low deck erodes
south on north winds. SHRA will have also decreased through the
morning. A weak wave will provide some scattered showers this
afternoon as well as a NW wind shift. Stronger cold front
arrives Wednesday as NW gusts increase to around 25 kt for much
of the area.
Long Term...Mainly VFR Wednesday night through Saturday. NW
winds will gust to 25 kts Thursday and will diminish Thursday
night and Friday
&&
.MARINE...
Short Term...Just a few gusts to Gale remaining early this
morning. Winds will continue to slacken through the first half
of the day, but wave heights and period decrease much slower.
While the SCA was extended through Wednesday, further extension
will likely be needed outside of the bays and harbors. A cold
front crosses the waters Wednesday, again bringing a period of
gusty NW winds.
Long Term...NW winds and elevated seas will likely require a SCA
Wednesday night into Friday morning. Some gusts could approach
Gale Force along the outer waters during the day Thursday. Winds
shift out of the SW Saturday as high pressure settles south of
the waters.
