715 AM EDT SUN JUN 26 2016
High pressure will remain centered along the mid Atlantic coast
today and tonight, and will slide off the coast on Monday. A cold
front approaches from the west Monday night and will be slow to
move across the region Tuesday and Tuesday night.
.NEAR TERM /THROUGH TONIGHT/...
Current analysis indicating ~1025 mb sfc high pressure centered
along the New England coast, ridging SW into the mid-Atlantic. Aloft,
a ridge of high pressure is situated acrs the lower MS valley with
a ridge axis extending NNE to the eastern Great Lakes. Quiet
conditions prevail over the local area under mainly clear skies.
Relatively cool for late June with temperatures ranging from the
upper 50s to the mid 60s. Patchy fog has developed over the
interior but should only have a minimal impact and will dissipate
by around 12Z.
A nice day on tap with dry conditions and mainly sunny skies
(partly sunny acrs portions of ne NC). Dew pts will avg in the 50s
to lower 60s with highs to range from the mid 80s along and west
of I-95 to 75-80 F closer to the coast due to onshore E-NE flow.
Mostly clear tonight with lows in the upper 50s to mid 60s once
.SHORT TERM /MONDAY THROUGH TUESDAY/...
The high moves offshore Monday resulting in a warmer southerly low
level flow, although with the winds backed to more of a SE
direction closer to the coast. Good model consensus with respect to
trending a little slower with the arrival of increasing moisture
from the W. The main impact to the forecast will be to delay POPS
until after 21Z except over the far western zones, with little
chance for anything over far SE VA and ne NC until after 00Z.
Highs in the mid to upper 80s west of the bay...upper 70s to lwr-
mid 80s along the coast.
Models generally agree in increasing moisture across the area Monday
night as the front approaches from the west. The upper support and
jet axis remain well N/NW of the area, and the chance for severe
TSTMS will be low (SPC day 2 outlook has only marginal risk over
far NW CWA). Enough lift noted for likely pops from about I-95 on
west with chc pops to the east. Thunder chc greatest during the
evening hours. Warmer with lows in the upper 60s to lwr 70s. Not a
Models show the boundary will be slow to push across the region
Tuesday as the upper trough and associated cold front slowly moves
east. Will maintain high chc pops for now, with a period of likely
POPS Tue aftn/early evening over the SE closest to the front. Highs
in the low to mid 80s.
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Sfc cold front will be slow to push off the coast Tue ngt/Wed
mrng as upper lvl trough crosses the rgn. POPs lwrg only
gradually NW-SE into Wed aftn. Sfc hi pres crosses the FA Wed ngt

.AVIATION /11Z SUNDAY THROUGH THURSDAY/...
High pressure settles right over the Mid Atlc region today into
tngt, then slides farther e into the Atlc during Mon as a cold
front approaches fm the wnw. Expect mainly SKC at the taf sites
today into tngt, with at least MVFR or IFR fog possible early Mon

be a chance for showers and thunderstorms beginning late Mon and
continuing into Wed. The best chances for precipitation will be
through Tue night
No headlines in the short term today thru Mon ngt. High pressure
will remain cntrd just off the New England and nrn Mid Atlc cst
