1258 AM EDT SUN JUL 31 2016
Bermuda high pressure offshore with a trough inland will persist
through the weekend. A weak boundary will stall over the area this
morning and then lift back north by later tonight. A weak cool
front will approach from the northwest early next week then stall
near the area by mid week.
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
As of 1255 AM Sunday, coverage of precipitation has diminished and
the threat of thunder has waned so will keep only a slight chance
of showers in the forecast overnight as radar indicates a few
dissipating showers in eastern NC. Temperatures will fall little
overnight with morning lows expected between 75 and 80 degrees for
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/...
As of 315 PM Saturday, The weather on Sunday will continue to be
influenced from by a surface trough inland with weak shortwave
energy moving through at the mid- levels. Carried a 40 to 50 PoP
across the area for showers and thunderstorms that again could
produce heavy downpours and gusty winds. It will be another hot
and humid day with highs in the low to mid 90s inland and just a
bit cooler along the immediate coast. Heat index values could
again flirt with 105. This will largely be dependent on cloud
cover and coverage of showers and thunderstorms. Did not have
enough confidence to raise a heat advisory at this point but can`t
rule out the need for tomorrow afternoon.
.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
As of 330 PM Saturday...Unsettled through mid week as the
mid/upper ridge breaks down and transitions to a broad trough.
High pressure builds in late week.
Sunday night into Monday...Mid/Upper level ridge continues to
break down as the broad trough over the Tennessee Valley continues
to dig south. Meanwhile, the frontal boundary slowly sinks down
from the NW, but remains to the north for most of the day. This
will provide better chances for showers and thunderstorms to
develop, especially during the afternoon and evening. Expect highs
in the low 90s inland to mid/upper 80s along the OBX.
Monday night through Wednesday...The broad trough axis will be over
NC and the slow moving cold front will finally sink down into the
forecast area late Monday night. The front will be over eastern NC
Tuesday and finally push all the way on Tuesday night. The
frontal boundary will linger along the southern coastal area
Wednesday. Good coverage of convective activity expected ahead of
front, with likely POPS all of area Monday, eastern half Monday
night and southeast third Tuesday. Some locally heavy rain
possible with PW values around 2 inches, and isolated severe
possible with decent surface and mid level forcing. Did indicate
slightly slower frontal push into area on Tuesday, and lowered
POPs on Wednesday.
Not a major cool air push behind front and temps will actually just
drop back to near normal levels with highs near 90 and lows 70-75.
Thursday through Saturday...There remains some models
differences, but will keep previous forecast as the frontal
boundary remains stalled to the south of the area and dissipate
late Thursday/Friday as high pressure builds into the area from
the New England area.
Temps still near normal both days with lows 70-75 and highs near 90.
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Short term /Through 06z Monday /...

overnight. With light to calm winds and saturated low levels,
tempting to add fog for early this morning, but none has been
observed the past several morning and will follow persistence for
now. Expect showers and thunderstorms to increase again Sunday
with heating and could see some brief sub VFR if these cross a
Long Term /Sunday Night through Thursday/
