Area Forecast Discussion
National Weather Service Raleigh NC
1027 AM EDT Mon Jul 1 2024

.SYNOPSIS...

Much drier and cooler high pressure will then extend into the
southeast today through Tuesday. A gradual return of heat and
humidity is expected by the end of the week.

&&

.NEAR TERM /TODAY THROUGH TONIGHT/...
As of 1027 AM Monday...

The sfc cold front has just passed through the southern edge of our
CWA.  Post-frontal nely gustiness has been impressive along and east
of the US-1 cooridor (KRDU gusted to 29 kts, KRWI to 31 kts, KFAY
just gusted to 42 kts!). Expect this gustiness to gradually subside
through mid afternoon, but could see some additional higher gusts
for this time of year in these locations the next few hours.

Otherwise, a few lingering light showers remain in the far
northeast, but overall the rain has laregely moved out of our area.
Dew points are quickly crashing into the mid 50s across the north,
as dry air spills in behind the front. Expect a cooler and drier
rest of today, with highs only reaching the upper 70s to lower 80s
and PWAT dropping well below normal this afternoon.

A pleasant night is on tap with lows in the upper 50s to lower 60s
and dew points in the 50s under mostly clear skies.

&&

.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
As of 235 AM Monday...

The high pressure will be located along the eastern seaboard on
Tuesday and Tuesday night. Sunny skies with low relative humidities
can be expected with highs in the lower to mid 80s. Clear and
relatively cool conditions are expected Tuesday night with lows in
the mid 50s to lower 60s.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
As of 250 AM Monday...

Aloft, the mid-level anticyclone will sit over the TN Valley/Deep
South Wed/Wed night. A series of northern stream s/w disturbances
will track eastward from the northern Plains through the Great
Lakes/OH Valley from Tue through Sun, with each successive s/w
slowly pushing the high, first southward to over the Southeast and
Deep South Thu and Fri then eastward off the Southeast US and mid-
Atlantic coast Sat and Sun. At the surface, the high will sit off
the mid-Atlantic coast Wed/Wed night, with the ridge axis shifting
eastward out of central NC through early Thu. Once the ridge shifts
east out of the area, a lee trough will set up and remain in place
through Sat night, when a cold front will approach from the west. As
of the latest model solutions, the front appears to wash out along
or west of the Appalachians. Expect swly flow and the advection of
warm, moist air into the area to take over once the ridge moves out
Thu morning. Temperatures may actually be near normal on Wed, but
will then be above to well above normal Thu through Sun. As for
rainfall, Wed/Wed night should be dry, but as the mid-level ridge
gradually gets suppressed south and the lee trough strengthens, some
diurnally driven convection will be possible Thu, but more likely
Fri, Sat, and Sun aft/eve. Latest forecast heat index values do
creep back to around 105 again in a few spots on Thu, however the
more widespread heat index values of 105 to 109 (across much of
central NC) are expected Fri and Sat. Some lingering heat index
values of 100-105 are possible across the south and east on Sun.

&&

.AVIATION /12Z MONDAY THROUGH FRIDAY/...
As of 645 AM Monday...

Scattered showers and isolated storms will continue across central
NC early this morning as a cold front moves through between 12z and
14z. The best chance at the eastern terminals (RDU, FAY and RWI).
Some stratus is also expected to develop after about 07z-08z at FAY
and RWI, with MVFR or IFR ceilings possible.  Winds will shift to the
NE behind the cold front. NE winds may gust to 15-25 kts into
early afternoon before gradually diminishing.

Outlook: VFR conditions will continue Monday afternoon through
Thursday as dry high pressure extends down into central NC. Return
flow on Friday will promote increasing humidity and the chance for
diurnal showers/ storms and early morning fog/stratus from Friday
into next weekend.
