.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 /THROUGH TONIGHT/...
As of 135 PM Monday...

Post-frontal dry air continues to spill south into central NC this
afternoon as dew points are currently hovering in the lower to mid
50s (N) to lower 60s (S). Temperatures are currently hovering in the
upper 70s/lower 80s, and shouldn`t increase too much more today.
Expect some residual gusts to persist the next few hours, but sfc
winds should subside through sunset.

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 135 PM Monday..

Surface high centered over the New York region will stretch into NC
from the north bringing a short relief from the heat. Light
northerly flow will result in temps ranging in the low to mid 80s
for much of the area. It will feel comfortable outside as dew points
will stay in the 50s during the day. By Tuesday evening the surface
high will shift offshore and the surface flow over central NC will
become more south/southeasterly. Tuesday night will be dry and clear
with lows ranging in from the low to mid 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 /17Z MONDAY THROUGH FRIDAY/...
As of 1245 PM Monday...

VFR conditions will prevail through the 24 hour TAF period as dry
air filters in behind a departing cold front. Some residual VFR
stratocu may stick around some this afternoon, but overall skies
should be mostly clear.  Residual gusty nely sfc flow early this
afternoon will subside through later this afternoon and into the
evening. Light nly flow early Tuesday will turn more ely but remain
light in the afternoon.

Outlook: VFR conditions will continue Tuesday 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 and early morning fog/stratus next weekend.
