Synopsis
The pattern of scattered thunderstorms in the afternoon and
evening will continue through Sunday. High pressure in the
atlantic will direct a moist flow into the forecast area through
much of next week. Weak troughing will linger locally. The
pattern supports a chance of mainly afternoon and evening
thunderstorms. Temperatures will be a little above normal.

Near term through tonight
Stratus has developed near the coast and pushed into the
midlands and csra. Expect mostly cloudy skies and reduced
visibilities across much of the central and eastern forecast
area this morning, scattering out by late morning.

The synoptic setup for today will be similar to the previous day
with a sharp moisture gradient over the area and weak upper-
level troughing. This will support scattered convection during
the afternoon lingering into the evening. Convection allowing
models (cams) suggest higher convective coverage in the coastal
plain and the higher terrain of the upstate. Though outflow
boundary interactions should shift the focus in late
afternoon evening to development into the midlands and csra.

Weak forcing and weak to moderate instability will limit the
potential for severe weather. There may be a few isolated storms
which are able to produce strong downburst winds given the mid-
level dry air high dcape values across much of the fa. Expect
highs generally in the low to mid 90s with overnight lows in
the low to mid 70s.

Short term Sunday through Monday night
Surface high pressure in the atlantic will direct a weak
southerly flow into the forecast area. The models indicate a
weakness in h5 ridging over the region. The pattern supports
continued hot conditions with a chance of mainly afternoon and
evening thunderstorms. Followed the guidance consensus with
highs mainly in the middle 90s. Expect peak heat index value 100
to 105 and below advisory criteria. The guidance consensus
supports pops 20 to 40 percent with the greater values in the
southeast section closer to deeper moisture.

Long term Tuesday through Friday
The GFS and ECMWF indicate little change in the overall pattern
during the medium-range period. We should continue to be on the
western side of the bermuda high. A weakness at mid levels between
the atlantic and the southern plains ridge is forecast to continue.

The pattern supports slightly above normal temperatures with
scattered mainly afternoon and evening thunderstorms. Any severe
thunderstorm threat will be strictly pulse-induced as the
atmosphere will be devoid of any substantial shear.

Aviation 12z Saturday through Wednesday
This morning, stratus has developed near the coast and is
impacting or expected to impact all TAF sites. Ifr lifr ceiling
restrictions will continue through the early morning. The
stratus will scatter out through mid to late morning.

The weak surface boundary will remain over the area today.

Winds will be light and variable through the remainder of the
period. Scattered thunderstorms will develop in the afternoon,
with higher coverage to the east coinciding with the deeper
moisture. Though outflow boundary interactions may shift the
focus of development into the midlands and csra in the late
afternoon or evening. Confidence in vcts is highest at ogb,
which is nearer the deeper moisture, but given the scattered
nature of the storms confidence is low at the other TAF sites.

Overnight, we expect another round of stratus to develop near
the coast and push inland bringing ifr lifr ceiling restrictions.

Patchy fog may also develop with drier air aloft and abundant
low-level moisture. The cira simulated satellite data, which
has performed well the past few nights, indicates the potential
for restrictions at all TAF sites near sunrise.

Extended aviation outlook... Seasonal conditions are expected
with periods of restrictions in the early morning from low
stratus or fog. Then additional restrictions possible in the
afternoon and evening from widely scattered convection. Though
vfr should be the dominating rules at the terminals.

Cae watches warnings advisories
Ga... None.

Sc... None.
