Area Forecast Discussion
National Weather Service Columbia SC
446 AM EDT Wed Jul 20 2022
Typical summer pattern with seasonable temperatures and mainly
diurnal showers and thunderstorms through Thursday. A front will
attempt to cross the area late Thursday bringing better chances
of widely scattered to widespread thunderstorms. Warmer and
slightly drier this weekend into early next week.
.NEAR TERM /THROUGH TONIGHT/…
Mean upper trough axis still just to our NW, with a weak surface
trough appearing to extend across the NC/SC piedmont into NE GA.
Upper energy appearing to be contributing to scattered showers
and thunderstorms approaching the CSRA early this morning. Upper
trough to slowly traverse the region today, with main upper
energy moving across our N/NE FA early today and into the
eastern Carolinas this afternoon. A weak upper disturbance
behind it to move through late today and this evening. Diurnal
heating and a moist atmosphere expected to promote scattered
showers and thunderstorms. Latest CAMs appear a little more
consistent than the last couple of days and indicate good
convective coverage across the region this afternoon into this
evening. Model consensus generally indicates good chance POPs,
with near normal temps.
.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/…
Aloft, a trough axis will be rotating into the region on
Thursday. At the surface, a weak cold front will be approaching
the region during the day, but is not expected to make it into
the forecast area. However, a lee-side trough will set up
across the area ahead of the front during the day. Temperatures
continue to be very Summerlike, with highs in the afternoon
expected to climb into the low to middle 90s. Plenty of
moisture will also be spread across the cwa, with pwat values
peaking out between 2.25 and 2.5 inches during the afternoon.
Thunderstorms are expected to develop during the early afternoon
ahead of the cold front, and even along the lee trough.
Scattered convection will continue into the evening as the more
organized convection that develops along the front pushes
southward into the cwa. Winds through the low and mid levels do
show some turning of the wind, with speeds mainly up to 30
knots. Weaker winds in the upper levels. Main threats will be
heavy rainfall due to the high moisture content, and strong down
drafts causing damaging winds due to precip loading. Activity
should diminish late Thursday evening. Warm conditions persist
Thursday night, with lows in the middle 70s.
On Friday, the upper trough weakens and the pattern aloft
begins to flatten out as ridging begins to slowly build back in.
The surface front north of the area will weaken, but with high
pwat values still over the region, we should still see
scattered showers and storms during the afternoon along
lingering surface boundaries and the sea-breeze. Convection
diminishes after sunset. Temperatures continue near normal.
.LONG TERM /SATURDAY THROUGH TUESDAY/…
Into the weekend, upper ridge strengthens across the area, while
the main storm path retreats further north. High temperatures
will climb into the mid to upper 90s into Monday. Can not rule
out isolated convection during the afternoon/evening each day
through the period.
.AVIATION /09Z WEDNESDAY THROUGH SUNDAY/…
Scattered thunderstorms to the N and NW of DNL/AGS moving to
the ESE and may affect DNL/AGS in the near term.
Otherwise, areas of stratus with MVFR to IFR CIGs appear will
affect our TAF sites early this morning, based on latest
satellite loops and surface obs.
An upper trough, diurnal heating, and a moist atmosphere
expected to result in additional scattered thunderstorms this
afternoon and evening. For now, will indicate VCTS. May upgrade
to TEMPO TSRA in later TAF issuances.
EXTENDED AVIATION OUTLOOK…Scattered mainly afternoon and evening
thunderstorms Thursday, and possibly again Friday but favoring
southern areas, along with some possibility of patchy late
night/early morning fog/stratus. Less diurnal thunderstorm coverage
expected Sat/Sun, with low chances of late night/early morning
