.SYNOPSIS...
Temperatures are expected to remain below normal through the
weekend before returning to normal later in the week. Isolated
to widely scattered showers or storms are possible this
afternoon and evening, but rain chances ramp up Sunday and into
early next week as deeper moisture returns to the Southeast.
Then, more typical summertime diurnal chances for showers and
storms arrives for mid to late week.

.NEAR TERM /THROUGH TONIGHT/...
Key Message(s):

- Scattered, light showers early this morning
- Showers likely through much of the day with isolated t-storms

An inverted trough just southeast of the South Carolina coast
and increasing moisture will allow showers to continue across
the area early this morning.

Expect daytime temperatures below normal again today with highs
around 80 degrees. Strengthening E/SE low level flow will usher
more moisture into the FA with PWAT values rising to between
2.1-2.3". As moisture increases through the day, an inverted
surface trough looks to pivot into the area from the south-
southeast along with some shortwave energy. This will allow
numerous showers to develop across the region, perhaps peaking
in the late afternoon/evening when models show the most
prominent shortwave lifting into the area. A few thunderstorms
are possible in the afternoon and evening. The overall chance of
thunderstorms is low with forecast MUCAPE values generally less
than 1000 J/kg. High PWAT values and saturated soils will set
up a heavy rain threat today. The convective precip may lead to
localized flooding if showers continually move over the same
spot. The HREF LPMM continues to show localized spots with 2-3"
rain accumulations. Showers will likely continue into the
overnight period as deep moisture convergence continues.

.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...

Key Message(s):

- Below-normal temperatures continue Monday as widespread
  showers continue

Deep onshore flow is forecast to continue on Monday as the overall
pattern continues to shift. While upper level westerly flow will be
present across the area, flow below 850 hPa is forecast to be out of
the east and southeast, albeit a bit weaker than on Sunday. PWs are
still forecast to be robust and >2" across the forecast area, with
efficient rain producers expected within the showers as they push
through the region. Thinking that most will get rain but that
coverage and duration will likely be less than it was yesterday.
This is primarily owed to the weaker flow leading to less overall
forcing. Highs are expected to be in the upper 70s and low 80s again
as copious cloud cover hangs around the forecast area. Overnight,
some showers will likely continue with lows in the lower 70s.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...

Key Message(s):

- Temperatures warm through the remainder of the week with a
  return to more seasonable shower/storm chances.

The forecast for the remainder of the period looks increasingly
normal for this time of year. Ensembles and operational models
are in good agreement, leading to high forecaster confidence in
the long term forecast. Ridging in the mid and upper levels of
the atmosphere is forecast to gradually build westward from the
Atlantic through late week. GUidance does paint the center of
the ridge to our south for much of the week, which should foster
a return to near normal afternoon temps while also seeing near
to slightly above normal chances for afternoon showers & storms.
A weak shortwave is showing up on Tuesday, which should help to
focus storm chances. Thereafter, it looks more typical of
summertime as the ridge slowly shifts west and centers over the
southern MS Valley by the end of the week. With robust low-
level moisture in place, daily chances of storms are expected
with highs in the low 90s Wed-Sat of next week. It does look
like a more concentrated chance of rain could approach on
Friday/Sat as a weak and/or weakening front pushes towards &
hangs up around the region. Overall, though, the forecast looks
very typical for August for the majority of this upcoming week.


&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Restrictions likely during much of the next 24 hours.

Showers will continue through the early morning leading to
periods of MVFR visibility restrictions. With deep moisture
pushing into the region today, stratus will move over all the
terminals leading to MVFR or possibly IFR ceilings. Numerous
showers will develop this afternoon and evening, creating
periodic restrictions in heavy rain. Isolated thunderstorms are
expected with highest likelihood of impacting OGB. Ceilings will
either be MVFR or near MVFR through the day and will likely
lower to IFR at all sites tonight. Scattered showers should
continue through the night as well. Light winds will be out of
the east for much of the TAF period.

EXTENDED AVIATION OUTLOOK...Deep moisture remains in place early
this week allowing for periods of restrictions and convection
each day. The highest rain chances will be Monday and Tuesday.
Beyond that more typical summertime conditions return.
