.WHAT HAS CHANGED...

The aviation section was updated to reflect the 00z TAFs.

&&

.KEY MESSAGES...
- 1) Dangerous heat and humidity will impact southeast Georgia
  and southeast South Carolina today. Extreme Heat Warnings and
  Heat Advisories are in effect for portions of the forecast
  area.

- 2) Isolated to scattered thunderstorms are expected to develop
  across southeast Georgia and up along the southeast South
  Carolina coast this afternoon and evening. There will be a
  risk of a few strong to severe storms capable of producing
  damaging wind gusts, primarily along and south of Interstate
  16.

&&

.DISCUSSION...
KEY MESSAGE 1: Dangerous heat and humidity will impact
southeast Georgia and southeast South Carolina today. Extreme
Heat Warnings and Heat Advisories are in effect for portions of
the forecast area.

While there is some weak troughing overhead, the region remains on
the eastern periphery of a strong ridge aloft with a weak front
lingering across the forecast area. As the warm and moist air
remains parked across the region, temperatures are expected to reach
up into the mid 90s to lower 100s, warmest along/south of the front.
For the same area, dewpoints will surge up into the mid to upper
70s, yielding heat index values in the 110-115 range east of I-95
and 105-110 just inland of I-95. An Extreme Heat Warning has been
issued for areas east of I-95 and south of Beaufort County, SC, with
a Heat Advisory in effect north of Beaufort and just west of I-95.
For areas north of the front, inland portions of southeast South
Carolina and southeast Georgia, heat index values will top out
around 103 this afternoon.

While the front remains near the region into the weekend, heat and
humidity will drop to near normal values.

KEY MESSAGE 2: Isolated to scattered thunderstorms are expected
to develop across southeast Georgia and up along the southeast
South Carolina coast this afternoon and evening. There will be a
risk of a few strong to severe storms capable of producing
damaging wind gusts, primarily along and south of Interstate 16.

A front is expected to gradually push southward today as weak
troughing overhead continues, becoming aligned across portions of
southeast GA and up along the southeast SC coast by the afternoon
and evening. Along and south of the front, scattered thunderstorms
are expected to develop, with the 12Z HREF and REFS indicating
probabilities have expanded northwards while remaining south of the
I-16 corridor, formerly thinking they would remain largely south of
the Altamaha River Valley. The environment in this area is progged
to have MLCAPE values upwards of 2,000 J/kg and DCAPE values of
1,000 J/kg or higher, with low-level lapse rates approaching 7 deg
C/km. While an isolated risk for hail can`t be ruled out, the
greatest risk will be for strong-damaging wind gusts, with mid-level
flow of around 25-30 knots keeping storms moving thus limiting the
heavy rainfall risk. Highest values are found along/south of the
Altamaha River Valley, where SPC maintains their slight risk (level
2 out of 5) for severe weather, though portions of the region
along/south of the I-16 corridor continues to show a marginal risk
(level 1 out of 5). The main time period of concern is roughly from
4-10pm.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
00Z TAFs - Mostly VFR conditions will prevail across the area
this evening and into the overnight. A couple isolated showers
associated with a weak front have developed along the SC/GA
boarder but impacts to aviation will be minimal if any as these
storms slowly diminish. Winds will turn northwesterly overnight
and persist into the early afternoon tomorrow. A late afternoon
seabreeze could bring light southerly winds to JZI and SAV by 19
to 20Z tomorrow.

Extended Aviation Outlook: Primarily VFR, with lesser coverage
of showers and thunderstorms Thursday and Friday.

&&

.MARINE...
Through tonight: West winds this morning will turn more
southwest and even southerly through the evening. Wind speeds
should mostly top out in the 10-15 knot range with gusts up to
around 20 knots. Late tonight, A wind shift will work across the
waters, turning winds more northerly or even northeasterly by
sunrise Thursday. Seas will average 2-4 feet today, followed by
2-3 feet overnight.

Thursday through Monday: Southeasterly flow will dominate
across the marine waters through the weekend, with gusts topping
out around 10 to 15 knots through Friday. Gusts are forecast to
shift to the SW and increase to 15 to 20 knots early this
weekend ahead of the arrival of a cold front. The cold front is
forecast to push through the region on Sunday, bringing an
additional surge in winds and seas. Small Craft Advisories could
be needed for portions of the marine waters for 25 knot wind
gusts Sunday into Monday.
