.WHAT HAS CHANGED...
The Aviation section has been updated for the 12z TAF issuance.

&&

.KEY MESSAGES...
- 1) Above normal temperatures will continue to impact the area
  throughout the next 7 days. Humidity levels will increase
  this weekend and into next week, resulting in increasing heat
  indices across the region. Heat Advisories could be needed
  this weekend and into next week, especially from Sunday
  onward.

- 2) Typical summertime convection returns on Sunday, with
  chances increasing further into next week.

&&

.DISCUSSION...
KEY MESSAGE 1: Above normal temperatures will continue to
impact the area throughout the next 7 days. Humidity levels will
increase this weekend and into next week, resulting in
increasing heat indices across the region. Heat Advisories could
be needed this weekend and into next week, especially from
Sunday onward.

Strong ridging will persist across the region this weekend and
throughout much of next week, resulting in above normal
temperatures. Dewpoints will again be relatively low today and
Saturday, with values dipping into the mid 60s across inland
areas. Heat index values for today will generally top out around
100 degrees in most areas. However, we will see heat indices
steadily rise each day through the weekend and into next week as
subtropical high pressure starts to drive higher humidity.
Saturday heat indices will rise more into the 100-105 degree
range, with a few pockets of slightly higher values possible.
Sunday looks like the first day where a larger area of heat
indices upwards of 108-110 degrees will be possible. This will
continue through much of next week as well, and Heat Advisories
could be needed. Also, daily record high temperatures and record
high minimums could be challenged at times through the period.
See the Climate Section below for details.

KEY MESSAGE 2: Typical summertime convection returns on Sunday,
with chances increasing further into next week.

A strong ridge centered over the region will keep convection to
a minimum late week, including Independence Day, with a dry
forecast in place. The ridge will shift offshore during the
latter half of the weekend and early next week, allowing for a
more typical summertime convective pattern to develop. Isolated
to scattered showers and thunderstorms will be possible each
day, especially in the afternoon when instability is at its
peak. The threat for organized severe weather is low, but can`t
rule out a stronger storm or two each day.

&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
VFR conditions will prevail at KCHS, KJZI, and KSAV through 12z
Saturday.

Extended Aviation Outlook: Brief flight restrictions are
possible in afternoon showers/thunderstorms late this weekend
into early next week.

&&

.MARINE...
Today through tonight: Light northeast flow this morning will
gradually turn southeasterly this evening and eventually
southwesterly overnight. Wind speeds will be highest this
afternoon and evening, mainly along the land/sea interface with
the sea breeze circulation. Wind speeds of 10-15 knots and gusts
potentially as high as 20 knots can be expected during this
time along the coast. Seas should average 2-3 feet.

Saturday through Wednesday: A typical summertime pattern is
expected across the coastal waters over the weekend into next
week, with winds generally out of the southwest in the early
mornings, then switching from the south-southeast for the
afternoons. Speeds are forecast to stay below small craft
advisory criteria, however some gusts in the low 20 kt range are
possible, especially as we move into next week and the pressure
gradient tightens. Seas will average 2-4 feet.
