Synopsis
Atlantic high pressure and an inland trough will prevail until
late week when a cold front possibly affects the area.

Near term until 6 am Tuesday morning
This evening and tonight: scattered to numerous showers and
thunderstorms will continue until the loss of diurnal heating.

Overall, the near storm environment remains unimpressive with
meager lapse rates, low dcape values, and an overall lack of
strong surface destabilization. Storm motion remains to the
north around 10 mph, which should preclude much in the way of a
heavy rainfall threat. The weak surface low that is helping to
provide a deep feed of moisture into the forecast area continues
to sit over south-central georgia. This feature is expected to
slowly meander to the north overnight and should help to
maintain at least scattered showers and thunderstorms near its
center through the night. Some of this activity could clip the
inland portion of the forecast area including tattnall, candler,
bulloch, and jenkins counties. Held on to 20-30 percent rain
chances in this area through the overnight with a dry forecast
elsewhere. Lows should be a persistence forecast, with low to
mid 70s in most locations.

Short term 6 am Tuesday morning through Thursday
Surface high pressure will prevail offshore, while weak
troughing resides inland. Aloft, a weak low will break up the
mid level ridge centered over the western atlantic and south
central u.S. This weakness in the height fields will result in
periodic shortwave energy traversing nearby. Rain chances will
be fairly typical for summertime, generally in the 20-30% range.

Pops are highest inland in proximity to the deepest moisture
and best forcing. Widespread severe weather threat appears to be
low, but a couple stronger to marginally severe storms can't be
ruled out during peak heating.

Temperatures will be relatively seasonable for mid to late
august. Highs will be in the upper 80s low 90s, warmest on
Thursday. Lows will range from the low 70s inland to mid 70s at
the coast.

Long term Thursday night through Monday
Low to moderate confidence this period. The pattern doesn't
change much until a cold front possibly moves near or even into
the area this weekend and stalls into early next week keeping
the weather more unsettled than normal. Not expecting much more
than isolated severe storms flooding at this time. Temperatures
should fall back closer to normal given the increased rain cloud
coverage.

Aviation 20z Monday through Saturday
Earlier showers and thunderstorms passed by ksav to the west and
only isolated to scattered activity should be around the area
through the evening. Removed the tempo for thunder but did
maintain a mention of showers. At kchs, shower and thunderstorm
development has shifted inland and should stayed displaced away
from the terminal through the evening. Overnight, there could
again be stratus development, but the current expectation is
that anything that develops will remain inland of the terminals.

Extended aviation outlook: flight restrictions are possible
mainly from afternoon evening showers and thunderstorms through
late week.

Marine
Tonight: south to southwesterly flow will prevail through the
night with speeds topping out in the 10-15 knot range. Seas will
average 2- 3 feet.

Tuesday through Saturday: the marine zones will remain on the
west side of atlantic high pressure, allowing predominantly
south flow to persist. Winds speeds will average around 15 knots
or less, staying below headline criteria. Seas will be 2-3
feet.
