.SHORT TERM /Tonight through Wednesday Night/...

Isolated showers and thunderstorms are developing across portions
of west and central Georgia this afternoon. Low level southerly
flow will continue to provide ample moisture for isolated to
scattered showers and thunderstorms across the area aided by a lee
side trough building down the Appalachians and afternoon heating.
Widespread severe storms are not anticipated, however cannot rule
out a stray severe thunderstorms with gusty winds the main threat.
The treat for thunderstorms and showers will diminish after 8 pm
with the loss of daytime heating. The moist summertime pattern
will remain across the tomorrow with scattered showers and
thunderstorms expected to redevelop with daytime heating once
again. Temperatures will continue above normal through the period
with central areas once again flirting with heat indices in the
100-104 range.

.LONG TERM /Thursday through Tuesday/...

The Gulf remains open through the long term period as the Bermuda
High stays stagnant and unwavering just off the Carolina coast, with
a surface ridge axis building through the southern Gulf states. This
setup will create a broad south to southwesterly fetch of warm,
moist air inundating the forecast region with PWATs between 1.7-2.1
inches. With general high pressure in the region accompanying the
tropical airmass, highs will remain in the low 90s with heat
indices in the high 90s and low- to mid-triple digits.

The biggest concern and divergence from the long term forecast comes
thanks to Potential Tropical Cyclone Six, which currently rests just
southeast of Puerto Rico. Over the last 24 hours, model guidance has
come to a consensus regarding the track of this storm which the
national Hurricane Center predicts will be just off the western
Florida peninsula, potentially making landfall in the eastern
Florida panhandle as a weak tropical storm or tropical depression.
However, forecast models can change quickly and forecast tropical
cyclone intensity is notoriously difficult to forecast this far
in advance. Either way, careful attention will need to be paid to
this storm as it approaches the Southeastern U.S., especially with
the track placing the forecast area on the 'dirty' side of the
storm where rainfall totals, higher wind gusts, and severe weather
are more likely to occur.

This Hazardous Weather Outlook is for portions of North and Central Georgia.

Scattered to numerous thunderstorms will be possible each day
Wednesday through Monday, most numerous during the afternoons and
