.SHORT TERM...
(Today through Thursday)
Issued at 316 AM EDT Wed Jun 12 2024

Old frontal boundary remains stationary across the panhandle of
Florida. A couple of waves of low pressure are progged to move east
along the boundary through the short term period. Some isolated pops
are possible in far SE GA Thursday afternoon (closest to the
boundary/lows), but for most areas the forecast will remain dry.
Temps slightly above normal through the period.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 316 AM EDT Wed Jun 12 2024

Broad and wide mid/upper level ridging will dominate much of the
long term. Temperatures will continue to climb through Saturday,
when highs could potentually reach 100 degrees in portions of
Central GA. Models continue to struggle with moisture transport out
of the Gulf as they struggle to get a handle on the development of a
gulf sfc low. Recent trends are catching on a weak sub-tropical jet
shortwave which helps to develop something over the Florida
Panhandle before sending it off into the Atlantic. NE flow
associated with this low could certainly dry us out more than
expected as we go into the weekend. PWATs seem to reflect this
hanging near 1 to 1.5" in both the GFS and ECMWF as well as the GEFS
mean. This would put us just below normal for this time of year. Dry
air would mean both reduced heat indices and PoPs. The NBM seems to
reflect this by keeping PoPs out of the area through early next
week, though given the uncertainty in moisture transport and
incoming shortwave energy, will likely bring low PoPs into Central
GA through early next week.

Speaking of early next week, a building sub-tropical jetstreak over
Arkansas and the Mid-Mississippi valley will once again draw
moisture out of the Gulf and provide more robust PoPs across North
and Central GA. CAPE values will be conducive to our normal
diurnally driven pulse convection. Greater precipitation coverage
will help to moderate out temperatures, however this will likely be
traded for a classic "Southeast Sauna".
