Areas affected...Western GA...Central FL Panhandle...Far Eastern
AL...

Concerning...Heavy rainfall...Flash flooding possible

Valid 260420Z - 260900Z

SUMMARY...A few more hours of potential training, highly efficient
convection capable of 2.5"/hr and a streak or two of 2-4" totals
resulting in possible localized flash flooding.

DISCUSSION...Regional RADAR and 10.3um EIR from GOES-E continue to
show flare-ups of convection along the eastern edge of the warm
conveyor belt which appears to be at the near eastern limit of
influence from the parent larger-scale decaying closed low in
Eastern Texas.  The warm conveyor continues to pump enhanced
moisture through a deep fairly unidirectional south to north
stream from the east-central Gulf northward along the AL/GA line.=20
An equally narrow axis of instability remains along the eastern
edge of the q-axis with solid overlap.  Surface easterly flow has
recently intersected the north-south boundary and new convection
has developed along it.  Given upstream elongated vorticity
strip/shortwave over the north-central Gulf lifting north,
combined with weak to moderate divergence at the entrance to the
northeastward angling upper-level jet streak across the southern
Appalachians, will help to maintain any of these localized low
level convergence maxima that spark another round of convection;
this included southerly frictional convergence at the Gulf/Florida
Panhandle interface, especially as the sfc convergence retrogrades
west deeper into the q-axis.=20=20

Total PWat values of 2-2.25" and narrow skinny CAPE profiles (up
to 1500 J/kg) with 20-30kts of LLJ inflow/flux convergence has and
will likely to aid 2-2.5"/hr rates and with stronger flow off the
Gulf, flanking line redevelopment can support back-building edges
parallel to the deep layer steering allowing for localized 2-4"
localized streaks.  This may result in an incident or two of
localized rapid inundation/flash flooding for prone areas and
intersected urban centers.   All in all, flash flooding is
considered possible in an isolated to widely scattered manner
through the overnight period.
