   Areas affected...Portions of Northern Alabama and Georgia into
   central and eastern Tennessee

   Concerning...Severe potential...Watch unlikely 

   Valid 031654Z - 031900Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Scattered thunderstorms -- some of which may be marginally
   severe -- are expected to develop and increase in coverage across
   much of the Southeast this afternoon. The strongest storms will be
   capable of damaging wind gusts of 60 MPH.

   DISCUSSION...Surface temperatures across much of the Southeast have
   reached the low 90s F, and as heating begins to reach convective
   temperature, thunderstorms are expected to increase in coverage and
   intensity. Being beneath an upper-level ridge, there is little in
   the way of vertical shear to support storm organization. However,
   loose clusters of multicellular thunderstorms will develop in
   well-mixed boundary layers with steep lapse rates, modest
   precipitable water content, and relatively high LCLs. This should
   support strong, wet downdrafts, with SPC Mesoanalysis indicating
   downdraft CAPE exceeding 1000 J/kg across much of the area. Along
   with the potential for wet microbursts, the scattered storm coverage
   can also result in loose organization along interacting outflow
   boundaries. Both scenarios could result in 60 MPH wind gusts and
   some wind damage. However, the overall pulse-convection nature and
   lack of clear organization mechanisms limits the confidence in
   severe coverage. While a severe thunderstorm watch is not
   anticipated at this time, conditions will continue to be monitored
   as convective coverage increases.
