   Areas affected...Northern Georgia

   Concerning...Severe Thunderstorm Watch 145...

   Valid 041907Z - 042100Z

   The severe weather threat for Severe Thunderstorm Watch 145
   continues.

   SUMMARY...Damaging winds remain possible across northern Georgia for
   the next 1-2 hours. A gradual weakening trend is possible heading
   into the late afternoon hours.

   DISCUSSION...A few reports of wind damage have been noted across
   northern GA associated with the ongoing MCS across the northern and
   northeastern portion of the state. Recent reflectivity/velocity data
   from KFFC suggests that the MCS is becoming outflow dominant across
   north-central GA with a discernible outflow boundary outrunning the
   higher reflectivity. GOES IR imagery also points to a gradual
   weakening trend in the initial MCS as cloud tops begin to warm. A
   few stronger updraft pulses remain likely within remnants of the
   MCS, but will mainly be confined to northeast GA. 

   To the west, a bowing segment is emerging from northeast AL into
   northwest GA and has a history of producing at least sporadic wind
   damage and severe hail across AL. This segment is expected to move
   north of the outflow boundary from the GA MCS and into a cooler,
   more stable air mass. Strong velocities noted with this line (per
   KFFC) suggests wind damage remains possible for northwest GA for the
   next hour or so, but a gradual weakening seems likely as this
   activity continues northeast.
