   winds with storms expected to generally spread southeastward through
   the evening.

   The severe thunderstorm watch area is approximately along and 75
   statute miles north and south of a line from 40 miles west northwest
   of Auburn AL to 35 miles east southeast of Spartanburg SC. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU0).

   favorable for severe thunderstorms in and close to the watch area.

   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.
