   Mesoscale Discussion 0101
   NWS Storm Prediction Center Norman OK
   0957 PM CST Sat Jan 21 2017

   Areas affected...Central and southern Alabama and parts of the
   Florida Panhandle into far southwest Georgia

   Concerning...Tornado Watch 17...

   Valid 220357Z - 220530Z

   The severe weather threat for Tornado Watch 17 continues.

   SUMMARY...Severe/tornado risk continues, particularly across
   southern and western portions of Tornado Watch 17.

   DISCUSSION...Latest radar loop shows a west-to-east band of
   strong/locally severe storms extending from southeast Mississippi
   east into far southwest Georgia, mainly to the cool side of the
   similarly aligned west-to-east warm front lying in the vicinity of
   the Florida/Alabama border.  North of the band of active updrafts --
   i.e. into the southeast quarter of Alabama and adjacent west-central
   Georgia -- an expanding area of stratiform/anvil precipitation is
   noted.  While this evolving MCS will continue shifting
   east-northeast with time, it appears that active/severe storms will
   remain limited to the southern fringe of the broader storm complex.

   Farther to the west, storms continue to shift east-northeast across
   central and southeast Mississippi into west central and southwest
   Alabama.  With less extensive stratiform-type precipitation falling
   northeast/upstream of this convection, inferring a more favorable
   airmass ahead of the storms, severe/tornado risk appears to be
   increasing across western and central Alabama in the short term.
