   Areas affected...central into north-central Indiana

   Concerning...Tornado Watch 318...

   Valid 120119Z - 120245Z

   The severe weather threat for Tornado Watch 318 continues.

   SUMMARY...A swath of 65 to 85 mph winds are expected across central
   to north-central Indiana this evening.

   DISCUSSION...A mature bow-echo has developed across east-central
   Illinois with a strong rear-inflow jet. This bow has left a large
   swath of wind damage over the past hour including a measured 68 mph
   wind gust in Champaign, IL. 65 to 85 mph winds are expected to
   continue across a relatively wide swath as it moves east into a very
   unstable environment through the evening. Some embedded QLCS
   tornadoes will also be possible, especially north of the apex of the
   bow, but the strong measured wind gusts will be the primary threat.
