   Areas affected...northwest Indiana

   Concerning...Tornado Watch 313...318...

   Valid 120044Z - 120215Z

   The severe weather threat for Tornado Watch 313, 318 continues.

   SUMMARY...A strong to intense tornado threat will exist for the next
   1 to 2 hours.

   DISCUSSION...A cluster of supercells across northwest Indiana has a
   history of tornadoes including a likely strong tornado across Lake
   County within the past 15 minutes. The southernmost storm in this
   cluster across northern Newton County is exhibiting broad, strong
   rotation and is in a similarly favorable tornado environment
   featuring STP around 5. This supercell is expected to remain
   discrete/undisturbed and will likely pose a strong to potentially
   intense tornado threat across southern Porter, Laporte, and
   potentially St. Joseph county for the next 1 to 2 hours.
