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.
