Areas affected...Portions of western Kentucky

Concerning...Tornado Watch 552...554...

Valid 110348Z - 110445Z

The severe weather threat for Tornado Watch 552, 554 continues.

SUMMARY...A strong to potentially violent tornado is ongoing and
expected to continue for at least another hour.

DISCUSSION...A strong supercell with a history of a long-track
tornado with intense to potentially violent damage has recently
intensified once again across southwest Kentucky. Latest radar and
environmental analysis give high confidence that an intense to
potentially violent tornado has occurred across southwest Kentucky.
The radar presentation of this storm continues to be extremely
favorable for continued intense, long-lived tornadoes. Nearby
convection has mostly dissipated which may allow a more steady-state
to continue as it moves northeast. The downstream environment
remains very favorable with upper 60s to low 70s dewpoints and
backed surface winds with STP around 5 to 6. Eventually, expect
storm activity to the west to catch this supercell, but until that
happens, continued strong to potentially violent tornadic damage is
expected to continue along its path.
