Mesoscale Discussion 1999 NWS Storm Prediction Center Norman OK  0948 PM CST Fri Dec 10 2021 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. ..Bentley.. 12/11/2021   ...Please see www.spc.noaa.gov for graphic product...
