yoda Posted December 11, 2021 Share Posted December 11, 2021 Mesoscale Discussion 2008 NWS Storm Prediction Center Norman OK 1153 PM CST Fri Dec 10 2021 Areas affected...Portions of northern Kentucky. Concerning...Tornado Watch 554... Valid 110553Z - 110700Z The severe weather threat for Tornado Watch 554 continues. SUMMARY...A strong tornado threat continues across portions of northern Kentucky. DISCUSSION...Storm interference from new cells merging has finally disrupted the persistent very strong low-level mesocyclone with the long-lived supercell now entering Breckenridge County, Kentucky. However, while this has weakened the intensity of the updraft and low-level rotation, a strong tornado with around 50 to 55 knot Vrot and a TDS is still present. Mid 60s dewpoints have advected ahead of this storm and therefore, adequate instability remains for strong tornado development given the 350 to 400 m2/s2 0-1 km SRH per the KLVX VWP. Therefore, while circulations may be weaker and more transient, a strong tornado threat persists. Link to comment Share on other sites More sharing options...
