Valid 092215Z - 092345Z
The severe weather threat for Tornado Watch 714, 715 continues.
SUMMARY...A short-term tornado threat continues with ongoing
supercells.
DISCUSSION...At 2215 UTC, long-lived supercells are ongoing north
and west of Nashville, within an environment characterized by modest
instability but favorable low-level and deep-layer shear. Recent
VWPs from KOHX depict 0-1 km SRH of greater than 200 m2/s2, which
will continue to support a tornado threat for as long as instability
remains sufficient. While an increase in storm coverage and tendency
toward more of a linear mode is expected with time, the ongoing
supercells are sufficiently ahead of the cold front to remain
relatively discrete in the short term as they move quickly
east-northeastward across northern middle TN.
