The severe weather threat for Tornado Watch 119, 120 continues.
SUMMARY...Risk for additional tornadoes and locally damaging wind
gusts may persist into the 4-5 AM CDT time frame. A new WW may be
issued or Tornado Watch 119 locally extended.
DISCUSSION...A developing mesoscale convective vortex is now near
the Jonesboro AR vicinity and migrating northeastward around 40 kt,
with a narrow vigorous line of convection arcing southward toward
the Greater Memphis area. To the south of stalling convective
outflow, near the lower/mid-tropospheric vorticity center
east-northeastward toward areas near/north of Hopkinsville and
Bowling Green, one notable supercell has evolved within the
convective line and may have recently produced a tornado to the
west-northwest of Memphis.
Along and south of the stalled outflow, there appears a narrowing
corridor of modest potential boundary-layer instability to main a
continuing risk for tornadoes and/or locally damaging wind gusts
another several hours, in the presence of strong low-level and
deep-layer shear.
