Mesoscale Discussion 1193
NWS Storm Prediction Center Norman OK
1238 AM CDT Thu Jul 08 2021
Areas affected...eastern South Carolina...southeastern North
Concerning...Tornado Watch 347...
Valid 080538Z - 080745Z
The severe weather threat for Tornado Watch 347 continues.
SUMMARY...Tornado risk continues east and northeast of the center of
Tropical Storm Elsa. As risk spreads northeastward with time, a new
tornado watch will be required (within the next 1/2 hour or so).
DISCUSSION...Latest radar loop shows several small/rotating cells --
mainly embedded within the primary convective band which is now
beginning to shift into the Charleston metro area. This band is
currently advancing northward at around 25 kt -- which will place
this band near the northern fringe of the watch by 0630Z -- about an
hour from now. With the latest VWP from the KCLX WSR-88d showing
low-level flow veering rapidly with height yielding 35-40 kt 0-1km
shear, and dewpoints well into the mid to upper 70s across the
coastal tier or two of counties, expect low-level rotation -- and
potential for occasional tornadic spin-ups -- to continue over the
next several hours. A new WW will be required -- that will extend
northward into southeastern North Carolina.
