Areas affected...Southeast Iowa
Concerning...Tornado Watch 93...

CORRECTED FOR AREAS AFFECTED
The severe weather threat for Tornado Watch 93 continues.
SUMMARY...Likely strong tornado (upper EF2 to EF3) ongoing northeast
of Ottumwa. The downstream environment will continue to support the
potential for a strong tornado.
DISCUSSION...A supercell northeast of Ottumwa has shown increasing
low-level rotation with a tornado recently confirmed. Current VROT
observations from KDMX are around 60 kts. Given the environment,
this would suggest a strong tornado (EF2-EF3) is likely ongoing. The
deepening surface low and continued backed surface winds in eastern
Iowa will continue to support a strong/intense tornado threat as
this storm continues to the north and east.
