Mesoscale Discussion 0531
NWS Storm Prediction Center Norman OK

Areas affected…East-central MO into west-central IL
www.spc.noaa.gov/products/md/md0531.html
Concerning…Tornado Watch 139…
Valid 152207Z – 152330Z
The severe weather threat for Tornado Watch 139 continues.
SUMMARY…A significant wind threat will spread toward the
Mississippi River over the next 1-2 hours, in addition to a
continued risk of very large hail and a tornado or two.
DISCUSSION…Multiple cell mergers have resulted in the development
of a large and intense HP supercell structure that recently moved
out of Maries County, MO. Strong midlevel rotation has been noted
with this cell on radar, and a 97 mph measured gust was reported at
2141 UTC near Vichy, MO. Additional upscale growth appears likely,
with additional cell development noted both north and south along
the larger-scale outflow, and also ahead of the ongoing convection
across Franklin County, MO. This may result in the development of a
bowing segment that will approach the MS River with a continued
significant-wind threat.
