Areas affected...southern Missouri and northern Arkansas
Concerning...Tornado Watch 311...314...
Valid 260912Z - 261045Z
The severe weather threat for Tornado Watch 311, 314 continues.
SUMMARY...Severe/tornado risk continues across southern Missouri and
northern Arkansas.
DISCUSSION...Latest radar loop shows complex clustering of
severe/supercell storms, including spin-up of several small
low-level circulations -- and associated/brief tornadoes -- in the
past half hour over southern Missouri. Meanwhile, the two more
substantial/long-lived supercells -- one now moving
east-southeastward across Stone County Missouri and the other
crossing Marion County Arkansas -- both remain capable of producing
all-hazards severe weather. The Marion County storm, in particular,
appears to have produced a tornado over the past 15 minutes per
WSR-88D correlation coefficient.
Severe potential will likely continue/spread eastward over the next
few hours. Gradually, storms will vacate eastern portions of
Tornado Watch 311, and move fully into Tornado Watch 314. However,
storms may not fully clear WW 311 prior to its scheduled 10Z
expiration -- possibly requiring an EXT to cover the ongoing risk.
