Areas affected...Extreme northeast Arkansas and the Missouri
Bootheel

Concerning...Tornado Watch 174...

Valid 282226Z - 290000Z

The severe weather threat for Tornado Watch 174 continues.

SUMMARY...A supercell migrating across far southeast Missouri and
northeast Arkansas may pose a locally higher severe threat over the
next 1-2 hours.

DISCUSSION...Surface observations across the MS Valley show a
stationary boundary/outflow draped across northern AR into KY. A
supercell with a history of producing severe hail and gusts up to 70
mph is approaching this boundary from the northwest along the
eastern MO/AR border. Although MRMS 50 dBz echo tops depict a recent
weakening trend with this storm, regional radar imagery has recently
begun to sample strengthening mid-level flow within the storm
(though precise feature identification is difficult given the
storm's distance from the nearest RDA). Further intensification
appears possible as the storm reaches the boundary where low-level
SRH is enhanced and a more moist/buoyant air mass resides on the
immediate warm side. This may support a localized corridor of higher
severe hail, wind, and tornado potential within the next 1-2 hours.
