Areas affected...Northern Louisiana...Southeast Arkansas...Northwest
Mississippi...Western Tennessee

Concerning...Tornado Watch 3...4...5...

Valid 030736Z - 030930Z

The severe weather threat for Tornado Watch 3, 4, 5 continues.

SUMMARY...A severe threat will likely continue across watches 3, 4
and 5 for several more hours, with tornadoes and wind damage being
the primary threats. Consolidation of the watches will likely take
place within the next two hours.

DISCUSSION...The latest mosaic radar imagery shows a large area of
thunderstorms from southeast Missouri and western Kentucky extending
southwestward into eastern Arkansas. A few rotating storms are
embedded within the complex, along with several short bowing line
segments. As this area of moderate to heavy rainfall moves eastward,
the severe threat will continue across western Kentucky, western
Tennessee, northwest Mississippi and northeast Louisiana. Although
instability is generally weak, WSR-88D VWPs at Memphis and Paducah
have long hodographs with some curvature. 0-6 km shear is generally
around 60 kts with 0-3 km storm-relative helicity near 500 m2/s2.
This environment will continue to support a threat for tornadoes
over the next few hours. Bowing line segments will also have=20
potential for wind damage.
