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.

Areas affected...Western Kansas into southern Nebraska

Concerning...Blizzard=20

Valid 082048Z - 090045Z

SUMMARY...Blizzard conditions continue into the evening.

DISCUSSION...Winds continue to strengthen across western Kansas with
sustained winds as high as 44 knots at KULS with numerous locations
reporting blizzard conditions. Winds may still strengthen further
over the next few hours as the northerly low-level jet continues to strengthen/broaden on the western periphery of the 850mb low. Strong
cold air advection also continues with temperatures in the low 20s
now across northwest Kansas. Moderate to heavy snowfall within the
deformation band will slowly drift east through the evening as the
surface low advances eastward. Blizzard conditions will continue
across western Kansas and into southern Nebraska through this period
with only slow improvement from west to east.
