Areas affected...portions of eastern Nebraska into northern Kansas
and western Iowa

Concerning...Tornado Watch 213...214...

Valid 172353Z - 180100Z

The severe weather threat for Tornado Watch 213, 214 continues.

SUMMARY...Severe wind and hail remain a concern with ongoing storms
over eastern NE into western IA and northern KS. Focused corridors
of severe wind, with isolated QLCS tornadoes, may accompany mature
bowing segments.

DISCUSSION...The cold front continues to surge southward and merge
with the dryline, which may be at least partially contributing to
the rapid upscale growth of ongoing multicells and supercells into
line segments. Should this trend continue, then severe wind will
become the main threat in a couple of hours, with a secondary risk
of hail and isolated QLCS tornadoes. Bowing segments may be capable
of producing focused corridors of 50+ kt gusts, with some exceeding
65 kts in magnitude. QLCS tornadoes are also most likely with the
bowing segments.

Supercell tornado potential seems more conditional given the
prominent mixed/linear storm modes. One storm in Thayer County, NE
is attempting to maintain supercell structure and currently contains
a tornado. Given strong instability and vertical wind shear in
place, any discrete supercell that can sustain itself will have a
conditional potential to produce a strong tornado.
