Areas affected...northwest/north-central KS and south-central NE

Concerning...Severe potential...Tornado Watch likely=20

Valid 061557Z - 061800Z

Probability of Watch Issuance...95 percent

SUMMARY...An arc of severe thunderstorms should develop by early
afternoon along the composite cold front/dryline. Tornadoes, large
hail, and severe wind gusts are expected with a midday tornado watch
issuance.

DISCUSSION...15Z surface analysis placed the composite cold
front/dryline across southwest NE into far western KS. A lobe of
large-scale ascent indicated by a patch of upper-level cirrus along
the KS/CO border will rapidly spread northeast and likely aid in
convective development along the KS/NE border area during the next
few hours. A plume of at least moderate buoyancy is already present,
with earlier MLCIN noted in 12Z LBF/DDC soundings waning.
Enlarged/elongated hodographs will favor supercell structures,
especially with southern extent where a couple strong tornadoes will
be possible. Linear frontal forcing and potential for pinching of
the northeast portion of the surface-based buoyancy plume should
yield greater potential for upscale growth earlier with northern
extent. A mix of tornadoes, large hail, and severe wind gusts is
expected.
