Areas affected…southwestern Nebraska into northwestern Kansas
Concerning…Tornado Watch 273…
Valid 210629Z – 210730Z
The severe weather threat for Tornado Watch 273 continues.
SUMMARY…A cluster of intense storms continues moving eastward
across southwestern Nebraska and adjacent northwestern Kansas.
All-hazards severe risk is evident.
DISCUSSION…A well-organized, broadly rotating storm is currently
observed crossing the Hayes/Hitchcock County vicinity in Nebraska,
with trailing storms extending southwestward to Cheyenne County
Kansas. The storms are ongoing just north of the conglomerate
surface front/outflow lying west-southwest to east-northeast across
northwestern Kansas and into central and southeastern Nebraska. As
such, this region is on the northern gradient of surface-based
instability, and thus capable of producing all-hazards severe
weather — given favorably strong/sheared background flow. This
convection should maintain intensity as it shifts eastward toward —
and eventually into — WW 274, aided by the observed 60-kt low-level
jet.
