KANSAS INTO THE EASTERN TEXAS PANHANDLE AND SOUTH PLAINS...
A few strong to locally severe storms with gusty winds and marginal
hail remain possible over the southern High Plains.
...Southwest KS into the TX Panhandle...
Isolated strong cells currently exist near a surface trough
extending from southwest KS into the eastern TX Panhandle and South

southward-moving cells with periodic strong cores.
Capping is forecast to remain relatively weak during the evening
where low-level lapse rates are strongest, with northerly winds
aloft aiding storm motions into parts of the South Plains. A
marginal hail and wind risk may thus persist through at least 03Z,
and perhaps a bit longer, within the narrow north-south plume of
