Areas affected...Southwest KS...OK/TX Panhandle Region

Concerning...Severe potential...Watch likely

Valid 281921Z - 282045Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe thunderstorms are expected across the High Plains
from southwest Kansas into the Texas Panhandle. Large hail and
damaging winds can be expected.

DISCUSSION...Strong boundary-layer heating is contributing to air
mass destabilization across the High Plains. Latest OA data suggests
surface parcels are nearing convective temperatures as lowest 2km
lapse rates are now in excess of 9.5 C/km. Visible imagery supports
this with cu field expanding/deepening from Lane County to Gray
County in southwest KS. Other high-based cu is forming in the
northwest TX Panhandle. Over the next few hours it appears scattered
supercells will evolve along this corridor and latest CAM guidance
is supportive in this scenario. While a tornado can not be ruled out
with strongest supercells, especially over KS, large hail and
damaging winds are the primary threats.
