Areas affected...portions of southeastern Kansas...northern Oklahoma
and the far eastern Texas Panhandle.

Concerning...Severe potential...Watch unlikely

Valid 112016Z - 112215Z

Probability of Watch Issuance...20 percent

SUMMARY...Scattered storm development later this afternoon may pose
a risk for sporadic damaging gusts and some hail. A WW is unlikely.

DISCUSSION...Boundary-layer destabilization is underway across much
of the southern and central Plains ahead of a slow-moving cold
front. Afternoon satellite imagery showed strong surface heating was
resulting in gradual deepening of cumulus along and ahead of the
front from eastern KS to northern OK. As continued heating and weak
ascent from a passing upper-level trough overspread the area, a
gradual increase in thunderstorms is expected this afternoon and
evening. Focused largely along the front, modest vertical shear will
favor a complex mode of multi cell clusters. 1500-2000 J/kg of
MLCAPE observed from the 18z LMN/AMA soundings will support
transient stronger updrafts capable of some hail with these storms.
A deep and well-mixed boundary layer with prominent inverted-V
structure should also support occasional stronger downdrafts capable
of damaging gusts.

Observational trends and recent CAM data suggest storm development
will occur first along the front across eastern KS before spreading
southwest into northern OK and the TX Panhandle. As storm clusters
and outflow begin to amalgamate, the risk for damaging gusts will
slowly increase into early evening. Given the limited storm
organization a WW is not expected.
