Areas affected...western KS

Concerning...Severe potential...Watch possible=20

Valid 032049Z - 032245Z

Probability of Watch Issuance...40 percent

SUMMARY...Isolated strong to severe thunderstorms will track
south/southeast across western Kansas through early evening. Large
hail and strong gusts are possible with the strongest storms.

DISCUSSION...Isolated thunderstorms have developed this afternoon
along the strong moisture gradient across northwest KS. Steep
midlevel lapse rates near 8 C/km are aiding in moderate to strong destabilization with MLCAPE values near 2000-2500 J/kg. While
vertical shear is somewhat modest across northwest KS, these storms
will encounter stronger effective shear magnitudes greater than 30
kt as they track south. These storms will also move into the more
moist boundary layer. As a result, additional convection or
intensification is possible with time and southward extent. The
favorable thermodynamic and kinematic environment will support
isolated large hail. Additionally, some guidance suggests clustering
could occur toward evening. If this scenario occurs, damaging wind
potential could increase as well. Trends will be monitored for
possible watch issuance.
