CONCERNING...SEVERE THUNDERSTORM WATCH 224...

VALID 272200Z - 272330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 224
CONTINUES.

SUMMARY...ISOLATED SEVERE STORMS CAPABLE OF BRIEF TORNADOES AND HAIL
WILL CONTINUE OVER PARTS OF WESTERN KS FOR ANOTHER 1-2 HOURS.

DISCUSSION...RADAR LOOP SHOWS SEVERAL SEMI-DISCRETE STORMS THAT ARE
FORMING EAST OF A SURFACE LOW NEAR GREELEY COUNTY KS...AND ALONG
ALONG THE PACIFIC COLD FRONT EXTENDING EASTWARD INTO CENTRAL KS.
SOUTHERLY-ORIENTED DEEP LAYER SHEAR VECTORS ARE NORMAL TO THE E-W
BOUNDARY...ALLOWING CELLS TO REMAIN MOSTLY DISCRETE.
MEANWHILE...STORMS ARE TRACKING WESTWARD AND REMAINING IN THE
VICINITY OF THE BOUNDARY.  THIS ALLOWS THE UPDRAFTS TO INTERACT WITH
ENHANCED LOW-LEVEL VORTICITY AND SHEAR AND IS LEADING TO SEVERAL
BRIEF TORNADO REPORTS.  THIS PROCESS MAY CONTINUE FOR ANOTHER HOUR
OR TWO UNTIL STORMS EXHAUST THE INSTABILITY ALONG THE BOUNDARY AND
DAYTIME HEATING ENDS.  STRONGER UPDRAFTS ALONG THIS CORRIDOR WILL
ALSO POSE A THREAT OF LARGE HAIL.
