MESOSCALE DISCUSSION 1121
NWS STORM PREDICTION CENTER NORMAN OK
0558 PM CDT SUN JUN 22 2014

AREAS AFFECTED...SERN IA...NERN MO...WRN IL

CONCERNING...SEVERE THUNDERSTORM WATCH 345...

VALID 222258Z - 230030Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 345
CONTINUES.

SUMMARY...A MARGINAL SEVERE WIND/HAIL RISK CONTINUES IN AND NEAR THE
REMAINING PART OF WW 345. DUE TO LARGELY DISORGANIZED NATURE OF THE
THREAT...DOWNSTREAM WW ISSUANCE IS NOT ANTICIPATED.

DISCUSSION...AT 2250Z...TWO LOOSELY ORGANIZED CONVECTIVE LINES WERE
ONGOING...ONE ACROSS WRN IL WEST OF PIA AND ANOTHER ACROSS FAR SERN
IA/WRN IL INTO NERN MO. ADDITIONAL MORE ISOLATED CELLS HAVE RECENTLY
DEVELOPED NEAR PIA. THUS FAR...ACTIVITY HAS BEEN TOO DISORGANIZED TO
PRODUCE A ROBUST SEVERE RISK...BUT SOME THREAT WILL PERSIST INTO
PARTS OF WRN/CNTRL IL WHERE STRONG INSTABILITY IS IN PLACE. IMMINENT
CELL MERGERS NEAR/NORTH OF PIA MAY RESULT IN A SHORT-TERM INCREASE
IN STORM INTENSITY EAST OF WW 345...WITH OTHER CELLS PULSING UP INTO
NERN MO IN THE INSTABILITY AXIS. WITH WEAK FLOW THROUGHOUT THE
TROPOSPHERE ACROSS THE REGION...MAINTENANCE OF AN ORGANIZED SEVERE
THREAT IS NOT EXPECTED AND DOWNSTREAM WW ISSUANCE SHOULD NOT BE
NECESSARY.
