AREAS AFFECTED...PORTIONS OF CNTRL/ERN IA

CONCERNING...SEVERE THUNDERSTORM WATCH 254...

VALID 150000Z - 150100Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 254
CONTINUES.

SUMMARY...A LARGE HAIL AND STRONG TO LOCALLY DAMAGING WIND THREAT
CONTINUES ACROSS ERN PORTIONS OF WW 254.

DISCUSSION...RADAR IMAGERY FROM KDMX SHOWS A WELL-DEFINED OUTFLOW
BOUNDARY FROM EARLIER CONVECTION ACROSS NRN IA/SRN MN MOVING SWD
ACROSS CNTRL IA WITH TIME. THIS BOUNDARY MAY ACT TO LIMIT STORM
LONGEVITY AND INTENSITY TO LOCATIONS TO ITS S AND E...NAMELY S-CNTRL
INTO SERN IA. THE AIRMASS ALONG AND S OF THE BOUNDARY REMAINS
MODERATELY UNSTABLE...WITH 23Z RAP MESOANALYSIS ESTIMATING MLCAPE
RANGING FROM 1500-2000 J/KG. VEERED SWLY WINDS AT THE SFC AND ALOFT
PER KDMX VWP SUGGEST ANY TORNADO THREAT SHOULD BE MINIMAL IN THE
OPEN WARM SECTOR. BUT STRENGTHENING WINDS WITH HEIGHT WILL CONTINUE
TO SUPPORT SOME STORM ORGANIZATION OVER THE NEXT SEVERAL
HOURS...WITH LARGE HAIL AND DAMAGING WINDS REMAINING THE MAIN
THREATS. IF CONVECTION IS ABLE TO DEVELOP ACROSS S-CNTRL IA
ALONG/AHEAD OF A COLD FRONT...THEN A SMALL LOCAL EXTENSION IN AREA
MAY BE NEEDED FOR WW 254.
