AREA WEATHER UPDATE
NATIONAL WEATHER SERVICE NORMAN OK
800 PM CDT SUN JUL 3 2005

...WARNING DECISION UPDATE...

..THIS WARNING DECISION UPDATE CONCERNS NORTHERN OKLAHOMA...

HP SUPERCELL/BOW COMPLEX NEAR WICHITA SEEMS TO BE TRENDING MORE 
TOWARD LARGE BOW ECHO STRUCTURE WITH TIME..WHILE SLOWLY BEGINNING TO 
ACCELERATE SEWD. VOLUMETRIC Z DATA FROM KTLX INDICATES THAT THIS 
CONVECTION REMAINS VERY INTENSE WITH VERY DEEP Z CORES THAT WILL 
APPROACH N CENTRAL OK 815-845 PM.

ALSO OF INCREASING CONCERN FOR LATER THIS EVENING IS HP 
SUPERCELL/BOW ECHO COMPLEX NOW MOVING ACROSS SW KANSAS THAT HAS A 
MUCH FASTER FORWARD MOVEMENT. INCREASING LOW LEVEL JET WILL FEED 
LARGE RESERVOIR OF HIGH TO EXTREME INSTABILITY OVER OK /CAPES AOA 
4000/ INTO THIS COMPLEX AS IS MIGRATES SEWD OVER NEXT SEVERAL 
HOURS..AND EXPECT THIS COMPLEX TO BE ACCOMPANIED BY HIGH-END 
WIND/HAIL THREAT AS IT MOVES INTO FAR NW OKLAHOMA 03-04Z.

KVNX RADAR REMAINS DOWN..AND WE WILL USE KDDC/KICT VELOCITY DATA AS 
BEST AS POSSIBLE TO RESOLVE LOW LEVEL FEATURES..AND WILL USE 
VOLUMETRIC Z/V DATA FROM KTLX..SUPPLEMENTED BY KDDC/KICT. LARGE Z 
CORES AND LARGE CIRCULATIONS EVIDENT ALL EVENING IN STORMS OVER SRN 
KS SUGGEST GOLFBALL/BASEBALL HAIL AND 80 MPH WIND THREAT WITH ANY 
SUPERCELL/BOW COMPLEX WITH 50DBZ CORES ABOVE 30 KFT.
