AREAS AFFECTED...NEB...NRN KS

CONCERNING...SEVERE THUNDERSTORM WATCH 779...

VALID 130124Z - 130300Z

...CONVECTION IS GRADUALLY WEAKENING ACROSS SRN PORTIONS OF THE
WATCH...

LOSS OF DAYTIME HEATING/BOUNDARY LAYER INSTABILITY APPARENTLY HAS
CONTRIBUTED GREATLY TO THE DEMISE OF EARLIER SEVERE SUPERCELL
ACTIVITY OVER OSBORNE COUNTY KS.  SEVERAL STRONG UPDRAFTS
REMAIN...ESPECIALLY ACROSS NERN NEB WHERE LOW LEVEL CONVERGENCE IS A
BIT STRONGER.  LATEST VIS/RADAR IMAGERY SUGGEST STRONG FORCING
REMAINS ABOUT 150MI UPSTREAM WHERE SRN EXTENT OF WELL DEFINED
BAROCLINIC LEAF IS MOVING ACROSS THE NEB PANHANDLE.  THIS MAY
ENHANCE CONVECTION ALONG LEAD CONFLUENCE ZONE LATE THIS EVENING.
