AREAS AFFECTED...SRN SD...NRN NEB

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 010327Z - 010500Z

...CONVECTIVE THREAT IS INCREASING ACROSS MUCH OF SRN SD AND NRN
NEB...

THUNDERSTORMS HAVE RECENTLY INTENSIFIED ACROSS SCNTRL SD/NCNTRL NEB
AHEAD OF AN APPARENT WEAK SHORTWAVE TROUGH.  THIS FEATURE HAS
ALLOWED LOW LEVEL WINDS TO BACK AHEAD OF CONVECTION FORCING A ZONE
OF ENHANCED CONVERGENCE AND INCREASING MOISTURE TO RETURN WWD INTO
THE CNTRL PLAINS.  WITH A SIGNIFICANT ELY COMPONENT NOW OBSERVED
ACROSS SRN SD...IT APPEARS LOW LEVEL WARM ADVECTION MAY BE
INCREASING ALONG THE SD/NEB BORDER.  CONVECTION MAY CONTINUE TO
INCREASE AS IT SPREADS EWD WITH SUFFICIENT LAPSE RATES TO WARRANT AT
LEAST AN ISOLATED LARGE HAIL THREAT.  WW IS NOT ANTICIPATED AT THIS
TIME.
