AREAS AFFECTED...SERN NEB...NERN KS
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 021222Z - 021315Z
CONVECTION WILL CONTINUE TO MOVE ESEWD WITH A MAIN THREAT OF LARGE
HAIL. DMGG WIND THREAT MAY INCREASE LATER THIS MORNING. A NEW WATCH
DOWNSTREAM OF WW #0418 MAY BE NECESSARY.
CONVECTIVE INTENSITY HAS BEEN INCREASING OVER THE PAST HOUR OVER
PORTIONS OF SRN NEB AS A DEVELOPING MCS CONTINUES TO TRACK ESEWD.
LOW LEVEL JET AND THETA-E ADVECTION IN COMBINATION WITH STEEP MID
LEVEL LAPSE RATES HAS AIDED IN DEVELOPMENT OF A MCS THIS MORNING.
SHEAR PROFILES AND MODERATELY UNSTABLE AIR MASS ABOVE 700 MB AS
SHOWN ON 12Z NEB SOUNDINGS WILL CONTINUE TO SUPPORT A RISK OF LARGE
HAIL. OVER THE NEXT FEW HOURS...DMGG WIND THREAT WILL INCREASE AS
SURFACE HEATING MINIMIZES LOW LEVEL CAPPING OBSERVED ON SOUNDINGS
EAST OF CURRENT CONVECTION...AND ALLOWS STRONGER WINDS TO MIX TO THE
SURFACE.
