   FAVORABLE FOR POSSIBLE REDEVELOPMENT...PRIMARILY ALONG A REMNANT
   OUTFLOW BOUNDARY FROM THE MCS TO THE NE...AND ALONG THE DRYLINE IN
   WRN PORTIONS OF THE WATCH. AIRMASS REMAINS VERY UNSTABLE...WITH
   CLEARING IN CLOUDS ALLOWING FOR AMPLE SURFACE HEATING. MOIST INFLUX
   FROM THE SSE WILL REMAIN CONDUCIVE TO DEVELOPMENT OF STORMS. SHOULD
   STORMS REDEVELOP...STRONGER FLOW ACROSS THE AREA COMPARED TO AREAS
   TO THE N...AND BACKED WINDS AT THE SURFACE WILL BE FAVORABLE FOR
   SUSTAINED UPDRAFTS AND SUPERCELLS CAPABLE OF PRODUCING DMGG
