   THROUGH LATE MORNING AND CONTINUE INTO THE AFTERNOON. RATES OF 1-2
   INCHES PER HOUR WILL BE COMMON ACROSS THE AREA.
   
   INTENSE ASCENT WITHIN THE DEFORMATION ZONE OF THE STRONG
   EXTRATROPICAL CYCLONE OVER THE NERN CONUS WILL SUPPORT SNOWFALL
   RATES OF 1 TO 2 INCHES ACROSS MUCH OF THE DISCUSSION AREA AFTER 16Z.
   HOWEVER...STRONG 850-700-MB FRONTOGENESIS WILL AUGMENT THE ASCENT TO
   SUPPORT A CORRIDOR OF 2-3 INCH/HOUR RATES WITHIN A 40-60-MILE WIDE
   CORRIDOR CENTERED ALONG A LINE FROM 15 MILES NNW OF KBTV TO 30 MILES
   NNW KEPM. IN THIS REGION...13Z RUC FORECAST SOUNDINGS INDICATE THE
   ASCENT COINCIDING WITH DEEP DENDRITIC GROWTH ZONES /AOA 150 MB
   THICK/ SUPPORTING VERY EFFICIENT SNOW GROWTH. ADDITIONALLY...
   PRECIPITATION ACROSS SRN PORTIONS OF THE DISCUSSION AREA COULD
   EXPERIENCE A CONVECTIVE ENHANCEMENT WITH THE POTENTIAL FOR AN
   ISOLATED LIGHTNING STRIKE...AS MID-LEVEL LAPSE RATES STEEPEN AOA 7
   C/KM PER THE RUC MODEL. THE 12Z EXPERIMENTAL HRRR INDICATES HEAVY
   SNOWFALL RATES CONTINUING THROUGH MID-AFTERNOON...WITH RATES
   BEGINNING TO TAPER OFF FROM WEST TO EAST FROM 20Z TO 23Z.
