   ...SYNOPSIS...
   A PROGRESSIVE PATTERN WILL BE IN PLACE SUNDAY WITH A LARGE AND
   INTENSE UPPER TROUGH EXITING THE ERN SEABOARD EARLY AND ANOTHER
   TROUGH AMPLIFYING ACROSS THE ROCKIES AND INTO THE PLAINS OVERNIGHT.
   AT THE SURFACE...HIGH PRESSURE WILL BE CENTERED OVER THE ERN GULF OF
   MEXICO AND SERN STATES AND WILL MAINTAIN DRY CONDITIONS THERE. 
   
   AS THE WRN TROUGH MOVES ACROSS THE ROCKIES...DAYTIME HEATING MAY
   CREATE VERY WEAK INSTABILITY DUE TO COOL AIR ALOFT. THIS COULD
   RESULT IN A ROGUE LIGHTNING STRIKE ANYWHERE FROM THE YELLOWSTONE
   AREA INTO THE FOUR CORNERS REGION...BUT COVERAGE SHOULD REMAIN VERY
   LIMITED.
   
   OVERNIGHT AS HEIGHT FALLS OCCUR ACROSS THE PLAINS...SLY LOW LEVEL
   FLOW WILL BEGIN TO BRING MOISTURE NWWD ACROSS THE WRN GULF OF MEXICO
   AND INTO TX...BUT THE AIR MASS WILL BE COOL AND CAPPED.
