.PREV DISCUSSION... /ISSUED 433 AM CST THU NOV 20 2014/

DISCUSSION...
FORECAST PHILOSOPHY REMAINS THE SAME. SURFACE BOUNDARY OVER NORTH
TEXAS WILL PROVIDE FOCUS FOR ISENTROPIC LIFT TONIGHT AS LOW-LEVEL
MOISTURE ADVECTS NORTHWARD FROM THE GULF OF MEXICO. THIS WILL GIVE
PRECIPITATION CHANCES BEGINNING TONIGHT... ESPECIALLY ACROSS
SOUTHEAST OKLAHOMA. ALTHOUGH PRIMARY ASCENT MOVES TO THE EAST
TOMORROW... THERE IS STILL ENOUGH OVER THE FORECAST AREA TO
CONTINUE POPS INTO TOMORROW. THE PRIMARY LONGWAVE TROUGH BEGINS TO
APPROACH FROM THE WEST AND WIDESPREAD PRECIPITATION LOOKS LIKE A
SOLID BET FRIDAY NIGHT AND ESPECIALLY SATURDAY. THE HIGHEST
CHANCES WILL AGAIN BE IN THE SOUTHEAST... BUT PRECIPITATION IS
EXPECTED TO BE MUCH MORE WIDESPREAD THAN THE PRECIPITATION
TONIGHT/FRIDAY.
