NWS Norman, OK wrote its last area forecast discussion before this flash flood warning went out at Oct 24, 3:45 PM CDT, 5 hours 35 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
345 PM CDT TUE OCT 24 2000

MORNING ANALYSIS HAS UPPER LOW OVER SOUTH CENTRAL UTAH WITH BEST
HEIGHT FALLS TO THE EAST AND NORTH.  LATEST AVN AND ETA MOVE LOW
DURING NEXT 36 HOURS NORTHEAST INTO NORTHERN PLAINS.  AS THIS
HAPPENS...FORECAST AREA WILL BE LOCATED UNDER RR PART OF UPPER JET
LATE TONIGHT INTO WEDNESDAY.

EXPECT ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS BECOMING MORE
NUMEROUS ACROSS THE WESTERN PART OF THE FORECAST AREA FROM MID
EVENING ON AND THEN SPREADING INTO EASTERN PARTS OF THE FORECAST
AREA FROM MIDNIGHT ON.  PW'S ARE STILL AOA 1.25 SO POTENTIAL FOR
LOCALLY HEAVY RAIN WILL BE POSSIBLE.  HOWEVER...STILL NO MAIN FOCUS
TO TRY AND FIGURE LOCATION WHERE HEAVIEST RAIN MAY FALL.  SEEMS LIKE
BETTER CHANCE WILL BE FARTHER WEST CLOSER TO THE LEE TROUGH.

ON WEDNESDAY AS SYSTEM CONTINUES TO MOVE NORTH AND EAST...MORE
NUMEROUS SHOWERS AND THUNDERSTORMS WILL BE LOCATED OVER EASTERN
PARTS OF THE FORECAST AREA.  AGAIN LOCALLY HEAVY RAINFALL WILL
BE POSSIBLE WHERE STRONGER THUNDERSTORMS CAN TRAIN.  BEST CHANCE
FOR CONTINUED SHOWERS AND THUNDERSTORMS WEDNESDAY EVENING WILL
BE ACROSS NORTHEAST PART OF FORECAST AREA.

DIFFERENCES IN MODELS FOR THURSDAY AS AVN DEVELOPS WAVE SOUTHWEST
OF AREA THEN MOVES IT NORTHEAST DURING THE DAY.  ETA NOT AS BULLISH
WITH THIS FEATURE.  WILL TREND MORE WITH AN ETA SOLUTION ON THURSDAY.

IN THE EXTENDED PERIOD...MRF NOW HAS ANOTHER LOW MOVING OUT OF SOUTHWEST
LATE FRIDAY INTO SATURDAY.  ECMWF SOMEWHAT SIMILAR TO THIS BUT TAKES
LOW FARTHER NORTH.  WILL ADD CHANCE OF RAIN INTO FORECAST FOR SATURDAY
WITH LINGERING CHANCES ACROSS NORTHCENTRAL SECTIONS SUNDAY.
