Area forecast discussion, Jun 9, 3:49 PM CDT, 5 hours 7 minutes before
AREA FORECAST DISCUSSION...CORRECTED FFA AREA NATIONAL WEATHER SERVICE NORMAN OK 330 PM CDT MON JUN 9 1997 MAIN FORECAST PROBLEM THIS AFTERNOON IS PROBABILITY OF HEAVY RAIN OVER NORTHERN PTN FA. UPPER DIFFLUENCE AND DEEP RICH MOISTURE ARE IN PLACE AS UPPER LOW OPENS UP AND LIFTS OUT OVER NRN OK TONIGHT. LIMITING FACTOR FOR FLASH FLOODING IS THAT THE GROUND IN MOST PLACES IS NOWHERE NEAR SATURATION...BUT SLOW-MOVING HEAVY THUNDERSTORMS UNDER THE DIFFLUENT AREA SHOULD REMEDY THAT QUICKLY. WILL GO WITH A FLASH FLOOD WATCH FOR ABOUT THE NORTHERN HALF OF FA TONIGHT. OTHERWISE TEMPS SIMILAR TO PREVIOUS FORECAST/GUIDANCE AND WINDS LIGHT THROUGH PD.
