AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
310 PM CDT SAT 14 2002

FIRST PERIOD POPS WILL BE HEAVILY DEPENDENT ON SATELLITE AND RADAR
TRENDS TOWARD ISSUANCE TIME. THERE WILL BE TWO MAIN AREAS/FEATURES
TO WATCH. ONE IS ACROSS NORTH CENTRAL ZONES NEAR VORTEX CENTER.
MOSTLY INDUCED BY COLD CORE TEMPS...THIS COULD POSE A PROBLEM FOR
FLOODING...AS A FAIRLY LARGE AREA OF NORTH CENTRAL OKLAHOMA RECEIVED
BETWEEN 2 AND 4+ INCHES OF RAIN EARLY THIS MORNING. A FLASH FLOOD
WATCH MAY BE NEEDED IF ACTIVITY BECOMES ORGANIZED...BUT HEAVIEST
RAIN STILL EXPECTED FURTHER SOUTH.

SECOND IS WEAK SURFACE BOUNDARY...WHICH IS BECOMING BETTER DEFINED
ACROSS WEST CENTRAL OKLAHOMA. GIVEN DECENT WARM-UP AHEAD OF
BOUNDARY...ALONG WITH WEAKLY CAPPED ENVIRONMENT...THIS FEATURE
EXPECTED TO LIGHT UP AND PROVIDE MUCH OF CENTRAL/SOUTHERN OKLAHOMA
AND WESTERN NORTH TEXAS TEXAS WITH SHOWERS AND THUNDERSTORMS. IF
LINE CAN DEVELOP AND FILL IN...TO WOULD LIKELY MOVE INTO CENTRAL
PARTS OF OKLAHOMA LATE THIS AFTERNOON THROUGH EARLY EVENING...THEN
SHIFT SOUTH AND EAST. MAIN CONCERN WITH ANY ACTIVITY WILL BE
LIGHTNING AND HEAVY RAINFALL. LINGERING (LIGHT) SHOWERS WILL LIKELY
BE SEEN ACROSS CENTRAL AND SOUTHERN AREAS AFTER THIS LINE MOVES
THROUGH.

LOW POPS WILL NEED TO BE KEPT ACROSS EASTERN/SOUTHERN PORTIONS OF
FORECAST AREA ON SUNDAY AS UPPER VORT CENTR IS SLOW TO MOVE OUT AND
SURFACE FRONT BEGINS TO STALL. THEN...IT APPEARS THAT THERE WILL BE
A COUPLE OF DRY SEASONABLE DAYS UNTIL MID WEEK...WHEN MEDIUM RANGE
MODELS WANT TO BRING IN ANOTHER SUBSTANTIAL FRONT. DYNAMIC SUPPORT
WILL BE THERE FOR POPS TO BE CONTINUED. WILL LEAVE POPS IN THE
WEDNESDAY NIGHT AND THURSDAY TIME FRAME FOR NOW. ANOTHER FRONT IS
PROGD AGAIN FOR THE WEEKEND.
