AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OKLAHOMA
952 PM CDT FRI JUN 20 2003

A LINE OF THUNDERSTORMS CONTINUES TO PUSH EAST ACROSS THE OKLAHOMA
AND TEXAS PANHANDLES AS AN UPPER LEVEL WAVE CONTINUES TO PUSH ACROSS
NEW MEXICO INTO THE PANHANDLE. HAVE RAISED POPS ACCORDING TO CURRENT
RADAR TRENDS...WITH THE GREATEST POPS ACROSS NORTHWEST OKLAHOMA
WHERE BETTER LIFT WILL BE LOCATED AS THE UPPER DISTURBANCE ROTATES
TO THE NORTHEAST. HAVE ALSO ADJUSTED SKY COVER AND TEMPS. WILL SEND
UPDATE SHORTLY.

MAXWELL

230 PM CDT FRI JUN 20 2003

ANOTHER COUPLE OF WAVES TO AFFECT THE AREA OVER THE NEXT 36HRS. THE
FIRST IS CURRENTLY AFFECTING PARTS OF THE AREA. WITH MULTIPLE SFC
BOUNDARIES AROUND AND ABUNDANT LOW LEVEL MOISTURE AND WARM AFTN
TEMPS WILL LIKELY SEE SCATTERED STORMS THIS AFTN WHICH WILL LINGER
INTO THE EARLY EVENING BEFORE DISSIPATING. AFTER SUNSET WILL SEE A
BREAK IN THE ACTION WITH NEXT WAVE MOVING OUT OF SOUTHERN ROCKIES
BRINGING ANOTHER ROUND OF ACTIVITY...ALREADY DEVELOPING IN HIGH
PLAINS...ACROSS THE AREA LATE TONIGHT AND SAT MORNING.

COULD SEE SOME AFTN STORMS FIRE AGAIN TO OUR WEST NEAR A DRY LINE
WHICH WILL SET UP ACROSS EASTERN TX PANHANDLE SAT AFTN AND THEN MAKE
A RUN INTO FAR WESTERN OKLAHOMA LATE. ALTHOUGH MID AND UPPER FLOW
WILL REMAIN RATHER WEAK..IT WILL BE STRONGER THAN LAST COUPLE OF
DAYS. SO WILL NOT RULE OUT SOME ISOLATED SEVERE SAT AFTN/EVENING.
ANOTHER REASON FOR MORE ISOLATED STORMS IS THAT MID LEVEL WARMING
WILL BE KICKING IN TO SHUT OFF ACTIVITY ACROSS AREA. SUNDAY THROUGH
AT LEAST MID WEEK LOOKS DRY WITH WARMER THAN NORMAL TEMPS.

LATEST GFS IS MUCH QUICKER WITH UPPER WAVE BRINGING SFC FRONT
THROUGH AREA EARLY WED...WHILE OTHER MED RANGE MODELS HOLD OFF ON
BRINGING FRONT INTO AREA UNTIL LATER ON THU INTO FRI. WITH 12Z GFS
BEING LATEST MODEL RUN WILL LEAN TOWARD ITS SOLUTION BUT WILL GO
SOMEWHAT SLOWER WITH FRONTAL PASSAGE AND WILL INTRO POPS FOR WED AND
LINGER SOME LOW POPS THROUGH FRI.
