330 AM CDT SAT JUL 22 2000

NEXT MCS IN THE SERIES CONTS TO MOVE SE ALONG THETA-E RIDGE ACROSS
CWA EARLY THIS MORNING. PREVIOUS FORECAST HAD GOOD HANDLE ON THIS.
TODAYS FORECAST WILL BE WEIGHTED HEAVILY ON PREVIOUS PACKAGE AND THE
LATEST RADAR AND SATELLITE TRENDS. OTHERWISE NOT MUCH TO CHANGE.
COULD SEE A SIMILAR SETUP TONIGHT...BUT TRAJECTORIES LOOK TO KEEP
THE NEXT ONE EVEN FARTHER WEST. UPPER RIDGE CONT TO BUILD NORTH
ACROSS ROCKIES WITH A MORE NORTH/SOUTH ORIENTED FLOW. ALTHOUGH
CHANCES GET LOWER AS WE GO THROUGH EXTENDED TIME FRAME WILL KEEP
POPS GOING THROUGH SUNDAY EVERYWHERE AS PER PREVIOUS FORECAST. WITH
TIME MEDIUM RANGE MODELS WANT TO BEGIN TO SHIFT THE RIDGE BACK EAST
INTO CENTRAL/SOUTHERN PLAINS WHICH WOULD MEAN RETURN TO HOT AND
DRIER CONDITIONS BY WEEKS END AND WILL TREND THAT WAY. HOPE TO SEE
NEWEST MRF BEFORE ISSUANCE TIME...OTHERWISE NO MAJOR CHANGES
ANTICIPATED TO EXTENDED.

THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE NORMAN OK
600 AM CDT SAT JUL 22 2000

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS EARLY THIS MORNING
ACROSS NORTH TEXAS AND SOUTHERN OKLAHOMA. THE SLIGHT RISK AREA IS
SOUTH OF A LINE FROM QUANAH TO VERNON...TO ARDMORE...TO ATOKA. THE
PRIMARY THREAT WILL BE DAMAGING WINDS.

DISCUSSION...SEVERE THUNDERSTORMS ARE CURRENTLY MOVING ACROSS
PORTIONS OF SOUTHERN OKLAHOMA AS PART OF A LARGE CONVECTIVE CLUSTER
OF STORMS. THE STRONGEST STORMS LIE ACROSS AN AREA FROM HUGHES TO
NORTHERN LOVE COUNTY. THIS AREA OF STORMS WILL CONTINUE MOVING SOUTH
AND EAST.

THE STORMS HAVE NOT MOVED INTO WESTERN NORTH TEXAS...HOWEVER THE
OUTFLOW FROM THE OVERNIGHT STORMS MAY YET PRODUCE A FEW STORMS THIS
MORNING.

OVERNIGHT...A COMPLEX OF STORMS MAY REFORM OVER THE HIGH PLAINS AND
MOVE SOUTHEAST. HOWEVER IT APPEARS AT THIS TIME THAT THE MAIN SEVERE
STORM RISK WILL BE ACROSS THE TEXAS AND OKLAHOMA PANHANDLES...AND
ANY STORMS THAT MOVE INTO FAR WESTERN OKLAHOMA OR FAR WESTERN NORTH
TEXAS WILL NOT BE SEVERE.
