1125 AM CDT FRI JUL 9 2004

ZONES AND OTHER PRODUCTS BEING DELAYED BY GFE/AWIPS PROBLEMS...WILL
GET THEM OUT ASAP.

ANOTHER DAY...ANOTHER CONVECTIVE COMPLEX MOVING ACROSS PARTS OF THE
AREA. CURRENT COMPLEX HAS BEEN WEAKENING BUT THIS TREND SHOULD
CHANGE OVER THE NEXT COUPLE HOURS AS NEW STORMS ORGANIZE FURTHER
SOUTH ALONG THE OUTFLOW BOUNDARY MUCH AS WHAT OCCURRED THURSDAY.
INSTABILITY IS HIGH AGAIN TODAY WITH FAIRLY WEAK FLOW ALOFT SO PULSE
TYPE SEVERE STORMS SEEM LIKELY AGAIN. POTENTIAL ALSO EXISTS FOR
HEAVY RAIN GIVEN THE SLOW MOVEMENT OF THE STORMS. IT WILL BE
INTERESTING TO SEE HOW THE OLD MESOSCALE VORTICITY CENTER NEAR THE
OKLAHOMA/ARKANSAS/MISSOURI BORDER REGION INTERACTS WITH THE CURRENT
STORMS.

WE ARE LIKELY TO SEE ONE OR TWO MESOSCALE VORTICITY CENTERS
SOMEWHERE OVER THE AREA TONIGHT. JUST LIKE LAST NIGHT...PERSISTENT
CONVECTIVE DEVELOPMENT MAY OCCUR NEAR THESE CENTERS OVERNIGHT
BRINGING A LOCALIZED THREAT OF HEAVY RAINFALL. JUST WHERE IS
ANYBODYS GUESS AT THIS POINT IN TIME.

ADJUSTED THE FIRST PERIOD OF THE FORECAST TO REFLECT CURRENT TRENDS
AND EXPECTATIONS. NEW HAZARDOUS WEATHER OUTLOOK TEXT AND GRAPHICS
HAVE BEEN SENT AND THE REST OF THE FORECAST PRODUCTS WILL BE OUT
SHORTLY.

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT

...SEVERE THUNDERSTORMS LIKELY THIS AFTERNOON...

A COMPLEX OF THUNDERSTORMS ENTERING NORTHEAST OKLAHOMA THIS MORNING
HAS BEEN GRADUALLY WEAKENING AS IT MOVES SOUTH. HOWEVER...
THUNDERSTORMS ARE EXPECTED TO RAPIDLY DEVELOP AND INTENSIFY BY EARLY
THIS AFTERNOON ALONG THE OUTFLOW BOUNDARY FROM THIS MORNINGS STORMS.

ABUNDANT SUNSHINE IS OCCURRING ACROSS MUCH OF EAST CENTRAL AND
SOUTHEAST OKLAHOMA AND THE AIRMASS IS ALREADY BECOMING EXTREMELY
UNSTABLE. THIS WILL ALLOW THE THUNDERSTORMS THAT DEVELOP EARLY THIS
AFTERNOON TO QUICKLY INTENSIFY TO SEVERE LEVELS. THE FLOW ALOFT
REMAINS RATHER WEAK BUT IS BEING ENHANCED BY A WEAK CIRCULATION
CENTER ALOFT LOCATED BETWEEN JOPLIN AND FAYETTEVILLE. THIS
CIRCULATION CENTER DEVELPED OUT OF THE THUNDERSTORM COMPLEX WHICH
MOVED ACROSS THE AREA THURSDAY AFTERNOON.

THE SLIGHTLY ENHANCED FLOW ALOFT WILL ALLOW FOR PERHAPS A MORE
ORGANIZED SEVERE WEATHER THREAT FOR A TIME THIS AFTERNOON ACROSS
PARTS OF EAST CENTRAL AND SOUTHEAST OKLAHOMA...ROUGHLY FROM ABOUT
INTERSTATE 40 SOUTH FOR ABOUT 50 MILES. FURTHER EAST IN
ARKANSAS...MORE CLOUD COVER WILL RESULT IN WEAKER INSTABILITY SO THE
SEVERE THREAT WILL BE SOMEWHAT LOWER IN THAT AREA.

DAMAGING WINDS OF UP TO 70 MILES AN HOUR AND HAIL UP TO QUARTER SIZE
WILL BE THE MAIN SEVERE WEATHER THREATS WITH THE STORMS THIS
AFTERNOON. VERY HEAVY RAINFALL WILL ALSO BE POSSIBLE WITH THE STORMS
GIVEN THE RELATIVE SLOW MOVEMENT EXPECTED.

THE THUNDERSTORMS ARE EXPECTED TO WEAKEN BY EARLY THIS EVENING WITH
THE LOSS OF SURFACE HEATING. ADDITIONAL THUNDERSTORMS MAY DEVELOP
OVERNIGHT NEAR THE WEAK CIRCULATION CENTER ALOFT BUT THESE STORMS
ARE NOT LIKELY TO BE SEVERE ALTHOUGH THEY MAY POSE A LOCALLY HEAVY
RAIN THREAT.

WARNING PROBABILITIES FOR SEVERE THUNDERSTORMS AND TORNADOES CAN BE
FOUND IN THE CURRENT HAZARDS SECTION AT: WWW.SRH.NOAA.GOV/TULSA.
GIVEN PROBABILITIES REPRESENT THE POTENTIAL FOR A WARNING TO BE
ISSUED AT YOUR LOCATION.

SPOTTER / EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION WILL LIKELY BE REQUIRED IN PARTS OF EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY
THERE WILL BE A SLIGHT CHANCE OF THUNDERSTORMS OVER THE
WEEKEND.
