1055 AM CDT SAT AUG 10 2002

15Z SURFACE ANALYSIS IS A CHALLENGE TO UNTANGLE...HOWEVER
SATELLITE/RADAR TRENDS SHED SOME LIGHT ON PLACEMENT OF SMALL SCALE
BOUNDARIES.  WEST TEXAS MCS HAS PLACED A BOUNDARY ACROSS WESTERN
OKLAHOMA WITH ANOTHER BOUNDARY APPARENT ALONG THE RED RIVER VALLEY
INTO EASTERN OKLAHOMA PER VIS SATELLITE IMAGERY.  ONGOING CONVECTION
IN EASTERN OKLAHOMA APPEARS TO BE ORIENTED ALONG THIS FEATURE.  LOW
LEVEL MOISTURE HAS MADE A NOTICEABLE RETURN ACROSS THE AREA WITH
24HR DEW POINT RISES AOA 10 DEG F IN MANY LOCALES.

12Z UPPER AIR ANALYSIS SHOWS MID LEVEL TROUGH AXIS HANGING BACK INTO
WESTERN OKLAHOMA WITH APPARENT MESOSCALE CONVECTIVE VORTEX SITUATED
ACROSS SW KANSAS ON TAIL END OF LARGE SCALE TROUGH AXIS.  THIS
FEATURE WILL PROGRESS SLOWLY EASTWARD TODAY AS RIGHT REAR QUADRANT
OF UPPER JET ALSO MOVES ACROSS THE AREA TO PROVIDE UPPER LEVEL
SUPPORT FOR AFTERNOON THUNDERSTORM DEVELOPMENT.  SEVERE POTENTIAL
QUESTIONABLE GIVEN VERY WEAK WINDS IN THE 800-600MB LEVEL...HOWEVER
ADEQUATE SURFACE HEATING AND ABUNDANT LOW LEVEL MOISTURE WILL YIELD
ADEQUATE SURFACE BASED CAPE FOR POTENTIAL PULSE SEVERE WITH WET
DOWNBURSTS BEING THE GREATEST THREAT.

UPDATE WISE...WILL TREND POPS UP AREAWIDE WITH HIGHEST POPS ALONG
SURFACE BOUNDARY WHERE CURRENT CONVECTION CONTINUES TO DEVELOP.
TEMPS WILL BE A LAST MINUTE ADJUSTMENT...BUT DON/T EXPECT TOO MUCH
CHANGE.

FORECAST ID= 07

NATIONAL WEATHER SERVICE TULSA OK
100 PM CDT SAT AUG 10 2002

...ISOLATED SEVERE THUNDERSTORMS POSSIBLE TODAY ACROSS EASTERN
   OKLAHOMA AND NORTHWEST ARKANSAS...

SCATTERED THUNDERSTORMS WITH HEAVY RAINFALL WILL BE POSSIBLE ACROSS
THE ENTIRE OUTLOOK AREA THROUGH SATURDAY NIGHT...WITH A GENERAL
DECREASE IN THUNDERSTORM ACTIVITY EXPECTED AFTER SUNSET.  LOCATIONS
SOUTHEAST OF A LINE FROM FAYETTEVILLE TO MCALESTER WILL HAVE THE
HIGHEST RAIN CHANCES...HOWEVER AN APPROACHING UPPER DISTURBANCE WILL
HELP IGNITE ADDITIONAL THUNDERSTORMS ACROSS NORTHERN OKLAHOMA BY
LATE AFTERNOON.  THE SEVERE WEATHER THREAT IS EXPECTED TO BE VERY
ISOLATED DURING THE AFTERNOON HOURS.

.SPOTTER ACTIVATION...
SPOTTER ACTIVATION IS NOT ANTICIPATED DUE TO THE ISOLATED SEVERE
WEATHER THREAT.

.DISCUSSION...
NUMEROUS SURFACE BOUNDARIES ARE LOCATED ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS THIS AFTERNOON PROVIDING A FOCUS FOR THUNDERSTORM
DEVELOPMENT.  A SMALL SCALE UPPER DISTURBANCE WILL ALSO APPROACH THE
AREA BY LATE AFTERNOON PROVIDING ADDITIONAL UPPER SUPPORT FOR
THUNDERSTORM DEVELOPMENT.  WEAK WINDS ALOFT WILL LIMIT THE SEVERE
WEATHER THREAT...HOWEVER STRONG STRAIGHT LINE WINDS WILL BE POSSIBLE
WITH ANY COLLAPSING THUNDERSTORM.  VERY HEAVY RAINFALL WILL ALSO
ACCOMPANY THE STORMS WITH FLOODING OF LOW LYING AREAS POSSIBLE.
