EASTERN OKLAHOMA/NORTHWEST ARKANSAS HAZARDOUS WEATHER OUTLOOK...UPDATED
NATIONAL WEATHER SERVICE TULSA OK
845 PM CDT SAT AUG 24 2002

...CHANCE OF SEVERE THUNDERSTORMS TONIGHT...

A STATIONARY SURFACE BOUNDARY EXTENDED FROM NEAR OKLAHOMA CITY TO
JUST NORTH OF MCALESTER TO SOUTH OF FORT SMITH. SCATTERED
THUNDERSTORMS WERE BEGINNING TO DEVELOP NEAR THE BOUNDARY ACROSS
WESTERN AND CENTRAL OKLAHOMA THIS EVENING. SCATTERED TO NUMEROUS
THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR THE BOUNDARY ACROSS
EASTERN OKLAHOMA LATER THIS EVENING AS LIFTING INCREASES AHEAD OF AN
UPPER LEVEL SYSTEM.

A FEW OF THE THUNDERSTORMS...ESPECIALLY IN AREAS SOUTH OF A LINE
FROM TULSA TO FORT SMITH...COULD BECOME SEVERE TONIGHT AND PRODUCE
LARGE HAIL AND DAMAGING WINDS. THE AIRMASS IS SLIGHTLY MORE STABLE
IN AREAS NORTH OF A TULSA TO FORT SMITH LINE...SO LESS INTENSE
THUNDERSTORMS ARE FORECAST IN THESE AREAS.

.SPOTTER ACTIVATION...
SPOTTER ACTIVATION MAY BE NEEDED BY MIDNIGHT ACROSS PARTS OF
EASTERN OKLAHOMA AND WESTERN ARKANSAS.

.DISCUSSION...
CONVECTIVE DEVELOPMENT IS EXPECTED BY MIDNIGHT AS WARM ADVECTION
LIFT INCREASES ALONG AND NORTH OF THE SURFACE BOUNDARY. ELEVATED
INSTABILITIES OF 2500 J/KG AND MID LEVEL NORTHWESTERLY WINDS
INCREASING TO OVER 30 KNOTS SUPPORT THE POTENTIAL FOR SEVERE
THUNDERSTORMS. MARGINALLY SEVERE HAIL WILL BE POSSIBLE WITH SOME OF
THE THUNDERSTORMS...BUT THE PRIMARY SEVERE WEATHER THREAT WILL BE
DAMAGING STRAIGHT LINE WINDS.

STRONG DIVERGENCE IN THE LEFT FRONT QUADRANT OF AN 80 KNOT UPPER JET
WILL MOVE ACROSS EXTREME NORTHERN OKLAHOMA AND THE NORTHWEST CORNER
OF ARKANSAS TONIGHT. THIS UPPER SUPPORT IS NORMALLY FAVORABLE FOR
SEVERE THUNDERSTORM DEVELOPMENT...BUT INSTABILITY IS LOWER IN THIS
AREA SINCE EARLIER CONVECTION HAD A STABILIZING EFFECT. ISOLATED
SEVERE THUNDERSTORMS WILL STILL BE POSSIBLE...BUT THE MORE ORGANIZED
ACTIVITY IS EXPECTED TO REMAIN FURTHER SOUTH NEAR THE SURFACE
BOUNDARY.

RISK TABLE
VALID THROUGH 1200 UTC SUNDAY

AREA 1...ALONG AND SOUTH OF A LINE FROM TULSA TO FORT SMITH
THUNDERSTORM PROBABILITY...90
SEVERE PROBABILITY IF STORMS OCCUR...50
SIGNIFICANT SEVERE PROBABILITY IF STORMS OCCUR...30

AREA 2...NORTH OF A LINE FROM TULSA TO FORT SMITH
THUNDERSTORM PROBABILITY...100
SEVERE PROBABILITY IF STORMS OCCUR...20
SIGNIFICANT SEVERE PROBABILITY IF STORMS OCCUR...10

RISK AREAS DEFINE THE GREATEST RISK. PROBABILITIES ARE IN PERCENT.
SIGNIFICANT SEVERE IS DEFINED AS F1 OR GREATER WIND/TORNADO DAMAGE
AND/OR GOLFBALL SIZE HAIL OR LARGER.

.OTHER HAZARDS...
LOCALLY HEAVY RAINFALL IS POSSIBLE TONIGHT AND EARLY SUNDAY MORNING
AS SEVERAL ROUNDS OF THUNDERSTORMS AFFECT THE AREA.
