THE FRONT THAT HAS BEEN ACROSS NORTHERN OK AND SOUTHERN KS WILL BE
THERE AGAIN TODAY PROVIDING THE SURFACE FOCUS FOR SCATTERED SHOWERS
AND THUNDERSTORMS. LITTLE CHANGE IS EXPECTED IN THE UPPER TROUGH
PATTERN OVER THE CENTRAL AND SOUTHERN PLAINS UNTIL SATURDAY
AFTERNOON. THE LOW OVER NE SHOULD MOVE INTO THE UPPER MIDWEST
ALLOWING A MORE NORTHWEST FLOW PATTERN INTO OK AND HELPING DRIVE THE
FRONT TOWARD THE RED RIVER BY SATURDAY EVENING. THIS WILL SHIFT THE
FOCUS OF SHOWER/STORM DEVELOPMENT TO SOUTHERN OK SATURDAY AND
SATURDAY NIGHT. THE MEAGER SURFACE HIGH IS EXPECTED TO MOVE INTO
NORTHERN AND CENTRAL OK SUNDAY WITH A SLIGHT DECREASE IN

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE NORMAN OK
700 AM CDT FRI AUG 24 2001

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING ACROSS MUCH OF CENTRAL AND WESTERN OKLAHOMA... AND A PORTION
OF WESTERN NORTH TEXAS.  THE SLIGHT RISK AREA IS ALONG AND NORTH OF
A LINE ROUGHLY FROM SEYMOUR... TO WICHITA FALLS... TO PURCELL... TO
SEMINOLE.  THE PRIMARY SEVERE WEATHER THREATS WILL BE DAMAGING WIND
GUSTS AND LARGE HAIL. HEAVY RAINFALL WILL ALSO BE POSSIBLE...
ESPECIALLY LATER THIS EVENING AND OVERNIGHT.

A MID AND UPPER LEVEL STORM SYSTEM CENTERED NEAR THE KANSAS-NEBRASKA
BORDER EARLY THIS MORNING WILL MOVE SLOWLY EASTWARD THROUGH TODAY
AND TONIGHT.  BY THIS AFTERNOON... A WEAK SURFACE FRONT WILL BE
NEARLY STATIONARY ALONG THE KANSAS-OKLAHOMA BORDER... AND OTHER
RESIDUAL OUTFLOW BOUNDARIES FROM MORNING THUNDERSTORMS ARE LIKELY TO
PERSIST SOUTH OF THE FRONT ACROSS WESTERN AND NORTHERN OKLAHOMA.
CONSIDERABLE SUNSHINE TODAY ALONG AND SOUTH OF THE BOUNDARY WILL AID
THE DEVELOPMENT OF MODERATE TO STRONG INSTABILITY BY MID TO LATE
AFTERNOON ACROSS THE SLIGHT RISK AREA. IN ADDITION... A BAND OF
STRONGER MID LEVEL WINDS WILL EXIST OVER NORTHERN OKLAHOMA WHICH
WILL ACT TO INCREASE VERTICAL WIND SHEAR ACROSS THE REGION.

THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR THE FRONT AND RESIDUAL
OUTFLOW BOUNDARIES THIS AFTERNOON AND EVENING.  SOME OF THE STORMS
ARE EXPECTED TO BECOME SEVERE WITH A THREAT OF DAMAGING WIND GUSTS
AND LARGE HAIL. AS THE LOW LEVEL JET INCREASES THIS EVENING AND
OVERNIGHT... STORMS MAY CONTINUE TO DEVELOP WITH AN INCREASING
THREAT FOR HEAVY RAINFALL.

EMERGENCY MANAGERS AND SPOTTER GROUPS IN THE SLIGHT RISK AREA SHOULD
BE PREPARED FOR POSSIBLE ACTIVATION THIS AFTERNOON... AND CONTINUING
AT LEAST THROUGH LATE EVENING.
