200 AM CDT MON APR 25 2011

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...REST OF TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK AREA IS SOUTHEAST OF A LINE FROM ARCHER CITY AND
ELECTRA TEXAS... TO HOBART... ELK CITY... FAIRVIEW... AND PONCA CITY
OKLAHOMA.

TIMING...
THE LIKELIHOOD OF SEVERE STORMS WILL INCREASE BETWEEN 3 AND 5 AM.

IMPACTS...
DAMAGE TO AUTOMOBILES...ROOFTOPS...AND VEGETATION FROM LARGE HAIL UP
TO TWO INCHES IN DIAMETER.

DAMAGING STRAIGHT LINE WINDS OF 65 MPH.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD REMAIN ALERT TO THE POSSIBILITY OF SEVERE STORMS
OCCURRING IN THE EARLY MORNING HOURS. THE GREATEST CHANCE OF STORMS
IS GENERALLY NORTH OF A LINE FROM HOBART TO OKLAHOMA CITY AND
CHANDLER.

DISCUSSION...
ALTHOUGH A SHALLOW LAYER OF COOL AND STABLE AIR WAS PRESENT NEAR THE
GROUND...THE AIR ALOFT WAS MUCH WARMER AND UNSTABLE THROUGHOUT THE
RISK AREA. MEANWHILE...A VIGOROUS UPPER LEVEL JET STREAM DISTURBANCE
WAS APPROACHING. THIS WILL BRING SUFFICIENT LIFT TO INITIATE STRONG
TO SEVERE THUNDERSTORMS IN THE RISK AREA. A GREATER CONCENTRATION OF
STORMS MAY OCCUR NORTH OF A WARM FRONT ALOFT...LOCATED FROM HOBART
TO OKLAHOMA CITY AND CHANDLER. MODERATE INSTABILITY AND STRONG WIND
SHEAR WILL LIKELY RESULT IN SEVERE STORMS. EXCEPT FOR LIGHT WINDS AT
THE GROUND...WINDS WILL BE VERY STRONG THROUGH THE ENTIRE DEPTH OF
THE ATMOSPHERE...WITH STRONG TURNING. THIS COULD RESULT IN ORGANIZED
TYPES OF STORMS...SUCH AS SUPERCELLS AND BOW ECHOES...THAT WOULD
CARRY A THREAT OF DAMAGING HAIL AND WINDS.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY APR 25.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...70 PERCENT.

OTHER HAZARDOUS WEATHER...
AREAS OF PERSISTENT AND HEAVY RAIN COULD LEAD TO SOME LOCALIZED
FLOODING OVERNIGHT...ESPECIALLY IF STORMS REACH THE AREAS EAST AND
SOUTH OF OKLAHOMA CITY THAT RECEIVED HEAVY RAIN ON SUNDAY.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...

THUNDERSTORM OUTLOOK...
SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN ON MONDAY... MAINLY IN
EASTERN PARTS OF THE AREA...AS THE UPPER LEVEL DISTURBANCE MOVES
OVER THE AREA AND THE FRONT PUSHES BACK SOUTHEASTWARD.  THERE WILL
LIKELY BE A BREAK IN THE ACTION MONDAY NIGHT... BEFORE THE THREAT OF
SEVERE STORMS RETURNS ON TUESDAY... MAINLY TO SOUTHEAST OKLAHOMA...
AS A STRONG UPPER DISTURBANCE MOVES FROM THE ROCKIES INTO THE
SOUTHERN PLAINS. STORMS ARE AGAIN EXPECTED TO DEVELOP IN THE
VICINITY OF THE COLD FRONT.

DRY WEATHER WILL RETURN WEDNESDAY AS THIS SYSTEM MOVES EAST OF THE
AREA AND THE FRONT PUSHES WELL SOUTH OF THE REGION. THE DRY WEATHER
WILL THEN PERSIST INTO THE EARLY PART OF THE WEEKEND.

OTHER HAZARDOUS WEATHER...
ON MONDAY... A DRYLINE OR PACIFIC COLD FRONT IS FORECAST TO SPREAD
MUCH DRIER AIR INTO WESTERN NORTH TEXAS. THE POSSIBILITY OF
WILDFIRES WILL BE INCREASED IF THIS HAPPENS.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY 5 AM
MONDAY.
