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

.DAY ONE…TODAY AND TONIGHT…

THUNDERSTORM OUTLOOK…
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TONIGHT ACROSS
PORTIONS OF NORTHERN OKLAHOMA.

LOCATION…
THE SLIGHT RISK AREA IS ALONG AND NORTH OF A LINE FROM ARNETT TO
WEATHERFORD TO OKLAHOMA CITY TO SHAWNEE.

TIMING…
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM EARLY
THIS EVENING INTO FRIDAY MORNING.

IMPACTS…
HAIL TO THE SIZE OF GOLF BALLS AND WINDS IN EXCESS OF 60 MPH WILL BE
THE MAIN HAZARDS. LIGHT DAMAGE TO HOMES AND AUTOMOBILES MAY OCCUR
WITH LARGE HAIL…ALONG WITH DAMAGE TO TENDER VEGETATION. TREES AND
POWER LINES WILL BE SUSCEPTIBLE TO DAMAGE FROM WIND GUSTS.

RECOMMENDED ACTIONS…
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR SEVERE WEATHER OPERATIONS THIS EVENING
AND FRIDAY MORNING.

DISCUSSION…
A WARM FRONT WILL MOVE NORTHWARD TODAY…BRINGING RICH MOISTURE AND
UNUSUALLY WARM TEMPERATURES TO MUCH OF THE REGION. THIS FRONT WILL
STALL NEAR THE KANSAS OKLAHOMA BORDER LATE TODAY. AS WARM MOIST AIR
RIDES UP AND OVER THE STALLED FRONT…WIDESPREAD SHOWERS AND
THUNDERSTORMS ARE EXPECTED LATE TODAY INTO THE OVERNIGHT HOURS. THE
COMBINATION OF MODERATE INSTABILITY AND STRONG WINDS ALOFT WILL
FAVOR A FEW SEVERE STORMS…PARTICULARLY NORTH OF INTERSTATE 40 NEAR
THE FRONTAL BOUNDARY. LARGE HAIL TO THE SIZE OF GOLF BALLS AND
DAMAGING WINDS WILL BE THE PRIMARY THREATS…THOUGH SOME AREAS MAY
ALSO RECEIVE LOCALLY HEAVY RAINFALL IF STORMS CONTINUE TO DEVELOP
OVER THE SAME AREA. STORMS WILL LIKELY CONTINUE PAST MIDNIGHT AND
INTO EARLY FRIDAY…THOUGH THE SEVERE THREAT SHOULD GRADUALLY
DIMINISH THROUGH FRIDAY MORNING.

PROBABILITY TABLE…
VALID THROUGH 700 AM CDT FRIDAY OCT 12.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA…100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR…60 PERCENT.

OTHER HAZARDOUS WEATHER…
NONE.

.DAYS TWO THROUGH SEVEN…FRIDAY THROUGH WEDNESDAY…

THUNDERSTORM OUTLOOK…
SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN FRIDAY AND FRIDAY
NIGHT…MAINLY ACROSS NORTHWEST OKLAHOMA…AND ON SATURDAY ACROSS
MUCH OF OKLAHOMA AND NORTH TEXAS AS A DRYLINE PUSHES INTO CENTRAL
OKLAHOMA. LARGE DAMAGING HAIL AND DESTRUCTIVE WINDS WILL BE THE
PRIMARY THREATS. HOWEVER… LOW LEVEL WIND SHEAR WILL BE STRONG
ENOUGH FOR THE POTENTIAL OF ISOLATED TORNADOES. A COLD FRONT WILL
PUSH THROUGH THE AREA BY SUNDAY MORNING…BRINGING MILD AND DRY
WEATHER THROUGH THE MIDDLE OF NEXT WEEK.

PEOPLE WHO ARE TRAVELING THIS WEEKEND SHOULD CONTINUE TO MONITOR THE
FORECAST AS SEVERE WEATHER MAY IMPACT TRAVELERS ON FRIDAY AND
ESPECIALLY ON SATURDAY.

SOME LOCALLY HEAVY RAINFALL WILL BE POSSIBLE FRIDAY AND SATURDAY…
BUT STORMS WILL BE MOVING RELATIVELY FAST WHICH SHOULD LIMIT THE
POTENTIAL OF PROLONGED HEAVY RAINFALL.

OTHER HAZARDOUS WEATHER…
NONE.
