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 THIS EVENING THROUGH
SATURDAY MORNING ACROSS PORTIONS OF CENTRAL... SOUTH CENTRAL... AND
SOUTHEAST OKLAHOMA.

LOCATION...
THE SLIGHT RISK AREA IS EAST OF A LINE FROM STILLWATER... TO
YUKON... TO DUNCAN OKLAHOMA... TO HENRIETTA TEXAS. THIS INCLUDES THE
OKLAHOMA CITY AREA.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE AFTER 4 PM.

IMPACTS...
WIND GUSTS TO 70 MPH WILL BE THE MAIN CONCERN. HAIL UP TO ONE INCH
IN DIAMETER ALSO WILL BE POSSIBLE.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD BE PREPARED FOR SEVERE WEATHER OPERATIONS TONIGHT
INTO EARLY SATURDAY MORNING.

DISCUSSION...
AN UPPER LEVEL STORM SYSTEM IN THE WESTERN UNITED STATES WILL RESULT
IN A CONTINUATION OF GUSTY SOUTH WINDS TODAY... TRANSPORTING
UNSEASONABLY WARM AND MOIST AIR FROM THE GULF OF MEXICO NORTHWARD
INTO THE REGION. THIS WILL LEAD TO A CHANCE OF THUNDERSTORMS FROM
LATE TODAY THROUGH EARLY SATURDAY MORNING... AS THE UPPER LEVEL
STORM SYSTEM AND A SURFACE COLD FRONT MOVE THROUGH THE SOUTHERN
PLAINS.

SCATTERED THUNDERSTORMS WILL BE POSSIBLE THIS EVENING IN THE AREA
EAST OF A DRYLINE THAT WILL DEVELOP OVER WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS THIS AFTERNOON. THE UPPER LEVEL STORM SYSTEM
WILL APPROACH THE REGION... INCREASING LIFT OVER THE AREA THIS
EVENING. STRONG WIND SHEAR AND MODERATE INSTABILITY ARE EXPECTED TO
DEVELOP OVER THE AREA... WHICH COULD LEAD TO THE DEVELOPMENT OF A
FEW SEVERE STORMS. DAMAGING WINDS AND HAIL TO THE SIZE OF QUARTERS
WILL BE THE MAIN CONCERN WITH THESE SEVERE STORMS.

THUNDERSTORMS ARE THEN EXPECTED TO DEVELOP ALONG A COLD FRONT LATE
TONIGHT INTO EARLY SATURDAY MORNING... AS THE FRONT QUICKLY MOVES
SOUTHEAST INTO CENTRAL AND SOUTH CENTRAL OKLAHOMA AND NORTH CENTRAL
TEXAS. THESE STORMS ARE LIKELY TO DEVELOP INTO ONE OR MORE LINES. A
FEW OF THE STORMS MAY BECOME SEVERE WITH STRONG WINDS THE MAIN
CONCERN.

PROBABILITY TABLE...
VALID THROUGH 700 AM CST SATURDAY DEC 27.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...90 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...40 PERCENT.

OTHER HAZARDOUS WEATHER...
AREAS OF FOG WILL CONTINUE TO AFFECT PORTIONS OF SOUTHERN AND
CENTRAL OKLAHOMA... AND WESTERN NORTH TEXAS THIS MORNING. ISOLATED
LOCATIONS OF DENSE FOG WILL BE POSSIBLE... SO DRIVERS NEED TO BE
CAUTIOUS AS VISIBILITIES MAY CHANGE RAPIDLY.

BREEZY SOUTH WINDS WILL COMBINE WITH VERY WARM TEMPERATURES AND DRY
VEGETATION TO ELEVATE THE WILDFIRE POTENTIAL ACROSS FAR WESTERN
OKLAHOMA AND WESTERN NORTH TEXAS THIS AFTERNOON. SOUTH TO SOUTHWEST
WINDS MAY EXCEED 30 MPH... WITH GUSTS IN EXCESS OF 40 MPH
POSSIBLE... ESPECIALLY OVER WESTERN OKLAHOMA THIS AFTERNOON.

THE RAIN MAY MIX WITH OR CHANGE OVER TO SNOW LATE TONIGHT INTO
SATURDAY MORNING ACROSS PORTIONS OF NORTHWEST OKLAHOMA. SOME
ACCUMULATING SNOWFALL MAY OCCUR... WHICH COULD CAUSE TRAVEL PROBLEMS
IN A FEW LOCATIONS... BUT NO SIGNIFICANT AMOUNTS ARE EXPECTED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY...

THUNDERSTORM OUTLOOK...
THUNDERSTORMS MAY BE ONGOING SATURDAY MORNING ACROSS PORTIONS OF
SOUTHEAST AND SOUTH CENTRAL OKLAHOMA AS THE COLD FRONT CONTINUES TO
MOVE ACROSS THE REGION. A FEW SEVERE STORMS WILL REMAIN POSSIBLE...
WITH STRONG WIND GUSTS THE MAIN CONCERN. THE STORMS ARE EXPECTED TO
EXIT THE AREA BY MID-DAY.

OTHER HAZARDOUS WEATHER...
RAIN MAY CONTINUE TO MIX WITH OR CHANGE OVER TO SNOW ACROSS PORTIONS
OF NORTHERN OKLAHOMA SATURDAY MORNING. ACCUMULATIONS UP TO AROUND A
HALF AN INCH ARE POSSIBLE. THE SNOW MAY CAUSE A FEW SLICK SPOTS
SATURDAY MORNING. HOWEVER... THE SNOW LIKELY WILL NOT LINGER LONG AS
TEMPERATURES SATURDAY AFTERNOON ARE EXPECTED TO WARM ABOVE FREEZING.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT NOON
TODAY.
