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

.DAY ONE...THIS AFTERNOON AND TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
OVERNIGHT ACROSS MOST OF OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK INCLUDES ALL OF WESTERN NORTH TEXAS AND ALL BUT
EXTREME NORTHWEST OKLAHOMA.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM NOW
THROUGH THE OVERNIGHT HOURS. THE SEVERE WEATHER THREAT WILL END FROM
NORTHWEST TO SOUTHEAST THIS EVENING AND OVERNIGHT AS A COLD FRONT
MAKES ITS WAY OVER THE REGION.

IMPACTS...
SEVERE HAIL UP TO BASEBALL SIZE AND THUNDERSTORM WINDS UP TO 75 MPH
WILL BE POSSIBLE. ISOLATED TORNADOES ARE ALSO POSSIBLE...MAINLY
THROUGH MID-EVENING.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR SEVERE WEATHER OPERATIONS UNTIL EARLY
MONDAY MORNING.

DISCUSSION...
A COLD FRONT WAS LOCATED ACROSS WEST-CENTRAL AND NORTHWEST OKLAHOMA
LATE THIS AFTERNOON...WITH A STRONG UPPER-LEVEL STORM SYSTEM LOCATED
OVER THE SOUTHERN ROCKIES. STRONG AND SEVERE STORMS ARE EXPECTED TO
CONTINUE NEAR AND AHEAD OF THIS COLD FRONT AS IT MOVES SOUTHEAST
THROUGH TONIGHT. IN ADDITION TO THE COLD FRONT...A SHARPENING DRY
LINE WILL BE SEEN OVER FAR SOUTHWEST OKLAHOMA AND PORTIONS OF
WESTERN NORTH TEXAS THROUGH LATE EVENING...BEFORE BEING OVERTAKEN BY
THE COLD FRONT. WEAK TO MODERATE INSTABILITY WILL BE SEEN AHEAD OF
AND NEAR THESE FEATURES...AND WIND SHEAR WILL BE QUITE STRONG.

A LINE OF THUNDERSTORMS WILL DEVELOP AHEAD OF THE DRY LINE AND COLD
FRONT...AND CONSOLIDATE INTO A LARGE COMPLEX BY LATE EVENING OVER
CENTRAL AND SOUTHERN PORTIONS OF OKLAHOMA...AND WESTERN NORTH TEXAS.
SCATTERED SUPERCELL THUNDERSTORMS WILL OCCUR AT LEAST THROUGH
MID-EVENING...AND WITH THOSE SUPERCELLS...LARGE HAIL AND DAMAGING
WINDS WILL BE LIKELY. ISOLATED TORNADOES CANNOT BE RULED OUT THROUGH
MID-EVENING. THE MAIN SEVERE WEATHER CONCERN BY LATE EVENING AND
OVERNIGHT WILL BE DAMAGING STRAIGHT-LINE WINDS AS THE STORMS
ORGANIZED INTO A LARGE COMPLEX.

AS THE COLDER AND MORE STABLE AIR FILTERS INTO THE REGION BEHIND THE
COLD FRONT...THE SEVERE WEATHER RISK WILL DIMINISH.

PROBABILITY TABLE...
VALID THROUGH 700 AM CST MONDAY MAR 3.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...100 PERCENT.

OTHER HAZARDOUS WEATHER...
LOW HUMIDITY AND GUSTY SOUTHWEST WINDS WILL DEVELOP IN SOUTHWEST
OKLAHOMA AND WESTERN NORTH TEXAS TO THE WEST OF THE DRY LINE LATE
THIS AFTERNOON. THIS WILL CAUSE VERY HIGH TO EXTREME FIRE DANGER FOR
THOSE AREAS.

IN ADDITION...HEAVY RAINFALL WILL BE POSSIBLE. ALTHOUGH LOCALLY
HEAVY RAIN WILL BE POSSIBLE THROUGHOUT THE AREA...THE MOST LIKELY
AREA FOR EXCESSIVE RAIN OVERNIGHT WILL BE ACROSS FAR SOUTHEAST
OKLAHOMA WHERE 3 TO 4 INCHES OF RAIN WILL BE POSSIBLE.

VERY STRONG NORTH WINDS WITH GUSTS OF 40 TO 55 MPH ARE ALSO EXPECTED
BEHIND THE COLD FRONT OVERNIGHT. THESE STRONG WINDS WILL COMBINE
WITH SNOW SHOWERS TO CREATE HAZARDOUS REDUCTIONS IN VISIBILITY LATE
TONIGHT AND MUCH OF TOMORROW.

PLEASE REFER TO THE LATEST RED FLAG WARNING... FLASH FLOOD WATCH AND
SNOW AND BLOWING SNOW ADVISORIES FOR THE LATEST INFORMATION
REGARDING THESE HAZARDS.

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

THUNDERSTORM OUTLOOK...
NO THUNDERSTORMS ARE EXPECTED.

OTHER HAZARDOUS WEATHER...
RAIN WILL MIX WITH AND CHANGE TO SNOW OVERNIGHT AND LINGER THROUGH
MONDAY. ACCUMULATING SNOW IS POSSIBLE ACROSS MUCH OF THE AREA ON
MONDAY INTO MONDAY NIGHT WITH MANY AREAS RECEIVING AN INCH OR TWO.
ACCUMULATIONS OF UP TO THREE INCHES WILL BE POSSIBLE... MAINLY SOUTH
AND EAST OF INTERSTATE 44. ALONG WITH THE SNOW... STRONG NORTH WINDS
ARE EXPECTED TO CONTINUE THROUGH MUCH OF MONDAY. THE COMBINATION OF
STRONG WINDS AND SNOW WILL RESULT IN RESTRICTED VISIBILITIES AND
DANGEROUS DRIVING CONDITIONS. RESIDENTS SHOULD CONTINUE TO MONITOR
THE LATEST FORECASTS.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 7 AM
MONDAY.
