906 AM CDT SUN APR 26 2015

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHERN...
WESTERN...CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH
TEXAS.

.DAY ONE...TODAY AND TONIGHT...

.THUNDERSTORMS...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MOST OF
SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK INCLUDES ALL AREAS ALONG AND SOUTH OF A LINE FROM
ARNETT... TO NORMAN... TO HOLDENVILLE OKLAHOMA. THIS INCLUDES ALL
OF WESTERN NORTH TEXAS.

TIMING...
4 PM TO MIDNIGHT

IMPACTS...
THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING DESTRUCTIVE
HAIL TO THE SIZE OF BASEBALLS AND 60 TO 70 MPH DAMAGING WIND
GUSTS. A TORNADO OR TWO WILL ALSO BE POSSIBLE... ESPECIALLY
ACROSS PORTIONS OF NORTHERN TEXAS AND SOUTHWESTERN OKLAHOMA.
ADDITIONALLY... LOCALIZED HEAVY RAINFALL MAY LEAD TO FLASH
FLOODING.

DISCUSSION...
A FRONTAL BOUNDARY WILL STALL ALONG THE NEAR THE RED RIVER BY
EARLY AFTERNOON AS A DEEPENING AREA OF LOW PRESSURE ACROSS WEST
TEXAS WILL ALLOW A DRYLINE TO MIX EASTWARD... FROM SOUTHWESTERN
OKLAHOMA INTO CENTRAL TEXAS THROUGH THE MID TO LATE AFTERNOON
HOURS. SOUTHEAST WINDS AHEAD OF THE DRYLINE WILL ALLOW CONTINUAL
TRANSPORT OF ABUNDANT LOW LEVEL MOISTURE... WHICH WILL COMBINE
WITH SUFFICIENT HEATING FOR THE PRODUCTION OF MODERATE
INSTABILITY. MEANWHILE... A STRONG UPPER LEVEL STORM SYSTEM WILL
MOVE INTO THE UNSTABLE AIRMASS THROUGH THE AFTERNOON... RESULTING
IN RAPID THUNDERSTORM DEVELOPMENT ALONG BOTH THE DRYLINE AND THE
STALLED FRONT... WHICH MAY BEGIN A SLOW RETREAT NORTHWARD LATE IN
THE DAY. INITIAL STORMS WILL LIKELY BECOME SEVERE RAPIDLY. COLD
TEMPERATURES ALOFT WILL PROMOTE LARGE HAIL GROWTH... AND SHEAR
WILL SUPPORT HAIL TO THE SIZE OF BASEBALLS IN THE STRONGEST
STORMS. THIS POTENTIAL WILL BE GREATEST ACROSS NORTHERN TEXAS INTO
SOUTHWESTERN AND FAR SOUTHERN OKLAHOMA... AS AN AREA OF BACKED
SURFACE WINDS DEVELOPS DURING THE LATE AFTERNOON AND EARLY
EVENING.

ONE OR MORE STORM CLUSTERS MAY DEVELOP DURING THE EVENING AND
OVERNIGHT HOURS. WITH ADEQUATE INSTABILITY AND FAVORABLE WIND
PROFILES... SEVERE THUNDERSTORM POTENTIAL IS LIKELY TO LINGER
INTO THE EARLY OVERNIGHT... WITH THE MAIN CONCERN BEING LARGE
HAIL AND STRONG WIND GUSTS. HEAVY RAINFALL WILL LIKELY ACCOMPANY
SOME OF THE STORMS... AND AREAS THAT RECEIVE PROLONGED RAINFALL
WITH SEVERAL ROUNDS OF STORMS WILL LIKELY SEE FLOODING.

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

.THUNDERSTORMS...
THE THREAT OF SEVERE STORMS SHOULD DIMINISH BY EARLY MONDAY...
BUT A FEW STRONG STORMS WILL REMAIN POSSIBLE... WITH HAIL AND
GUSTY WINDS THE PRIMARY CONCERNS. RAIN IS LIKELY TO LINGER INTO
AT LEAST TUESDAY MORNING... BEFORE GRADUALLY WINDING DOWN DURING
THE DAY. THE PRIMARY CONCERN MONDAY AND TUESDAY WILL BE THE EVER
INCREASING FLOOD POTENTIAL DUE TO PROLONGED HEAVY RAINFALL. AT
THIS TIME... AREAS OF WEST CENTRAL INTO CENTRAL... AND SOUTHERN
OKLAHOMA... APPEAR TO HAVE THE GREATEST CHANCES FOR FLASH
FLOODING AND POSSIBLY RIVER FLOODING. IF MODELS CONTINUE TO
DEPICT HEAVY RAINFALL IN THESE AREAS...A FLOOD WATCH MAY BECOME
NECESSARY.

THUNDERSTORM CHANCES AS WELL AS SEVERE WEATHER POTENTIAL
INCREASE THIS EVENING ACROSS EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS.

A FRONTAL BOUNDARY MOVING THROUGH THE REGION THIS MORNING IS
EXPECTED TO BECOME NEARLY STATIONARY NEAR THE RED RIVER THIS
AFTERNOON AS AN UPPER LEVEL LOW PRESSURE SYSTEM APPROACHES THE
SOUTHERN PLAINS. THUNDERSTORMS ARE FORECAST TO DEVELOP THIS
AFTERNOON OVER WESTERN OKLAHOMA AS INSTABILITY AHEAD OF THE UPPER

450 AM CDT SUN APR 26 2015

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHERN...
WESTERN...CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH
TEXAS.

.DAY ONE...TODAY AND TONIGHT...

.THUNDERSTORMS...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MOST OF
OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK INCLUDES ALL AREAS ALONG AND SOUTH OF A LINE
FROM GAGE...TO WOODWARD...TO ENID AND BILLINGS OKLAHOMA. THIS
INCLUDES ALL OF WESTERN NORTH TEXAS.

TIMING...
4 PM TO 2 AM

IMPACTS...
THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING DESTRUCTIVE
HAIL TO THE SIZE OF BASEBALLS...AND 60 TO 70 MPH WIND GUSTS. A
TORNADO OR TWO WILL ALSO BE POSSIBLE...ESPECIALLY ACROSS PARTS
OF SOUTHWESTERN AND SOUTH CENTRAL OKLAHOMA...INTO NORTH TEXAS.
LOCALLY HEAVY RAINFALL WITH SOME OF THE STORMS MAY ALSO LEAD
TO FLASH FLOODING IN SOME AREAS.

DISCUSSION...
A FRONTAL BOUNDARY IS EXPECTED TO STALL ALONG THE RED RIVER BY
EARLY AFTERNOON. MEANWHILE...A DEEPENING AREA OF LOW PRESSURE
ACROSS WEST TEXAS WILL ALLOW A DRYLINE TO MIX EASTWARD...FROM
SOUTHWESTERN OKLAHOMA DOWN INTO CENTRAL TEXAS DURING THE MID TO
LATE AFTERNOON HOURS. WITH SOUTHEAST WINDS AHEAD OF THE DRYLINE...
ABUNDANT LOW LEVEL MOISTURE AND DAYTIME HEATING WILL PROMOTE
MODERATE INSTABILITY. A STRONG UPPER LEVEL STORM SYSTEM WILL MOVE
INTO THIS UNSTABLE AIRMASS THROUGH THE AFTERNOON HOURS...RESULTING
IN RAPID THUNDERSTORM DEVELOPMENT ALONG BOTH THE DRYLINE AND THE
STALLED FRONT...WHICH MAY BEGIN A SLOW RETREAT NORTHWARD LATE IN
THE DAY. GIVEN VERY FAVORABLE WIND FIELDS AND MODERATE
INSTABILITY...STORMS SHOULD BECOME SEVERE RAPIDLY. COLD TEMPERATURES
ALOFT WILL PROMOTE LARGE HAIL GROWTH...AND HAIL UP TO BASEBALL SIZE
MAY ACCOMPANY THE STRONGEST STORMS. THERE WILL ALSO BE THE POTENTIAL
FOR TORNADOES WITH THE STRONGER STORMS. THIS POTENTIAL WILL BE
GREATEST FROM SOUTHWESTERN THROUGH SOUTH CENTRAL OKLAHOMA...DOWN
INTO NORTH TEXAS...AS AN AREA OF BACKED SURFACE WINDS DEVELOPS
DURING THE LATE AFTERNOON AND EARLY EVENING.

ONE OR MORE STORM CLUSTERS MAY DEVELOP DURING THE EVENING AND
OVERNIGHT HOURS...AS THUNDERSTORM OUTFLOWS MERGE. WITH ADEQUATE
INSTABILITY AND FAVORABLE WIND PROFILES...SEVERE THUNDERSTORM
POTENTIAL IS LIKELY TO LINGER INTO THE OVERNIGHT HOURS...WITH
THE MAIN CONCERN BEING LARGE HAIL AND A FEW STRONG WIND GUSTS.
HEAVY RAINFALL WILL LIKELY ACCOMPANY SOME OF THE STORMS...AND
AREAS THAT RECEIVE PROLONGED RAINFALL WITH SEVERAL ROUNDS OF
STORMS MAY SEE LOCALIZED FLOODING.

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

.THUNDERSTORMS...
THE THREAT OF SEVERE STORMS SHOULD DIMINISH BY EARLY MONDAY...BUT
A FEW STRONG STORMS WILL REMAIN POSSIBLE...WITH HAIL AND GUSTY
WINDS THE PRIMARY CONCERNS. RAIN IS LIKELY TO LINGER INTO AT LEAST
TUESDAY MORNING...BEFORE GRADUALLY WINDING DOWN DURING THE DAY
TUESDAY. THE PRIMARY CONCERN MONDAY AND TUESDAY WILL BE INCREASED
FLOOD POTENTIAL DUE TO PROLONGED HEAVY RAINFALL. AT THIS TIME...AREAS
OF WEST CENTRAL INTO CENTRAL...AND SOUTHERN OKLAHOMA...APPEAR TO HAVE
THE GREATEST CHANCES FOR FLASH FLOODING AND POSSIBLY RIVER FLOODING.
IF MODELS CONTINUE TO DEPICT HEAVY RAINFALL IN THESE AREAS...A FLOOD
WATCH MAY BECOME NECESSARY.
