AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1056 PM CDT FRI APR 24 2009

.AVIATION...
BRISK SOUTH WINDS THROUGH SATURDAY WILL CONTINUE TO PULL MORE GULF
MOISTURE NORTHWARD INTO THE AREA... RESULTING IN MVFR... WITH
OCCASIONAL IFR... CEILINGS ACROSS ALL BUT THE NW OK TERMINALS
LATE TONIGHT AND CONTINUING INTO MUCH OF SATURDAY. A COLD FRONT
MOVING INTO NORTHWEST OKLAHOMA LATE SATURDAY AFTERNOON MAY RESULT
IN A FEW SHOWERS AND THUNDERSTORMS ACROSS NORTHERN OKLAHOMA
SATURDAY NIGHT.

&&

.PREV DISCUSSION... /ISSUED 854 PM CDT FRI APR 24 2009/

UPDATE...
THE SINGULAR SHOWER AND THUNDERSTORM OVER PORTIONS OF CENTRAL AND
SOUTHWEST OKLAHOMA HAVE DISSIPATED THIS EVENING AS THE BOUNDARY
LAYER COOLED AND INSTABILITIES DECREASED. WITH THE PASSAGE OF AN
UPPER WAVE TO THE EAST OF THE AREA THIS EVENING AND THE COOLING
SURFACE TEMPERATURES... DO NOT SEE MUCH TO SUPPORT ANY ADDITIONAL
DEVELOPMENT OVERNIGHT. T-STORMS DEVELOPING ALONG THE COLD FRONT IN
NORTHERN KANSAS SHOULD STAY WELL TO THE NORTH OF THE CWA THROUGH
THE NIGHT. OTHER THAN CLEANING UP THE POPS AND WX GRIDS... LITTLE
CHANGE MADE TO THE REMAINDER OF THE FORECAST FOR THE OVERNIGHT
HOURS.

PREV DISCUSSION... /ISSUED 654 PM CDT FRI APR 24 2009/

AVIATION...
AN ISOLATED STORM COMPLEX TO THE SSW OF THE OKC METRO AREA IS
EXPECTED TO DISSIPATE THIS EVENING BEFORE NEARING ANY TERMINAL
LOCATIONS. MEANWHILE... GUSTY SOUTH WINDS WILL CONTINUE TO DRAW
INCREASING MOISTURE NORTH INTO THE AREA... RESULTING IN MVFR...
WITH OCCASIONAL IFR... CEILINGS ACROSS ALL BUT THE NW OK TERMINALS
LATER TONIGHT. CEILINGS WILL GRADUALLY RISE THROUGH THE DAY
SATURDAY.

PREV DISCUSSION... /ISSUED 643 PM CDT FRI APR 24 2009/

UPDATE...
UPDATED GRIDS TO ACCOUNT FOR ISOLATED COMPLEX OF MARGINALLY SEVERE
STORMS TO THE SSW OF THE METROPLEX. EXPECT THAT ACTIVITY WILL
DISSIPATE LATER THIS EVENING AS BOUNDARY LAYER STABILIZES AND LOW
LEVEL FORCING WEAKENS.

PREV DISCUSSION... /ISSUED 246 PM CDT FRI APR 24 2009/

DISCUSSION...
SOUTHWEST FLOW BECOMING ESTABLISHED TODAY AND LOOKS TO CONTINUE FOR
THE FORESEEABLE FUTURE. THIS WILL MEAN THE START OF AN PROLONGED
ACTIVE PERIOD ACROSS OKLAHOMA AND WESTERN NORTH TEXAS. ALTHOUGH A
FEW SHWRS/TSTMS MAY OCCUR THIS EVENING ASSOCIATED WITH MID-LEVEL
WAVE MOVING CROSS TX... REAL BEGINNING OCCURS SAT AFTN.

BY LATE IN THE DAY TOMORROW SFC COLD FRONT AND DRYLINE APPROACH
WESTERN AND NORTHERN BORDERS OF OK. ALTHOUGH CAPPING INVERSION IS
EXPECTED TO LIMIT CONVECTION... ANY STORMS THAT DO DEVELOP IN THE
ANTICIPATED ENVIRONMENT ACROSS WESTERN OK WILL LIKELY BE SEVERE.
SIMILAR SITUATION TO OCCUR AGAIN SUN AFTN WITH PERHAPS EVEN MORE
MID-LEVEL SUPPORT AS STRONGER WAVE EJECTS OUT OF WESTERN TROUGH.
COULD SEE FIRST ROUND OF MORE WIDESPREAD SIGNIFICANT PRECIP SUN
NIGHT INTO MON BEFORE SFC FRONT MAKES A RUN SOUTH TOWARD THE RED
RIVER MON NIGHT INTO TUE.

AS NEXT WAVE DROPS INTO WESTERN TROUGH... SFC FRONT LIFTS BACK NORTH
TUE NIGHT INTO WED SETTING THE STAGE FOR A REPEAT PERFORMANCE OF THE
EARLIER SCENARIO FOR THE SECOND HALF OF THE UPCOMING WEEK. AGAIN
MULTIPLE SEVERE WX EPISODES AND HEAVY RAIN ARE POSSIBLE. LATEST GFS
THEN... SHOWS THE NEXT SFC FRONT MOVING TOWARD THE RED RIVER BY
FOLLOWING WEEKEND BEFORE POSSIBLY LIFTING BACK NORTH AND DOING THE
WHOLE THING AGAIN DURING THE FIRST WEEK OF MAY.

THE DAY TO DAY DETAILS WILL BE HARD TO FORESEE FARTHER OUT AS WHAT
OCCURS ON A PARTICULAR DAY WILL INFLUENCE THE NEXT TO SOME DEGREE.
HOWEVER THE BIG PICTURE CONT TO SHOW SOUTHWEST MID-LEVEL FLOW
THROUGH 240HRS. THIS WILL LIKELY KEEP WX ACTIVE ACROSS SOUTHERN
PLAINS.

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

.DAY ONE...TONIGHT...

THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE NOT EXPECTED.

DISCUSSION...
AN UPPER LEVEL DISTURBANCE OVER EASTERN OKLAHOMA AND EASTERN TEXAS
WILL MOVE EAST OVERNIGHT. SUBSIDENCE IN THE WAKE OF THIS DISTURBANCE
WILL RESULT IN MINIMAL CHANCES OF THUNDERSTORMS OVERNIGHT.

PROBABILITY TABLE...
VALID THROUGH 500 AM CDT SATURDAY APR 25.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...10 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...10 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

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

THUNDERSTORM OUTLOOK...
A PROLONGED PERIOD OF ACTIVE WEATHER FOR THE SOUTHERN PLAINS...
INCLUDING THE POTENTIAL FOR SEVERE THUNDERSTORMS AND FLOODING
RAIN... WILL LIKELY BEGIN THIS WEEKEND AND CONTINUE WELL INTO NEXT
WEEK. GULF MOISTURE RETURN INTO THE SOUTHERN PLAINS WILL CONTINUE
THROUGH EARLY NEXT WEEK. A DRY LINE WILL REMAIN IN THE AREA OF WEST
TEXAS THROUGH THE WEEKEND. A SLOW MOVING COLD FRONT WILL DRIFT
SOUTHEAST INTO THE NORTHWESTERN CORNER OF OKLAHOMA AS EARLY AS
SATURDAY AFTERNOON. THIS FRONT IS FORECAST TO REMAIN IN OR NEAR THE
OKLAHOMA AND NORTH TEXAS AREA FROM SUNDAY THROUGH THE MIDDLE OF NEXT
WEEK. ALL OF THIS WILL TAKE PLACE BENEATH A STRONG AND PERSISTENT
SOUTHWESTERLY FLOW ALOFT... WHICH WILL FEATURE SEVERAL EMBEDDED
DISTURBANCES. MOISTURE... INSTABILITY... AND VERTICAL WIND PROFILES
WILL BE FAVORABLE FOR MULTIPLE ROUNDS OF STRONG TO SEVERE
THUNDERSTORMS FROM LATE SATURDAY THROUGH WEDNESDAY.

FOR THIS WEEKEND... THERE IS A SLIGHT RISK OF SEVERE STORMS LATE
SATURDAY AND SATURDAY NIGHT ACROSS PARTS OF WESTERN... CENTRAL...
AND NORTHERN OKLAHOMA... AND PARTS OF WESTERN NORTH TEXAS. A STRONG
CAP MAY LIMIT THUNDERSTORM DEVELOPMENT. HOWEVER... IF SEVERE STORMS
DO DEVELOP... VERY LARGE HAIL AND STRAIGHT-LINE WINDS WILL BE THE
MAIN CONCERNS. ON SUNDAY... THERE IS A RISK OF SEVERE STORMS ACROSS
MUCH OF OKLAHOMA AND ALL OF WESTERN NORTH TEXAS. THERE IS SOME
UNCERTAINTY AS TO WHERE THE SURFACE FEATURES WILL SET UP SUNDAY BUT
THE CAP IS EXPECTED TO BE WEAKER ON SUNDAY. SEVERE STORMS COULD
DEVELOP ALONG AND EAST OF A DRYLINE LOCATED IN THE TEXAS PANHANDLE
LATE SUNDAY AFTERNOON. STRONG SHEAR AND INSTABILITY WILL DEVELOP
WITH LARGE HAIL... DAMAGING WINDS... AND TORNADOES POSSIBLE WITH ANY
SEVERE STORMS. THE STORMS MAY THEN DEVELOP INTO ONE OR MORE
THUNDERSTORM COMPLEXES AND MOVE ACROSS THE AREA SUNDAY NIGHT WITH
DAMAGING WINDS AND LARGE HAIL BECOMING THE PRIMARY CONCERN. THE RISK
OF SEVERE STORMS WILL CONTINUE NEXT WEEK... NEARLY EVERY DAY AND
NIGHT... THROUGH WEDNESDAY... WITH POSSIBILITIES BEING SOMEWHAT
DEPENDENT ON WHAT OCCURS THE PREVIOUS DAY AND NIGHT.

OTHER HAZARDOUS WEATHER...
HEAVY RAIN COULD LEAD TO FLOODING BY NEXT WEEK... INCLUDING AN
INCREASING POTENTIAL FOR MAINSTEM RIVER FLOODING BY MIDWEEK.
WIDESPREAD RAINFALL TOTALS OF 2 TO 4 INCHES ARE LIKELY BETWEEN THIS
WEEKEND AND NEXT WEDNESDAY. LOCAL TOTALS GREATER THAN 5 INCHES WILL
BE POSSIBLE.

STRONG SOUTH WINDS WILL OCCUR OVER MUCH OF OKLAHOMA AND NORTHERN
TEXAS ON SATURDAY THROUGH AT LEAST SUNDAY. SUSTAINED WINDS NEAR 30
MPH WITH GUSTS IN EXCESS OF 40 MPH WILL BE POSSIBLE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 5 AM
SATURDAY.
