A WIND ADVISORY REMAINS IN EFFECT UNTIL 7 PM CDT THIS EVENING. 

IN MUCH OF OKLAHOMA AND WESTERN NORTH TEXAS...SUSTAINED WINDS WILL
AVERAGE 25 TO 30 MPH...WITH GUSTS OVER 40 MPH THROUGH MID EVENING.
WIND SPEEDS WILL DECREASE SLIGHTLY WITH NIGHTFALL AND DEVELOPMENT
OF A THIN STABLE LAYER OF AIR NEAR THE GROUND. THIS STABLE LAYER
MAY NOT PREVENT STRONGER GUSTS IN NORTHWEST OKLAHOMA...BENEATH A
STRENGTHENING LOW LEVEL JET. NORTHWEST OKLAHOMA WILL BE MONITORED
FOR A POSSIBLE EXTENSION OF THE WIND ADVISORY.

A WIND ADVISORY MEANS THAT SUSTAINED WINDS OVER 30 MPH ARE
EXPECTED. WINDS THIS STRONG CAN MAKE DRIVING DIFFICULT...
ESPECIALLY FOR HIGH PROFILE VEHICLES. USE EXTRA CAUTION.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
323 AM CDT WED APR 30 2008

.DISCUSSION...
WIND... FIRE WX... AND SVR STORMS ARE THE CONCERN OVER THE NEXT
COUPLE OF DAYS.

STRONG WINDS EXPECTED TODAY AS SFC LOW DEVELOPS IN EASTERN CO AND
GRADIENT INCREASES. WILL ISSUE A WIND ADVISORY FOR THE ENTIRE FA FOR
15-00Z. WIND ADVISORY MAY NEED TO BE EXTENDED INTO THE OVERNIGHT
HOURS FOR PARTS OF THE AREA AS WINDS ARE EXPECTED TO REMAIN STRONG
TONIGHT... WITH MODELS SHOWING 85H WINDS RANGING FROM 55-70KTS
/DEPENDING ON WHICH MODEL/. SO AT THE VERY LEAST WINDS WILL REMAIN
BREEZY TONIGHT. WILL LET DAY SHIFT ASSESS FOR POSSIBLE WIND ADVISORY
TONIGHT. MEANWHILE... A DRYLINE WILL SETUP IN OR NEAR FAR
WESTERN PORTIONS OF FA TODAY. THE STRONG WINDS... WARM
TEMPERATURES... AND LOW HUMIDITIES WEST OF THE DRYLINE WILL COMBINE
TO ELEVATE THE WILDFIRE POTENTIAL THIS AFTN. FIRE WX WILL BE A
CONCERN AGAIN THURSDAY AS THE DRYLINE MOVES FURTHER EAST. VERY WARM
TEMPERATURES AND LOW HUMIDITIES WILL COMBINE WITH STRONG WINDS TO
ONCE AGAIN ELEVATE THE WILDFIRE POTENTIAL ACROSS PARTS OF WESTERN OK
AND WEST N TX. WILL CONT WITH CURRENT CONFIGURATION OF RED FLAG
WARNING FOR TODAY AND FIRE WX WATCH FOR THURSDAY THAT WAS ISSUED
EARLIER ON THE EVENING SHIFT. WINDY CONDITIONS WILL CONT THURSDAY
WITH BLOWING DUST POSSIBLE IN PARTS OF THE FA THU AFTN/EVENING.

NOW TO TAKE A LOOK AT THE TSTM/SVR WX POTENTIAL THURSDAY/THURSDAY
NIGHT. MID/UPR LVL LOW WILL DEVELOP AND MOVE INTO THE CENTRAL PLAINS
THU/THU NIGHT. MEANWHILE... THE DRYLINE WILL MOVE EAST TO NEAR THE
I-35 CORRIDOR THU. COLD FRONT WILL MOVE INTO NW OK LATE THU AND MOVE
ACROSS THE FA THU NIGHT OVERTAKING THE DRYLINE. MOISTURE HAS BEGUN
TO SPREAD NORTHWARD ACROSS THE REGION OVERNIGHT/EARLY THIS MORNING
AND WILL CONT SPREAD NORTH ON THE STRONG SOUTHERLY WINDS TODAY INTO
THU. THERE IS STILL SOME QUESTION AS TO THE QUALITY/DEPTH OF THE
RETURNING MOISTURE WHICH WILL AFFECT THE POSSIBILITY OF SVR
THUNDERSTORMS. A CAP MAY ALSO AFFECT THE ABILITY FOR CONVECTION TO
DEVELOP LATE THU AFTN. HOWEVER... ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS WILL BE POSSIBLE NEAR THE DRYLINE LATE THU AFTN.
THUNDERSTORMS MAY ALSO DEVELOP ALONG THE FRONT AND BUILD
SOUTHWESTWARD INTO THE FA THU EVENING/OVERNIGHT. IF SUFFICIENT
MOISTURE IS ABLE TO MOVE INTO THE FA... AN UNSTABLE AIRMASS WILL
DEVELOP EAST OF THE DRYLINE AND SOUTH OF THE FRONT. THIS UNSTABLE
AIRMASS AND FAVORABLE WIND SHEAR WILL COMBINE TO MAKE SEVERE
THUNDERSTORMS POSSIBLE LATE THU AFTN/THU NIGHT.

SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE AGAIN LATE THIS WEEKEND
INTO EARLY NEXT WEEK AS ANOTHER STORM SYSTEM APPROACHES AND MOVES
ACROSS THE REGION.

AS FOR ADJUSTMENTS TO INITIALIZATIONS... RAISED HIGHS ACROSS PARTS
OF THE AREA FOR TODAY SINCE GUIDANCE NUMBERS IN SOME LOCATIONS WERE
LOWER THAN HIGHS SEEN YESTERDAY. SOME HIGH CLOUDS MAY CURTAIL THE
WARM UP. HOWEVER... WITH MIXING AND A WARMER START THIS MORNING
BELIEVE HIGHS WILL REACH AT LEAST THE SAME LVLS AS YESTERDAY. ALSO
RAISED TEMPS IN SW PORTION OF FA THU FOR HEAT UP BEHIND DRYLINE.
ADJUSTED WINDS FOR TODAY/TONIGHT TO SHOW CURRENT THINKING. ALSO
ADJUSTED DEWPTS FOR TODAY THROUGH THU TO BETTER DEFINE/SHOW TIGHTER
GRADIENT/ OF DRYLINE. ALSO WENT WITH PERSISTENCE WITH POPS FOR THU
AFTN.

1025 PM CDT TUE APR 29 2008

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...
DRY AND STABLE CONDITIONS WILL PRECLUDE THUNDERSTORM DEVELOPMENT.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT WEDNESDAY APR 30.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...ZERO.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

THUNDERSTORM OUTLOOK...
THERE IS A RISK OF SEVERE THUNDERSTORMS LATE THURSDAY AND THURSDAY
NIGHT OVER CENTRAL AND EASTERN OKLAHOMA. LOW-LEVEL GULF MOISTURE
WILL RETURN NORTHWARD WEDNESDAY AND THURSDAY... SETTING UP A
DRY LINE BY LATE WEDNESDAY NEAR THE WESTERN BORDER OF OKLAHOMA.
MOISTURE RETURN AND DESTABILIZATION WILL BE INSUFFICIENT TO OVERCOME
A CAPPING LAYER OF WARM AIR ALOFT UNTIL THURSDAY.  THEREFORE
THUNDERSTORMS ARE NOT EXPECTED THROUGH WEDNESDAY NIGHT. BY
THURSDAY... A POWERFUL STORM SYSTEM WILL MOVE INTO THE CENTRAL
UNITED STATES. THE DRY LINE IS EXPECTED TO MOVE EAST INTO CENTRAL
OKLAHOMA BY LATE THURSDAY. THE CONTINUED INCREASE IN GULF MOISTURE
AHEAD OF THE DRY LINE WILL RESULT IN UNSTABLE CONDITIONS BY THAT
TIME... WHILE STRENGTHENING WINDS ALOFT WILL SET UP STRONG VERTICAL
WIND SHEAR. IF STORMS DEVELOP... THE ENVIRONMENTAL CONDITIONS LATE
THURSDAY WILL BE CAPABLE OF SUPPORTING SEVERE THUNDERSTORMS EAST OF
THE DRY LINE.

THE MOST LIKELY SCENARIO AT THIS TIME IS THAT THE CAP WILL PREVENT
STORM FORMATION UNTIL LATE THURSDAY AFTERNOON... AT WHICH TIME
ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE NEAR AND EAST
OF THE DRY LINE. A COLD FRONT WILL OVERTAKE THE DRY LINE FROM THE
NORTHWEST THURSDAY EVENING WITH ADDITIONAL THUNDERSTORM DEVELOPMENT
POSSIBLE ALONG THE FRONT AS IT MOVES THROUGH CENTRAL AND SOUTHEAST
OKLAHOMA THURSDAY NIGHT.

THERE WILL ALSO BE A CHANCE OF THUNDERSTORMS ACROSS OKLAHOMA AND
WESTERN NORTH TEXAS SUNDAY AND MONDAY.

OTHER HAZARDOUS WEATHER...
WILDFIRE POTENTIAL WILL REMAIN HIGH WEDNESDAY AFTERNOON OVER FAR
WESTERN PARTS OF NORTH TEXAS AND OKLAHOMA. A RED FLAG WARNING IS IN
EFFECT FOR THESE AREAS. WILDFIRE POTENTIAL WILL BE VERY HIGH TO
EXTREME AGAIN ON THURSDAY OVER A LARGER PART OF WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS...WHERE A FIRE WEATHER WATCH IS IN EFFECT.

STRONG SOUTH WINDS ON WEDNESDAY MAY REACH SUSTAINED SPEEDS OVER 30
MPH... WITH GUSTS OVER 40 MPH... OVER MOST OF OKLAHOMA AND NORTHERN
TEXAS. STRONG WINDS WILL CONTINUE THROUGH THURSDAY EVENING...
BECOMING SOUTHWEST AND WESTERLY BEHIND THE DRY LINE AND POSSIBLY
SPREADING BLOWING DUST INTO PARTS OF SOUTHWESTERN OKLAHOMA AND
WESTERN NORTH TEXAS. STRONG NORTH WINDS WILL FOLLOW THE COLD FRONT
THURSDAY EVENING AND THURSDAY NIGHT. SECURING OF OUTDOOR
FURNITURE... TRASH CANS... AND OTHER POTENTIAL WIND-BLOWN OBJECTS IS
RECOMMENDED BEFORE WEDNESDAY. CAUTION ALSO WILL BE NEEDED WHILE
DRIVING DUE TO THE POSSIBILITY OF STRONG CROSSWINDS.

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