AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
804 PM CDT TUE APR 29 2008

.DISCUSSION...
UPDATED GRIDS TO UPGRADE FIRE WEATHER WATCH TO A RED FLAG WARNING
TOMORROW. ALSO ISSUED A FIRE WEATHER WATCH FOR THURSDAY AS DRY
LINE PROGRESSES EASTWARD OVER SOUTHWEST OKLAHOMA AND PORTIONS OF
WESTERN NORTH TEXAS. ALONG WITH THESE MODIFICATIONS...WE DID MAKE
ADJUSTMENTS TO DEWPOINT GRIDS...TO BETTER ALIGN WITH MODEL GRID
SOLUTIONS...AS ADJUSTED MOS VALUES APPEAR UNREALISTICALLY HIGH (70
DEWPOINTS ACROSS SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA BY 18Z
THURSDAY). GIVEN STATE OF GULF AND EXPECTED TRAJECTORIES...WE WILL
BE LUCKY TO MAKE MID-60 DEWPOINTS LATE THURSDAY ACROSS FAR
SOUTHEAST OKLAHOMA. WITH MUCH MORE CONFIDENCE IN LOWER MOISTURE
VALUES...WE WILL DEVIATE FROM OUR EXPERIMENTAL INITIALIZATIONS.

WITH MODERATE-STRONG WIND FIELDS BEHIND DRY LINE THURSDAY...WE
INTRODUCED THE MENTIONING OF BLOWING DUST TO MOST OF SOUTHWEST
INTO CENTRAL OKLAHOMA...AND ALL OF WESTERN NORTH TEXAS FOR
THURSDAY AFTERNOON AND EVENING BEHIND DRY LINE.

&&

.PREV DISCUSSION... /ISSUED 335 PM CDT TUE APR 29 2008/

DISCUSSION...

FIRE WEATHER WILL BE THE MAIN CONCERN TOMORROW... WITH THUNDERSTORM
CHANCES ON THURSDAY AND AGAIN EARLY NEXT WEEK.

THE WINDS WILL BE ON THE INCREASE TOMORROW AS A SURFACE LOW
PRESSURE DEVELOPS OVER EASTERN COLORADO AND WESTERN KANSAS.
MOISTURE SHOULD FINALLY BEGIN TO RETURN NORTH TONIGHT...WHICH
WILL SHARPEN UP A DEVELOPING DRY LINE OVER THE EASTERN TEXAS
PANHANDLE AND WESTERN OKLAHOMA. FIRE WEATHER WILL BE A CONCERN FOR
ANY LOCATIONS ALONG AND WEST OF THE DRY LINE. RIGHT NOW... WE
BELIEVE THAT THE DRY LINE WILL MAKE ONLY MINIMAL EASTWARD
PROGRESS... POSSIBLY ONLY MAKING TO OUR WESTERN ROW OF COUNTIES.
WILL HOLD OFF ON ANY RED FLAG WARNING AND CONTINUE THE FIRE
WEATHER WATCH DUE TO UNCERTAINTY OF THE DRY LINE LOCATION.

ATTENTION THEN TURNS TO THURSDAY AFTERNOON INTO THURSDAY EVENING.
MODELS ARE CONSISTENT IN BRINGING A STORM SYSTEM INTO THE CENTRAL
PLAINS BY THURSDAY AFTERNOON. A DRY LINE WILL BEGIN TO PUSH EAST...
SETTING UP NEAR THE INTERSTATE 35 CORRIDOR BY MID AFTERNOON. AT
THE SAME TIME... A COLD FRONT WILL BE PUSHING INTO NORTHWEST
OKLAHOMA. A COUPLE OF ISSUES CONTINUE TO BE A CONCERN WITH THIS
DEVELOPING STORM SYSTEM. THE FIRST ISSUE IS THE QUALITY OF
MOISTURE THAT WILL BE IN PLACE BY THURSDAY AFTERNOON... WITH THE
SECOND CONCERN BEING THE CAP STRENGTH. CONTINUED SOUTHERLY WINDS
WILL BRING BETTER MOISTURE INTO THE SOUTHERN PLAINS. HOWEVER...
CURRENT WIND OBSERVATIONS OVER THE GULF OF MEXICO SHOW WINDS JUST
BEGINNING TO SWITCH AROUND TO THE EAST SOUTHEAST... WITH DEW POINT
TEMPERATURES IN THE MIDDLE TO UPPER 50S. SOUTH WINDS OVER THE NEXT
24 TO 48 HOURS WILL IMPROVE THE MOISTURE... BUT QUESTION REMAINS
IF ENOUGH MOISTURE WILL BE IN PLACE OVER THE OUN CWA BY THURSDAY
AFTERNOON. IT WILL BE CLOSE BUT CURRENT FORECASTS REFLECTS
SLIGHTLY LOWER THAN IDEAL VALUES FOR WIDESPREAD SEVERE
THUNDERSTORMS. STILL... STRONG DYNAMICS WITH THIS STORM SYSTEM
SHOULD BE ABLE TO ALLOW FOR SOME THUNDERSTORMS TO DEVELOP EAST OF
THE DRY LINE... WITH BETTER CHANCES PUSHING INTO EASTERN OKLAHOMA.

COOL TEMPERATURES RETURN TO THE REGION ON FRIDAY INTO SATURDAY
BEFORE THE NEXT CHANCE OF THUNDERSTORMS ON SUNDAY AND CONTINUING
INTO EARLY NEXT WEEK. THERE IS A CONCERN FOR SEVERE WEATHER ONCE
AGAIN ON MONDAY... BUT WIDESPREAD CLOUD COVER MAY LIMIT THE AMOUNT
OF INSTABILITY REALIZED DURING THE AFTERNOON.

1200 PM CDT TUE APR 29 2008

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

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

THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.

DISCUSSION...
A WARM FRONT... FROM THE NORTHWEST CORNER OF OKLAHOMA SOUTHEASTWARD
INTO SOUTHEAST OKLAHOMA AT MIDDAY... WILL CONTINUE TO MOVE NORTHWARD
THIS AFTERNOON. SOUTH WINDS WILL STRENGTHEN TO THE SOUTH OF THE
FRONT... BUT LOW LEVELS WILL REMAIN DRY AND CONDITIONS WILL REMAIN
TOO STABLE FOR THUNDERSTORM DEVELOPMENT.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT WEDNESDAY APR 30.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...LESS THAN 5 PERCENT.

OTHER HAZARDOUS WEATHER...
DRY AND WINDY CONDITIONS WILL RESULT IN VERY HIGH TO EXTREME
WILDFIRE CONDITIONS THIS AFTERNOON FROM WESTERN PARTS OF NORTH TEXAS
NORTHWARD INTO FAR WESTERN OKLAHOMA. A RED FLAG WARNING IS IN EFFECT
FOR THESE AREAS.

.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 TONIGHT THROUGH 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 VERY 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 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 FIRE WEATHER WATCH 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.

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 SOUTHWESTERLY 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. 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.
