AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
715 PM CDT THU SEP 21 2006

.UPDATE...
DRYLINE HAS PROGRESSED INTO CENTRAL OKLAHOMA BY EARLY THIS
EVENING... AND HAS JUST ABOUT CLEARED ALL OF OUR NORTH CENTRAL
COUNTIES. AS THE UPPER LOW MOVES OUT TO THE NORTH... ADDITIONAL
SUPPORT FOR ACTIVITY ACROSS NORTHWEST OKLAHOMA WILL BE MINIMAL.
WILL REDUCE POPS BEHIND THE DRYLINE... ESPECIALLY ACROSS NORTHWEST
OKLAHOMA. WINDS OVER NORTHWEST OKLAHOMA HAVE ALREADY DROPPED
BELOW HIGH WIND CRITERIA... WILL LIKELY SLIP BELOW WIND ADVISORY
LEVELS BEFORE TOO LONG. SPEEDS HAVE DROPPED OFF CONSIDERABLY OVER
THE CENTRAL AND SOUTH.

&&

.PREV DISCUSSION... (ISSUED 318 PM CDT THU SEP 21 2006)

DISCUSSION...
MULTI-DIMENSIONAL EVENT CURRENTLY UNFOLDING. THE WORST OF THE WINDS
THAT HAVE AFFECTED ABOUT THE WESTERN TWO THIRDS OF OKLAHOMA AND
NORTH TEXAS TODAY IS NEARING AN END AS DRY AIR HAS BEEN
INCORPORATED INTO THE WEST KANSAS UPPER LOW WITH AN ASSOCIATED
OCCLUSION. EXPECT ANOTHER FEW HOURS OF STRONG WINDS TO REMAIN ACROSS
NORTHERN OKLAHOMA HOWEVER WHERE THE PRESSURE GRADIENT IS TIGHTEST
AND SUBSIDENCE HAS OVERSPREAD NORTHWEST OKLAHOMA BEHIND THE FRONT.
MARGINAL HIGH WIND CRITERIA SEEM LIKELY OVER THE HIGHER TERRAIN OF
NORTHWEST OKLAHOMA...AND WILL MONITOR CLOSELY FOR A POSSIBLE UPGRADE
TO A HIGH WIND WARNING.

A NARROW RIBBON OF WEAK TO MODERATELY UNSTABLE AIR HAS FORMED EAST
OF THE FRONT WITH LIFT STRONGEST AHEAD OF THE KANSAS LOW. WILL
MAINTAIN HIGHEST POPS ACROSS NORTH CENTRAL OKLAHOMA THROUGH EARLY
EVENING WHERE ASCENT WILL BE DEEPEST/STRONGEST...WITH SLIGHTLY LOWER
POPS FARTHER SOUTH ALONG THE FRONT AND/OR DRYLINE.

MODELS HAVE THE UPPER LOW CONTINUING ON A NORTHERN TRACK OVERNIGHT
WITH ANOTHER UPPER TROUGH/LOW REFORMING TO ITS WEST. DEEP MOISTURE
THAT HAS LIMITED THE AMOUNT OF SEVERE WEATHER TO THIS POINT SHOULD
SURGE AHEAD OF THE FRONT OVERNIGHT POSSIBLY AFFECTING SOUTHEAST
OKLAHOMA WHERE A HEIGHTENED RISK OF SUPERCELLS MAY OCCUR THIS
EVENING.

REORGANIZATION OF THE UPPER LOW HAS THE FRONT/DRYLINE SEPARATING
INTO DISTINCT FEATURES BY EARLY FRIDAY...WITH THE DRYLINE STALLING
OVER SOUTHEAST OKLAHOMA...AND THE FRONT REDEVELOPING OVER WESTERN
KANSAS WITH THE NEWLY FORMING UPPER LOW. SCATTERED CONVECTION WILL
REMAIN POSSIBLE ALONG THE DRYLINE FRIDAY...BUT THE LARGER ISSUE MAY
BE EXTREME FIRE WEATHER DEVELOPING PER NAM BUFFER SOUNDINGS AND THE
ASSOCIATED WARM/DRY SOUTHWEST FLOW WEST OF THE DRYLINE. HAVE
THEREFORE ISSUED A FIRE WEATHER WATCH FOR ALL AREAS WEST OF THE
EXPECTED POSITION OF THE DRYLINE.

MODEL CONSENSUS THEN HAS THE NEW FRONT MOVING THROUGH THE REGION
FRIDAY NIGHT AND SATURDAY WITH THESE PERIODS LOOKING LIKE THE NEXT
BEST CHANCE OF THUNDERSTORMS...SOME POSSIBLY SEVERE. MUCH WILL
DEPEND ON WHERE THE DRYLINE ENDS UP FRIDAY AND STRENGTH OF THE
ASCENT FIELDS ACCOMPANYING THE NEXT LOW THAT IS STILL EVOLVING.

EXPECT THE FRONT TO CLEAR THE AREA BY LATE SATURDAY WITH
DRIER/STABLE AIR AFFECTING AREA FOR THE FOLLOWING DAYS. MEDIUM RANGE
MODELS SHOW THE POTENTIAL FOR INCREASING MOISTURE RETURN AND RENEWED
THUNDERSTORM CHANCES BY THE MIDDLE OF NEXT WEEK AS ANOTHER FRONT
APPROACHES. MODEL CONSENSUS HAS THE FRONT MOVING THROUGH ON
WEDNESDAY.

450 PM CDT THU SEP 21 2006

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

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

THUNDERSTORM OUTLOOK...
THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT
ACROSS PARTS SOUTH-CENTRAL AND EASTERN OKLAHOMA. A SLIGHT RISK AREA
COVERS CENTRAL PORTIONS OF OKLAHOMA.

LOCATION...
THE MODERATE RISK AREA IS EAST OF A LINE FROM MARIETTA...TO
SULPHUR...TO SEMINOLE. THE SLIGHT RISK AREA COVERS LOCATIONS JUST
WEST OF THE MODERATE RISK...AND LOCATIONS EAST OF A LINE FROM
RINGLING...TO YUKON...TO MEDFORD.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM NOW
THROUGH 10 PM.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
MODERATE AND SLIGHT RISK AREAS SHOULD KEEP UP TO DATE WITH THE
LATEST WEATHER INFORMATION TODAY...AND PLAN FOR SEVERE WEATHER
OPERATIONS THIS AFTERNOON AND EVENING.

DISCUSSION...
A STRONG STORM SYSTEM WILL MOVE NORTHEAST FROM WESTERN KANSAS. A DRY
LINE WILL MOVE THROUGH WESTERN OKLAHOMA AND WESTERN NORTH TEXAS THIS
AFTERNOON AND WILL CONTINUE TO MOVE EAST THIS EVENING. SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF THIS DRY
LINE. INSTABILITY WILL INCREASE AS MOISTURE INCREASES IN THE LOW
LEVELS TODAY. THIS MODERATE INSTABILITY WILL COMBINE WITH VERY
STRONG WIND SHEAR TO BE SUFFICIENT FOR STRONG TO SEVERE
THUNDERSTORMS...INCLUDING LOW-TOPPED SUPERCELLS... WITH THE PRIMARY
THREAT OF DAMAGING WINDS. DESPITE MARGINAL INSTABILITY...THE STRONG
WIND SHEAR IS SUFFICIENT FOR TORNADOES WITH THE MOST ORGANIZED
STORMS.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY SEP 22.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...50 PERCENT.

OTHER HAZARDOUS WEATHER...
A HIGH WIND WARNING IS IN EFFECT UNTIL EARLY THIS EVENING FOR
NORTHWEST OKLAHOMA...AND THIS HIGH WIND WARNING IS SURROUNDED BY A
WIND ADVISORY THAT EXTENDS DOWN INTO WESTERN NORTH TEXAS. SOUTHWEST
AND WEST WINDS GUSTING TO AROUND 60 MPH ARE POSSIBLE IN THE HIGH
WIND WARNING AREA...WITH WINDS OF 25 TO 35 MPH AND GUSTS TO NEAR
50 MPH EXPECTED TO PREVAIL ACROSS THE WIND ADVISORY AREA. THE
COMBINATION OF STRONG WINDS...LOW HUMIDITY AND WARM TEMPERATURES
WEST OF THE DRY LINE WILL ALSO RESULT IN INCREASED FIRE DANGER. AS A
RESULT...A RED FLAG WARNING IS IN EFFECT FOR MUCH OF WESTERN NORTH
TEXAS AND SOUTHWEST OKLAHOMA INTO EARLY THIS EVENING.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

THUNDERSTORM OUTLOOK...
THE POTENTIAL FOR SEVERE WEATHER WILL CONTINUE FOR PARTS OF CENTRAL
AND EASTERN OKLAHOMA ON FRIDAY AND SATURDAY AS ANOTHER UPPER LEVEL
STORM SYSTEM MOVES EASTWARD FROM THE ROCKIES AND A COLD FRONT MOVES
INTO THE AREA.

OTHER HAZARDOUS WEATHER...
NONE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 7 AM
FRIDAY SEPTEMBER 22.
