Area forecast discussion, Jun 9, 3:39 PM CDT, 1 hour 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
339 PM CDT THU JUN 9 2005

.DISCUSSION...
SCATTERED THUNDERSTORMS ALREADY BEGINNING TO DEVELOP ALONG THE
OUTFLOW BOUNDARY WITH STRONG STORM IN DEWEY COUNTY AND ALSO IN
SOUTHWEST KANSAS NEAR KDDC. SATELLITE ALSO SHOWS THE DRYLINE IS
TRYING TO GO IN SOUTHWEST KANSAS AND THE EASTERN OKLAHOMA
PANHANDLE. INSTABILITY AND SHEAR WILL SUPPORT CONTINUED
THUNDERSTORM DEVELOPMENT AND INCREASING LOW LEVEL JET THIS EVENING
WILL LIKELY INCREASE COVERAGE. HAVE HIT POPS HIGHEST IN THE WEST
IN THE VICINITY OF THE BOUNDARIES.

AFTER THIS... THE WEATHER WILL BE HIGHLY DEPENDENT ON MESOSCALE
EVOLUTION OVER THE NEXT FEW DAYS WITH ANY CONVECTIVE BOUNDARIES
THAT MAY BE IN THE AREA ETC. HARD TO PIN THOSE DOWN VERY FAR AHEAD
SO WILL BROADBRUSH POPS AND WEATHER BASED ON THE SYNOPTIC PATTERN
AND SEE HOW THINGS EVOLVE WITH TIME. CONVECTION IS STILL A GOOD
BET WITH THE LONGWAVE TROUGH TO THE WEST AND VARIOUS SHORTWAVES
APPROACHING THE AREA OVER THE NEXT COUPLE OF DAYS.

THERE IS STILL SOME UNCERTAINTY ON WHEN TO END PRECIP CHANCES AS
MEDIUM RANGE MODELS SHOW VARIOUS SOLUTIONS WITH THE MOVEMENT OF
THE WESTERN TROUGH. GFS TAKES WAVE QUICKLY INTO THE UPPER MIDWEST
BY MONDAY EVENING WHILE THE 00Z ECMWF STILL HAD A CLOSED UPPER LOW
OVER SOUTHEAST COLORADO AT THE SAME TIME. HAVE KEPT POPS INTO
TUESDAY IN THE EAST COVERING THE POTENTIAL SLOWER SOLUTION... BUT
HIGHEST CHANCES WILL BE THROUGH SUNDAY NIGHT.

ERICK... TO WEATHERFORD... TO ALVA. THE SLIGHT RISK AREA INCLUDES
ALL LOCALES TO THE SOUTHWEST OF A LINE FROM CHEROKEE... TO CUSHING.

TIMING...
SEVERE STORMS ARE ONGOING ACROSS PARTS OF NORTHWEST OKLAHOMA... AND
AREAL COVERAGE OF SEVERE STORMS WILL ONLY INCREASE THROUGH THE
EVENING HOURS.  THE SEVERE THREAT WILL CONTINUE WELL INTO THE
OVERNIGHT HOURS.

EXPECTED WEATHER AN IMPACTS...
ANY SUPERCELL STORMS THAT AFFECT WESTERN OKLAHOMA THIS EVENING WILL
BE CAPABLE OF HAIL UP TO THE SIZE OF BASEBALLS... AND DESTRUCTIVE
WINDS IN EXCESS OF 75 MPH. THERE WILL ALSO BE A THREAT OF TORNADOES
WITH ANY ORGANIZED SUPERCELLS BETWEEN 4 AND 10 PM THIS EVENING.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL IN ALL AREAS
EXCEPT NORTH CENTRAL OKLAHOMA SHOULD PLAN FOR SEVERE WEATHER
OPERATIONS THROUGH TONIGHT.

DISCUSSION...
AN OUTFLOW BOUNDARY EXTENDING ROUGHLY FROM NORMAN... TO
WEATHERFORD... TO GAGE WILL SLOWLY MOVE NORTHWARD THROUGH THIS
EVENING. A DRYLINE HAS ALSO BECOME WELL-DEFINED FROM THE EASTERN
TEXAS PANHANDLE... NORTHWARD TO NEAR BEAVER OKLAHOMA... AND INTO
SOUTHWEST KANSAS... AND INTERSECTED THE OUTFLOW BOUNDARY NEAR MEADE
KANSAS. TO THE EAST OF THE DRYLINE AND ALONG AND SOUTH OF THE
OUTFLOW BOUNDARY... THE AIRMASS HAS BECOME EXTREMELY UNSTABLE...
WITH CAPE VALUES IN EXCESS OF 5000.  DEEP LAYER WIND SHEAR IS
INCREASING AND IS MORE THAN SUFFICIENT TO SUPPORT SUPERCELL STORMS.
SEVERE STORMS ARE EXPECTED TO INCREASE IN COVERAGE ACROSS NORTHWEST
OKLAHOMA THROUGH THE EARLY EVENING... WITH SUPERCELLS PRODUCING UP
TO BASEBALL SIZE HAIL AND DESTRUCTIVE WINDS IN EXCESS OF 75 MPH
LIKELY. LOW LEVEL WIND SHEAR IS ALSO FORECASTED TO INCREASE
SUBSTANTIALLY ACROSS WESTERN OKLAHOMA BETWEEN 6 AND 10 PM THIS
EVENING... WHICH WILL RESULT IN AN INCREASING TORNADO THREAT WITH
ANY SUPERCELLS IN THE MID TO LATE EVENING HOURS. STORMS MAY CONGEAL
INTO A LARGE COMPLEX THAT THEN MOVES EASTWARD WELL INTO THE
OVERNIGHT HOURS... WITH A CONTINUED THREAT OF HAIL UP TO GOLF BALL
SIZE... ALONG WITH WINDS UP TO 70 MPH AND HEAVY RAINFALL.

              NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...100 PERCENT.

OTHER HAZARDOUS WEATHER...
LOCALLY HEAVY RAINFALL IN EXCESS OF 2 TO 3 INCHES MAY CAUSE LOCAL
FLASH FLOODING.

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

THUNDERSTORM OUTLOOK...
THE POTENTIAL FOR SEVERE WEATHER WILL CONTINUE EACH DAY THROUGH THE
WEEKEND AND INTO EARLY NEXT WEEK. A LARGE-SCALE TROUGH OVER THE
WESTERN UNITED STATES WILL RESULT IN RICH LOW LEVEL MOISTURE AND
STRONG INSTABILITY REMAINING IN PLACE ACROSS THE SOUTHERN PLAINS...
AND DEEP LAYER SHEAR PROFILES WILL CONTINUE TO IMPROVE AS WINDS IN
THE MID AND UPPER LEVELS INCREASE. THE HIGHEST CHANCES FOR
SUPERCELLS AND ASSOCIATED HIGHER-END SEVERE WEATHER WILL BE MAINLY
ACROSS THE WESTERN THIRD OF OKLAHOMA LATE EACH AFTERNOON AND
EVENING... WITH COMPLEXES OF STORMS MOVING EASTWARD INTO THE MAIN
BODY OF OKLAHOMA AND WESTERN NORTH TEXAS DURING THE OVERNIGHT AND
MORNING HOURS. PEOPLE WITH TRAVEL OR OUTDOOR PLANS THROUGH EARLY
NEXT WEEK ARE STRONGLY ENCOURAGE TO STAY AWARE OF THE LATEST WEATHER
INFORMATION.

OTHER HAZARDOUS WEATHER...
LOCALLY HEAVY RAINFALL MAY ACCOMPANY ANY NIGHT TIME COMPLEXES OF
STORMS JUST ABOUT ANYWHERE ACROSS THE SOUTHERN PLAINS.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 7 AM
FRIDAY MORNING JUNE 10.
