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.

TO BASEBALL SIZE HAIL AND DESTRUCTIVE WINDS IN EXCESS OF 75 MPH
LIKELY. LOW LEVEL WIND SHEAR IS ALSO FORECASTED TO INCREASE

.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
