AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
538 AM CDT WED JUN 20 2007

.UPDATE...
LOOKS LIKE RAIN IS GOING TO LAST A BIT LONGER ACROSS NORTHEAST
OKLAHOMA UNDER THE INFLUENCE OF AN MCV JUST SOUTH OF TULSA. HAVE
UPDATED FIRST PERIOD POPS TO REFLECT THIS.

.PREV DISCUSSION... /ISSUED 501 AM CDT WED JUN 20 2007/

UPDATE...
SENT UPDATE TO INCLUDE SEVERE THUNDERSTORM WATCH 427 FOR CHOCTAW
COUNTY.

PREV DISCUSSION... /ISSUED 331 AM CDT WED JUN 20 2007/

DISCUSSION...
ONGOING THUNDERSTORM COMPLEX WILL MAKE FOR A TRICKY FORECAST TODAY
AND TONIGHT. THE NORTHERN EDGE OF THE COMPLEX HAS SLOWED DOWN
SOME...WHILE THE STORMS NEAR THE RED RIVER IN SOUTH CENTRAL
OKLAHOMA ARE MOVING A BIT FASTER. LOCAL CONVECTIVE ANALYSIS
INDICATES HIGHER INSTABILITY /CAPE VALUES OF 2000 TO 2500 J/KG AT
2AM/ ACROSS SOUTHEAST OKLAHOMA AND NORTHWEST ARKANSAS...WHERE THE
ATMOSPHERE WAS NOT WORKED OVER BY EARLIER CONVECTION. EXPECT THE
CURRENT LINE OF STORMS TO MOVE A LITTLE FURTHER SOUTHEAST BEFORE
FALLING APART. MODELS ALL OVER THE PLACE ON WHAT HAPPENS WITH
REMNANTS OF THE MCS...BUT WITH AN MCV AND REMAINING OUTFLOW
BOUNDARIES AROUND...ADDITIONAL DEVELOPMENT COULD OCCUR TODAY AND
TONIGHT...WITH ANOTHER ROUND OF STRONG TO SEVERE THUNDERSTORMS
POSSIBLE. IF SEVERE STORMS DO FORM...LARGE HAIL AND HIGH WINDS
WILL BE THE PRIMARY THREATS...THOUGH AN ISOLATED TORNADO MAY BE
POSSIBLE NEAR BOUNDARIES WHERE THE SRH CAN BE MAXIMIZED.

GFS HINTS AT THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON
THURSDAY...WITH THE WRF KEEPING THINGS DRY. HAVE OPTED TO KEEP A
MENTION OF STORMS OUT OF THE FORECAST FOR NOW. CONVECTION THURSDAY
WILL LIKELY BE TIED TO WHAT HAPPENS TODAY...AND WITHOUT SYNOPTIC
FORCING...ANY STORMS THURSDAY WOULD OCCUR FROM LINGERING MCV/OUTFLOW
BOUNDARIES.

MODELS ARE BRINGING A COLD FRONT THROUGH THE CENTRAL PLAINS ON
FRIDAY...BUT THE FRONT LOSES DEFINITION BY THE TIME IT REACHES THE
OKLAHOMA/KANSAS STATE LINE FRIDAY NIGHT. THIS FEATURE WILL BEAR
WATCHING IN LATER MODEL RUNS. A RIDGE OF MID/UPPER LEVEL HIGH
PRESSURE THEN BUILDS OVER THE REGION THROUGH THE WEEKEND...AND MID
LEVEL TEMPS CONTINUE TO WARM AS WELL. THIS SHOULD BE ENOUGH TO
SUPPRESS STORM DEVELOPMENT AND HAVE KEPT THE FORECAST DRY THROUGH
THE EXTENDED. HOT AND HUMID CONDITIONS WILL CONTINUE THROUGH MID
WEEK...SO HAVE STAYED NEAR GUIDANCE TEMPS.
