Area forecast discussion, Jun 4, 3:34 AM CDT, 54 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
334 AM CDT MON JUN 4 2012

.DISCUSSION...

SEVERE CONVECTION AND ONGOING FLASH FLOODING ARE THE MAIN CONCERNS
THIS MORNING. INITIAL CONVECTIVE LINE HAS MADE A SIGNIFICANT
SOUTHWARD PUSH OVER THE PAST FEW HOURS AFTER BEING LARGELY
STATIONARY ACROSS PARTS OF NORTHEAST OKLAHOMA. LIKELY SEVERE
WINDS STILL NOTED IN THE RADAR VELOCITIES...ESPECIALLY THE PART
PUSHING INTO NORTHWEST ARKANSAS. STILL QUITE A BIT OF INSTABILITY
IN SOUTHEAST OKLAHOMA AND NORTHWEST ARKANSAS...WITH ABOUT 2000
J/KG OF CAPE NOTED IN THESE AREAS ON THE LOCAL MESOANALYSIS. SEE
NO REASON THAT THIS LINE WILL NOT CONTINUE TO PRODUCE SEVERE
WEATHER AS IT MOVES THROUGH THE REST OF THE FORECAST AREA. SECOND
BATCH OF STORMS CURRENTLY TO THE NORTHWEST OF TULSA. THIS HAS LESS
SEVERE POTENTIAL DUE TO THE EARLIER STORMS AND RESULTANT REDUCED
INSTABILITY...BUT AS NOTED IN AN EARLIER SEVERE GUST ON THE
MESONET...NOT ENTIRELY IMPOSSIBLE. FORTUNATELY...THESE STORMS ARE
ALSO MOVING MORE QUICKLY...SO THE TRAINING STORMS THAT CAUSED THE
SIGNIFICANT FLOODING NEAR SKIATOOK...VERDIGRIS...AND CLAREMORE
WILL NOT OCCUR WITH THIS ROUND. STILL...AN ADDITIONAL INCH OR SO
OF RAIN MAY AFFECT THE ONGOING FLOODING IN SOUTHERN OSAGE COUNTY.

THE BOUNDARY THAT HAS BEEN LINGERING ACROSS NORTHERN PARTS OF THE
FORECAST AREA WILL BEGIN TO PUSH SOUTHWARD...SHIFTING THE
CONVECTION FOCUS TO THE SOUTHERN PART OF THE FORECAST AREA FOR THE
NEXT FEW DAYS. SMALL THUNDERSTORM CHANCES WILL CONTINUE THROUGH AT
LEAST MID WEEK AS A RESULT. WELL ABOVE NORMAL TEMPERATURES SHOULD
CONTINUE TODAY...WITH A SMALL DECREASE FOR THE NEXT FEW DAYS AFTER
THAT. TEMPERATURES WILL BEGIN TO CLIMB TOWARD NEXT WEEKEND AS
UPPER LEVEL RIDGING BUILDS INTO THE CENTRAL UNITED STATES.
