Severe Thunderstorm Warning 54, NWS Tulsa, OK

AREA FORECAST DISCUSSION FOR EASTERN OKLAHOMA
NATIONAL WEATHER SERVICE TULSA OK
900 PM CDT SAT APR 9 1994

ALL IS QUIET FOR THE MOMENT ACROSS ERN OK AS CAP BARELY HELD ON SOUTH
OF THE FRONT THIS AFTERNOON. SEVERE TSTMS CONTINUE JUST NORTH OF THE
SFC FRONT IN SOUTH CENTRAL AND SE KS ATTM AND APPEAR DESTINED TO REMAIN
NORTH OF OK.

LATEST SFC MESONET DATA INDICATE SFC LOW TO BE NEAR WAYNOKA. ONGOING KS
CONVECTION HAS HELPED SET UP A GOOD PRESSURE RISE/FALL COUPLET WITH
THIS LOW AND AS A RESULT THE COLD FRONT WAS BEING PULLED SOUTH AT A
PRETTY GOOD CLIP INTO NW OK. THE KS CONVECTION HAS REINFORCED THE
THERMAL GRADIENT ALONG THE FRONT AND EXPECT THE LARGE MASS OF RAIN
COOLED AIR TO THE NORTH OF THE FRONT TO WIN OUT AND BEGIN TO CAUSE THE
SFC FRONT TO SAG SOUTH INTO NE OK OVERNIGHT...CONTRARY TO ALL MODEL
FCSTS. WOULD EXPECT TSTMS TO DEVELOP SOUTH INTO NE OK OVERNIGHT AS WELL
WITH A HIGH POTENTIAL FOR SEVERE WEATHER WITH ANY STORMS WHICH GET
GOING.

EXPECT FRONT TO CONTINUE TO SAG SOUTH SUNDAY AS RAIN COOLED OUTFLOW
CONTINUES TO BE THE DOMINATING FACTOR IN SPITE OF BACKING UPPER FLOW.
APPEARS TO BE A REASONABLE CHANCE FOR SOME SUNSHINE IN SE OK SUNDAY
BEFORE THE FRONT ARRIVES AND THIS COULD CAUSE TEMPS TO SOAR AND ENHANCE
THE SEVERE WEATHER POTENTIAL BY SUNDAY AFTERNOON.

HARD TO TELL AT THIS TIME JUST WHEN THE FRONT WILL CLEAR FAR SE OK BUT
WOULD EXPECT ALL OF ERN OK TO BE IN THE COLDER AIR BY EARLY MONDAY.
WILL ADJUST TEMPS THROUGHOUT ALL FOUR PERIODS OF THE FCST TO REFLECT
EXPECTED FRONTAL POSITIONS AND OBSERVED TEMPS NORTH OF THE FRONT TODAY.
WILL RAISE MINS IN SE OK TONIGHT WITH MLC NOT LIKELY TO GET MUCH IF ANY
BELOW 70 UNLESS ORGANIZED CONVECTION CAN DEVELOP IDN THAT AREA BEFORE
MORNING.

.TUL...NONE.
