AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
315 PM CST MON MAR 24 1997

FIRST ISSUE IS TSTM CHANCES TONIGHT.  CAP HAS MAINTAINED SO FAR THIS
AFTERNOON BUT TSTMS SHOULD DEVELOP ALONG FRONT AS IT WORKS INTO
DEEPER MOISTURE. INSTABILITY HAS SPREAD OVER MUCH OF THE WARM SECTOR
AND SOME SVR IS PSBL OVERNIGHT AND WILL MENTION SVR IN EASTERN
2/3RDS OF ZONES.  MAIN THREAT WILL BE HAIL/WINDS. EXPECT TO SEE
MAINLY LINEAR ACTIVITY WITH THE FRONTAL CONVERGENCE. LOW LEVEL
MOISTURE REMAINS RELATIVELY HIGH AFTER FROPA AND UPPER TROF REMAINS
TO THE WEST. THUS POST-FRONTAL SHOWERS ARE ALSO LIKELY TO DEVELOP
TONIGHT.
WILL USE CHC POPS W TO LIKELY CNTRL/EAST TNGT.  WITH PROGD FRONTAL
TIMING... SHRA WILL LIKELY LINGER INTO THE EARLY SECOND PERIOD
ESPECIALLY IN THE SE.

BEYOND TONIGHT... THE MODELS HAVE THREE COMPLETELY DIFFERENT
SOLUTIONS OF THE 24-48 HOUR BEHAVIOR OF UPPER FEATURES.  ETA CUTS OFF
A LOW IN THE SOUTHERN STREAM IN NW OLD MEXICO AND BRINGS TAIL END OF
S/W IN NRN STREAM THRU THE AREA BETWEEN 36-48 HRS.  THE NGM PHASES
THE NRN/SRN STREAMS AND BRINGS HIGH AMPLITUDE TROF THRU AREA.  THE
AVN PHASES THE NRN/SRN STREAM SOMEWHAT BUT THE DEVELOPS A CLOSED LOW
OVER THE SRN STREAM OVER THE RED RIVER VALLEY... THUS AVN MOS POPS
ARE MUCH HIGHER THAN ANYBODY ELSES TUESDAY NIGHT.  FORTUNATELY MODELS
ARE RELATIVELY CONSISTENT IN BRINGING SFC FRONT THRU ENTIRE FA BY TMW
MORNING AND BUILDING WK RIDGE IN FROM CNTRL ROCKIES.  IF AVN DOES
VERIFY... SFC CYCLOGENESIS COULD OCCUR CLOSE ENOUGH TO BRING A LITTLE
MORE MOISTURE BACK INTO SE OKLA BUT AM NOT INCLINED TO MAINTAIN POPS
IN THE SE ATTM. HOWEVER WILL NOT CLEAR SE ZONES AS RAPIDLY AS OTHERS
TMW/TMW NT.

COORD TUL.
