SFC TROF HAS NOT BEEN MVG MUCH IF AT ALL OVR THE PAST FEW HRS ALTHO
IT HAS MADE IT ACRS MUCH OF OSAGE AND PAWNEE CNTYS BFR XTNDG DOWN
INTO CNTRL OK. MEANWHILE A S/W IS CRNTLY MVG ACRS OK. THE COOLER
TEMPS ALOFT AND LIFT HV BEEN ENOUGH FOR AN ISOLD TSRA TO DVLP AHEAD
OF THE SFC BNDRY IN THE AREA OF BTR MOIST CONV AND INSTABILITY IN
SCNTRL OK. THIS TSRA EVENTUALLY COLLAPSED BUT ANOTHER STRM DVLPD ON
ITS OUTFLOW.

QUESTION IS WHETHER ADNTL PRECIP WL DVLP TNGT AND MV INTO FA AS THE
S/W CONTS OFF TO THE E AND ALSO IF/HOW MUCH THE SFC BNDRY WL MV EWD.
FORCING NOT TOO IMPRESSIVE BUT W/PLENTY OF LLVL MOISTURE AM HESITANT
TO MAKE MUCH CHG TO POPS. MAY LOWER THEM A LTL N OF I-40 WHERE
LIMITED INSTABILITY AND LTL LLVL CONV ARE FCST. MEANWHILE IT APRS
THAT THE SFC TROF WL CONT ON ITS VERY SLOW TREK. NEW ETA AND NGM ARE 
IN VERY GOOD AGREEMENT IN THE TROF POSN AT 12Z W/THIS FEATURE ONLY
MAKING IT INTO THE FAR ERN CNTYS OF OK.

SO WL MAKE SOME MINOR ADJS TO ZFP BUT OVRALL FCST SEEMS IN GOOD
SHAPE.
