EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 345 PM CDT THU MAY 9 1996 ATMOSPHERE MAY BE PREMIERING ITS OWN VERSION OF "TWISTER" TONIGHT. WDLY SCT STRONG/SVR TRWS CONTINUE OVER NE OK ALONG AND AHEAD OF THE FRONT. APPEARS AS IF THE CAP IS HOLDING OVER SE OK WHERE BREAKS IN THE CLOUDS HAVE ALLOWED TEMPS TO RISE INTO THE LOW TO MID 80S. STILL LOOKING FOR THE CAP TO BREAK OVER SE OK HOWEVER GOOD LIFTING MAY BE CONFINED TO THE COLD FRONT WHICH STILL REMAINS JUST NORTH OF TUL (AS OPPOSED TO 12Z ETA FCST PSN ON THE RED RIVER AT 00Z). WIND PROFILE STILL NOT OPTIMAL FOR TORNADIC DEVLOPMENT...HOWEVER MID LEVEL WINDS HAVE INCREASED TO 40+ KTS WHICH MAY INDICATE BETER ENVIRONMENT FOR RFD FORMATION. ANALYSIS OF SFC/VAD/PROFILER WINDS SHOWS HELICITY VALUES AOB 100 ACROSS THE WARM SECTOR. EXPECT RW-/TRW TO CONTINUE INTO TONIGHT...ESP OVER SE OK AND NW AR EVEN BEHIND THE FRONT. BASED ON CURRENT TRENDS IN DEVELOPMENT OF TRW AND ABUNDANT LOW LEVEL MOISTURE/MOISTURE ADVECTION...WILL ISSUE FFW FOR AREAS SOUTH OF A GROVE TO HENRYETTA LINE. BACK EDGE OF PRECIP SHOULD BE ALONG H7 TROUGH AXIS WHICH IS FCST TO MOVE THROUGH AROUND SUNRISE. AS HINTED EARLIER...ETA MODEL IS MUCH TOO FAST WITH THE FRONT SO NGM/AVN USED FOR THIS FCST. AVN TEMPS LOOK A LITTLE TOO COOL TOMORROW WITH SUNSHINE TOMORROW SO WENT WITH WARMER NGM TEMPS. NO PCGRIDDS DATA TO LOOK AT TODAY. AFOS GRAPHICS FROM NGM AND AVN SHOW DIFFERENCE IN WHERE STALLED FRONT IN TEXAS ENDS UP SAT NIGHT AND SUN. NGM GUIDANCE HAS ZERO POPS FOR SAT NIGHT/SUN WHILE AVN HAS 30-40 WITH A WARM FRONT DEVELOPING. FOR NOW WILL LEAVE OUT POPS ASSUMING FRONT AND MOISTURE WILL CONTINUE SWD INTO THE GULF COAST IN STRONG NWLY FLOW. CONVECTION ALONG FRONT SHOULD ALSO HELP ACCELERATE ITS SWD MOMENTUM.
