A BUSY NIGHT HAS TURNED INTO A BUSY DAY. RAINFALL REPORTS IN EXCESS
OF 6 INCHES HAVE BEEN RECEIVED FROM THE MESONET AT WESTVILLE AND
FROM COOP OBSERVER AT TAHLEQUAH. ANLYS OF MRNG UA DATA SHOWS WNDS
AOA 700 MB ALL PARALLEL TO CURRENT LINE OF CONVECTION.
THEREFORE...SLOW MOVEMENT WL STILL BE THE RULE THROUGH THIS MRNG.
WV IMGRY SHOWS ANOTHER S/W NOW OVR TX PNHDL AND WRN OK THAT WL
SWING EWD THIS AFTN. IT MAY FINALLY SHIFT ACTIVITY TO THE EAST AND
END TRAINING OF CELLS AND REDUCE THE FLOODING THREAT. HOWEVER...THE
ASSOC MID LVL DRYING ALONG WITH 50+ KT MID-LVL JET STREAK WL BE THE
IMPETUS FOR MORE SVR WX. AM CONCERNED ABOUT THE FSM AREA WHERE LOW-
TOPPED CONVECTION HAS BEEN FIRING UP AHEAD OF MAIN TSRA LINE. AS
S/W APPROACHES...AND MSTR INFLOW CONTS WITH INCRG DIRECTIONAL WIND
SHEAR...THIS CUD BE WHERE MORE SVR WX GETS STARTED THIS AFTN.

WL NOT CHANGE AREAL COVERAGE OF FFA. THE NRN COUNTIES IN THE WATCH
AREA MAY NOT NECESSARILY RECEIVE ANY MORE HEAVY RAIN...BUT AFTER 2-
3 INCHES...IT WUD NOT TAKE MUCH MORE RAIN TO CAUSE MORE PROBLEMS.
WL ISSUE FFS TO UPDATE THE SITUATION. SE OK WL LIKELY SEE EXCESSIVE
RAINFALL THIS AFTN AS FWD HAD A 12Z 850 MB DWPT OF 17C AND
IMPRESSIVE INSTABILITY PARAMETERS. WELL-DEFINED THETA-E AXIS WAS
