NESDIS IS CONTINUING TO ACCEPT APPEALS ON THE RETIREMENT OF THE SPENES
PRODUCT.  APPEALS CAN BE SUBMITTED BY EMAILING JOHN.SIMKO@NOAA.GOV
.
EVENT...UPDATE TO EARLIER SPENES MESSAGE FOR ONGOING HEAVY RAIN THREAT
ACROSS NW TX.
.
ANALYSIS AND OUTLOOK...THE LARGE MCS CURRENTLY OVER SERN PANHADLE OF
TX CAN BE SEEN SPANNING FROM JUST N OF KSNK TO KLTS IN SW OK WITH
ADDITIONAL CONVECTION  INITIATING ALONG A REMNANT OUTFLOW BOUNDARY
OVER SWERN OK. COLD POOL FORMATION OVER NW TX HAS ALLOWED FOR RECENT
EASTWARD PROPAGATION/ACCELERATION WITH THIS LINE THOUGH MEAN FLOW IS
STILL FAVORING SOME TRAINING ALONG THE LINE FROM SW TO NE.  A LLJ FROM
THE SSE HAS ALLOWED BETTER MOISTURE FROM S AND SE TX TO ADVECT NORTHWARD
ACCORDING TO BLENDED TPW PRODUCT/GOES SOUNDER/GPS NETWORK WITH PW VALUES
OF AT LEAST 1.5" AND HIGHER FROM N CENT TX TO S AND SE TX.  GOES SOUNDER
PRODUCT ANIMATION SHOWS SIGNIFICANT INSTABILITY AXIS HAS ALSO SURGED
N FROM S AND SE TX WITH CAPE VALUES REACHING AT LEAST 4000-5000 J/KG
THROUGHOUT MOST OF E TX WHICH CERTAINLY WOULD IMPLY THE LINE MAINTAINING
ITSELF AS IT MOVES EASTWARD WITH RAINFALL EFFICIENCY ALSO POTENTIALLY
INCREASING SOMEWHAT AS THE LINE MOVES EAST AND ENCOUNTERS THE BETTER
MOISTURE AXIS. ALSO, AS LLJ STRENGTHENS INTO THE NIGHTTIME HOURS AND
BEGINS TO VEER CONVECTIVE INITIATION IS POSSIBLE AHEAD OF THE MAIN LINE
NEAR REMNANT OUTFLOW BOUNDARY IN N CENT-NE TX. CURRENT ANALYSIS OF LOW
LEVEL CONVERGENCE AND VISIBLE IMAGERY STILL INDICATES SOME EVIDENCE OF
THIS BOUNDARY STRETCHING FROM JUST N OF SHREVEPORT LA TO THE RED RIVER
REGION DUE N OF DALLAS-FT WORTH. THERE IS DEFINITELY A CONCERN THIS
SITUATION WILL LEAD TO A GREATER THREAT FOR TRAINING ACROSS N CENT TX
LATER THIS EVENING THOUGH CONFIDENCE IN THIS SCENARIO IS NOT VERY HIGH.
