EVENT...SLOW MOVING CONVECTION IN LOW FFG VALUES
.
SATELLITE ANALYSIS AND TRENDS...WEDGE OF CONVECTION OVER S SUTTON/N
EDWARDS COUNTY HAS REMAINED NEARLY STATIONARY OVER THE LAST
1-2HRS WITH VERY COLD TOPS TO -70C.  THIS WEDGE IS TUCKED ON THE
PEAK OF THE SUBTROPICAL JET AND SOUTH OF OUTFLOW JET STREAK FROM NM
CONVECTION... SHAPING THE CONVECTION INTO THE WEDGE.  WITH SFC EASTERLIES
AND 850 SSELY FLOW OF HIGHER MOISTURE (65-70 TDS AND 1.4-1.5" PW) THE
CELLS ALONG THE QUASI-STATIONARY BOUNDARY CONTINUE TO BE FED TO AID
RAIN RATES OF 1.5"/HR.  SINCE THE CELL HAS NOT MOVED MUCH IN THE LAST
HOUR...TOTAL WOULD APPROACH/EXCEED FFG VALUES.

LATEST G-12 IMAGE SHOWS A SLIGHT SHIFT OF CELL INTO EDWARDS PROBABLY
DUE TO A SUFFICIENT DEVELOPMENT OF COLD POOL/DOWNDRAFT...MOST LIKELY
INCREASING FORWARD SPEED SSE SIMILAR TO COMPLEX SW OF SAT. ADDITIONAL
COOLING OF UPSTREAM CELL OVER SE CROCKETT/NE VAL VERDE COUNTY...WILL
SHIFT FOCUS OF FF THREAT...IF IT TOO CAN REMAIN NEARLY STATIONARY ALONG
THE BOUNDARY.
