SATELLITE ANALYSIS AND TRENDS...BAND OF W-E CNVTN EXTENDING FM VERMILION
PARISH THRY ST BERNARD PARISH HAS REMAINED NRLY STNRY WHILE INDIVIDUAL
TSTMS HAVE BEEN MOVG E. CLOUD TOPS HAVE BEEN STEADILY COOLING. VIS IMAGERY
SHOWS CU OVER GULFMEX STREAMING NEWD ACRS THE SRN LA COAST..ESP ACRS THE
AREA FM VERMILION TO TERREBONNE PARISHES. THIS ALONE WOULD HELP MAINTAIN
THE STRENGTH OF THE CNVTN. BUT THERE ARE OTHER FACTORS AS WELL. ONE IS
THE SUBTROPICAL JET STREAK MOVG NEWD ACRS NW GULFMEX. LATEST GOES WIND
ANALYSIS AND WV IMAGERY ANIMATION HAS LEADING EDGE NRN EDGE OF SPEED MAX
AIMED FOR S CENTRAL/SE LA COAST. THIS SHOULD RESULT IN INCR IN UPWARD
MOTION. OTHER FACTORS ARE HIGH PW AND INSTABILITY OVER THE DISCUSSION
AREA..PER GOES SOUNDER IMAGERY.
.
IN ADDITION TO THE CURRENT PARISHES WITH CNVTN..THERE IS ALSO THE
POSSIBILITY THAT SOME DEVELOPMENT/BACKBUILDING MAY OCCUR OVER CAMERON
PARISH. A NARROW CU LN EXTENDS SWWD FM THE CNVTN ACRS CAMERON PARISH. VORT
NR ACT IS MOVG SE AND MAY ACTIVATE CNVTN OVER SE/E TX AND SW LA.
.
CURRENT STLT TRENDS INDICATE THAT CELL TRAINING AND MERGERS CAN
BE EXPECTED THIS AFTN..AND WITH HIGH PWS AND DEW POINTS VERY HVY
RAIN CAN OCCUR IN A SHORT PERIOD OF TIME. WITH THE CELL TRAINING AND
MERGERS..RAINFALL TOTALS OF 2-4" ARE LIKELY..WITH SOME HIGHER AMOUNTS
PSBL.
