SATELLITE ANALYSIS AND TRENDS...VERY STRONG SLOW MOVING E-W ORIENTED
CELLS HAVE BEGAN THEIR PROGRESSION INTO N LA THOUGH CONTINUED
BACKBUILDING/REINFORCEMENT BY NEW CELLS HAS MADE THEIR MOVEMENT SEEM
NEARLY STNRY ON IR STLT. SOME CLOUD TOP WARMING HAS OCCURRED OVER THE
LA/TX BORDER AND THE COMPLEX OF STORMS TO THE N IN SE OK/WRN AR HAS
WARMED BY OVER 10 DEG C OVER THE PAST 2 HRS. VIS IMAGERY SHOWS THE VIRTUAL
COLLAPSE OF THE NRN COMPLEX TO BE THE RESULT OF AN OUTFLOW BNDRY MOVING
OUT TO THE W THROUGH NE TX/SE OK. LIGHTNING DATA SHOWS STORMS OVER THE
PAST 1-2 HRS HAVE BECOME MUCH MORE SCATTERED WITH THE EXCEPTION OF TWO
AREAS NEAR THE LA/TX BORDER..FROM CHEROKEE/ANDERSON COUNTIES IN TX TO
CADDO/DE SOTO/RED RIVER PARISHES IN LA..AND ALSO FROM TRINITY/HOUSTON
TO NACOGDOCHES COUNTY AND E INTO SABINE/NATCHITOCHES PARISHES.
.
OBJECTIVE ANALYSIS INDICATES TWO AREAS WHERE RICH MOISTURE IS FLOWING
FROM THE TX GULF COAST..ONE INTO THE TAIL END OF THE STRONG CELLS IN E
TX WHICH HAS ALLOWED THEM TO CONTINUE TO BACKBUILD/REFORM TO THE W/SW
AND ANOTHER RUNNING NWD ALONG THE STNRY FRNT JUST E OF KDAL TO NEAR
KOUN. OUTFLOW BNDRY MENTIONED ABOVE MAY YET SPARK SOME NEW CNVTN ALONG
THE FRNT AS THEY INTERACT BUT SOME WEAK STABILITY IS ALSO IN PLACE PER
GOES SOUNDER FOR THE MOMENT.
.
MERGERS BETWEEN THE NUMEROUS AMOUNTS ALONG WITH THE NEARLY STNRY NATURE OF
COLDEST TOPS DUE TO TRAINING OF CELLS HAS RESULTED IN MANUALLY ESTIMATED
4-6" FROM 17-19Z FROM S SHELBY/N SAN AUGUSTINE COUNTIES INTO SABINE
PARISH. AUTOMATED STLT ESTIMATES ARE MUCH LESS WITH 2.7" OVER SABINE
COUNTY/SABINE PARISH FOR 3 HRS ENDING 1845Z BUT ARE UNDERESTIMATING. CELLS
SHOULD CONTINUE TO FORM ON THE WRN END OF THESE LINES OF CELLS. WILL
CONTINUE TO MONITOR.
