EVENT...BACKBUILDING LINEAR CELLS
.
SATELLITE ANALYSIS AND TRENDS...QUICKLY DVLPG W-E LINE OF STORMS ACROSS
S AR APPEARS TO BE ANCHORED ALONG THE MILLER/LITTLE RIVER COUNTY BORDER
AND HAVE SHOWN SOME SIGNS OF BACKBUILDING INTO EXTREME NE TX. ADDTL
CELLS WHICH HAVE FORMED E AND SE OF THOSE CELLS THAT ARE PRODUCING
HVY RAINFALL AND THOUGH MOVING LOOK AS IF THEY COULD BACKBUILD AS
WELL TO THE W. LIGHTNING DATA SHOWS VERY COMPACT STRIKES ACROSS
OUACHITA/CALHOUN/BRADLEY COUNTIES..HEMPSTEAD/N MILLER COUNTIES..AND
CLAIBORNE/WEBSTER PARISHES IN N LA INDICIATING THE INTENSE NATURE OF
THE STORMS..WHICH MAY CONTAIN HAIL.
.
LOW LVL MOISTURE CAN BE SEEN WELL ON IR MOVING INTO SE TX/LA AND
IT IS ALONG THE STNRY FRNT IN S AR/N LA..JUST E OF A SFC LOW..WHERE
THE CELLS HAVE FORMED AND ARE CAPITALIZING ON THE RICH MOISTURE FEED
OFF THE GULF. 00Z PW ANALYSIS INDICATED A POCKET OF 1" PW'S AT SHV
AND SFC ANALYSIS SHOWS DWPTS IN THE HIGH 50'S-LOW/MID 60'S ALONG THE
TX/LA BORDER. ADDITIONALLY..LLJ HAS DRAMATICALLY INCREASED OVER THE
LAST 2 HRS FROM 20KTS TO 40KTS PER LOCAL VWPS. ESTIMATE THAT RAINFALL
RATES OF 0.5-1"/30 MIN ARE OCCURRING WITH THESE CELLS AND IF THEY
STAY OVER THE SAME COUNTIES OR TRAIN ALONG THE STNRY BNDRY..FFG WILL
BE QUICKLY REACHED. A CELL MERGER APPEARS TO HAVE JUST OCCURRED INVOF
OUACHITA/CALHOUN COUNTIES WHERE MANUEL STLT ESTIMATES INDICATE AROUND 2"
OF RAINFALL OVER THE PAST HR. WILL CONTINUE TO MONITOR.
