EVENT...HEAVY RAIN SHOULD CONTINUE TO AFFECT AREA OF NE LA/W CENT
TO CENT MS FOR AT LEAST THE NEXT HOUR WHERE WARNINGS ARE ALREADY IN
PLACE. POTENTIAL EXISTS FOR SIGNIFICANT CELL MERGERS ACROSS SW TO S CENT
LA WITH VERY INTENSE RAINFALL RATES TO OVER 3"/HR.
.
SATELLITE ANALYSIS AND TRENDS...IR LOOP THROUGH 0945Z SHOWS SW TO NE
ORIENTED AREA OF RELATIVELY COLDER CLOUD TOPS STILL AFFECTING APPROXIMATE
AREA FROM RICHLAND/W CARROLL PARISHES OF NE LA TO YAZOO/HOLMES COUNTIES OF
CENT MS NEAR EARLIER ANALYZED SFC TROF. AUTOMATED SATELLITE ESTIMATING
TECHNIQUES ARE INDICATING LOCALIZED TOTALS OVER 3" ALONG THIS AXIS
PARTICULARLY NEAR THE LA-MS-AR BORDER. GIVEN THE PERSISTENCE OF THIS
ACTIVITY CERTAINLY BELIEVE EVEN HIGHER TOTALS THAN THIS MAY HAVE ACTUALLY
OCCURRED. WITH THE PRIMARY LINE STILL BACK OVER S CENT AR/N CENT LA
EXPECT CELLS TO CONTINUE TO MOVE OVER THIS REGION FOR THE NEXT HALF
HOUR TO HOUR AND LIKELY EVEN LONGER FOR SPOTS FARTHER TO THE EAST IN
CENT MS. GIVEN THESE TRENDS, AT LEAST ANOTHER 1-2" SEEMS LIKELY.
.
FOR SW TO S CENT LA...VERY COLD TOPPED CELLS HAVE FORMED OUT AHEAD
OF THE MAIN LINE ACROSS THE SW TO S CENT PORTIONS OF THE STATE WITH
AUTOMATED SATELLITE ESTIMATES ALREADY SHOWING TOTALS OF WELL OVER 1" FOR
CAMERON/VERMILION PARISHES. IR LOOP SHOWS LIKELY MERGERS UPCOMING BETWEEN
THESE CELLS, THE MAIN LINE MOVING IN FROM THE WEST, AND MORE ACTIVITY
SPREADING NORTHWARD FROM THE GULF OF MEXICO. WITH RECENT MICROWAVE DATA
SHOWING OVER 2" PWS ALONG COASTAL SE TX/S LA BELIEVE RAIN RATES IN EXCESS
OF 2"/HR ARE LIKELY WITH THE POSSIBILITY OF LOCALIZED RATES WELL OVER
3"/HR WITH THE STRONGEST CELLS AND CELL MERGERS ACROSS SW TO S CENT LA.
