SATELLITE ANALYSIS AND TRENDS...CLUSTER OF TSTMS CONTINUES TO PUSH SSEWD
ACROSS NORTH AND EAST AR THIS AFTERNOON.  LATEST VIS IMAGERY INDICATES
THAT SOME OF EMBEDDED CELLS MAY MERGER WITH ANOTHER AREA OF TSTMS THAT
HAS DEVELOPED AHEAD OF THE MAIN BATCH OF STORMS OVER LINCOLN..DESHA..DREW
COUNTIES IN SE AR. THESE RECENTLY DEVELOPED CELLS SEEM TO BE RELATIVELY
STATIONARY AND THE APPROACHING MAIN BATCH OF TSTMS IS APPROACHING FROM
THE NORTH.  IT SEEMS VERY LIKELY THAT IN THE NEXT 15-30 MINS CELL MERGERS
BETWEEN THESE TWO FEATURES WILL OCCUR RESULTING IN AN INCREASE IN CELL
INTENSITY AND HIGHER RAINFALL RATES.  AREA FOR IMMEDIATE CONCERN WHERE
MERGERS MAY DEVELOP ARE INVOF ARKANSAS..PHILLIPS..DESHA COUNTIES IN AR
AND BOLIVAR..COAHOMA.. QUITMAN..TALLAHATCHIE COUNTIES IN NE MS.  RAINFALL
RATES MAY REACH UP TO 1.2-2.2"/HR WITH THE HIGHER RATES ACCOUNTING FOR
CELL MERGERS.  HYDROESTIMATOR 1-HR AMOUNTS ENDING AT 1945Z OVER WHITE
AND LONOKE COUNTIES IN CENTRAL AR SHOW MAX OF 0.9"..SO THIS SEEMS TO
BE IN LINE WITH CURRENT THINKING THAT WITH CELL MERGERS RATES WILL BE
HIGHER THAN 1.0"/HR.
