EVENT...ADDITIONAL HVY RAINS WITH SLOW MOVING CONVECTION
.
SATELLITE ANALYSIS AND TRENDS...CONVECTION HAS DEVELOPED JUST AHEAD OF
THE SFC COLD FRONTAL BOUNDARY ACROSS PORTIONS OF NE AND E OK/NW AR/AND
SW MO.  THESE CELLS HAVE RAPIDLY INTENSIFIED OVER THE PAST HR OR SO WITH
IR IMAGERY SHOWING COLDEST CLOUD TOPS NEAR -64C ALONG OK/AR BORDER..INVOF
WASHINGTON COUNTY AR.  THESE CELLS ARE MOVING VERY SLOWLY TO THE ESE
AT THIS TIME AND SEVERAL CELL MERGERS HAVE ALREADY OCCURRED PER LATEST
VIS ANIMATION.  CONCERN IS FOR ADDITIONAL CELL MERGERS TO OCCUR AS THIS
LINE OF STORM SLOWLY PROGRESSES TO THE ESE AND INTO NORTH-CENTRAL AR OVER
THE COURSE OF THE NEXT 1-3 HRS.  THIS AREA WAS ALREADY HIT BY HVY RAINS
WITH THE EARLIER PASSAGE OF THE MCS THAT HAS NOW MOVED OVER SE AR AND
INTO W MS..SO MORE HVY RAIN IS NOT SOMETHING THIS AREA WANTS TO SEE.
ADDITIONAL RAINFALL OF 1-2" WITH LOCALLY HIGHER AMOUNTS SHOULD BE
EXPECTED FROM CARROLL..MADISON..JOHNSON COUNTIES EASTWARD TO SHARP AND
INDEPENDENCE COUNTIES IN NORTH-CENTRAL AR WITH THESE SLOW MOVING CELLS.
RAINFALL RATES ASSOCIATED WITH THESE CELLS MAY REACH UP TO 1.0-2.0"/HR
BASED UPON MANUAL STLT ESTIMATE TECHNIQUE.
