NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
312 AM EDT WED JUL 24 2013
 
AREAS AFFECTED...EASTERN OK/WESTERN AR... 
 
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE 
 
VALID 240711Z - 241011Z
 
SUMMARY...TRAINING CELLS/BACKBUILDING CONVECTION REMAIN POSSIBLE
ACROSS SECTIONS OF EASTERN OK/WESTERN AR DURING THE NEXT COUPLE OF
HOURS.

DISCUSSION...OVER THE COURSE OF THE LAST FEW HOURS...THE ONCE
SEPARATE REGIONS OF CONVECTION HAVE CONSOLIDATED INTO A COMPLEX OF
MODERATE TO HEAVY THUNDERSTORMS. THE MCS WHICH HAD BEEN OVER
CENTRAL KS HAS MERGED WITH THE QUASI-STATIONARY PRECIPITATION
ACROSS AR. WHILE THE MCS HAS AIDED IN DOWNSTREAM PROPAGATION OF
THE RAINFALL...THERE ARE STILL MANY ASPECTS OF MERGING CELLS NOTED
ON THE RADAR. CONCERN REMAINS IN SUCH PROCESSES CONTINUING AS
CLOUD TOPS HAVE SHOWN NO SIGNS OF WARMING JUST YET. WHILE
CONVECTIVE INHIBITION HAS BECOME PREVALENT DURING THE OVERNIGHT
COOLING PROCESSES...ENOUGH MUCAPE HAS BEEN AVAILABLE TO MAINTAIN
ELEVATED CONVECTION. OVERALL...THE GROUNDS REMAIN RATHER SATURATED
AS RADAR ESTIMATES SUGGEST A WIDESPREAD AREA OF 2 TO 4 INCHES OF
RAIN HAS FALLEN FROM SOUTH-CENTRAL KS DOWN ALONG THE OK/AR BORDER
SINCE 00Z. CURRENT RAIN RATES SUGGEST ANOTHER 1 TO 2 INCHES WITH
ISOLATED HIGHER AMOUNTS MAY BE POSSIBLE OVER THE AFFECTED REGION.
