MESOSCALE PRECIPITATION DISCUSSION 0055...CORRECTION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
916 AM EDT TUE MAY 13 2014
 
AREAS AFFECTED...SOUTHERN TX 
 
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE 
 
VALID 131313Z - 131513Z
 
SUMMARY...THUNDERSTORMS WITH VERY HEAVY RAINFALL ARE EXPECTED TO
CONTINUE ACROSS SOUTHERN TX FOR ANOTHER 2-3 HOURS, BECOMING MORE
ISOLATED IN NATURE AFTER 15Z.  UNTIL THEN, REGIONAL FLASH FLOODING
IS POSSIBLE.

DISCUSSION...CURRENT RADAR IMAGERY COMBINED WITH A STRONG SIGNAL
IN THE 00Z NAM CONEST AND MASS FIELDS FROM THE 00Z ARW AND 11Z RAP
INDICATE THAT HEAVY RAINFALL CONTINUES TO FALL ACROSS THE LOWER
RIO GRANDE VALLEY, AND SHOULD DO SO FOR ANOTHER COUPLE HOURS
BEFORE HEAVY RAINFALL CORES BECOME LESS NUMEROUS AND LESS
SIGNIFICANT.  850 HPA INFLOW AND AVAILABLE CAPES WEAKEN
SIGNIFICANTLY BY 15Z.  UNTIL THEN, HOURLY RAINFALL RATES OF 2-3"
IN THE STRONGER STORMS COULD LEAD TO LOCAL AMOUNTS OF 3-5" WHICH
COULD LEAD TO REGIONAL FLASH FLOODING.
