AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1003 PM CDT WED OCT 30 2013

.DISCUSSION...

WE HAVE UPDATED THE FLASH WATCH TO INCLUDE DEEP EAST TEXAS...NO
CHANGES WERE MADE TO THE VALID TIME. WIDESPREAD RAIN SHOWERS AND
ISOLATED THUNDERSTORMS CONTINUE ACROSS THE AREA THIS EVENING. THE
THUNDERSTORM ACTIVITY HAS MAINLY BEEN JUST SOUTH OF I20 IN EAST
TEXAS...AND THIS IS WHERE THE HIGHEST RAINFALL TOTALS ARE LOCATED.
RADAR ESTIMATES HAVE BEEN FAIRLY CLOSE TO ASOS READINGS...WITH 1
TO 2 INCHES BEING COMMON ACROSS THE AREA...WITH ISOLATED AMOUNTS
NEAR 4 INCHES. A WARM FRONT IS LOCATED JUST SOUTH OF I20 AND THE
THUNDERSTORM ACTIVITY SHOULD CONTINUE TO BE FOCUSED ON THIS
BOUNDARY UNTIL THE COLD FRONT COMES INTO PLAY AFTER MIDNIGHT.
FORCING ALONG THE COLD FRONT SHOULD HELP INCREASE MORE THUNDERSTORM
ACTIVITY ACROSS THE AREA LATER TONIGHT. POPS HAVE BEEN RAISED IN
THE EVENING PACKAGE ALONG WITH LOWERING TEMPS TO NEAR OR JUST
BELOW CURRENT READINGS. THE UPDATED ZFP WILL BE OUT SHORTLY.
