...A FLASH FLOOD WARNING REMAINS IN EFFECT FOR WASHINGTON AND CLINTON
COUNTIES UNTIL 400 PM CDT...

AT 145 PM CDT...WEATHER SERVICE DOPPLER RADAR INDICATED A LINE OF
THUNDERSTORMS TRAILING SOUTHWEST FOR 100 MILES FROM THE CLINTON AND
WASHINGTON COUNTY LINE.

FALLEN NEAR INTERSTATE 64 AND NEAR OKAWVILLE. A NARROW LINE OF 
SHOWERS AND THUNDERSTORMS WILL MOVE NORTHEAST TOWARD THE AREA.
THE RAIN WILL INCREASE LATE THIS AFTERNOON. THE GROUND HAS BEEN

MUCH HAD LITTLE EFFECT AS FAR AS FLOODING.  HOWEVER...THE NEXT 
BATCH OF RAIN WILL INCREASE WATER RUNOFF AND CREATE THE LIKELIHOOD
OF DANGEROUS FLOODING. 

SOME AREAS NEAR THE CLINTON-WASHINGTON COUNTY LINE MAY END UP WITH
COPIOUS RAINFALL TOTALS.  RAINFALL AMOUNTS MAY LOCALLY REACH 6 TO
10 INCHES TONIGHT.  

OF ADDITIONAL SIGNIFICANCE...THE NATIONAL WEATHER SERVICE PLANS TO
ISSUE A FLOOD WATCH FOR TONIGHT AND SATURDAY WHICH WILL INCLUDE 
ALL OF SOUTHWEST ILLINOIS. CONDITIONS ARE RIPE FOR RAINS TO CONTINUE
HEAVY AT TIMES FOR THE NEXT 24 TO POSSIBLY 48 HOURS. KEEP ABREAST OF
