225 PM CST TUE MAY 11 2004

...VERY HEAVY RAINFALL AND FLOODING POSSIBLE THURSDAY NIGHT THROUGH
SATURDAY OVER NORTH-CENTRAL TEXAS...

A SLOW MOVING UPPER LEVEL STORM SYSTEM CURRENTLY OVER THE ROCKIES
AND A SOUTHWARD MOVING COLD FRONT CURRENTLY OVER THE DAKOTAS WILL
BEGIN AFFECTING NORTHWEST AREAS OF NORTH TEXAS THURSDAY NIGHT
...THEN THE REMAINDER OF NORTH TEXAS FRIDAY AND FRIDAY NIGHT...WITH
SOUTHERN SECTIONS MAINLY AFFECTED GOING INTO SATURDAY. WITH COPIOUS
MOISTURE AVAILABLE FOR THIS SLOW MOVING STORM SYSTEM AND
INCREASINGLY ACTIVE JET STREAM TO INTERACT WITH...THE POTENTIAL FOR
VERY HEAVY RAINFALL WILL EXIST. DUE TO THE SLOW MOVEMENT...TRAINING
OF THUNDERSTORMS WITH VERY HEAVY RAINFALL IS POSSIBLE.

RAINFALL SINCE THE BEGINNING OF THE YEAR HAS RANGED FROM NEAR NORMAL
OVER NORTHERN PORTIONS OF NORTH TEXAS...TO WELL ABOVE NORMAL ACROSS
SOUTHERN SECTIONS OF NORTH TEXAS...NAMELY THE LEON RIVER BELOW LAKE
PROCTOR THROUGH GATESVILLE...THE BRAZOS RIVER VALLEY BELOW LAKE
GRANBURY...THROUGH WACO TO NEAR HEARNE AND THE TRINITY RIVER BASIN
FROM TRINIDAD TO LONG LAKE NEAR THE PALESTINE AREA. MANY OF THESE
AREAS ARE 8 TO 12 INCHES ABOVE NORMAL VALUES FROM JANUARY 1ST TO MAY
1ST. WACO WAS CURRENTLY 11.74 INCHES ABOVE NORMAL FOR THIS TIME
FRAME. SOIL MOISTURES ARE WET ACROSS A MAJORITY OF NORTH TEXAS.

AT THIS TIME...ABOUT MOST OF THE BRAZOS AND TRINITY RESERVOIRS ARE
NEAR OR AT THEIR CONSERVATION POOL LEVELS...SO ANY ADDITIONAL HEAVY
RAIN COULD RESULT IN THE RELEASE OF WATER INTO THE BASINS BELOW
THESE RESERVOIRS THAT MAY ALREADY BE FULL. LEON BASIN RESERVOIRS...
PARTICULARLY FROM LAKE PROCTOR NORTH ARE BELOW CONSERVATION POOLS AND
COULD USE THE ADDITIONAL RAINFALL...AS WELL AS OTHER LAKES OVER
WESTERN SECTIONS OF NORTH TEXAS THAT ARE 5 TO 15 FEET BELOW NORMALS.

THIS HYDROLOGIC AND FLOOD SITUATION WILL CONTINUE TO BE MONITORED
AND FINE TUNED THE NEXT SEVERAL DAYS AS MORE ACCURATE DATA BECOMES
AVAILABLE FOR FUTURE FORECASTS.

PERSONS LIVING IN NORTH TEXAS SHOULD MONITOR THESE FORECASTS FOR THE
POTENTIAL OF HEAVY RAINFALL CLOSELY THE NEXT 72 HOURS. BY THE END OF
THE WEEKEND...SATURATED SOILS ARE EXPECTED ACROSS THE REGION...AND
THE RISK OF STREAM AND RIVER FLOODING WILL REMAIN ELEVATED...EVEN
AFTER THE THUNDERSTORMS AND RAIN HAVE ENDED.

A SLOW MOVING UPPER LEVEL STORM SYSTEM APPROACHING FROM THE WEST AND A
SOUTHWARD MOVING COLD FRONT WILL AFFECT NORTH TEXAS THURSDAY AFTERNOON
THROUGH EARLY SATURDAY. ABUNDANT MOISTURE IN THE ATMOSPHERE...
COUPLED WITH ENERGY FROM THE SLOW MOVING STORM
SYSTEM...WILL BRING THE POTENTIAL FOR HEAVY RAINFALL.

NORTHERN PORTIONS OF NORTH TEXAS...TO WELL ABOVE NORMAL ACROSS SOUTHERN
SECTIONS...NAMELY THE LEON RIVER BELOW LAKE PROCTOR THROUGH
GATESVILLE...THE BRAZOS RIVER VALLEY BELOW LAKE GRANBURY...THROUGH WACO TO NEAR
HEARNE...AND THE TRINITY RIVER BASIN FROM TRINIDAD TO LONG LAKE NEAR
PALESTINE. MANY OF THESE AREAS ARE 8 TO 12 INCHES
ABOVE NORMAL.

AT THIS TIME...MOST OF THE BRAZOS AND TRINITY RESERVOIRS ARE NEAR OR AT
THEIR CONSERVATION POOL LEVELS...SO ANY ADDITIONAL HEAVY RAIN COULD
RESULT IN THE RELEASE OF WATER INTO NEARLY FULL BASINS. LEON BASIN
