HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE ST LOUIS MO
440 AM CDT TUE JUN 30 2015

...EXCESSIVE RAINFALL MAY CAUSE FLOODING THE NEXT FEW DAYS...

THE WEATHER PATTERN IS AGAIN SETTING UP THE POSSIBILITY OF
EXCESSIVE RAINFALL ACROSS THE BI-STATE REGION OVER THE NEXT FEW
DAYS. A COLD FRONT DROPPING SOUTH THROUGH THE UPPER MIDWEST WILL
SLOW DOWN ACROSS CENTRAL MISSOURI AND ILLINOIS. AS WARM...MOIST
AIR PUSHES BACK OVER THIS FRONT LATE TONIGHT AND WEDNESDAY...LOOK
FOR WIDESPREAD SHOWERS AND THUNDERSTORMS TO DEVELOP.

WHILE THE HEAVIER RAIN IS STILL ALMOST A DAY AWAY...IT APPEARS
MUCH OF CENTRAL AND EASTERN MISSOURI INTO SOUTHERN ILLINOIS MAY
AVERAGE TWO TO THREE INCHES OF RAINFALL FROM LATE TONIGHT INTO
WEDNESDAY NIGHT. ADDITIONAL RAINFALL MAY PERSIST THURSDAY SOUTH OF
I-70...WITH THE HEAVIEST RAIN THURSDAY EXPECTED TO BE SOUTH OF THE
METRO ST. LOUIS AREA.

WITH MANY STREAMS STILL RUNNING HIGH...AND WITH THE GROUND
SATURATED FROM THE RECENT WET WEATHER...THIS RAINFALL COULD POST A
THREAT OF FLASH FLOODING...AND POSSIBLY WORSEN FLOOD IMPACTS ALONG
LARGER STREAMS AND RIVERS THAT ARE ALREADY FLOODED.

PEOPLE NEAR STREAMS SHOULD KEEP INFORMED OF THE LATEST WEATHER
INFORMATION AND REPORT ANY FLOODING TO THEIR LOCAL LAW
ENFORCEMENT. TRAVELERS ENCOUNTERING A FLOODED ROADWAY SHOULD
ALWAYS REMEMBER TO TURN AROUND...DON`T DROWN.
