HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE ST LOUIS MO
356 PM CDT MON JUN 15 2015

...HEAVY RAINFALL COULD BRING SIGNIFICANT FLOODING THIS WEEK...

A SERIES OF UPPER LEVEL DISTURBANCES AND A SLOW MOVING SURFACE
FRONT WILL INTERACT WITH VERY MOIST AIR TO PRODUCE SEVERAL ROUNDS OF
HEAVY RAINFALL PRODUCING THUNDERSTORMS THROUGH LATE WEDNESDAY. ON
THURSDAY THE REMNANTS OF A TROPICAL SYSTEM WILL TRACK ACROSS SOUTHERN
MISSOURI AND SOUTHERN ILLINOIS BRINGING AN ADDITIONAL ROUND OF HEAVY
RAINFALL.

BY LATE THURSDAY...WIDESPREAD RAINFALL TOTALS OF THREE TO SIX INCHES
ARE POSSIBLE ACROSS OUR REGION...WITH LOCALLY HIGHER AMOUNTS. THE
MAJORITY OF THIS RAINFALL IS EXPECTED LATE TUESDAY NIGHT INTO THURSDAY.

IF THE FORECAST RAINFALL IS REALIZED...THE RESULT WILL NOT ONLY
BE NEW RIVER FLOODING BUT ALSO ENHANCE ALREADY FORECAST FLOODING
ON BOTH THE MISSOURI AND MISSISSIPPI RIVER...WHERE SEVERAL POINTS
COULD RISE TO MODERATE OR EVEN MAJOR FLOOD LEVELS.

FLASH FLOODING WILL ALSO BE A HIGH CONCERN ON CREEKS...STREAMS...AND
SMALLER QUICK RESPONSE RIVERS.

THESE EXTENDED RAINFALL FORECASTS ARE LIKELY TO CHANGE...
NEVERTHELESS...THEY WARRANT CLOSE ATTENTION BY THOSE WHO LIVE IN
FLOOD PRONE AREAS AND HAVE INTERESTS ALONG STREAMS AND RIVERS.
