HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE ST LOUIS MO
117 PM CST TUE DEC 22 2015

...HEAVY RAINFALL AND FLOODING POSSIBLE THIS HOLIDAY WEEKEND...

AN ACTIVE WEATHER PATTERN WILL BRING A PROLONGED PERIOD OF RAIN TO
THE REGION BEGINNING CHRISTMAS NIGHT...CONTINUING THROUGHOUT THE
WEEKEND...AND CONTINUING INTO EARLY NEXT WEEK. EARLY ESTIMATES
ARE THAT WIDESPREAD RAINFALL AMOUNTS OF 3 TO 6 INCHES CAN BE
EXPECTED...WITH LOCALLY HIGHER AMOUNTS.

THE SOIL MOISTURE ACROSS THE REGION IS CURRENTLY RUNNING 1 TO 2
INCHES ABOVE NORMAL AND LOCAL RIVERS AND CREEKS ARE AT OR ABOVE
NORMAL STAGE AND FLOW FOR THIS TIME OF YEAR. IN ADDITION...THE
LACK OF VEGETATION IN THE DORMANT WINTER SEASON INCREASES THE
POTENTIAL FOR RUNOFF FROM EXCESSIVE RAINFALL. THESE ANTECEDENT
CONDITIONS...COMBINED WITH THE POTENTIAL OF VERY HIGH RAINFALL
TOTALS...COULD LEAD TO ADDITIONAL RIVER FLOODING...AND/OR A
WORSENING OF THE ONGOING FLOODING ALONG THE MISSISSIPPI AND
ILLINOIS RIVERS.

THOSE WITH INTERESTS ALONG AREA RIVERS SHOULD STAY TUNED TO THE
LATEST WEATHER AND RIVER FORECASTS FROM THE NATIONAL WEATHER
SERVICE IN ST. LOUIS.
