PROBABILISTIC HYDROLOGIC OUTLOOK  
NATIONAL WEATHER SERVICE ST. LOUIS MO  
342 PM CST THU FEB 13 2020  
   
..SPRING FLOOD AND WATER RESOURCES OUTLOOK NUMBER 1
 
 
...SIGNIFICANT FLOODING LIKELY ALONG THE MISSISSIPPI AND MISSOURI  
RIVERS...   
..MINOR FLOODING LIKELY ALONG MOST LOCAL STREAMS
 
 
THIS OUTLOOK USES THE TERM ST. LOUIS SERVICE AREA TO REFER TO THE  
MISSISSIPPI RIVER FROM ABOVE CANTON MISSOURI TO ABOVE CAPE GIRARDEAU  
MISSOURI, THE MISSOURI RIVER ABOVE JEFFERSON CITY MISSOURI TO ITS  
CONFLUENCE WITH THE MISSISSIPPI RIVER, THE ILLINOIS RIVER DOWNSTREAM  
FROM BEARDSTOWN ILLINOIS TO ITS CONFLUENCE WITH THE MISSISSIPPI  
RIVER, AND FOR TRIBUTARY RIVERS IN EASTERN MISSOURI, AND WEST  
CENTRAL AND SOUTHWEST ILLINOIS.  
 
THE ONLY ONGOING FLOODING ANYWHERE WITHIN THE ST. LOUIS SERVICE AREA  
IS ALONG THE KASKASKIA RIVER AT BOTH VANDALIA AND AT THE TAILWATER  
GAGE OF CARLYLE DAM. OTHERWISE, THE PROBABILITIES WITHIN THIS  
OUTLOOK ARE NOT SKEWED BY ANY ONGOING FLOODING, THOUGH INITIAL FLOWS  
ARE UNUSUALLY HIGH FOR THIS TIME OF YEAR.  
 
THIS OUTLOOK IS BASED ON CURRENT STREAMFLOWS AND SOIL MOISTURE OVER  
THE AREA, AND UPSTREAM SNOWPACK IN THE MISSISSIPPI, MISSOURI, AND  
ILLINOIS RIVER BASINS. THE STATISTICS ARE BASED ON ABOUT 60 YEARS OF  
HISTORICAL RAINFALL AND STREAM CRESTS. MORE THAN NORMAL RAINFALL  
COULD CAUSE HIGHER-THAN-EXPECTED CRESTS AT INDIVIDUAL FORECAST  
LOCATIONS, WHILE LESS THAN NORMAL RAINFALL COULD KEEP STREAMS FROM  
REACHING "LIKELY" CRESTS.  
 
THE LARGER RIVERS, PARTICULARLY THE MISSISSIPPI AND MISSOURI RIVERS,  
HAVE EXPERIENCED WELL ABOVE NORMAL STREAMFLOW THROUGH MOST THE PAST  
WINTER. THIS IS PROVIDING A HIGH STARTING POINT FOR THESE RIVERS TO  
ACCEPT FUTURE RUNOFF. IN ADDITION, IN THE WAKE OF LAST YEAR'S  
HISTORIC FLOODING ALONG BOTH RIVERS, SOIL MOISTURE IN BOTH BASINS  
REMAINS VERY HIGH, PARTICULARLY ACROSS THE UPPER MIDWEST AND  
NORTHERN PLAINS. THIS WILL PREVENT THE LAND AREAS FROM ABSORBING  
MUCH FUTURE SNOWMELT OR RAINFALL, AND THIS SITUATION WILL NOT CHANGE  
UNTIL AFTER THE SPRING THAW, WHEN PROLONGED WARM AND DRY WEATHER MAY  
PROVIDE AN OPPORTUNITY FOR THESE SOILS TO DRY OUT. FINALLY,  
SNOWPACK AND SNOW WATER EQUIVALENT IN THIS SNOWPACK IS WELL ABOVE  
AVERAGE ACROSS MUCH OF WISCONSIN AND MINNESOTA INTO THE EASTERN  
DAKOTAS. THIS SNOWPACK IS MOST OMINOUS FOR THE MISSISSIPPI RIVER  
OUTLOOK, WHILE THE LOWER MISSOURI RIVER BASIN'S SNOWPACK IS LARGELY  
BELOW NORMAL. THIS IS PROVIDING WELL ABOVE NORMAL CHANCES FOR  
SIGNIFICANT FLOODING ALONG THE MISSISSIPPI RIVER, WITH MODERATE  
FLOODING CONSIDERED AS LIKELY AT MOST FORECAST LOCATIONS. IN FACT,  
MAJOR FLOODING IS CONSIDERED LIKELY AT SAVERTON LOCK AND DAM,  
CLARKSVILLE LOCK AND DAM, AND CHESTER, ILLINOIS. ALONG THE MISSOURI  
RIVER, MODERATE FLOODING IS LIKELY AT JEFFERSON CITY AND HERMANN,  
AND MINOR FLOODING IS LIKELY AT CHAMOIS, WASHINGTON, AND ST. CHARLES.  
 
FOR LOCAL BASINS, THE CHANCES FOR FLOODING ARE AT MOST LOCATIONS  
THROUGHOUT THE ST. LOUIS SERVICE AREA ARE ABOVE AVERAGE. THE  
EXCEPTION IS ACROSS CENTRAL MISSOURI, WHERE FLOOD PROBABILITIES ARE  
CLOSER TO NORMAL. MINOR FLOODING IS LIKELY ALONG THE FABIUS RIVERS,  
THE NORTH RIVER, THE MIDDLE FORK SALT RIVER, THE CUIVRE RIVER, THE  
OSAGE RIVER, THE MERAMEC RIVER, THE BOURBEUSE RIVER, THE BIG RIVER,  
THE MOREAU RIVER, THE LA MOINE RIVER, AND THE KASKASKIA RIVER. SOIL  
MOISTURE AND WINTERTIME PRECIPITATION HAVE LEFT THESE AREAS WITH  
MOIST SOILS, BUT NOT MUCH DIFFERENT FROM NORMAL. SEVERAL LOCATIONS  
HAVE FLOOD PROBABILITIES CLOSE TO NORMAL. MOST STREAMS IN MISSOURI  
HAVE A LIKELIHOOD OF SEEING MINOR FLOODING OVER THE NEXT 90 DAYS. IN  
ILLINOIS, THE ILLINOIS RIVER AND LA MOINE RIVER ARE ALSO EXPECTING  
ABOVE NORMAL CHANCES OF FLOODING THIS SPRING. ON THE KASKASKIA  
RIVER, FLOOD CHANCES ARE CLOSE TO NORMAL AT VANDALIA, BUT THIS MEANS  
MINOR FLOODING IS LIKELY AT THIS LOCATION.  
 
IN THE NEAR TERM, THE CLIMATE PREDICTION CENTER CALLS FOR BELOW  
AVERAGE TEMPERATURES THROUGHOUT THE BI-STATE REGION AND NEAR TO  
BELOW NORMAL PRECIPITATION CHANCES IN THE 6 TO 10 DAY OUTLOOK. BY  
DAYS 8 THROUGH 14, TEMPERATURES SHOULD WARM TO NEAR NORMAL WITH  
PRECIPITATION REMAINING BELOW NORMAL. LOOKING AHEAD TO THE NEXT 3  
MONTHS, THERE ARE EQUAL CHANCES OF TEMPERATURES BEING ABOVE, BELOW,  
OR NEAR NORMAL THROUGHOUT THE ST. LOUIS SERVICE AREA, BUT  
PRECIPITATION IS EXPECTED TO BE ABOVE AVERAGE FROM MARCH THROUGH MAY.  
 
IN TABLE 1 BELOW...THE CURRENT (CS) AND HISTORICAL (HS) OR NORMAL  
PROBABILITIES OF EXCEEDING MINOR...MODERATE...AND MAJOR FLOOD STAGES  
ARE LISTED FOR THE VALID TIME PERIOD.  
 
CS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY  
BASED ON CURRENT CONDITIONS.  
 
HS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY  
BASED ON HISTORICAL OR NORMAL CONDITIONS.  
 
WHEN THE VALUE OF CS IS MORE THAN HS...THE PROBABILITY OF  
EXCEEDING THAT LEVEL IS HIGHER THAN NORMAL. WHEN THE VALUE OF CS IS  
LESS THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS LOWER  
THAN NORMAL.

OF CLIMATOLOGICAL DATA...INCLUDING CURRENT CONDITIONS OF THE  
RIVER...SOIL MOISTURE...SNOW COVER...AND 30 TO 90 DAY LONG-RANGE  
OUTLOOKS OF TEMPERATURE AND PRECIPITATION. BY PROVIDING A RANGE OF  
PROBABILITIES...THE LEVEL OF RISK ASSOCIATED WITH LONG-RANGE PLANNING  
DECISIONS CAN BE DETERMINED. THESE PROBABILISTIC FORECASTS ARE PART
