PROBABILISTIC HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE PADUCAH KY
1000 AM CDT THU MAR 13 2025
..SPRING FLOOD AND WATER RESOURCES OUTLOOK NUMBER 3
THIS OUTLOOK IS FOR THE NWS PADUCAH SERVICE AREA. IT COVERS THE TIME
PERIOD FOR MID-MARCH THROUGH MID-JUNE. IT INCLUDES THE MID-
MISSISSIPPI AND LOWER OHIO RIVERS AND THEIR TRIBUTARIES FOR
SOUTHWEST INDIANA, SOUTHERN ILLINOIS, WEST KENTUCKY AND SOUTHEAST
MISSOURI.
..FLOOD OUTLOOK HIGHLIGHTS
FLOOD POTENTIAL IS NORMAL TO SLIGHTLY ABOVE NORMAL ACROSS THE OHIO
VALLEY AND ITS TRIBUTARIES. FLOOD POTENTIAL IS NORMAL TO BELOW
NORMAL FOR THE OUTLOOK PERIOD FOR THE MISSISSIPPI RIVER VALLEY AND
ITS SMALLER TRIBUTARIES.
FLOODING IN THIS REGION OCCURS MAINLY DUE TO CONDITIONS OF GROUND
MOISTURE, RIVER FLOWS, AND EXPECTED PRECIPITATION. ICE JAMS ARE
RARELY A FACTOR IN FLOODING FOR THIS PART OF THE COUNTRY.
..CURRENT CONDITIONS
VERY HEAVY RAIN FELL ACROSS THE OHIO VALLEY IN MID-FEBRUARY CAUSING
MODERATE TO MAJOR FLOODING ALONG THE GREEN AND OHIO RIVERS. THERE
HAS BEEN LITTLE ADDITIONAL RAINFALL IN THE LAST COUPLE OF WEEKS.
STREAMFLOW IN THESE AREAS IS RUNNING NORMAL TO BELOW NORMAL.
SMALLER RIVERS IN SOUTHEAST MISSOURI ARE RUNNING BELOW NORMAL. THE
OHIO RIVER NEAR THE CONFLUENCE WITH THE MISSISSIPPI RIVER IS RUNNING
AT 50% OF NORMAL WHILE THE MISSISSIPPI RIVER ABOVE CAIRO IS RUNNING
AROUND 86% OF NORMAL.
SOIL MOISTURE IS ABOVE NORMAL ACROSS MOST OF THE REGION. THERE IS NO
FROST DEPTH IN OUR REGION. THERE IS VERY LITTLE SNOW IN THE
MISSISSIPPI OR THE OHIO VALLEYS THAT WOULD CONTRIBUTE SIGNIFICANT
RUNOFF FOR FLOODING.
..WEATHER OUTLOOKS
A STRONG STORM SYSTEM WILL LIFT OUT OF THE PLAINS BRINGING THE
REGION A CHANCE FOR SHOWERS AND THUNDERSTORMS, SOME OF WHICH COULD
BE SEVERE THIS WEEKEND. MOST AREAS COULD SEE UP TO AN INCH OF RAIN
WITH MORE ORGANIZED STORMS PRODUCING UP TO 2 INCHES.
THE 8 TO 14 DAY OUTLOOK FOR MARCH 20 THROUGH 26 CALLS FOR ABOVE
NORMAL TEMPERATURES AND PRECIPITATION. DURING THIS TIME, NORMAL
AVERAGE TEMPERATURES ARE AROUND 50 DEGREES AND RAINFALL DURING THIS
PERIOD IS AROUND 1 INCH.
THE OUTLOOK FOR MARCH CALLS FOR ABOVE NORMAL PRECIPITATION. NORMAL
PRECIPITATION FOR MARCH IS AROUND 4 1/2 TO 5 INCHES. THE OUTLOOK
FOR MARCH THROUGH MAY CALLS FOR ABOVE NORMAL PRECIPITATION.
..PROBABILISTIC OUTLOOKS
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.

THESE LONG-RANGE PROBABILISTIC OUTLOOKS CONTAIN FORECAST VALUES THAT
ARE CALCULATED USING MULTIPLE SEASON SCENARIOS FROM 30 OR MORE YEARS
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
OF THE NATIONAL WEATHER SERVICE'S ADVANCED HYDROLOGIC PREDICTION
SERVICE.
