PROBABILISTIC HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
325 PM CST THU MAR 3 2016

...2016 SPRING FLOOD AND WATER OUTLOOK NUMBER 2...

THIS OUTLOOK IS FOR STREAMS WITHIN THE NATIONAL WEATHER SERVICE
CHICAGO HYDROLOGIC SERVICE AREA...WHICH INCLUDES ILLINOIS RIVER
TRIBUTARIES IN NORTHEAST ILLINOIS AND NORTHWEST INDIANA. IT INCLUDES
THE ILLINOIS RIVER DOWN TO LA SALLE. IT ALSO INCLUDES STREAMS WITHIN
THE ROCK RIVER BASIN IN NORTH CENTRAL ILLINOIS AND THE ROCK RIVER
FROM ROCKTON DOWN TO DIXON ILLINOIS. THIS OUTLOOK IS FOR THE TIME
PERIOD FROM EARLY MARCH THROUGH LATE MAY.

..OUTLOOK BRIEF SUMMARY...
BASED ON CURRENT CONDITIONS...THERE IS A SLIGHTLY GREATER THAN
NORMAL RISK OF FLOODING THIS SPRING WITHIN THE KANKAKEE RIVER
BASIN. ELSEWHERE...THE RISK OF FLOODING THIS SPRING
RANGES FROM NEAR NORMAL TO NORMAL. THE AMOUNT OF RAINFALL OR
ADDITIONAL SNOW AND SUBSEQUENT SNOWMELT IN THE COMING WEEKS WILL
DETERMINE THE SEVERITY OF ANY FUTURE FLOODING.

THIS SPRING OUTLOOK IS BASED ON HYDROLOGIC CONDITIONS INCLUDING THE
CURRENT SOIL MOISTURE...SNOWPACK...AND STREAMFLOW CONDITIONS AT THE
TIME OF ISSUANCE. IT SHOULD BE NOTED THAT HYDROLOGIC CONDITIONS CAN
CHANGE RAPIDLY DURING LATE WINTER AND EARLY SPRING. THESE OUTLOOKS
ARE ISSUED EACH LATE WINTER AND EARLY SPRING IN ADDITION TO THE 7
DAY RIVER FORECASTS THAT ARE ISSUED WHEN RIVER FORECAST LOCATIONS
ARE IN FLOOD OR ARE FORECAST TO RISE ABOVE FLOOD STAGE.

...CURRENT SNOW COVER AND WATER EQUIVALENT...
AS OF MARCH 3...SNOW DEPTHS AVERAGED BETWEEN 1 AND 4 INCHES
WITH THE DEEPER SNOWPACK NEAR THE WISCONSIN STATE LINE. WATER
EQUIVALENT OF THE SNOWPACK WAS GENERALLY LESS THAN 0.5 INCH.

...PAST TEMPERATURE AND PRECIPITATION...
FALL OF 2015 CONCLUDED WITH ABOVE NORMAL TEMPERATURES.
PRECIPITATION THIS PAST FALL OVER MOST OF NORTHEAST AND NORTH
CENTRAL ILLINOIS WAS ABOVE NORMAL. IN EARLY FALL...THERE WAS AN
EXTENDED DRY PERIOD FROM MID SEPTEMBER TO THE END OF OCTOBER.
NOVEMBER EXPERIENCED WELL ABOVE NORMAL PRECIPITATION. SOME
LOCATIONS EXPERIENCED 200 PERCENT OF NORMAL IN NOVEMBER. DUE TO THE
DRY START OF FALL 2015...SOME LOCATIONS IN CENTRAL ILLINOIS WERE
CONSIDERED ABNORMALLY DRY BY THE END OF OCTOBER. HOWEVER...SOIL
MOISTURE WAS QUICKLY REPLENISHED AFTER HEAVY PRECIPITATION DURING
THE MONTH OF NOVEMBER. WINTER PRECIPITATION WAS HEAVY IN LATE
DECEMBER WHEN HEAVY RAIN FELL ACROSS THE AREA AND RESULTED IN
WIDESPREAD FLOODING. THE STATEWIDE AVERAGE PRECIPITATION FOR
DECEMBER WAS 6.70 INCHES...WHICH WAS 4.01 INCHES ABOVE AVERAGE.
TEMPERATURE AND PRECIPITATION FOR METEOROLOGICAL WINTER WHICH
ENDED ON FEBRUARY 29...WERE ABOVE NORMAL. SNOWFALL...HOWEVER...
WAS WELL BELOW NORMAL.

...SOIL MOISTURE AND FROST DEPTH...
ALTHOUGH SOIL MOISTURE WAS BELOW NORMAL AT THE START OF FALL...HEAVY
RAINFALL IN DECEMBER BEFORE THE GROUND FROZE...QUICKLY RECHARGED SOIL
MOISTURE. SNOWFALL OVER THE KANKAKEE RIVER BASIN IN EAST CENTRAL
ILLINOIS AND NORTHWEST INDIANA INCREASED THE SOIL MOISTURE IN RECENT
WEEKS. ELSEWHERE...SOIL MOISTURE IS CURRENTLY ESTIMATED TO RANGE FROM
NEAR NORMAL TO ABOVE NORMAL. FROST DEPTHS RANGED FROM 2 TO 6 INCHES
WITHIN AREAS THAT BORDER THE WISCONSIN STATE LINE. ELSEWHERE...FROST
DEPTHS RANGED FROM ZERO TO AROUND 1 INCH.

...RIVER CONDITIONS...
STREAMFLOW WAS ABOVE NORMAL ON PORTIONS OF THE IROQUOIS AND KANKAKEE
RIVERS WHERE WATER LEVELS HAD EXPERIENCED RISES DUE TO RECENT
SNOWMELT. ELSEWHERE...STREAMFLOW WAS NEAR NORMAL.

...WEATHER OUTLOOKS...
THE 6 TO 10 DAY OUTLOOK VALID FROM MARCH 8 TO MARCH 12 INDICATES
GREATER THAN NORMAL CHANCES FOR ABOVE NORMAL TEMPERATURES AND ABOVE
NORMAL PRECIPITATION. THE LATEST OUTLOOK FOR THE MONTH OF MARCH
INDICATES GREATER THAN NORMAL CHANCES FOR ABOVE NORMAL TEMPERATURES
AND EQUAL CHANCES OF ABOVE OR BELOW NORMAL PRECIPITATION.

...FLOOD POTENTIAL SUMMARY...
BASED ON CURRENT CONDITIONS...THERE IS A SLIGHTLY GREATER THAN
NORMAL RISK OF FLOODING THIS SPRING WITHIN THE KANKAKEE RIVER
BASIN. ELSEWHERE...THE RISK OF FLOODING THIS SPRING RANGES FROM
NEAR NORMAL TO NORMAL.

THE AMOUNT OF RAINFALL OR ADDITIONAL SNOW AND SUBSEQUENT SNOWMELT
IN THE COMING WEEKS WILL DETERMINE THE SEVERITY OF ANY FUTURE
FLOODING.

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.
