HYDROLOGIC OUTLOOK...CORRECTED
NATIONAL WEATHER SERVICE ST LOUIS MO
328 PM CST SUN MAR 6 2016

...HEAVY RAINFALL AND FLOODING POSSIBLE THIS WEEK...

A PROLONGED PERIOD OF HEAVY RAINFALL IS POSSIBLE FOR PARTS OF THE
AREA THIS WEEK. THE LATEST WEATHER INFORMATION IS SHOWING TWO
WAVES OF HEAVY RAIN. THE FIRST IS EXPECTED TUESDAY EVENING...AND
THE SECOND WAVE IS EXPECTED WEDNESDAY INTO WEDNESDAY EVENING...
AND COULD EVEN LAST INTO EARLY THURSDAY FOR FAR SOUTHERN PORTIONS
OF THE FORECAST AREA. THE HEAVY RAIN TUESDAY NIGHT CONTINUES TO
LOOK FURTHER NORTHWEST THAN PREVIOUSLY EXPECTED...ACROSS PARTS OF
CENTRAL AND NORTHEAST MISSOURI INTO WEST-CENTRAL ILLINOIS. HOWEVER
THE SECOND AND HEAVIER WAVE IS STILL EXPECTED TO AFFECT THE ST.
LOUIS METRO AREA AND ALL COMMUNITIES ALONG AND SOUTH OF INTERSTATE
44 IN MISSOURI AND INTERSTATE 70 IN ILLINOIS. WIDESPREAD RAINFALL
AMOUNTS OF 2 TO 4 INCHES ARE POSSIBLE TUESDAY THROUGH
THURSDAY...WITH LOCALLY HIGHER AMOUNTS.

CHANCES OF MEASURABLE RAINFALL CONTINUE THROUGH NEXT WEEKEND WITH
ADDITIONAL AMOUNTS OF 1-2 INCHES POSSIBLE. HOWEVER...FORECAST
UNCERTAINTY IS HIGHER FOR LATE THIS WEEK AND FOR NEXT WEEKEND.

THE SOIL MOISTURE ACROSS THE REGION IS ABOVE AVERAGE...WHILE
LOCAL RIVERS AND CREEKS ARE AT NEAR NORMAL LEVELS AND FLOW. THERE
ALSO REMAINS A LACK OF VEGETATION AS WE TRANSITION OUT OF THE
WINTER SEASON...WHICH INCREASES THE POTENTIAL FOR RUNOFF FROM
EXCESSIVE RAINFALL. THESE ANTECEDENT CONDITIONS...COMBINED WITH
THE POTENTIAL OF VERY HIGH RAINFALL TOTALS...COULD LEAD TO RIVER
FLOODING AS WELL AS FLASH FLOODING IN FLOOD PRONE AREAS.

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