HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE ST LOUIS MO
445 AM CST SAT MAR 5 2016

...HEAVY RAINFALL AND FLOODING POSSIBLE NEXT WEEK...

A PROLONGED PERIOD OF HEAVY RAINFALL IS POSSIBLE FOR PARTS OF THE
AREA NEXT WEEK. ALTHOUGH THERE IS STILL UNCERTAINTY IN THE LATEST
MODEL DATA...TUESDAY EVENING THROUGH THURSDAY IS THE MOST LIKELY
PERIOD FOR HEAVY RAIN...AND THE SOUTHEAST HALF OF MISSOURI AS
WELL AS THE SOUTHERN HALF OF ILLINOIS ARE THE MOST LIKELY AREAS TO
RECEIVE THE HEAVIEST RAINFALL AMOUNTS. THIS INCLUDES 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 3 TO 6 INCHES ARE POSSIBLE...WITH LOCALLY HIGHER
AMOUNTS.

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.
