HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE NORTHERN INDIANA
653 PM EDT TUE APR 16 2013

...FLOOD THREAT EXISTS LATER THIS WEEK...

A WARM FRONT WILL PUSH NORTH ACROSS THE AREA WEDNESDAY NIGHT INTO
THURSDAY. THEN A LOW PRESSURE SYSTEM WILL EJECT NORTHEASTWARD
FROM THE SOUTHERN PLAINS TO THE WESTERN GREAT LAKES THURSDAY
NIGHT INTO FRIDAY WITH A COLD FRONT SWEEPING THROUGH THE REGION.
SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS WILL BE ASSOCIATED
WITH THESE SYSTEMS FOR THE NEXT SEVERAL DAYS. THE BEST TIME FRAME
FOR THE HEAVIEST RAINFALL APPEARS THURSDAY AFTERNOON THROUGH LATE
THURSDAY NIGHT.

RAINFALL TOTALS FROM WEDNESDAY THROUGH FRIDAY...ALONG AND
NORTHWEST OF A LOGANSPORT TO WARSAW TO COLDWATER LINE...ARE
ANTICIPATED TO BE IN THE 2 TO 4 INCH RANGE...WITH LOCALLY HIGHER
AMOUNTS POSSIBLE. LESSER AMOUNTS ARE CURRENTLY FORECAST TO THE
SOUTHEAST...GENERALLY IN THE 1 TO 3 INCH RANGE.

SEVERAL FACTORS ARE PRESENT THAT WILL MOST LIKELY EXACERBATE
FLOODING LATER THIS WEEK THROUGHOUT THE ENTIRE KANKAKEE...SAINT
JOSEPH MICHIGAN...WABASH AND MAUMEE RIVER BASINS. CURRENT
STREAMFLOW IN SMALLER TRIBUTARIES...AS WELL AS THE LARGER STEM
RIVERS...WILL REMAIN ELEVATED. INITIAL GROUND MOISTURE LEVELS ARE
VERY MOIST. THE LIGHTER RAINFALL THROUGH THURSDAY MORNING WILL
LEAD TO EXTREMELY SATURATED SOILS. THEREAFTER...POTENTIAL EXTREME
RAINFALL RATES ATOP NEARLY IMPERVIOUS...WET GROUND WILL CAUSE
EXCESS RUNOFF.

SHOULD THESE EXTREME RAINFALL AMOUNTS BE REALIZED...WIDESPREAD
AND POTENTIALLY SIGNIFICANT FLOODING OF STREAMS...CREEKS AND LOW
LYING AREAS WOULD RESULT. LARGER MAIN STEM RIVER LEVELS WOULD
THEN LIKELY RISE RAPIDLY EARLY THIS WEEKEND...WITH THE
POSSIBILITY FOR MODERATE RIVER FLOOD LEVELS CONTINUING INTO EARLY
NEXT WEEK.

PEOPLE LIVING IN LOW LYING AREAS OR NEAR STREAM AND RIVERS SHOULD
CHECK FOR THE LATEST FORECASTS AND STATEMENTS FROM THE NATIONAL
WEATHER SERVICE CONCERNING THE HEIGHTENED POTENTIAL FOR FLOODING.
IF YOU LIVE IN A FLOOD PRONE AREA...BEGIN TO GIVE CONSIDERATION
NOW FOR THE POSSIBILITY FOR NEEDED ACTION LATER.
