HYDROMETEOROLOGICAL FORECAST DISCUSSION
NWS NORTH CENTRAL RIVER FORECAST CENTER TWIN CITIES/CHANHASSEN MN
1222 PM CDT WED AUG 20 2014

...PRECIPITATION...

OVER THE PAST 24 HOURS RAIN FELL IN MICHIGAN PLUS PARTS OF
SEVERAL OTHER STATES IN THE UPPER MIDWEST. THE HEAVIEST AMOUNTS
RECORDED WERE IN SOUTHWEST LOWER MICHIGAN WHERE ABOUT 2 TO 2.5
INCHES FELL NEAR GRAND RAPIDS. MOST OTHER AMOUNTS WERE AROUND
AN INCH OR LESS.

ALREADY THIS MORNING NEW AREAS OF RAIN ARE MOVING IN FROM THE
WEST ON MOISTURE-LADEN SOUTHWEST FLOW...AFFECTING AREAS FROM
NORTH DAKOTA ON DOWN TO IOWA AND CENTRAL ILLINOIS. OVER THE
NEXT 24 HOURS...THE AXIS FOR THE MORE SIGNIFICANT AMOUNTS OF
RAIN IS EXPECTED TO RUN SOUTHEASTWARD FROM JUST WEST OF
BISMARCK NORTH DAKOTA OVER TO SOUTHWESTERN MINNESOTA AND
CONTINUING FROM THERE TOWARDS INDIANAPOLIS INDIANA. AMOUNTS
OF 1 TO 1.5 INCHES MAY BE COMMON ALONG THIS LINE...WITH
CONVECTIVELY HEAVIER AMOUNTS ALSO A THREAT DUE TO THE INFLUX
OF WARM AND MOIST AIR BEING BROUGHT INTO OUR REGION.

IT LOOKS LIKE WE ARE HEADING INTO A GENERALLY WET FORECAST
PERIOD FOR THE NEXT SEVERAL DAYS...WITH POSSIBLY THE MOST
SIGNIFICANT RAINS HEADING INTO WESTERN PORTIONS OF NORTH DAKOTA
DURING THIS TIME.

...HYDROLOGIC CONDITIONS...

THERE CURRENTLY IS ONLY ONE FORECAST POINT IN THE NCRFC ABOVE
FLOOD STAGE...WESTHOPE ON THE SOURIS RIVER IN NORTH DAKOTA.

LOCALIZED FLASH FLOODING IS POSSIBLE IN LOCALLY HEAVY STORMS AS
CONVECTIVE STORMS MOVE THROUGH THE AREA IN THE NEXT FEW DAYS.
THERE IS A THREAT OF RIVER FLOODING AS WELL... ESPECIALLY IN
FLASHY BASINS IN ILLINOIS.  NORTH DAKOTA RIVERS COULD ALSO SEE
SIGNIFICANT RISES... BUT THE BULK OF RAIN IS EXPECTED A FEW DAYS
OUT... SO TIMING AND LOCATIONS ARE STILL SUBJECT TO CHANGE.
