HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
206 PM CDT WED JUN 19 2013

...A WET PATTERN IS EXPECTED ACROSS THE UPPER MISSISSIPPI
RIVER VALLEY THROUGH LATE THIS WEEK AND INTO EARLY NEXT WEEK...

...FLOODING COULD BECOME A PROBLEM ESPECIALLY FOR THIS WEEKEND AND
EARLY NEXT WEEK...

A VERY SLOW MOVING UPPER AIR PATTERN WILL ALLOW FOR SEVERAL ROUNDS
OF SHOWERS AND THUNDERSTORMS LATE THIS WEEK...THIS WEEKEND AND
EVEN INTO EARLY NEXT WEEK. WE WILL SEE BREAKS IN THE ACTIVITY AND
WE WILL SEE SOME SUN. HOWEVER GIVEN THE UNSETTLED ATMOSPHERE THE
SUN WILL LIKELY CAUSE SHOWERS AND THUNDERSTORMS TO REFIRE. THIS
WILL BE THE CYCLIC PATTERN FOR AT LEAST THE NEXT FIVE DAYS.

MOISTURE LEVELS WILL BE ON THE RISE ON FRIDAY AND THE WARM AND
HUMID AIR MASS WILL REMAIN ENTRENCHED ACROSS THE REGION INTO
MONDAY. FOR AREAS THAT SEE THUNDERSTORMS...ESPECIALLY THIS
WEEKEND...RAINFALL RATES OF 1.5 TO 2 INCHES AN HOUR WILL BE
POSSIBLE WITH THE EAVIER RAIN CORES. AREAS THAT RECEIVE THESE
HEAVIER AMOUNTS COULD SEE LOCALIZED FLOODING.

WIDESPREAD RAIN FALL AMOUNTS OF 2 TO 4 INCHES OF RAIN WILL BE POSSIBLE
THROUGH THE END OF THE WEEKEND WITH ISOLATED HIGHER AMOUNTS
POSSIBLE. AREAS THAT AREADY HAVE NEARLY SATURATED SOILS DUE TO
RAIN RECEIVED EARLIER THIS WEEK INCLUDE PARTS OF THE UPPER AND
CENTRAL MINNESOTA RIVER BASIN. HENCE LOCALIZED FLOODING COULD
DEVELOP ESPECIALLY IN THE SMALLER CREEKS AND STREAMS AS WELL AS
RIVERS INCLUDING THE CHIPPEWA RIVER IN MINNESOTA...SHAKOPPE
CREEK...BUFFALO CREEK...EAST FORK OF BEAVER CREEK...REDWOOD
RIVER...COTTONWOOD...LITTLE COTTONWOOD...WATONWAN...BLUE
EARTH...COBB AND LE SUEUR RIVERS.

IF WE SEE SIGNIFICANT RAINS...MAIN STEM RIVER FLOODING ON THE
MINNESOTA AND MISSISSIPPI RIVERS AS WELL AS THE CHIPPEWA RIVER IN
WISCONSIN COULD BE A PROBLEM THIS WEEKEND AND INTO EARLY NEXT
WEEK.
