...A STORMY AND WET WEATHER PATTERN IS EXPECTED ACROSS THE
NORTHLAND LATE THIS WEEK AND EARLY NEXT WEEK...POTENTIALLY
RESULTING IN HEAVY RAINFALL AND FLOODING...
NORTHEAST MINNESOTA AND NORTHWEST WISCONSIN WILL BE IN A PROLONGED
AND POTENTIALLY VERY WET WEATHER PATTERN LATE THURSDAY AND
THROUGH EARLY NEXT WEEK. A WARM AND HUMID AIRMASS WILL MOVE INTO
PARTS OF THE UPPER MIDWEST THROUGH EARLY NEXT WEEK...AND WILL
PROVIDE THE FUEL FOR SEVERAL BOUTS OF SHOWERS AND THUNDERSTORMS.
EACH ROUND COULD BRING SEVERE WEATHER...INCLUDING HEAVY RAIN AND
LOCALIZED FLOODING.
HOWEVER...EACH SUBSEQUENT ROUND OF STORMS COULD RESULT IN
SIGNIFICANTLY REDUCING THE ABILITY OF THE SOIL TO EFFICIENTLY
ABSORB ADDITIONAL RAINFALL...AND OVERALL RESULT IN AN INCREASING
SUSCEPTIBILITY TO FLASH FLOODING FOR PARTS OF THE NORTHLAND.
WIDESPREAD RAINFALL AMOUNTS OF AT LEAST 2 TO 4 INCHES ARE POSSIBLE
THROUGH THIS PROLONGED STORMY PERIOD...AND SOME AREAS COULD GET
OVER 4 INCHES OF RAIN.
LOW LYING AREAS...HILLY TERRAIN...CREEKS AND SMALL STREAMS...AND
URBAN AREAS WILL BE THE MOST LIKELY AREAS TO GET AFFECTED BY ANY
FLASH FLOODING. IF ENOUGH RAINS FALL OVER PARTS OF THE
NORTHLAND...THEN THERE COULD BE FLOODING ON SOME MAIN STEM RIVERS.

...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.
