HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE LA CROSSE WI
424 AM CDT THU APR 24 2014

...RIVERS LIKELY TO RISE INTO THE WEEKEND...

WITH RIVER LEVELS ALREADY ELEVATED DUE TO RECENT RAINFALL AND
PREVIOUS SNOW MELT...ANOTHER RISE BACK UP TO BANKFULL OR FLOOD
STAGE APPEARS POSSIBLE ON SOME AREA RIVERS IF RAINFALL AMOUNTS
REACH THE FORECAST AMOUNTS. THE CURRENT FORECAST IS FOR AROUND AN
INCH TO AN INCH AND A HALF OF TOTAL RAINFALL FROM YESTERDAY INTO
TONIGHT FOR ALMOST ALL OF THE REGION. BASED ON THIS AMOUNT OF
WIDESPREAD RAINFALL...RIVER FORECASTS ARE SHOWING A RISE BACK UP
TOWARD BANKFULL AND FLOOD STAGE...PARTICULARLY ALONG THE KICKAPOO
RIVER THIS WEEKEND. THIS RUNOFF ALSO LEADS TO A SECONDARY RISE
ALONG THE MISSISSIPPI RIVER FOR NEXT WEEK.

ANOTHER CONCERN IS THE SETUP FOR NEXT WEEK AS A SYSTEM STALLS OUT
ACROSS THE CENTRAL PLAINS. THE POTENTIAL IS THERE FOR AN
ELONGATED PERIOD OF RAINFALL FROM SATURDAY NIGHT THROUGH MONDAY.
THERE STILL IS A LOT OF UNCERTAINTY WITH THIS SETUP INTO EARLY
NEXT WEEK...BUT ANOTHER INCH OR TWO OF RAIN IS NOT OUT OF
QUESTION. IF THESE RAINS OCCUR...THE THREAT OF ADDITIONAL RISES
AND MORE FLOODING WOULD CONTINUE WELL INTO NEXT WEEK.

432 AM CDT THU APR 24 2014

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHEAST
IOWA...SOUTHEAST MINNESOTA...AND SOUTHWEST INTO CENTRAL
WISCONSIN.

.DAY ONE...TODAY AND TONIGHT

ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS THE REGION THROUGH MUCH
OF THE DAY BEFORE ENDING FROM WEST TO EAST LATE THIS AFTERNOON
INTO THIS EVENING. VERY SMALL HAIL...BRIEF DOWNPOURS AND LIGHTNING
ARE THE MAIN HAZARDS WITH ANY THUNDERSTORMS THAT DO DEVELOP.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

RAINFALL FROM TODAY COMBINED WITH RECENT RUN OFF COULD LEAD TO
SOME RIVERS GOING BACK UP TOWARD BANKFULL OR FLOOD STAGE BY THIS
WEEKEND. CURRENT FORECASTS SUGGEST AROUND AN INCH TO AN INCH AND A
HALF OF RAIN FALLING ACROSS THE REGION. MORE RAIN FROM THE LATE
WEEKEND INTO EARLY NEXT WEEK COULD ALSO CAUSE SOME ADDITIONAL
RISES...BUT THERE IS MORE UNCERTAINTY DURING THIS TIME WITH WHERE
THE HEAVIER RAIN COULD END UP FALLING.

THERE IS A SLIGHT CHANCE FOR THUNDERSTORMS SATURDAY NIGHT INTO
SUNDAY NIGHT...MAINLY FOR NORTHEAST IOWA...SOUTHEAST MINNESOTA
AND SOUTHWEST WISCONSIN. IT IS TOO FAR OUT AT THIS TIME TO
DISCERN WHETHER SEVERE WEATHER IS POSSIBLE FROM THESE STORMS.

.SPOTTER INFORMATION STATEMENT...

ANY RAINFALL REPORTS ARE APPRECIATED.

.EMERGENCY MANAGEMENT COORDINATION...

NO WEBINAR IS SCHEDULED.
