HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
400 AM CDT SUN MAY 19 2013

...PERIODS OF SHOWERS AND THUNDERSTORMS BRING FLOODING
POTENTIAL...

A SLOW-MOVING LOW PRESSURE SYSTEM APPROACHING FROM THE PLAINS WILL
BRING ROUNDS OF SHOWERS AND THUNDERSTORMS TO SOUTHERN WISCONSIN
THROUGH MID WEEK.

WHILE THERE ARE STILL SOME DIFFERENCES AMONG THE MODELS IN THE
EXACT DETAILS IT APPEARS THAT A SURFACE FRONT EXTENDING EAST FROM
THE APPROACHING LOW WILL BECOME NEARLY STATIONARY ACROSS THE
STATE... AND WILL BE THE FOCUS FOR THE DEVELOPMENT OF REPEATED
ROUNDS OF SHOWERS AND THUNDERSTORMS...CAPABLE OF PRODUCING HEAVY
RAINFALL.

RAIN TOTALS COULD BE MUCH MORE THAN THE AREAL AVERAGE...ESPECIALLY
AT LOCATIONS THAT SEE STORMS WITH HEAVY RAINS REPEATEDLY MOVING
THROUGH.

AREA RIVERS THAT HAVE JUST RECENTLY FALLEN TO...OR BELOW BANKFULL
MAY RISE BACK UP INTO FLOOD. QUICK-RESPONDING RIVERS AND STREAMS
MAY QUICKLY FLOOD IF AFFECTED BY SEVERAL ROUNDS OF HEAVY RAIN IN
A SHORT PERIOD OF TIME. THE HEAVY RAINS COULD CAUSE PONDING OF
WATER ON AREA ROADS.

KEEP UP WITH THE LATEST FORECASTS AND STATEMENTS FOR FURTHER
INFORMATION ON THE FLOODING POTENTIAL.
