Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1039 AM CDT Thu May 24 2018

Thunderstorms affeected portions of Iowa, Minnesota, Wisconsin, and
North Dakota over the last 24 hours. Some of the storms produced
heavy rainfall, especially along the MN/WI border area just south of
Duluth, where some reports in the 3-4 inch range were seen. But these
heavy amounts were localized enough that the main river systems were
not seeing too large of a rise.

For the next few days, the same general weather pattern will prevail,
with scattered thunderstorm activity from IA, WI and Michigan, and
points westward.  At this point it appears the activity will be
patchy enough so as to not cause too much concern for any widespread
flooding concerns.

Overall trends continue to be downward across the NCRFC region, and
we are now down to almost 50 active forecast locations.

River forecasts routinely incorporate 24 hours of QPF from
April 1 to September 30 and 48 hours from October 1 to March 31.
