Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1254 PM CDT Wed Aug 16 2017


Mostly lighter rain fell in the NCRFC area over the past 24 hours.
Rainfall was largely confined to western Minnesota and Iowa, with
totals ranging from 0.05 to 0.2 inches in most of the affected
area. Greater amounts of precipitation were observed in
southeastern Minnesota, and western Iowa. In SE MN, totals
approached 1.4 inches while western Iowa caught the eastern edge
of the storm system in Nebraska and saw totals nearing four
inches.  Finally, eastern lower Michigan saw another round of
moderate rainfall with totals approaching half an inch.

In the forecast...storms are expected over central Minnesota with
the capacity to produce 1.5-2.5 inches of rain over much of the
state.  Moderate rainfall is expected over most of Iowa, Wisconsin
and Illinois with totals expected to approach 0.5 to 1 inch. This
system will move north east, bringing similar amounts of rain to
Michigan in day 2 of the forecast.

...Hydrologic Conditions...
No flooding is currently occurring.  The most likely forecast
rainfall scenarios would only produce in-bank rises.  Lower
probability higher rainfall totals would produce bankfull flows
with some minor flooding across central Minnesota into western
Wisconsin.  However, recent rainfall history to the west of the
NCRFC has favored efficient rainfall processes.  Locally heavier
rainfall amounts...possibly in the 3 to 6 inch range...would cause
flash flooding and possibly cause local moderate flooding.  Most
likely areas affected would be across southern Minnesota into
western Wisconsin.
