Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1213 PM CDT Fri Mar 24 2017

...Precipitation...
Widespread showers moved through much of the NCRFC area during the
day Thursday, and continuing into this morning. Thunderstorms were
seen from Iowa into Illinois, Wisconsin, and Michigan. Some of
these produced hail along with locally heavy rainfall. The
fast-moving nature of these storms kept large rainfall amounts
to a minimum for the most part, with amounts less than 0.75
inches. But there were a few isolated reports in the 1.5 to 2 inch
range over southeast Wisconsin. Other bands of rainfall above a
half-inch were seen from far eastern Missouri into southern
Illinois, and also from eastern North Dakota into the Minnesota
arrowhead region. Elsewhere, amounts were generally under a
quarter-inch.

A large and slow-moving closed storm system is expected to meander
slowly east-northeast through the weekend, and will keep the rain
going all the way into early Monday. There will be several
individual pieces of energy rotating about the main low center,
and this will result in several bands of precipitation. These
bands may linger in a spot for a while, but should erode and
reform in other areas as the disturbances move through the region.
Rain amounts over the 3-day period could be as high as 2-3 inches
from parts of IA/MO/IL up into WI and lower Michigan. Lesser
amounts are anticipated from MN into the Dakotas.


...Hydrologic Conditions...
Yesterday`s rainfall, combined with the expected rains described
above, look to push several rivers up over the next several days.
But as of now it appears no flooding will occur with this
activity, with 36 forecasts issued for stages above FIS.

As of now it appears only a handful of locations are expected to
rise above flood stage, and that is a result of snowmelt up in
the Red River valley.

For those with interests along area rivers and creeks, pay
attention to the latest rainfall amounts and river levels, and
watch for any forecast adjustments through the weekend.  Contact
NCRFC with any questions or concerns.
