In the past 24 hours a cold system of wintery mix moved across
most of the NCRFC area. The only areas that did not have any
precipitation were eastern Lower Michigan... northwest North
Dakota... and far northern Minnesota. Much of South Dakota...
north west Iowa... and Minnesota had snowfall accumulations...
while most of the rest remaining NCRFC area had warm enough
temperatures to avoid snow accumulations. Water equavalent amounts
were variable across the region.. but most of the area of
precipitation received between two and four tenths of an inch. The
stretch between the tri-state borders of SD/IA/MN and SD/ND/MN had
higher amounts around four to eight tenths of an inch. The
western edge of Lake Michigan had higher amounts as well. This
higher pocket extended weast from the lake shore 60-80 miles and
also had around four to eight tenths of an inch water equavalents.
Precipitation accumulations will taper back in the next 24 hours as
this system pushes northeast. Eastern Southe Dakota... western
Minnesota... and northern Iowa may see some risidual accumulations
of around a tenth of an inch on the back side of this system.
Highest accumulations will occurr over the Arrowhead region of
Minnesota and the Upper Peninsula of Michigan. This region will
see around two to four tenths of an inch water equavalent
Minor flooding is forecast at many locations in
Southeastern Iowa: Along the lower reaches of the Des Moines..
Skunk.. Iowa and Wapsipinicon Rivers.
Northern Illinois: Portions of the Rock and Illinois River
In addition to these tributaries.. several Mississippi River
locations along the Missouri/Illinois border and along the
Illinois River are experiencing minor flooding.
Normally we would have issued our long range probabilistic
products last week. However.. after consulting with our local
weather offices.. we decided to postpone the release until the
last storm system left our service area. The long range products
will be issued this week instead.
