Hydrometeorological Forecast Discussion

...Precipitation...

In the last 24 hours, convective storms skirted our southern
boundary, dropping up to about a quarter inch of rain in the
Meramec River basin.  A small wave of rain and snow moved into
central Iowa dropping tenth to over quarter inch total water near
Des Moines.  Very light lake effect snow fell in isolated parts of
the Upper Peninsula and northern lower Michigan.

In the next 24 hours, very light precip may fall on our western
boundary and around Lake Superior again.  The real news is the
pattern shift coming at the end of the week, which will allow a
more organized system to break into our area late Thursday,
through Friday and into the weekend.  Widespread totals of one to
two inches are expected over the southern 3/4ths of the NCRFC
area over the next five days - primarily falling Friday and
Saturday.

...Hydrologic Conditions...

The northern portion of the NCRFC Service Area including northern
North Dakota and northern Minnesota still have a significant snow
cover.

High temperatures in the northern Red River of the North Basin
were above freezing early this week.  This warmup has initiated
runoff in the Two Rivers Basin in northwestern Minnesota where
minor flooding occurred.

Air temperatures in North Dakota and northern Minnesota are
expected to remain well below freezing today before a warming
trend settles in which could initiate snowmelt flooding at other
locations.  It is important to note that these temperature
forecasts can be quite volatile and uncertain so far in the
future.

Long Range Outlook products are being issued today for the Red
River of the North Basin to support flood preparations in the
northern basin.  Products will be issued Friday morning elsewhere
in the NCRFC Service Area.

For additional and more in-depth information concerning river
forecasts, precipitation and all hydrometeorological information
