Hydrometeorological Forecast Discussion

...Precipitation...
As one system was exiting Michigan and the great lakes region on
Saturday, another weather disturbance was moving into North Dakota
and northern Minnesota. Amounts in the Great Lakes were generally
a dusting. The second round produced generally light snows as
well, but a narrow band did develop along a line from Fargo to
Duluth, with some 2 to 5 inch reports received from this. Water
equivalent in this snow band was up to a quarter-inch. The cold
air also kept the Lake Effect machine going, with some amounts as
high as 3 to 5 inches in the most favored areas.

This second system will continue east through the Great Lakes
Region today, bringing some light accumlations of snow, on the
order of 1 to 5 inches. But look for that activity to end
overnight, leaving the area precipitation free through much of
Monday.

The next system will bring more significant precipitation to much
of the Upper Midwest from Monday night through Tuesday and into
early Wednesday.

...Hydrologic Conditions...

Rain and snowmelt earlier this week generated river rises
exceeding moderate flood levels at a few locations
in Wisconsin.  The Wisconsin River at Portage is
above moderate flood stage and expected to remain there over
the next couple of days.

Elsewhere, minor flooding is occurring or expected in Iowa,
Wisconsin, Minnesota, and along the Red River of the North.

The mainstem Mississippi River could rise above minor or moderate
flood levels in early March as bankfull and minor flooding on area
tributaries flows into the main channel.
