Current conditions as of March 25:
A lot of ice was lost on the Mississippi this past week in many
areas...however...Lake Pepin continues to have a very significant
ice cover which is a foot or more thicker than it ever was last
winter. Further south...most of the significant ice that was in
the region of Dam 8 down to Dam 12 on the Mississippi has broken up
and disappeared. There is no ice on the Illinois River. See the
table above for details from the available March 25 reports.
Outlook for next 7 days:
Temperatures are forecast to dip down about 10 degrees below
normal by this Thursday and Friday..but then return to normal by
Sunday. Overnight lows will drop below freezing into the 20s
as far south as Davenport Iowa for those few days..but daytime
highs should reach into the upper 30s..40s and 50s across most
of the region south of Minneapolis Minnesota. Based on these
temperature forecasts...we do not expect any new ice development
of any consequence. Instead...there should be continued gradual
deterioration and diminishment of the remaining ice on the
Mississippi at Lake Pepin and other backwater areas this week.
The National Weather Service Long Range Temperature Outlook for
April (issued March 20) indicates an expectation that
temperatures should run near to slightly above normal over the
Upper Midwest when the entire month is taken into account.
The next Ice Statement will be released on Tuesday..Apr 1 2008.
