Some ice has formed in the pools of Dams 1 through 13 during the 
last week or so. Amounts generally vary from 1 to 3 inches as of
today..Tuesday December 3. Further south water temperatures have
dropped into the mid 30s all the way down to Dam 24 in the

See the comments above for details.

Outlook for next 7 days:
A very strong Arctic blast of extremely cold air is forecast to
move into the Upper Midwest over the next few days. Temperatures
are expected to plummet down to near 10 below in Minneapolis by 
this Thursday or Friday night. And by this Saturday...temperatures 
as far south as St Louis will have dropped into the teens and 20s...
likely staying there well into next week. Based on these factors...
significant ice development of 4 inches or more is anticipated to
occur over the next 7 days on the Mississippi possibly as far 
south as about Dam 22...with lighter amounts further south...plus
on typical ice-prone locations of the Illinois River such as 
Peoria Lake and the upper portions above Lockport.

The next Ice Statement will be released on Tuesday..Dec 10 2013.
