This thread will be the LONG term discussion result of all of these heavy rain systems and snowpack melt..each system individually will have its own thread but this thread will the accumulative result of those.

Also the big main stream river flooding threads will be discussed here (Mississippi, Illinois, Wabash and Ohio) since they crest well after each system has passed.

This thread will focus on WI, IA, IL, IN, OH, KY and MO...as well any flooding of the Mississippi downstream to the Gulf coast as the result of heavy rain in these areas.

Here are same articles and maps to get started

February wettest on record in Illinois

March 7, 2008The Associated Press


CHAMPAIGN -- The state climatologist says last month was the wettest February in Illinois since records started being kept in 1895. The 4.48 inches of precipitation Illinois received in February was 2.49 inches above average, according to Jim Angel of the Illinois State Water Survey in Champaign. February was colder than normal, too. The statewide average temperature for the month was 25.2 degrees , 5.2 degrees below average. Angel says wetter than average conditions in December and January -- plus February totals -- have made this the third wettest winter on record. The state received 11.32 inches of precipitation this winter.

1997 i think

keep in mind that these crests do not include any future precip after 24 hours

[joshMO]

The last few runs of the GFS give the flood stricken areas more than 7" of rain in the next two weeks!

on the mississippi, 2002 I believe,

the ohio river forecasts, 1997 last time for major flooding, although I'd have to confirm that with beau, and on the wabash in mt carmel, actually the last flood like that was in Jan of last year, but the record is from jan 2005 of 33.95'

[BeauDodson]

What makes this flood even more impressive, is the fact that in 1993 the flood took weeks to develop. This event happened in two days. Some of the areas that were hit hard in 1993 are seeing crests that are higher than that event.

Current Major Flooding in U.S. a Sign of Things to Come
NOAA Urges Communities to Prepare During Flood Safety Awareness Week

March 20, 2008

Turn Around, don't Drown poster

Major floods striking America’s heartland this week offer a preview of the spring seasonal outlook, according to NOAA’s National Weather Service. Several factors will contribute to above-average flood conditions, including record rainfall in some states and snow packs, which are melting and causing rivers and streams to crest over their banks. This week, more than 250 communities in a dozen states are experiencing flood conditions.

The science supporting NOAA’s short-term forecasts allows for a high level of certainty. National Weather Service forecasters highlighted potential for the current major flood event a week in advance and began working with emergency managers to prepare local communities for the impending danger.
