The Quad Cities National Weather Service also says for tributaries, the flood risk is near normal to slightly above normal.
Hydrologist, Matthew Wilson, says two weeks ago, the chance of major flooding was 82% at Lock & Dam 15 in the Quad Cities. It's now 67%.
"We're going to get equal chances for normal weather up in the Minnesota, Wisconsin area. So that puts us on a good track for April to hope they have what we want and slightly above freezing days. So we're talking about temperatures maybe in the mid-40s to just about 50 degrees but then falling back below freezing at night. That allows for a nice steady melt up there."
But that doesn't mean we're "out of the woods yet." Wilson says even more snow has fallen in Minnesota and Wisconsin over the last two weeks.
"And that's due primarily to the fact that the last couple weeks have been drier than usual in the local area, which has a reduced somewhat streamflows down here and slightly dried out the soils."
For most locations from Dubuque to Burlington, he says the chance of major flooding is at least 50%.
The "worst case scenario" includes local heavy rainfall during the crest on the Mississippi. That should be in late April or early May.
Wilson says he and his colleagues at the National Weather Weather Service office in Davenport will keep an eye on any developments related to flooding.
