A cold front moved through Iowa during the afternoon of the 11th into the morning of the 12th.  The front stalled over southeast Iowa in response to a strong upper level ridge of high pressure building in the central and southeast U.S. as a result of Hurricane Ike in the Gulf of Mexico.  A strong push of moist air took place as residual moisture from the remnants of Eastern Pacific tropical system Lowell lifted northeast into the central U.S.  Precipitable water values rose into the two to two and one half inch range, with surface dewpoints in the upper 60s to low 70s.  A band of tropical rain developed in the vicinity of the stalled cold front. Copious amounts of rain fell over the southeast third of Iowa.  There were two main bands of heavy rain.  One extended from Lamoni, northeast toward Montezuma.  In this area, rainfall of 3 to 4 inches was common, resulting in some flash flooding in Clarke and Lucas Counties.  Water overtopped U.S. Highways 34, 65, and 69.  The second band of heavy rain brushed the far southeast part of the CWA with rainfall of 4 to 7 inches reported over the southeast half of Davis County.  The heavy rainfall caused flash flooding in the far southeast part of the county in the Pulaski area.  Once the rain tapered off, general flooding continued in Lucas County where U.S. Highway 65 remained closed through the day by high water from White Breast Creek.  The heavy rainfall in southeast Davis County caused one local creek to expand to one quarter of a mile in width.  The observer reported the water is higher than I've seen since 1947.
