Today through Friday...

Gulf moisture and the remnants of Hurricane Polo brought significant rainfall and subsequent flooding to eastern Nebraska and western Iowa last night. A swath of 3"-5" fell along I-80 from Lincoln to Omaha, with pockets of 6"-8". Lincoln's official weather station reached 6.15", breaking it's all-time single- day rainfall record of 5.45" set on Aug. 29th of 1910. Flooding covered roads, submerged vehicles, and even triggered a mudslide near Crescent, IA. Ongoing flooding of rivers and streams, is expected to continue downstream into the Missouri River in southeast Nebraska.

Lingering spotty showers are expected to clear out this afternoon as a surface high begins to build into the region behind the departing low. Temperatures will stay in the mid to upper 60s with decreasing humidity. Overnight, lows will fall into the mid 40s, before rising back into the 60s Friday with mostly sunny skies.

Saturday and Beyond...

High pressure will begin to build over the Four Corners region this weekend, with northwesterly upper level flow bringing cool dry air to the Central Plains. Highs will remain in the mid 60s to low 70s Saturday and Sunday.

A trough will dip into the northeastern CONUS Monday, taking temperatures down a few degrees, into the mid 60s. The over the intermountain west will shift eastward on Tuesday, bringing highs back into the 70s for Tuesday through the end of the work week. While we can't completely rule out a weak disturbance kicking up a couple of showers around the middle of the week, overall moisture finally looks to be lacking.
