This Hazardous Weather Outlook is for portions of southwest
Iowa...west central Iowa...east central Nebraska...northeast
Nebraska and southeast Nebraska.

.DAY ONE...Today and Tonight

Minor to locally moderate flooding will continue along the 
Missouri River above Lewis and Clark Lake, and from near Decatur 
southward past Rulo. 

An isolated thunderstorm or two are possible through tonight.
Severe weather is not expected.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

River levels along the Missouri River will continue to rise south
of Omaha. Minor flooding is expected near Omaha, with moderate 
flooding occurring south of Nebraska City. Additional rainfall 
Saturday night may impact river levels at Brownsville and Rulo,
and future river forecasts may need to be adjusted to account for
this. Anyone with travel plans along Interstate 29 or interests 
near the Missouri River should monitor the forecast closely.

Heavy rain is possible in southeastern Nebraska and southern Iowa
between 10 PM Saturday and 6 AM Sunday. Rainfall totals over an
inch are possible, with a slight risk of up to 4 inches of 
rain. There will also be a slight risk for hail or damaging 
winds. Forecaster confidence in higher end rainfall totals is 
moderate, but these totals may occur further south in Kansas 
and Missouri.

A couple rounds of thunderstorm activity are possible between next
Tuesday and Thursday. However confidence is to low to pinpoint 
them at this time.


Spotter activation will not be needed through tonight.
