Forecasterssay the storms - which could also bring large hail and damaging winds -are expected to form Sunday afternoon and that the advised area alsoincludes portions of Kansas, Missouri and Nebraska.
In centralIowa, Sunday and the beginning of the week are "the biggest chance we'vehad for severe weather since 2011," forecasters at the National WeatherService told the Des Moines Register.
MeteorologistKurt Kotenberg said a large low-pressure system is parking itself overthe middle of the country and "really isn't going to move much over thecourse of the next few days. ... It's basically going to keep pulling upthat nice Gulf (of Mexico) moisture that keeps fueling everything."
Overall,Iowa has a roughly 70% chance of severe thunderstorms from late Sundayafternoon through midnight, with more storms likely on Monday andTuesday, Kotenberg said. The weather service's "hazardous weatheroutlook" warns of the potential for "all modes of severe weatherpossible," including golf-ball sized hail and winds in excess of 60 mph.
Kotenbergsaid tornadoes are most likely to the south - in Missouri, Kansas andOklahoma - but within Iowa, Des Moines and points southeast could be atthe greatest risk of seeing a twister in the state.
Thethreat of twisters comes less than a week after tornadoes left sixdead, dozens injured and hundreds of homes destroyed in Texas and justshy of the two-year anniversary of the Joplin, Mo., twister that left160 dead on May 22, 2011.
