Ingredients are coming together for a potentially active day of severe weather in eastern Nebraska and western Iowa.The biggest key in the forecast is the warm front that is lifting north out of central Kansas.Current thinking puts this front over the KETV viewing area Thursday afternoon, then stalls out through the evening and overnight.Wind shear -- changes in wind direction with height -- is greatest near the warm front, and that provides a better environment for rotating thunderstorms, as well as isolated tornadoes.There is some question as to how far north the front will travel. It could be anywhere between the Kansas border and the Interstate 80 corridor, including Lincoln and Omaha.Regardless of where it is, the greatest tornado potential will be along the front.As far as timing goes, the front crosses the Kansas border in the early afternoon. Storms could develop as early as noon to 1 p.m. south of Lincoln. Later in the afternoon, storm chances increase in Lincoln and Omaha.The best chances for severe storms would be between 3 p.m. and 8 p.m. While the greatest tornado threat is along the front, any storm today has the potential to produce large hail and damaging winds.When the front stalls, more storms are expected overnight and early Friday morning. Those storms could also be strong or severe, but with more of a wind and hail threat. With repeated rounds of storms, flash flooding will also be possible through Friday morning.*****RESOURCES:-Download the KETV Weather Now app-Watch live streaming radar-Send us your photos
