Severe Potential Tuesday Evening

Severe Thunderstorms are possible Tuesday evening and overnight across the area. The greatest threat for tornadoes has shifted into south central Nebraska and parts of southeast Nebraska along a warm front that has lifted north during the early evening.  The south central Nebraska storms will eventually become a complex of storms and race to the northeast along the warm front.  Areas from Lincoln to Omaha can expect storms from mid to late evening when this occurs.  Outside of the tornado threat, any storms that race to the northeast could produce damaging winds and some large hail.

Farther to the north, warm temperatures in the mid levels of the atmosphere have held off any sustained thunderstorm development so far. However there is still a chance for strong thunderstorms during the evening. The best shot for severe storms in northeast Nebraska and west central Iowa appears to come from a line of storms moving out of western Nebraska and sweeping east overnight, most likely after midnight. Damaging winds will be the primary threat with these storms.

And with any of the thunderstorms, plenty of moisture is available for precipitation. So bouts of heavy rain could also occur. Thus a Flash Flood Watch is posted for a large part of the area.
