Overnight Thunderstorms

Severe and tornadic thunderstorms continue to move across much of the northern and central plains states. Some of these storms may enter the western portions of Iowa within the next few hours, mainly over southwest Iowa where a Severe Thunderstorm Watch is in effect. Currently, a line of thunderstorms is moving into southeast Nebraska and will continue to move northeastward into southwest Iowa likely by 10:30 PM capable of large hail and damaging winds. Other storms over central Nebraska and South Dakota will likely congeal into more of an MCS as the low level jet continues to increase and organize storms and produces additional development. These storms are not as likely to be severe, rather with a continued heavy rain threat over parts of the state which saw heavy rains over the past few days.

Thunderstorms will likely linger across the state tomorrow, with additional development of severe/tornadic thunderstorms possible to move into the state during the evening hours. Additional updates on tomorrow's severe weather threat over the southwestern half of the state is likely tomorrow morning.

The forecast will continue to warm up as well as moisten to allow more chances of thunderstorms later in the week, with another round of severe weather being likely on Thursday across much of the state.
