气象预报员表示，在强度短暂减弱后，强烈龙卷风、大冰雹、破坏性大风和山洪暴发的威胁将于周五晚间至周末初再次袭击美国中部地区。
周五晚间，得克萨斯州至威斯康星州共有超过5100万人面临恶劣天气威胁，大部分风暴将在午后和晚间时段出现。此次预报发布之际，各社区仍在清理本周早些时候龙卷风过后的废墟。
美国国家气象局表示， overnight 从得克萨斯州到东北部地区将出现强雷暴，周五美国中部和中西部地区也将遭遇此类天气。

新一轮威胁来袭之际，全美各地的社区都在处理龙卷风带来的后续影响。
哥伦比亚广播公司资深全国气象通讯员罗伯·马西亚诺周五报道称，纽约州西部布法罗以南的一个社区在周四完成灾后清理，前一天一场小型龙卷风造成了严重破坏。
密苏里州克林顿市周三晚间遭遇两场龙卷风，树木砸中了安德鲁·唐纳森的屋顶和车库。
“我从未见过这样的场面，”他说道，并补充道，“我再也不想看到这种事了。”
密歇根州创纪录洪水
与此同时，密歇根州正遭遇创纪录的洪水，州长格蕾琴·惠特默已为33个县宣布进入紧急状态。
“我们目前处于危机模式，”她周四说道，“恢复模式还需要开展更多工作。”
马西亚诺报道称，该州西部的马斯基根河水位已创下历史新高。在密歇根州北部，水位已濒临漫过切博伊根地区一座水坝的危险边缘，格蕾琴表示官员们“正在密切监测各地的高水位情况”。
威斯康星州密尔沃基市在周三晚间的暴雨袭击后，周四道路仍处于积水状态。官员称，该州一名41岁男子疑似遭雷击身亡。

Maps show more severe storms forecast for central U.S. after days of tornadoes, flooding
April 17, 2026 / 8:48 AM EDT / CBS News
The threat of strong tornadoes, large hail, damaging winds and flash flooding is returning to the central U.S. Friday evening into the start of the weekend — after a brief break in intensity, forecasters say.
More than 51 million people are under the threat of severe weather Friday evening from Texas to Wisconsin, and most of the storms will occur in the afternoon and evening hours. The forecast comes as communities are still cleaning up from tornadoes that struck earlier in the week.
Severe thunderstorms are forecast from Texas to the Northeast overnight, and for the central US. and Midwest on Friday, says the National Weather Service.
Maps show severe weather, tornado forecast for Friday
The Upper Mississippi Valley — spanning parts of Illinois, Iowa, Minnesota, Wisconsin — will have “the best chance for strong tornadoes,” while parts of the central U.S. and Midwest will have “the best chance for very large hail,” the weather service said Friday.
This map shows the potential for severe weather Friday spanning from the U.S.-Mexico border up to Canada, touching states from Texas to Michigan:

The threat of tornadoes is seen for parts of multiple states in this map for Friday:

Damaging winds reaching up to 70 mph are also in the forecast for parts of some states in the same region, from Texas up to Green Bay.

Saturday severe storm forecast
The severe storm threat will continue for some states on Saturday, covering cities including Cincinnati, Cleveland, Pittsburgh and Buffalo.
A cold front delivering the storms is moving east, with cold air coming behind it. That will bring temperatures in the East closer to normal for this time of year next week, according to CBS News and Stations meteorologist Nikki Nolan.

Still cleaning up from tornadoes
The new threats come as communities across the nation are dealing with the aftermath of tornadoes.
In western New York, one community south of Buffalo was picking up the pieces Thursday after a small tornado caused tremendous damage the day before, CBS News senior national weather correspondent Rob Marciano reported Friday.
In Clinton, Missouri, two twisters struck Wednesday night, sending trees crashing onto Andrew Donaldson’s roof and garage.
“I’ve never seen anything like that,” he said, adding, “I don’t ever want to see it again.”
Record flooding in Michigan
Meanwhile, Michigan is dealing with record flooding, and Gov. Gretchen Whitmer has declared a state of emergency for 33 counties.
“We are in crisis mode now,” she said Thursday. “Recovery mode will take additional work.”
The Muskegon River in the western part of the state has reached new record highs. In northern Michigan, water is dangerously close to breaching a dam in Cheboygan, and Gretchen said officials are “monitoring high water levels everywhere,” Marciano reported.
In Milwaukee, Wisconsin, roads were still flooded Thursday after a torrential rainstorm slammed the area Wednesday night. A 41-year-old man was killed by a suspected lightning strike in the state, officials said.
