Thunderstorms were again strengthening across the Plains from Texas to the Dakotas Tuesday afternoon. Severe storms could even reach as far east as Ohio and western Pennsylvania.
Nearly 50 million people across the nation will have some risk for severe thunderstorms, including those in major cities like Chicago, Ill.; Indianapolis, Ind.; Detroit, Mich.; Kansas City, Mo.; St. Louis, Mo.; Cleveland, Ohio and Pittsburgh, Pa.
Tornadoes and large hail impacted parts of Kansas, Nebraska and Oklahoma during the early evening hours. The threat of more severe weather will continue into the late night hours Tuesday.
Winds gusted to 66 mph northwest of Amarillo, Texas and hail as large as golf balls was also reported.
Hail as large as baseballs in western Nebraska, western Kansas and the Oklahoma and Texas panhandles was reported.
This kind of hail is capable of causing serious injury to anyone caught outside. It can also kill exposed livestock, damage or destroy crops and smash windshields.
Elsewhere, hail larger than quarters is possible from Missouri into Illinois and eastward to perhaps Pittsburgh and Erie in Pennsylvania.
Hail of this size is still capable of damaging or denting vehicles and causing injury to people or animals that are exposed.
Winds gusts greater than 60 mph are possible in the isolated storms throughout the threat region, and this kind of wind could easily topple trees, power poles and lift any unsecured objects.
These thunderstorms will also impact some of the same areas that were affected in recent days, and flash flooding from heavy rainfall is a concern, especially across parts of Nebraska, Iowa and Illinois.
If you will be out and about into the evening, keep an eye to the sky, keep an eye on radars on your smart phone and pay attention to weather bulletins.
Once thunderstorms develop, they will strengthen quickly, and severe weather could follow soon after.
Be sure to understand the difference between a watch and a warning. A watch means that an area is being monitored for dangerous weather. A warning means that dangerous weather is imminent.
Keep in mind that lightning is one of Mother Nature's most dangerous killers. If you can hear thunder, you are close enough to the storm to be struck by lightning, even if the sun is still shining.
