On Monday morning, the US National Weather Service (NWS) issued a tornado watch for sections of Oklahoma and Texas following a weekend of storms in Nebraska and Texas.

The NWS urged Oklahoma and Texas residents to heed the warnings regarding their immediate areas Monday morning, as an "outbreak of severe thunderstorms," tornadoes and even hail were predicted to ravage the Great Plains states.

Winds were predicted by forecasters to exceed 75 mph.

Significant Tornado Outbreak Likely Today



Long-track, fast-moving, and intense tornadoes will be possible today across parts of Texas & Oklahoma. Large hail and damaging winds also a concern.

The federal agency estimated over 2 million people could be impacted by the storm, which was labeled "high risk," scoring a 5 out of 5 on its scale. NWS added that this was only the second time on record in NWS Storm Prediction Center history that "every category of watch probabilities (torn, wind, hail) are greater than 95%."

Craig Hilts, a stormchaser photographing near Paducah, a small town in northern Texas, spotted a funnel forming.

Twitter user @Honzie101 managed to capture video footage from their tornado sighting west of Paducah.

Texas' Midland County also had a tornado touch down.

Here’s a better one I think if y’all want to use. Focused more on the tornado itself. #westtexas#385#odessa#midland pic.twitter.com/4ZCMjerUwN — Awesome B Man/\_/\🎮 (@AwesomeB_Man) May 20, 2019

Stormchaser Aaron Jayjack was able to capture both the calm before the storm and an actual tornado while on the scene in Mangum, Oklahoma.

One Mangum local caught a glimpse of the storm approaching dangerously close to their home

A local Oklahoma outlet was quick to get pictures of the damage caused by the tornado south of Mangum.

A number of areas also experienced icing and hail. A Wellington, Texas, farmer shared a photo of baseball-sized chunk of hail that fell in his city.

While many may have been able to get to shelters, local and national weather stations stressed to Oklahoma City residents idents that OKC does not have public tornado shelters.

"Traffic congestion from hundreds or thousands of other residents trying to get to public shelters could have tragic consequences," the city's website reads. "Being in a vehicle is one of the most dangerous places to be in a tornado, and risking a drive to a shelter during severe weather could be deadly. Many deaths attributable to tornadoes are attributed to being in a vehicle."

While it is too early to get a count of those injured within the areas, as they remain under watch, initial reports from local Oklahoma outlet Stillwater News Press, citing personnel in Enid, Oklahoma, say a man was struck by lightning and rushed to the hospital for related injuries Monday morning.

Storms will continue throughout the night, and tornadoes are expected to touch down in parts Oklahoma and Texas. Regions of Kansas and Missouri are under watch until at least Tuesday as the storm system travels.
