Southern parts of the United States over the weekend were struck by severe storms and multiple tornadoes with forecasts that the extreme weather will persist with hail, heavy rain and strong winds.

"The severe weather early this week over the Central states may be every bit as violent as this past weekend and could bring worse conditions to locations that were skipped over by recent storms," AccuWeather Senior Meteorologist Alex Sosnowski said.

The wave of severe weather began Friday when storms began rolling through Texas, Louisiana, Oklahoma, Kansas and Nebraska. It was due to a low-pressure front that hit the region, replacing warm and moderate temperatures.

In total, there were 67 tornadoes reported between Friday and Sunday.

The latest forecast indicates that there’s still plenty of storm left, with as many as 10 million people in the central plains under a flash flood watch.

According to the National Weather Service, Northern Texas, Oklahoma, and Kansas are expecting more tornadoes to hit through Monday. The Oklahoma City metro area is considered "high risk."

"It looks like there is no end in sight to this very active pattern of severe weather into the end of May," AccuWeather Extreme Meteorologist Reed Timmer said.
