New rounds of severe thunderstorms and life-threatening, potentially catastrophic, flooding risks are brewing in the central and eastern United States Tuesday, putting more than 50 million people at risk this week.

Forecasters warned of damaging winds, hailstones bigger than baseballs and flash floods in parts of an area stretching from Texas to upstate New York.

A First Alert Weather Day is in effect Tuesday night through Wednesday in North Texas. We're watching the threat of strong to severe thunderstorms Tuesday evening and night, primarily in our west-northwestern area.

A south breeze remains in place with highs in the mid to upper 80s. Rain is not expected, but it's possible that a light sprinkle could move through.

Weather around Texas will become a bit chaotic for the next several days with lots of humidity and several small disturbances in the jet stream. As a result, the timing and location of storms is challenging.

The National Weather Service is forecasting high temperatures above average, across Southeast Texas both today and tomorrow.
