A tornado in Round Rock, Texas, damanged several homes and businesses in the area Monday. The tornado was one of multiple that touched down in Texas and Oklahoma, as dangerous storms are forecast for portions of the southern U.S. over the next three days. A tornado watch was issued for parts of central and eastern Texas and southeast Oklahoma into Monday night, meaning weather conditions are ripe for more tornadoes to form. "This is a volatile weather pattern, and we’ve seen these types of storm systems previously produce damaging, dangerous and highly impactful severe weather and flooding," AccuWeather chief meteorologist Jonathan Porter said. Forecasters say the volatility could produce strong and long-lived tornadoes, some of which could strike under the cover of darkness. 📸: @jayjanner, @statesman For more on the weather in the region, click the link in our bio.
