Severe thunderstorms to flood Illinois to Texas through Saturday night

Dangerous thunderstorms and flash flooding will continue to threaten lives and property across the central United States through Saturday night.

Some communities will be rocked by severe weather and flooding for the second consecutive day in a row.

The metro areas of St. Louis; Little Rock, Arkansas; Dallas, Tyler and San Antonio, Texas; and Shreveport, Louisiana, will be blasted by the thunderstorms during the first half of the weekend.

Residents in these cities and their respective suburbs may contend with canceled or altered outdoor plans. Property damage, power outages and flooding may also occur.

Severe Sat 4.29 AM

The thunderstorms threaten to turn particularly violent where rain and clouds exit early in the day and there is a prolonged period of sunshine.

AccuWeather Senior Meteorologist Frank Strait expects the main concentration of severe weather to center over the Arklatex region late on Saturday afternoon into Saturday evening.

Damaging winds up to 70 mph will litter roads and neighborhoods with broken tree limbs and downed power lines. A few tornadoes could also touch down, threatening some communities with far more extensive damage.

Thunderstorms containing these hazards could reach as far north as Springfield, Illinois, and as far south as San Antonio, Texas.

A few heavy and gusty thunderstorms have the potential to ride along the Ohio River Valley into Indiana and northwestern Ohio overnight.

The violent thunderstorms will sweep eastward and continue to pack a punch as they approach the lower Mississippi Valley during Saturday night.

“Damaging winds and hail will be the main threats through the overnight hours,” Strait said.

Areas from Illinois to Texas and Louisiana will not only be hit hard by severe weather, but also flooding rainfall.

“These thunderstorms will produce a large amount of rainfall in a short amount of time and will not be moving very quickly,” Strait said.

The thunderstorms could dump several inches of rain in as many hours, which can quickly overwhelm storm drains and cause streams and rivers to rise.

Additional severe weather will fire up across lower Mississippi Valley and points eastward on Sunday.
