Severe Weather Moving Through U.S. South, Midwest On Monday

ACROSS AMERICA — A large storm system moving across the United States ahead of a cold front likely will bring large hail, damaging winds and flooding rains, and it could even spawn tornadoes in the South and Midwest, according to forecasters.

The system stretches from Texas through parts of the South and Midwest up to the Northeast.

Severe weather began in areas in Oklahoma, Kansas, Missouri and Iowa over the weekend, with hail as large as baseballs being spotted in the plains, according to AccuWeather.

Those storms moved into parts of north Texas, Arkansas and Tennessee on Sunday night, and forecasters expect thunderstorms to "train" — or stall and redevelop — in those same areas Monday as warm and humid air from the Gulf of Mexico slows the cold front, according to AccuWeather.

That likely will mean heavy rainfall for many of those areas, especially in Texas, where as much as 3 inches of rain is expected in Waco, up to 2 inches in the Houston area and another inch in areas around San Antonio, according to The Weather Channel. The rainfall will be welcome in large parts of Texas and Oklahoma, which are under extreme-to-exceptional drought conditions, according to the U.S. Drought Monitor.

A half-inch to an inch or rainfall is expected Monday in areas of the South and Midwest, including Louisiana, Mississippi, Alabama, Tennessee, Kentucky, Ohio and Indiana.

Flash flooding is possible throughout a stretch from Texas to the Midwest on Monday. The biggest threats for isolated severe weather will be in southeastern Texas and the Ohio Valley through Monday night, according to AccuWeather. Damaging hail and winds are most likely in any severe thunderstorm that develops in the system, but isolated tornadoes could also be possible, according to forecasters.

The system is expected to move into the Carolinas by Tuesday.
