(AP) -- Forecasters are warning of more severe weather, including tornadoes, Tuesday in parts of the South and Midwest hammered just days ago by deadly storms.
That could mean more misery for people sifting through the wreckage of their homes in Arkansas, Iowa and Illinois. Dangerous conditions also could stretch into parts of Missouri, southwest Oklahoma and northeast Texas. Farther south and west, fire danger will remain high.
"That could initially start as isolated supercells with all hazards possible -- tornadoes, wind and hail -- and then over time typically they form into a line (of thunderstorms) and continue moving eastward," said Ryan Bunker, a meteorologist with the National Weather Center in Norman, Oklahoma.
Just last week, fierce storms that spawned tornadoes in 11 states killed at least 32 people as the system that began Friday plodded through Arkansas and traveled northeast through the South and into the Midwest and Northeast.
The same conditions that fueled last week's storms -- an area of low pressure combined with strong southerly winds -- will make conditions ideal for another round of severe weather Tuesday into early morning Wednesday, Bunker said.
Those conditions, which typically include dry air from the west going up over the Rockies and crashing into warm, moist air from the Gulf of Mexico, are what make the U.S. so prone to tornadoes and other severe storms.
The threat of fire danger is expected to remain high Tuesday across portions of far western Oklahoma, the Texas Panhandle, northeast New Mexico and far southeastern Colorado, with low humidity, dry vegetation and wind gusts expected up to 70 mph (113 kph), according to the National Weather Service.
