The severe weather that killed 32 people across the South and Midwest over the weekend has passed, but another thunderstorm hit much of the same area on Tuesday.
A strong, fast-moving, and potentially powerful, long-range tornado with a strong wind, lightning, hail and rain front will strike the eastern third of the country through Tuesday afternoon and evening, Federal Forecasters said. He said he would attack.
The most violent storms are likely to occur after sunset, making tornadoes twice as likely as daytime twisters.
Severe storms are expected Tuesday into the evening across a wide area extending south from the Great Lakes and into northern Texas. The storm will begin early in the morning in Iowa and Illinois, but not until after midnight in parts of Oklahoma and Arkansas.
In the southern half of the risk area, most storms occur at night. Heavy hail and winds in excess of 75 mph are possible.
Forecasters say the explosive collision of cold air from the north with relatively moist and warm air from the Gulf of Mexico will create a tornado as strong as EF-2, with sustained winds of 111 mph. There is likely to be.
If gale winds change direction and swoop high above, supercells form, and mesocyclones produce distinct vertical, thundering, and rotating storms, the system will create fertile conditions for tornadoes, they say. Said.
Cities with the highest risk of strong tornadoes include Chicago, Detroit, Indianapolis, and Toledo, Ohio.
“If they form, they can create very large and powerful tornadoes,” said Melissa Byrd, a meteorologist at the National Weather Service.
An estimated 42 million people are at risk of severe storms on Tuesday, according to NBC News’ weather unit. That will change to about 62 million on Wednesday as the storm system stretches from northern Michigan to northern Louisiana.
According to the National Weather Service, the worst weather is likely to occur along a vertical line from Des Moines, Iowa to Little Rock, Arkansas.
Springfield, Missouri is subject to the worst front, after Iowa’s Cedar Rapids, Davenport, Waterloo and Iowa City. The Weather Service has described the risk of severe thunderstorms as moderate.
“Strong tornadoes and particularly destructive winds are expected,” the Japan Meteorological Agency said in its outlook report on Monday. “Both afternoon and nighttime possibilities exist in various regions, including the risk of dangerous nighttime tornadoes.”
The largest city closest to the most intense weather expected is St. Louis, where thunderstorms and even tornado activity are not uncommon during May. However, this time the region is taking a hit.
Byrd, who is based at the Meteorological Service Office in nearby St. Charles, said, “We could see perhaps two bad weather events this afternoon and into tomorrow night.”
In the states north and west of thunderstorm activity, Wyoming, the Dakota and Minnesota, the same front could trigger blizzard conditions and record amounts of snow in April, according to the Bureau of Meteorology. and NBC News’ weather unit.
Experts say the mainland and southern United States, in particular, are facing a climatic disaster as cold fronts from storms in Canada and the Pacific move south and east, colliding with tropical air from the Gulf of Mexico, creating catastrophic weather each year. I have been hit.
But climate change may be exacerbating extreme conditions, resulting in colder cold fronts, stronger tornadoes and bigger hail in the spring, and longer, hotter streaks in the summer. They say it can happen.
In mid-March, the National Atmosphere and Ocean Administration’s spring outlook predicted moderate to severe flooding from Minneapolis to St. Louis, but drought persisted in the northern and central plains.
“Climate change is pushing both wet and dry seasons to extremes,” said NOAA Administrator Rick Spinrad in a statement.
