Multiday severe weather threat covers millions from Texas to Midwest for large hail, possible tornadoes
The SPC has placed nearly 18 million people in a Level 2 out of 5 risk on its severe thunderstorm risk scale on Thursday, and the threat includes cities such as Dallas-Fort Worth in Texas and Des Moines, Iowa.
KANSAS CITY, Mo. – The threat of powerful thunderstorms continues to grow across the nation’s midsection this week as millions from Texas to the Midwest and Great Lakes are bracing for yet another multiday severe weather threat.
The threat began on Tuesday in Missouri but by Thursday, the severe weather is expected grow and expand to include tens of millions of people from Dallas to Chicago.

Severe thunderstorm activity is expected to really get cooking on Wednesday, the FOX Forecast Center says.
Storm coverage, as well as the severe weather threat, will ramp up during the day as moisture, atmospheric energy and wind shear will be much higher.

There are two areas of concern on Wednesday; the first along a warm front draped across Missouri and Kansas. This first round of storms is expected to develop across northeast Kansas after 5 p.m. CT before they expand into Nebraska, Missouri and Iowa.

NOAA's Storm Prediction Center (SPC) has placed nearly 3 million people across the region in cities such as Kansas City in Missouri and Topeka in Kansas in a Level 2 out of 5 risk on its 5-point severe thunderstorm risk scale.
The second area of concern is from southeastern Kansas into extreme northeastern Texas, where atmospheric conditions will also support thunderstorm development. However, the FOX Forecast Center says a cap, or "lid" in the atmosphere, could block storms from forming at all in that area.
Any severe storms that do develop Wednesday are capable of large hail, damaging wind gusts over 60 mph, and a few tornadoes.

Thursday could be the main event in terms of multiday severe weather threat

Thursday could be the day when the bulk of severe weather action will kick off, with millions of people from Texas to the Great Lakes region at risk of potentially dangerous extreme weather.
The SPC has placed nearly 18 million people in a Level 2 out of 5 risk on its severe thunderstorm risk scale Thursday, and the threat includes cities such as Dallas, Fort Worth, Arlington, Plano, Garland and Waco in Texas, as well as Springfield and Jefferson City in Missouri and Des Moines in Iowa.
The FOX Forecast Center says the day will once again focus on two main areas of potential development, with the first across southern Iowa and northern Missouri into central Illinois and the second farther south from eastern Oklahoma and Texas into Louisiana and Arkansas.
Atmospheric conditions near the area of low pressure and warm front will likely result in the development of supercell thunderstorms across northern Missouri, Illinois and southeastern Iowa.
Thunderstorms that develop along and south of the warm front will be capable of producing hail larger than 2 inches, wind gusts higher than 60 mph and some tornadoes.
To the south, severe thunderstorms should explode ahead of a dryline across Oklahoma and northeastern Texas - including the Dallas-Fort Worth area - during the early afternoon hours.
Any severe thunderstorm will carry a threat of large hail, damaging wind gusts over 60 mph and possible tornadoes. But the FOX Forecast Center says how thunderstorms evolve into the Thursday evening hours is still unclear.
If those storms join together and form a squall line, then the threat for damaging straight-line winds will increase, before thunderstorms weaken and fall apart overnight into Friday.
