FLASH: AccuWeather estimates that about 44_ people live in the risk zone for severe thunderstorms Sunday and into the week.
An active Pacific Ocean storm train will set the severe weather outbreak into motion. At the same time, warmth and moisture are forecast to build over the Plains and Mississippi Valley. A strong jet stream will stir the pot for severe weather soon after the storms cross the Rockies and come in contact with the warm and humid air.
The rounds of severe weather are coming at a time when travel and graduations begin to ramp up. Whether staying at home or on the road, be sure to stay up to date on the severe weather potential.
The tornado and high wind risk is likely to extend to after dark, which will add to the danger. It is possible that a few of the tornadoes may be large, violent and on the ground for more than a few minutes.
Large hailstones likely to be produced during the strongest storms can cause serious injury, kill livestock and cause substantial property damage.

These storms have the potential to bring very large hail and isolated tornadoes, as well as wind gusts to 80 mph and highly localized flash flooding.
On Sunday, the main threat of severe weather, including isolated tornadoes, will focus over the middle part of the Mississippi Valley.
Severe storms are likely to extend from southern Arkansas and northwestern Mississippi to southeastern Iowa, central Illinois and western Indiana.
However, there is a chance that severe weather will extend as far north as the central part of Wisconsin and as far south as southern Louisiana and part of the Texas coast.
New round of severe weather to begin Monday
As another storm emerges from the Rockies, a new round of severe weather is likely to be sparked over the central and southern High Plains during late Monday and Monday night.
During Tuesday, the severe thunderstorm risk should once again advance eastward across the central and southern Plains and may reach from central Texas to northern Iowa and eastern Nebraska.
Similar to the round of severe weather into this week, the next round has the potential to produce tornadoes.
As is often the case during late May, and especially during the amplified weather pattern, more rounds of severe weather are expected to follow beyond early this week.
The repeating rounds of thunderstorms and the heavy rain they contain are likely to elevate the risk of urban and small stream flooding, as well as send a new surge of water into area rivers and major waterways.
