The next significant round of severe thunderstorms is unfolding as forecast over the High Plains Wednesday and will shift eastward over the Central states later in the week. The multiple-day outbreak could bring a number of strong tornadoes.
Indications are the movement of this storm and strong upper-level winds will interact with a zone of building heat and humidity over the Plains in such a way to produce an outbreak of powerful and dangerous thunderstorms.
Areas from Chicago to Des Moines, Omaha, Kansas City, Wichita, St. Louis, Tulsa, Oklahoma City, Dallas and Little Rock could be impacted by violent storms through late this week.
In addition to the risk of large hail, damaging wind gusts and frequent lightning, there is the risk for several tornadoes. Some of these tornadoes could be particularly long-lived and intense, especially across Kansas, Oklahoma and south-central Nebraska.
Severe weather including drenching rains, large hail, damaging winds and several tornadoes has impacted areas from Texas to Wisconsin.
Look for the potential for these storms, including a few tornadoes, to shift northeastward central and northeastern Oklahoma, eastern Kansas, eastern Nebraska and eastern South Dakota to northwestern Arkansas, much of Missouri, Iowa, Illinois, Wisconsin and southern Minnesota during the latter part of the week.
Another pocket of severe thunderstorms will be over part of the Northeast Wednesday afternoon and evening.
Essentially areas from New York state and northeastern Pennsylvania and northern New Jersey to western and southern New England are at risk for damaging wind gusts, large hail and frequent lightning strikes. There is also the risk of a tornado from the strongest couple of storms.

Flooding Concerns Continue
In addition to the risk for violent thunderstorms, there is the likelihood of flooding problems, especially over parts of the central Plains to the Midwest that have already received heavy rain over the Memorial Day weekend and/or will do so into the end of this week.
Flooding problems have expanded from that of flash and urban concerns to major rivers centered on Iowa.
Portions of states that could be hit hard with flooding problems not only at the beginning of this week, but the end of the week include Iowa, Nebraska, Kansas, Missouri and Illinois.
A warmer weather pattern is forecast for much of the Central and Eastern states, while temperatures should throttle back in the Northwest during the middle of August.
