Showers and thunderstorms will move into the Plains, while also continuing across the East Coast on Friday. A low pressure system over the Rocky Mountains will persist on its eastward track and move into the Plains. Flow around this system will create northward flow, pulling abundant moisture and energy in from the Gulf of Mexico. This will allow for scattered showers and thunderstorms to develop across the Southern Plains again on Friday, spreading northward through the Central and Northern Plains. There is a slight chance that these storms will turn severe across northeastern Colorado, into western Kansas and Nebraska. Large hail and strong winds are likely in these areas, with possibly a tornado or two.

A strong, large storm will continue making its way through the eastern third of the country on Thursday, producing more, active weather east of the Mississippi Valley. While the active weather is not likely to produce the severe thunderstorms that have greeted the country over the past several days, scattered thunderstorms will be likely, especially in the Southeast. In addition, moderate to occasionally heavy rain will move through the Northeast, followed by cool showers in the Ohio Valley and Upper Midwest.

After an active severe weather pattern during the beginning of the week, cooler and relatively calmer weather conditions will return to much of the Central U.S. on Wednesday as the trough of low pressure impacting the region moves to the East. As the trough progresses, an associated low pressure system will reorganize near southern Lake Michigan and will continue northeastward across Michigan toward the Lower Great Lakes through Wednesday evening. Expect rain showers to continue across the Upper Midwest into areas of the inland Northeast throughout this transition. Meanwhile, the system's associated cold front will trail southwestward from the low across the Ohio and Tennessee Valleys through the Lower Mississippi Valley and into the Southern Plains. Favorable energy and environmental conditions ahead of the cold front combined with ample moisture from the Gulf of Mexico will set the stage for shower and thunderstorm activity through the day. Areas just east of the advancing cold front will experience the heaviest amounts of precipitation, with areas of flooding and flash flooding possible in parts of eastern Texas and Louisiana. As the cold front continues eastward, areas of the Lower Great Lakes into the Ohio and Tennessee Valleys are at slight risk of severe thunderstorm development through the evening. Severe storms in these regions may become capable of producing damaging wind gusts, marginally severe hail, and even a few tornadoes during the evening hours.
