Rounds of severe storms to continue in central and eastern US
Multiple rounds of severe weather will stretch across portions of the United States, which can put some communities at risk during this third week of June.
Severe thunderstorms spawned multiple tornadoes across Nebraska and Minnesota on June 16.
Severe thunderstorms and torrential downpours will be a common sight across the north-central United States to the East Coast this week, causing widespread disruptions and, in some cases, may endanger lives and property, AccuWeather meteorologists warn.
Thunderstorms will erupt daily and consolidate as the jet stream moves along. Where the sun stays out for a few hours, especially midday, it will be enough to make some of the storms severe. In some cases, the storms may become so intense as to produce tornadoes.
Because of the high amount of water in the atmosphere and the saturated state of the ground in some areas, flash flooding may pose the most significant danger and risk to property.
As storms erupt or approach the major metro areas, airline delays and ground stops will increase. Motorists should be prepared for delays on the highway due to poor visibility and ponding in areas that drain poorly.
Storms to progress through Midwest, southern Plains at midweek
The likelihood of severe weather will progress to the south and east over the central U.S. on Wednesday.
The midweek risk of severe thunderstorms will extend from the central part of the Lower Peninsula of Michigan, western Pennsylvania and West Virginia to north-central Texas.
A greater concentration of severe weather on Wednesday afternoon and night will include Dayton and Toledo, Ohio; Indianapolis and Evansville, Indiana; and St. Louis and Springfield, Missouri. Chicago, Detroit, Milwaukee and Cleveland, will also have severe thunderstorms in part of their metro areas.
The area bounded by east-central Illinois to central and northwestern Indiana, northwestern Ohio and the southern part of the Lower Peninsula of Michigan will be a prime spot for several tornadoes during Wednesday afternoon and evening. Some of the twisters could be difficult to spot due to low clouds and rain.
Severe storms to blast parts of eastern US
Locally severe thunderstorms may affect parts of the mid-Atlantic, Interstate 95 zone on Wednesday.
Then the risk of severe thunderstorms in a portion of the Eastern states will ramp up once again on Thursday. The risk of severe weather will be focused on the mid-Atlantic region, but will also include a large part of the central Appalachians and New England.
Thursday's eastern severe weather threat will extend from Vermont, portions of New Hampshire and northern New York state to the Carolinas and the northeastern tip of Tennessee.
Within this zone, the focus of severe weather is anticipated in portions of the Hudson, Connecticut, Susquehanna, Lehigh, Delaware and Potomac Valleys and includes the major cities of Washington, D.C.; Baltimore and Hagarstown, Maryland; Trenton, New Jersey; Philadelphia, Harrisburg, Allentown and Wilkes-Barre, Pennsylvania; Wilmington, Delaware; Albany and Poughkeepsie, New York, and Burlington, Vermont.
Late in the week and this weekend, as a dome of heat builds over the Plains and Mississippi Valley, complexes of thunderstorms are likely to form along the rim of the sweltering conditions.
Similar setups in the past have produced long-lived, damaging thunderstorm wind events, called derechos.
AccuWeather meteorologists will monitor that situation closely for potential impacts from the northern Plains to the Great Lakes and into parts of the Appalachians and Atlantic Seaboard.
