Severe storms to pummel central US through midweek


While a major outbreak of severe weather is unlikely, severe thunderstorms that erupt from the High Plains to the Upper Midwest can pack a punch through midweek.

A multiple-day severe weather threat to lives and property exists for the North Central states as a batch of cool air from the western United States moves eastward.

People should keep a close eye on the sky and monitor severe weather bulletins. As the storms advance and approach area airports, the risk of airline delays will increase.

"Into Monday night, storms over the northern High Plains will bring the risk of large hail and damaging winds to the northern High Plains," according to AccuWeather Lead Long-Range Meteorologist Eddie Walker.

Farther east, near the Interstate 90 corridor, storms along the boundary between August-like heat and seasonable air will bring localized torrential rainfall and high winds.

During Tuesday, the threat for severe storms will extend along an approximate 1,200-mile-long swath from southern Manitoba, Canada, to western Texas.

The most concentrated area of severe storms will be from near the United States and Canada border to northeastern Nebraska.

"On Tuesday, storms over the northern Plains will bring a widespread risk of damaging winds, hail and localized flooding," Walker said.

"Farther south over the Plains, there will be the potential for isolated tornadoes with the strongest thunderstorms late Tuesday, prior to evolving into straight-line strong wind threat Tuesday night," he said.

On Wednesday, the primary focus for severe weather will be over the Upper Midwest, perhaps centered on Wisconsin. Storms in this area on Wednesday will carry the potential for strong wind gusts, flash flooding and hail.

However, local storms may reach severe levels as far to the east as the central Appalachians and mid-Atlantic on Tuesday and Wednesday and as far to the south as Oklahoma and Arkansas at midweek.

As is the case with any severe thunderstorm, there is the slight chance of a tornado being spawned.

Those spending time outdoors should be prepared to move indoors, away from windows. Get to indoor shelter at the first clap of thunder or the first distant flash of lightning.

While heat remains the leading cause of weather-related fatalities worldwide, lightning claims 30 people annually in the U.S., according to NOAA Lightning Safety Specialist John Jensenius.

If in a remote area, a car or truck with a roof will offer substantial protection from a lightning strike. Never seek shelter under a tree or small grove of trees as lightning often strikes the highest point in a general area.

Over this past weekend, some communities over the northern U.S. were hit hard with damaging hail and high winds.
