Thunderstorms could bring hurricane-force winds to parts of South Dakota, NWS says
A line of severe thunderstorms is expected to move across eastern South Dakota in the late afternoon July 28, potentially bringing heavy rain and hurricane-force winds to the region. Severe weather is expected to occur between 4 and 7 p.m. in central South Dakota, between 7 and 10 p.m. along Interstate 29, and between 9 p.m. and midnight in southwest Minnesota, according to the National Weather Service. The main concern will be wind gusts of 70 mph or more, though large hail and a few tornadoes are also possible, the weather service said. Thunderstorms could combine to become a derecho as they drift over eastern South Dakota, according to the National Weather Service's Weather Prediction Center. Heavy rainfall over saturated ground could also lead to scattered instances of flash flooding in the region. The area most at risk for high winds was north of Interstate 90, including Aberdeen, Brookings, Huron and Watertown. The weather service said it "highly advised" securing any items that might easily blow away before the storms arrive. A portion of southeast South Dakota was already under an extreme heat warning, with the heat index expected to reach 107 degrees by Monday afternoon in Sioux Falls. What is a derecho? A derecho is a widespread, long-lived wind storm associated with a band of rapidly moving showers or thunderstorms, according to the National Weather Service. A derecho can produce destruction similar to tornadoes, and the term "straight-line wind damage" is sometimes used to describe derecho damage. "By definition, if the wind damage swath extends more than 240 miles and includes wind gusts of at least 58 mph or greater along most of its length, then the event may be classified as a derecho," the weather service says.

Forecasters warn a rare derecho with hurricane-force winds could plow through part of the US
Damaging and potentially destructive thunderstorms are set to roar through the northern Plains on Monday, fueled by intense July heat and humidity. There's increasing concern that some of these storms could morph into a derecho – a long-lasting line of storms that delivers powerful damaging wind gusts consistently across a few hundred miles of land. Derechos are rare, typically occurring once or twice per year across the US, usually during the summer months in the Midwest and Mississippi–Ohio Valley corridor. As a result, there's a Level 4 of 5 risk of severe thunderstorms across parts of South Dakota and Minnesota Monday, according to the Storm Prediction Center. That heightened risk level is mainly due to the threat of gusts greater than 80 mph. The winds could be comparable to those found in a Category 1 hurricane, albeit in shorter bursts. Category 1 hurricanes have sustained winds of at least 74 mph and stronger gusts. A few tornadoes could also spin up inside the line of already dangerous storms. Parts of North Dakota, South Dakota, Nebraska, Minnesota and Iowa surrounding the Level 4 area are under a level 3 of 5 risk of severe thunderstorms that could also bring damaging wind gusts, hail and even a tornado. A larger Level 2 of 5 risk extends across much of the northern Plains and parts of the Midwest Monday. The main threat is once again damaging wind, but isolated tornadoes or large hail cannot be ruled out. A few severe thunderstorms were already rumbling near the Montana-North Dakota border early Monday. Storms will continue to develop in the area throughout the morning and eventually track entirely into the Dakotas by the early afternoon. From there, storms will tap into plentiful heat and humidity and strengthen considerably. The potential derecho is expected to reach its peak strength sometime in the late afternoon or early evening in eastern South Dakota before tracking into Minnesota. The line of storms is expected to gradually lose its strength overnight before it reaches the Great Lakes. Monday's storms will be just the latest to hit the northern Plains. Over the weekend, a cluster of severe storms and tornadoes moved through the region, resulting in numerous wind and hail reports across eastern South Dakota, southern Minnesota and northern Iowa. Three tornadoes were reported in rural areas. Golf ball-sized hail, downed trees and flash flooding were reported across the Minneapolis-St. Paul area in Minnesota. Saturated soils from weekend rain are also fueling a flash flooding risk Monday in the northern Plains, particularly across low-lying and urban zones. The Weather Prediction Center has identified a Level 2 of 4 risk of flooding rain across the region. The severe storm threat lessens to a Level 1 of 5 risk Tuesday as stormy weather shifts south and east into the central Plains and Great Lakes. Those storms will bring yet another chance for flooding, this time in the central Plains.

Searing Heat Threatens Grids and Health Over Nearly Half the US
Nearly half the US will wilt under hot, sticky conditions through the bulk of the week as temperatures and humidity soar from Chicago to New York City and New Orleans, boosting power demand and raising health risks. Heat advisories and extreme heat warnings stretch from Nebraska to Long Island and from New Hampshire to northeast Texas. Monday's high in Central Park is forecast to reach 94F (34C), but with humidity it will feel closer to 100F or more. Chicago will likely reach 91F and feel closer to 102F, the National Weather Service said.
