Multiday outbreak of severe storms, including large tornadoes, on tap for central US this week
The threat will peak Monday afternoon and night in the Upper Midwest, with AccuWeather severe weather experts warning there is a rare "high risk" for severe storms, complete with the potential for an outbreak of large and destructive tornadoes.
Very large hail expected on the High Plains to end the weekend
The daily onslaught of severe weather has actually been going on for days now in the western High Plains, with daily reports of monster hail, damaging winds and tornadoes dating back to Thursday. The end of the weekend will feature more of the same in this region, which extends from near the Mexican border to near the Canadian border.Have the app? Unlock AccuWeather Alerts™ with Premium+
Deadly hailstones as large as softballs (4 inches in diameter), wind gusts over 60 mph and an isolated tornado or two can occur from West Texas north to the Dakotas late Sunday into Sunday night. For those with outdoor plans to end the weekend in this relatively open area, it's important to identify a substantial structure in case shelter is needed as storms develop and move through.
For many in this zone, Sunday and Sunday night's severe weather threat will finally mark the end of seemingly relentless damaging storms, as the threat area will shift east for the start of the workweek.
Severe outbreak expected Monday in Upper Midwest
As a storm pushes across the Plains and into a warm, more humid air in place over the Midwest, nature's fireworks will commence from Monday afternoon into the night. AccuWeather meteorologists are warning that Monday could be one of the most active days of severe weather so far this season, with a "high risk" for severe weather in place.
"Strong thunderstorms will be enhanced by a fast-moving jet stream," said AccuWeather Meteorologist Alexander Duffus. "That will lend support for the potential of a few intense tornadoes across the region."
The region most at risk for this dangerous weather includes millions and stretches from Iowa into southeastern Minnesota and southwestern Wisconsin, including the metropolitan areas of Des Moines, Iowa, and the Twin Cities of Minneapolis and St. Paul. Travel by air and by road will be impacted by these storms.
"Some of the tornadoes expected to spawn later Monday can be long-lived," said AccuWeather Meteorologist Elizabeth Danco. "This will pose a serious risk, particularly with those that develop after dark when they are more difficult to detect and prepare for."
Residents and businesses in the region, especially the high risk area, should have a plan in place should a Tornado Warning be issued, especially after dark. The AccuWeather App will provide alerts to your cell phone in the event of severe weather.
"Not only will these thunderstorms be capable of producing tornadoes," added Duffus, "but also large hail and widespread damaging winds from Minnesota and Wisconsin through Iowa and northern Missouri."
While the severe weather and tornado threat will begin to wane late Monday night, storms could reach close to Chicago by the predawn hours of Tuesday morning. Regardless of their severity, downpours could slow the morning commute.
The risk of damaging storms will continue through midweek
Monday's potential outbreak of tornadoes will not mark the end of the current episode of severe storms. The risk will shift toward the east and south by Tuesday and Wednesday, impacting millions more, say AccuWeather meteorologists.
On Tuesday, along and ahead of a cold front, the prospect for damaging storms will extend as far east as the Ohio Valley and interior Northeast. Buffalo, Cincinnati, Cleveland, Detroit and Pittsburgh are among the cities that will experience this risk, if only for a day.
Meanwhile, an area that has been no stranger to feisty storms as of late, from western and northern Texas into Oklahoma, can get back into the action again into Tuesday night.
While the risk for tornadoes will be lower compared to Monday and Monday night farther west, storms can still pack a punch, containing hail, flooding downpours and gusty winds.
Yet another day of severe weather can unfold Wednesday, but this time over a much smaller geographic area. The heart of Texas, north to Oklahoma and east into parts of Arkansas and Louisiana will be at risk for strong storms midweek as a frontal boundary settles over the region, providing a focal point for thunderstorm formation.
For those weary residents tired of dealing with this near-daily spat of severe thunderstorms, better days are ahead to begin May, as a quieter weather pattern is expected to take hold. While the risk for damaging storms will not be zero, it will be lower, with only a few gusty and drenching storms expected to shift toward the East Coast beginning Thursday.
While the severe storm threat will lower, there may be an increased risk for flooding, including near the swollen Mississippi River.

Warning About 'Unusual Fatigue' Extended for Millions
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Officials in Wisconsin extended an air quality advisory impacting millions through Friday night as smoke pollution reached levels considered unhealthy for sensitive groups. Breathing in the smoke could worsen preexisting health conditions or cause new issues. People were told to monitor themselves for symptoms such as unusual fatigue, as it could indicate a serious problem, specifically for those with heart conditions. Why It Matters Widespread air quality alerts and advisories were issued across the Upper Midwest on Thursday due to dense wildfire smoke drifting south from Canada. The fine particle pollution—PM2.5—reached levels classified as "Unhealthy for Sensitive Groups" (USG) or worse in numerous counties, prompting warnings from the Wisconsin Department of Natural Resources (DNR). The primary populations at risk include older adults, children, and those with existing heart or respiratory conditions. Officials emphasized that even brief exposure to air pollutants carried in wildfire smoke can lead to exacerbation of underlying medical problems, trigger new symptoms, or prompt emergency medical needs, particularly among vulnerable groups.

Angela Weiss/Getty What To Know The alert took effect at 3 p.m. on Thursday afternoon and will remain in place at least through Friday night at 11 p.m. Nearly all of Wisconsin is currently under the advisory, except for the southwest part of the state. Dozens of counties in northern, central, and southeastern Wisconsin are affected. The advisory covered both rural and urban areas, including cities such as Milwaukee, Green Bay, and La Crosse. The DNR and National Weather Service (NWS) urged residents, especially those with asthma, heart disease, or other lung problems, to reschedule or move activities indoors to minimize exposure. Younger children, older adults, and anyone noticing symptoms such as coughing or unusual fatigue were also advised to limit outdoor activity and seek medical attention if necessary. A Wisconsin DNR spokesperson told Newsweek on Thursday that there have been 11 air quality alerts issued so far this year, nearly triple the number of such alerts issued in 2024, reflecting the increased scope and frequency of wildfire-driven smoke incidents across the Midwest this summer. However, 14 such alerts were issued in Wisconsin in 2023 as Canadian wildfire smoke descended across the U.S. that year. Prior to 2023, there were zero alerts in 2022, and six alerts in 2021. Air quality alerts were also issued in Minnesota and Michigan on Friday. What People Are Saying The Wisconsin DNR spokesperson told Newsweek: "Wildfires occur frequently in the US and Canada throughout the summer months, so we will continue watching for potential smoke impacts as long as there are active wildfires." An NWS air quality alert for Wisconsin: "Canadian wildfire smoke has entered northwest Wisconsin Thursday and will continue to move to the southeast through the remainder of the day. On Friday, smoke will begin moving south. Winds will begin turning southerly Friday night into Saturday, at which point the smoke will begin moving back north. It is possible that the advisory will need to be extended into Saturday for some areas of Wisconsin." What Happens Next The air quality alert was scheduled to last through Friday night, with the potential for extension or geographic adjustment based on updated data from air monitors and forecast models. Residents are encouraged to remain vigilant for updated alerts and to monitor their own health closely, especially individuals in higher-risk categories.

Summer sizzle: NYC, Boston among cities eyeing record highs this week
Summer sizzle: NYC, Boston among cities eyeing record highs this week Intense heat is set to surge into the Northeast late this week, with temperatures climbing high enough in some areas to challenge daily records, according to AccuWeather meteorologists. The brief burst of heat will be fueled by a piece of a larger heat dome anchored over the Great Plains, which is expected to break off and push eastward heading into the weekend. While average temperatures in late July are typically the highest temperatures of the year, driven by intense sunshine, warmer Atlantic and lake waters and long days-this upcoming event may push the upper bounds of historical norms. But, even with routine temperatures typically very high this time of the year, some locations may set daily record highs from Friday to Saturday in parts of the Northeast. Temperatures began to climb on Thursday with widespread highs well into the 80s to mid-90s for the Northeast. Friday will bring the crest of the heat in New England and in the zone from Upstate and eastern New York to portions of New Jersey and northern and eastern Pennsylvania. "In Hartford, Connecticut, the current record of 98 set in 2001 on Friday may be topped," AccuWeather Senior Meteorologist Chad Merrill said. "The record of 99 set in 2016 in Newark, New Jersey, may be swapped by a triple-digit reading." The high temperature in New York City on Friday is projected to approach the record high of 97 from 1999. Meanwhile, in Boston, the high temperature on Friday could come near the record of 96 set way back in 1882, but is forecast to fall a few degrees short with thunderstorms approaching in the late afternoon. "Showers and heavy thunderstorms follow late in the day on Friday and bring a significant cooldown to the upper 70s on Saturday," Merrill said. "This will be a very similar pattern to last month when Boston hit 102 degrees on June 24 and cooled to the upper 70s for highs two days later," Merrill added. Lower humidity will accompany the cooler air in New England and the upper part of the mid-Atlantic on Saturday and may push southward a bit more on Sunday along the Atlantic coast for a time. The temperature boundary will be a focusing point for at least spotty thunderstorm activity this weekend. The storms will extend from parts of the Ohio Valley and Great Lakes states to the mid-Atlantic coast. With more cloud cover around and the likelihood of some local cooling breezes from thunderstorm activity, temperatures may inch downward just a bit over the mid-Atlantic during the weekend but far from the extent enjoyed by millions from this past Monday to Tuesday. Highs in Washington, D.C., will trend downward from near the century mark on Friday to the mid-90s on Saturday and the low 90s on Sunday to put the mid-Atlantic region's cooling trend in perspective. The core of the heat dome will settle southward in the Eastern states over the weekend and will take up residence in the Southeast from Saturday to Wednesday. During this weekend alone, 175 million people will experience RealFeel Temperatures of 100 degrees or higher in the East. The cooling trend in the mid-Atlantic will likely briefly reverse early next week with highs well into the 90s from Monday to the app? Unlock AccuWeather Alerts™ with Premium+ "Much more sweeping changes will come through the Northeast from Tuesday to Wednesday, depending on location, "Merrill said. "A touch of autumn is expected for a few days during the middle to latter part of next week with lower-than-historical average highs that will linger into the first few days in August." The transition could be marked by drenching downpours and gusty thunderstorms. Those with travel plans are encouraged to keep abreast of the forecast for timing and locations of the most severe activity that could lead to disruptions. "In the wake of the storms next week, nighttime temperatures will drop into the 30s and 40s in the Adirondacks and Green and White Mountains with comfortable 60s for much of the Interstate 95 corridor by the end of next week," Merrill said.

Map shows which states are facing dangerous heat
Multiple states are under extreme heat warnings, advisories or watches on Wednesday, July 23 due to a heat dome that is expected to slowly spread east, according to the National Weather Service. The NWS said the remainder of the week features a "strengthening heat dome over the Mississippi Valley today that gradually builds east towards the East Coast by week's end." The weather service said a combination of mid-upper 90s temperatures and humid conditions are a recipe for "oppressive heat indices that range between 110-115 degrees for many areas along and east of the Mississippi River" on Wednesday. By Thursday, July 24, the NWS says the footprint of heat is expected to move east into the Great Lakes and Northeast regions. "While this is not really a record-breaking air mass in terms of high temperatures, some towns and cities will struggle to drop below 80 degrees at night due to the high humidity levels and retention of heat by vast areas of concrete and pavement," AccuWeather Senior Meteorologist Brett Anderson said Wednesday. "For those that only have a fan or open window to keep cool, sleeping will be difficult for some, with a high risk of dehydration." AccuWeather says temperatures will reach 100 degrees from Texas to western Tennessee "just about every day" for the next week or two. See which areas are facing heat and humidity this week. Heat wave affects nearly 100 million: Heat advisories abound as almost 100 million Americans face 'ridiculous' temps National heat index map: See which states feel hottest The map below identifies areas where the heat index is forecasted to reach NWS-defined levels from "Caution" (80 degrees Fahrenheit) to "Extreme Danger" (above 125 degrees). The heat index measures how hot it actually feels when factoring for humidity. Prolonged exposure to a heat index above 80 degrees can lead to fatigue, as previously reported by USA TODAY. As it gets hotter, the risk continues to increase − potentially resulting in heat stroke or even death. Older adults, children, and outdoor workers are generally at higher risk of heat-related incidents. What is an extreme heat advisory? The weather service issues an Extreme Heat Warning when "extremely dangerous" heat conditions are expected or occurring. People in those areas are urged to avoid outdoor activities, especially during the heat of the day, and to check on family and neighbors. An Extreme Heat Watch is issued when conditions are favorable for an extreme heat event but its occurrence and timing are uncertain. People are warned to suspend all major outdoor activities if a warning is issued. What is a heat dome? Heat dome is not actually a scientific term, according to which says the term does effectively describe the "oppressive" high-pressure atmospheric systems that cause warm air to be pushed to the Earth's surface and trapped there for long periods of time. "The dome traps high-pressure air in one place, like the lid on a pot," the website says. "These large zones of hot air result in a combination of blistering temperatures, devastating wildfires, and drought conditions." Gabe Hauari is a national trending news reporter at USA TODAY.
