New storm threat follows deadly tornadoes
A meteorologist discusses a new threat for severe weather brewing in the Midwest and heading up to the Northeast.
A "severe weather threat" could fuel tornadoes in parts of the Midwest.
Rain could fall on event planned Monday at Arlington National Cemetery.
ARLINGTON, Va. − The weather across a broad range of the nation may not be too cooperative with organizers of parades and other events honoring fallen war heroes − or just planning get-togethers with family and friends − this Memorial Day weekend.
A "shortwave" over the Rocky Mountains will conspire with a frontal system to"provide support for heavy rain and thunderstorms in a moist and unstable environment" across parts of the central U.S. this weekend, National Weather Service meteorologist Jennifer Tate wrote in an extended forecast discussion. Flash flooding is possible, she said.
Shortwaves are pockets of energy that move east, generally at speeds between 20 mph and 35 mph.
AccuWeather warns that a "severe weather threat" will hover over portions of the southern Plains and can expand to the north on Friday. Thunderstorms that could pack high winds, large hail, flash flooding and a few tornadoes will extend from parts of Texas through Oklahoma, Kansas, Colorado and Nebraska, AccuWeather says in its extended forecast.
"The storms will slowly creep eastward across the South Central states as the weekend progresses," says AccuWeather senior meteorologist Alex Sosnowski. The target area could include parts of the Mississippi Valley and the Gulf Coast Saturday and Sunday and stretch into the Southeastern states by Memorial Day.
Late seasonnor'easter is brewing, could bring dangerous winds to New England this week
Developments:
∎ New York should be mostly clear and cool, with highs in the upper 60s. Farther south, summertime scattered storms are likely across the Florida Peninsula through the weekend, the weather service said.
∎ Los Angeles should see mostly sunny skies throughout the weekend, but the Northwest may see renewed precipitation chances.
Memorial Day weekend draws large crowds to Arlington National Cemetery outside Washington, D.C. Saturday should be clear and cool, with a high in the upper 60s, the weather service says. The chance of rain slowly builds Sunday through Monday.
Monday is when scheduled events at the cemetery include a concert by the United States Marine Band and the U.S. Navy Band Sea Chanters, a wreath-laying at the Tomb of the Unknown Soldier and a parade of colors by Veterans' organizations and remarks from special guests.

Massive wildfire becomes California's largest blaze of the year
Rising temperatures are posing new challenges for firefighters who have made incremental progress against a massive wildfire in central California which has become the biggest blaze in the state so far this year. More than 870 remote homes and other structures at the northern edge of Los Padres National Forest are threatened by the Gifford Fire, which grew slightly overnight after burning out of control for days. The fire has scorched at least 131 square miles of Santa Barbara and San Luis Obispo counties, with just 9% containment. It surpassed the 126 square mile Madre Fire, which erupted last month in south-eastern San Luis Obispo County, as the state's largest fire of 2025. Crews working in steep, inaccessible terrain will be dealing with temperatures around 35C on Wednesday and above 38C on Thursday, said Captain Scott Safechuck with Santa Barbara County Fire Department. 'We have hot weather, and we have low relative humidity,' he said. 'So we expect extreme fire behaviour.' Luckily, winds are expected to remain relatively calm, he added. Wildfire risk will be elevated through the weekend across much of inland California as the heatwave intensifies. The southern part of the state has seen very little rain, drying out vegetation and making it 'ripe to burn', the National Weather Service for Los Angeles warned in a statement. Temperatures around 38C are forecast for the Sacramento Valley. More than 2,200 personnel are battling the Gifford Fire, which grew out of at least four smaller fires that erupted on Friday along State Route 166, forcing closures in both directions east of Santa Maria, a city of about 110,000 people. The causes of the fires are under investigation. Flames are racing through a vast, mostly unpopulated region that includes forests, ranches, large canyon properties and agricultural parcels growing wine grapes and strawberries. The weather service warned of health risks from spreading smoke that could affect much of south-west California. Officials reported four injuries, including a firefighter who was treated for dehydration. Over the weekend, a motorist was treated in hospital for burn injuries after getting out of his vehicle and being overrun by flames, and two contract employees assisting firefighters were hurt when their all-terrain vehicle overturned.
