Grant Cruise, a spokesman for Oncor, a Texas electricity provider, said at a news conference that crews were assessing the damage on Tuesday. He said the response was more a matter of “complete reconstruction” rather than the simple repair of downed power lines.
“We are asking for your patience,” he said.
Heath Montgomery, a spokesman for Dallas Fort Worth International Airport, said that the Federal Aviation Administration grounded flights there from 5:30 a.m. to 8 a.m. About 90 flights were canceled for the day, and a number of flights were diverted to other airports, he said.
Beyond Texas, Kentucky is expecting a reprieve in the coming days, as the National Guard and forestry workers continue to clear downed trees and dangerous debris from powerful storms that killed four people over the weekend. The Weather Service in Louisville said that mostly dry weather was expected in the coming days, with no rain in the forecast until the weekend.
Severe storms were possible across Central Oklahoma on Tuesday, beginning early in the morning and shifting south through the afternoon, according to the Weather Service office in Norman, Okla. In Southern Oklahoma, raging storms with large hail had become less intense by early Tuesday morning, the Weather Service said. Still, hail the size of golf balls and damaging winds of up to 60 m.p.h. were possible later in the day. Two people were killed north of Tulsa over the weekend as severe storms swept in.
After a wet, windy and disruptive Memorial Day in the Mid-Atlantic and Northeast, sunny, summerlike conditions returned on Tuesday morning with highs in the low-to-mid 80s.
