Storms moving through the central part of the United States on Tuesday brought with them the potential for damaging winds and a few tornadoes, and the National Weather Service warned of a particularly high risk of what it called “giant” hail around Dallas.
Emergency officials in Palo Pinto County, west of the Dallas-Fort Worth area, said there had been reports of possible tornado damage across a large swath of Mineral Wells, Texas, a city about 50 miles west of Fort Worth. Officials had also received reports of some injuries, including people who had been transported to a hospital.
It was not immediately clear how many people had been hurt, nor was the extent of their injuries.
The National Weather Service had received reports of tree damage as well as reports of hail the size of golf balls in the Mineral Wells area.
Images and videos emerging on social media showed felled trees, as well as buildings with roof damage and one building that appeared to have its windows blown out.
The forecast was the latest in a nearly weeklong sequence of stormy days in the region. On Monday, a man died in Michigan when a tree fell on him in high winds, and severe storms brought down trees and power lines in the Midwest.
The threat on Tuesday was focused over portions of the Midwest, Southern Plains and Southeast, where a tornado watch covered a broad area from North Texas to West Tennessee and northern Alabama. By early Tuesday afternoon, a few brief tornado warnings had been issued.
Forecasters were especially focused on an area of North Texas, where they warned that hail as large as a softball could fall from the sky on Tuesday afternoon and evening.
“Hail that size can shatter a window,” said Allison Prater, a meteorologist with the Weather Service office in Fort Worth.
Judge Clay Jenkins of Dallas County, the top elected official there, told residents on social media to have several ways of receiving weather alerts on Tuesday.
“This afternoon and evening have the chance to be VERY active for severe weather,” Judge Jenkins wrote on social media. “All hazards are possible.”
Several rounds of thunderstorms are expected into the evening, bringing a risk of damaging winds, large hail, heavy rain and a few tornadoes. Some could intensify into highly organized, long-lived supercell thunderstorms.
Thunderstorms are fueled by rapidly rising columns of warm, moist air known as updrafts. The updraft lasts about 30 minutes or less in a typical thunderstorm and can endure for over an hour in a supercell. Giant hail is most often a product of a supercell.
The thunderstorm threat on Tuesday ranged from a Level 1 to 3 out of 5 across a broad area of the Southern Plains and Southeast, but in the afternoon, forecasters bumped Dallas up to a Level 4.
“The main concern with the storms today in that area is the potential for very large hail and that’s what drove that upgrade in the risk category,” said Harry Weinman, a meteorologist with the Storm Prediction Center. “We also have concern for damaging winds, and we can’t rule out tornadoes as well.”
Quieter weather is expected after Tuesday. While there is still a chance for severe storms on Wednesday, the risk level is much lower than it has been in recent days.
