Straight-line winds of 85 mph caused damage in Greenville; Heat index values soar

The severe storms are gone and summer is arriving with a vengeance.

In Greenville, National Weather Service survey teams determined straight-line winds of 85 mph that likely included “a powerful rear-flank downdraft” caused most of the damage Wednesday. Greenville is home to about 29,000 residents about 45 miles northeast of Dallas.

Teams are still assessing other damage in Hunt County.

Local officials reported the severe storm that hit Greenville caused widespread tree and roof damage, according to the Associated Press. There were no immediate reports of injuries.

The storms missed most of the Dallas-Fort Worth area with Collin and Johnson counties seeing severe weather.

“There wasn’t enough lift to get storms going in most of the Dallas-Fort Worth area,” National Weather Service meteorologist Patricia Sanchez said. “It’s tricky in the summertime to predict these storms.”

Heat advisory

The National Weather Service has also issued a heat advisory for Thursday with high temperatures in the upper 90s and heat index values between 105-110 across Tarrant County.

“It’s humid. It’s hot,” Sanchez said. “People need to take precautions.”

The heat advisory is in effect until 8 p.m. Thursday, though heat indexes are expected to climb above 100 on Friday as well.

There will be a slight break in the heat this weekend with high temperatures dropping back into the low 90s and rain chances returning.

On Wednesday, MedStar crews treated seven patients for heat-related illness. All seven cases were serious enough to require transport to area hospitals. There was also one call for a child in a hot car. The child was treated on the scene but not taken to the hospital.

Since May 1, a total of 80 patients with heat-related illness have been treated and 52 were sick enough to be taken to area hospitals.
