Meteorologist Grant Johnston updates the hot forecast for Wednesday, June 27, 2012.
The mercury hit 100 degrees at Dallas-Fort Worth International Airport for the first time this year on Sunday afternoon -- since then it's only gotten hotter.
The high reached 104 degrees Monday, 106 on Tuesday and 102 Wednesday. NBC 5 Chief Meteorologist David Finfrock said North Texas can expect temperatures to hover above 100 for the rest of the work week, including a forecasted high of 101 degrees on Thursday and 100 on Friday.
By this weekend, temperatures may drop below 100 to 99 on Saturday and 97 on Sunday.
Conservation Requested During Excessive Heat
On Wednesday, just like on Tuesday, ERCOT is asking all Texans to conserve power between the hours of 3 p.m. and 7 p.m.
On Monday, Texans set a record for the load on the grid with 65,047 megawatts. On Tuesday, when temperatures hit 106, another record was set with Texans pulling 66,583 megawatts.
The actual load on the grid Wednesday is, so far, outpacing the load on Tuesday. So conservation efforts are critical.
Heat Keeping EMS Crews Busy
The triple-digit temperatures are keeping MedStar crews busy.
Contrary to other news reports, there was not a heat-related death in Tarrant County Tuesday. Still, MedStar personnel responded to nine heat-related emergencies. MedStar spokesman Matt Zavadsky said the number of heat-related emergencies is up this month compared to the same time last year.
"So far this month, we've responded to 58 heat-related emergencies," he said. "Last June, through the 26th, we had only responded to 50, so we're a little nervous what the rest of the summer is going be like here."
Police departments across North Texas are encouraging everyone to regularly check on seniors and the less fortunate.
"Any type of medical concerns that a person can face at a younger age, with the heat being so hot, you can double that for a senior," said Fort Worth police Officer Julie Cox.
Road Crews Taking Extra Precautions
Road construction crews are taking precautions while working in the heat.
Trinity Infrastructure provides shade tents so its workers on the LBJ Express Project can spend plenty of time out of the sun.
"On a daily basis, we come out here and ensure all of workers have a shaded area, especially with this weather that's about 100 degrees," Jason Coronado said.
Workers also have a buddy system to keep an eye out for signs of heat stroke.
