The city of Lewisville had record-setting heat for four days straight late last week. The DFW Metroplex is nearing the end of its worst heat wave since 2011, which has gone on for close to two weeks now, according to forecasts.

A heat wave hit the metroplex early last week and has kept temperatures in the 100s since. Lewisville hit 110 Sunday afternoon, breaking the day’s record high for the fourth consecutive day. Both Dallas and Fort Worth also broke records for five consecutive days and four consecutive days dating back to last week, respectively.

The heat is expected to finally break with a stormfront this weekend.

The heat has meant record amounts of  power usage for the Electric Reliability Council of Texas (ERCOT) as people try to cool their homes. According to ERCOT, their demand had reached 73,259 megawatts on Thursday, which had topped the all-time high of 72,192 on Wednesday. Prior to these days, the highest usage had been 71,110 megawatts in August 2016, according to the Longview News-Journal.

This type of heat can be dangerous for people and pets, and without proper precaution can cause heat exhaustion. Heat strokes occur when a person reaches the body temperature of 104 degrees. Signs of heat exhaustion include headache, nausea, dizziness and faintness. If you believe someone may be suffering from heat exhaustion, move them to a shaded or air-conditioned area and have them drink cooled water and lay down until their temperature lowers. If a person’s symptoms do not improve within an hour or get worse, contact a doctor.
