What is a 'heat dome' and why is it making it so hot in North Texas (and elsewhere) this week? NBC 5's Adrienne Vonn has the answer.
Scorching temperatures brought on by a"heat dome" have taxed the Texas power grid and threaten to bring record highs to the state before they are expected to expand during the coming week, putting even more people at risk.
Record high temperatures around 110 degrees Fahrenheit are forecast in parts of western Texas on Monday and relief is not expected before the Fourth of July holiday, Oravec said.A heat dome occurs when stationary high pressure with warm air combines with warmer than usual air in the Gulf of Mexico and heat from the sun that is nearly directly overhead, Texas State Climatologist John Nielsen-Gammon said.
Nielsen-Gammon said July and August don't have as much sunlight because the sun is retreating from the summer solstice, which was Wednesday.
