Heatwave Forecast

(forecast by Michael Huguet)

We’re looking at high temperatures reaching the triple digits in western Texas and eastern New Mexico on Wednesday, with temperatures in the high 90s (℉) going as far north as the Dakotas. On Thursday, much of this area will cool down, but we’ll continue to see temperatures in the high 90s throughout western and Central Texas up to Kansas.

Friday, the West Coast becomes the hotspot, with triple-digit temperatures in the desert Southwest and much of the Central Valley in California. In addition, there’ll be isolated patches of 100-degree heat as far north as eastern Washington.

Saturday will get even hotter, especially in the Central Valley, with temperatures climbing above 110℉ as far north as Redding, Calif. Sunday will still be hotter in the same areas and may approach record levels in Portland, Ore. (Portland has a record high of 107℉, and both the GFS and Euro are putting it in the 110+ range). Sweltering heat continues on the west coast well into the week, and 100+ degree temperatures spread into lower elevation areas of Idaho, Montana, and Alberta as well.

As much of the U.S. endures a heatwave, it’s essential to stay safe during these intense temperatures. According to the Centers for Disease Control (CDC), heat-related deaths are one of the deadliest weather-related health outcomes in the U.S. 

Protecting Yourself from Heat-Related Illnesses

The CDC reports that about 700 people die from extreme heat in the U.S. each year. 

Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and even death. The highest risk people include those above the age of 65, children younger than two, and those with chronic diseases or mental illness. 

Take These Steps to Stay Cool

  1. Stay in air-conditioned buildings as much as you can. If you do not have air conditioning, contact your local health department or locate an air-conditioned shelter.
  2. Stay hydrated. Drink more water than you usually do, and don’t wait until you’re thirsty to drink. 
  3. Don’t use the oven or stove for cooking as it makes your house hotter. 
  4. Limit outdoor activities. 
  5. Wear and reapply sunscreen. 
  6. Wear loose, lightweight, light-colored clothing. 
  7. Take frequent cool showers or baths. 
  8. Never leave pets or children unattended in the car. 

Stay ahead of the intense heat by tracking local temperatures, humidity, and UV index in your TMRW Weather app. If you or someone you know is showing symptoms of a heat-related illness, seek medical care immediately. View symptoms of heat-related illnesses here
