Central And Southwestern U.S. Contend With Dangerous Heat

Heat and humidity remain in place across the central U.S. while the mercury creeps higher across the Southwest.

High pressure will shift west this week, strengthening over the Four Corners states. As it does this, temperatures across the southwestern U.S. will reach dangerous levels.

High temperatures will range between the middle 90s and lower 100s across the central and southern Plains into the Middle and Lower Mississippi Valley. These temperatures combined with high humidity will make it feel even hotter. Heat index values will soar to as high as 105 to 110 degrees!

Widespread Heat Advisories are in place across most of Arkansas, southeastern Oklahoma, northeastern Texas, parts of Louisiana and into Mississippi.

Parts of the Southwest including southern and western Arizona, southern Nevada, and parts of southern California are under an Extreme Heat Warning starting on Wednesday as the heat builds in. Heat Advisories are also in place across California and the rest of the Desert Southwest, with a Heat Advisory also in effect across eastern Montana and western North Dakota.

We might start to see some record high temperatures in jeopardy today and Thursday as this ridge of high pressure shifts west. Nineties will be felt as far north as Idaho and western Montana, while numerous spots along and west of the Rockies will see the mercury climb into triple digit ranges. The Desert Southwest could even report temperatures as high as 115 degrees!

If you must go outdoors, prepare by staying hydrated and keep a watchful eye for any signs of heat-related illnesses such as heat stroke and heat exhaustion. Wear the right clothing, such as loose-fitting, lightweight and breathable fabrics, and take many breaks within a cool and shaded area.

Make sure to take extra precautions for children and the elderly as they are more susceptible to heat-related illness. Never leave children or animals alone in a locked vehicle as it can become dangerous and potentially fatal.
