A brutal heat wave will begin this weekend in the Southwest, with temperatures well exceeding 100 degrees in many spots.
Because the intense heat could last for several days, the National Weather Service (NWS) has issued excessive heat warnings across the region, including southern Nevada, southern California and a large portion of Arizona.
High temperatures will range from 105 to 115 degrees, but may gradually approach 120 in localized areas next week. While triple-digit heat isn’t unusual in early to mid-June, these highs will be above normal. Some daily records may be tied or broken in places like Las Vegas; Phoenix, Tucson and Lake Havasu City, Arizona; as well as El Centro, Riverside, Palm Springs and Death Valley, California.
To stay cool, drivers should wear loose-fitting, light-colored clothes and bring extra bottled water with them. Make sure trucks are in tip-top shape and stay in air-conditioned spaces when taking breaks. Also, be sure reefer trailers are in good condition to ensure temperature-sensitive freight doesn’t get damaged.
Dangerous heat will also hit the Plains Friday. High temperatures and heat index values will exceed 100 degrees from Tulsa and Oklahoma City, Oklahoma, to Wichita Falls, Abilene and Midland-Odessa, Texas, as well as Roswell, New Mexico.
