The work week will start off with a new round of heat and humidity as high temperatures climb back in the low to mid 90s. The hot conditions peak on Tuesday with widespread heat index values at or above 100, followed by a brief cool down Wednesday, before more heat is favored to end the work week. Those who have to be outside should take appropriate safety precautions to avoid heat-related illnesses, including drinking plenty of water, taking frequent breaks in air conditioning, and wearing loose, light-colored clothing. Never leave pets or children in vehicles unattended for any amount of time.
