A large high pressure system aloft near the Four-State Region will provide very hot temperatures eclipsing the triple digits. This heat will combine with the relative humidity, resulting heat index values at or above 110 degrees during the peak heating times from late morning through early evening. These dangerously hot temperatures will continue through the weekend with additional warnings expected to be issued.
Heat stress conditions will be increasing over the next several days as temperatures climb well into the triple digits. When combined with the humidity, heat index values will approach or exceed 110 degrees. Take the necessary precautions to protect yourself during these dangerously hot conditions. Drink plenty of water, stay inside as much as possible in an air-conditioned environment, and limit outdoor activity to early morning or evening with frequent breaks in the shade. Please remember to check on those most susceptible to the heat including the elderly, young children, and pets!
Heat illness is a serious condition that can occur quickly in times of excessive heat and humidity. Heat stress conditions will be increasing over the next several days as temperatures climb well into the triple digits. When combined with the humidity, heat index values will approach or exceed 110 degrees. Know the signs of heat illness and the difference between heat exhaustion and heat stroke. Heat stroke is a potentially deadly condition that requires immediate medical attention. Call 9-1-1 immediately if you suspect heat stroke!
