Greensboro, NC -- All week most of the central United States have suffered under excessive heat and now it rolls east into the Triad.

An incredibly hot and large area of hot air will move east into the Triad on Friday and bring some of the hottest temperatures that the area has seen in five years. Triple digit heat will move out of the Midwest and Mississippi Valley on Friday and settle into the Southeast and Mid-Atlantic just in time for the weekend.

Temperatures Friday morning will start in the upper 60s, but quickly warm through the day under abundant sunshine. By midday temperatures will already be in the middle 90s before peaking near 100 degrees. The last time the Triad experienced 100 degree temperatures was in 2007.

The combination of the excessive heat and the humidity will send heat index values (apparent temperature) to between 102-105 Friday afternoon.

Conditions Friday night will not offer much relief as overnight lows only drop into the mid-upper 70s by early Saturday morning. By Saturday afternoon temperatures will rebound quickly once again and soar into the lower 100s.

The peak of the heat wave is expected to arrive on Saturday with heat index values between 105-107 in the Triad and even higher through eastern North Carolina.

While the hottest day is expected to be on Saturday the heat wave will continue through the weekend and into the beginning of next week. Triple digit readings could continue through Monday before temperatures cool into the mid-upper 90s for the middle of next week.

Consecutive days of excessive and dangerous heat has a cumulative affect on the human body. Heat of this magnitude and duration can trigger heat-related illnesses such as heat exhaustion or heat stroke. It is important that you, your family, friends, loved ones, and pets stay hydrated and protected from the heat over the next 5 days.

The best thing to do is to wear light weight loose fitting clothing, drink plenty of fluids and stay in an air-conditioned room if possible. If you work outdoors try to take frequent breaks and resist overexerting yourself. Your body has a much harder time recuperating in extreme heat situations.
