Raleigh, N.C. — Thursday's extreme heat is just the beginning for the Triangle, WRAL meteorologist Mike Maze said. Fifty North Carolina counties are under a heat advisory and there is no relief in sight.

“We could have this extreme heat through the mid part of June,” Maze said. "But, we’ll take it day by day before we get overwhelmed."

The weekend was forecast to be even hotter, with Friday, Saturday and Sunday highs estimated at 99 degrees. Even in shaded areas, the heat will feel like 105 degrees.

“If we do, by chance, reach 100 degrees, this will be the earliest in any year that we have seen a 100-degree reading at (Raleigh-Durham International Airport),” Maze pointed out.

WRAL Chief Meteorologist Greg Fishel said to expect days in the high 90s and sultry nights cooling only into the mid 70s into next week. The extreme temperatures could last until June 15 or 16.

Fishel urged viewers to "play it safe" and not overexert themselves in this heat.

Even the governor got into the act, issuing a statement urging citizens to take precautions against heat stroke.

The state departments of Health and Public Safety suggest these tips for keeping cool:

• Do not leave children or animals in a parked car, even for just a few minutes.
• Drink plenty of fluids, preferably water, especially if you must spend time outside.
• Wear lightweight, light-colored, loose-fitting clothing.
• Use sunscreen, sunglasses and a wide-brimmed hat to protect from sunburn.
• Stay indoors in air-conditioning if possible.
• Take a cool shower or bath.
• Avoid cooking with the stove and oven.
