 A mild and muggy start to our Monday morning with another day of heat alerts in effect. Make sure you're staying hydrated early and often on this Monday. High temperatures 98 to 100. The heat index 105 to 110. Isolated showers and storms possible this afternoon. Upper 70s for lows tonight. Then by Tuesday, we're back at it with 98 to 100 degree heat and more isolated storms. For the North Carolina News Network, I'm meteorologist Chris Michaels in the weather centers.
