 Starting out sticky again this Tuesday morning. Temperatures mostly in the 70s. For the third straight day, a heat alert's in effect for the afternoon. High temperatures near triple digits. The heat index 105 to 110. Isolated showers and thunderstorms late afternoon into the evening. Overnight were quiet upper 70s. Wednesday mid-90s for highs. A better chance for scattered showers and storms during the afternoon and evening. For the North Carolina News Network, I'm meteorologist Chris Michaels in the Weather Center.
