Raleigh, N.C. — The heat on Friday will back off slightly around the Triangle, but many counties to the east will still see a heat advisory.
Counties from Interstate 95 to the east will be in a heat advisory from noon to 8 p.m., when the heat index will climb to at least 105 degrees. The heat index to the west will make it into triple digits but won't trigger an advisory.
"Dew points are a little lower as you head west," said WRAL meteorologist Elizabeth Gardner. "So, 60s for Greensboro, Asheboro and Southern Pines, and 70 for Raleigh and Roxboro.
"Then the dew points go up here as you head eastward. That's where it's muggiest and that's the reason why we'll have that heat index there."
Dew points will be in the low- to mid-70s from Raleigh to the east but in the mid- to high-60s in points to the west.
Storms will hold off as a cold front sits to the north and west of North Carolina.
Cooler temperatures will breeze into the Triangle over the weekend and into next week, Gardner said. High temperatures in the low 90s will be just a few degrees above the normal high for this time of year. But with the cooler weathers comes a higher chance of storms.
