The National Weather Service posted a heat advisory Monday for Chatham and Durham counties and everywhere east of them, warning that the day will feel like temperatures are in the range of 105 to 109 degrees.
Actual temperatures forecast to be in the mid 90s to upper 90s, combined with humidity, led to the advisory, forecasters said.
Above-average temperatures are in store for Tuesday, too, they said.
Slight relief Wednesday could come in the form of high temperatures that begin with an “8” instead of a “9.”
A Bermuda high-pressure system is holding the warm air over the state, the weather service said.
The system also explains why there is only a slight chance of thunderstorms forming. Humid air will have a hard time rising high enough to cool and form storms, forecasters said.
