An excessive heat warning continues until Saturday evening, as daytime high temperatures in the mid-to-upper 90s are expected, with heat index values as hot as 110 degrees likely in the afternoon and evening hours. Meteorologist Kurt Kotenburg with the National Weather Service reminds all residents that heat exhaustion is likely in these conditions with prolonged exposure outdoors.
