Oppressive heat and humidity will combine to make it feel like 103 degrees in the region that includes the Greater Red Bank Green starting Wednesday afternoon, according to the National Weather Service. 

The so-called heat index, a blend of air temperature and humidity, will rise several degrees Thursday, with conditions worst in the afternoon and “little relief at night,” the agency’s Mount Holly office said on Twitter early Wednesday. An excessive heat warning for western Monmouth County has now been extended to Friday night.
