Serious heat, humidity arrive Wednesday, sparking potential heat wave

While the high humidity arrived on Tuesday, the full blast of heat arrives on Wednesday. Excessive Heat Warnings have been issued for the day in New Jersey as the heat index will approach 105 degrees. For the city, a Heat Advisory has been issued, but that will get upgraded by Thursday to an Excessive Heat Warning. Temperatures on Wednesday will soar to around 90 degrees in the afternoon. However, adding in the heat and humidity, it will feel more like around 100 degrees in the city. Portions of New Jersey away from the coast may end up feeling more like 105 degrees. All that heat and humidity could spark an isolated shower and thunderstorm starting in the afternoon and the threat lingers into the evening.
