Heat, humidity building; severe thunderstorms possible Tuesday, Wednesday

Heat and humidity will peak on Tuesday, possibly sparking thunderstorms Tuesday and Wednesday, forecasters say. 

“Tuesday looks like to be the warmest day of the next week for the vast majority of the region,” the National Weather Service advises in a forecast discussion. Heat index values will range from the middle to upper 90s for the coastal plain.

Some of the thunderstorms could be severe, according to the service. 

The primary hazard Tuesday is expected to be strong winds, while marginally severe hail and brief heavy rain are both also possible. Forecasters say the highest threat of severe weather on Tuesday will be along and northwest of the Interstate 95 corridor. 

By Wednesday, the greatest threat for severe weather will be in southeastern New Jersey as a cold front passes through the area, leading to more comfortable and somewhat cooler weather on Thursday.
