Heat wave grips New Jersey

The National Weather Service issued a hazardous weather outlook, an excessive heat warning and a flash flood watch for New Jersey, extending into Monday night.

Heat index values will be around 105 to 110 on Sunday afternoon, or a bit lower in the elevated terrain of the Poconos and far northern New Jersey, as well as right along the coast.

Temperatures will be in the mid to upper 90s this afternoon. The most dangerous of the heat and humidity will occur from mid afternoon into the early evening Sunday.

The heat and humidity may cause heat stress during outdoor exertion or extended exposure. The most susceptible individuals are the elderly and those with pre-existing health issues.

The oppressive and dangerous heat wave gripping much of the Midwest to Eastern U.S. will give way after a cold front passes on Monday and Tuesday, bringing with it a risk of severe thunderstorms.

In the meantime, Excessive Heat Warning and Heat Advisory extend from parts of the Central/Southern Plains eastward to the Ohio Valley with a second area from parts of New England southward to the Southern Mid-Atlantic.

On Sunday, the greatest heat threat will be from the Carolinas to Maine where daytime highs in the mid to upper 90s combined with high dewpoints will make it feel like its near 100 to 110 for many.

Even overnight will provide little relief as temperatures struggle to get below the upper 70s or even low 80s.

This may challenge or break daily record high minimums for a large number of stations across the Ohio Valley/Northeast and Mid-Atlantic.

See www.weather.gov for the latest on the coverage of warnings, and also tips on how to stay safe in this heat.

The dangerous heat wave will continue through Sunday, with showers and thunderstorms forecast to bring periods of heavy rain.

A front extending from the Lower Great Lakes roughly westward to the Central High Plains will move southward to Northern Mid-Atlantic southwestward to Central Texas Monday evening.

The front will bring an end to the heat wave over the eastern two thirds of the country by Monday evening. Showers and thunderstorms and cooler temperatures will accompany the boundary over the Central Plains and Midwest on Sunday. Some storms could be severe across Middle Mississippi Valley and Central Plains.

Locally heavy rainfall could lead to flash flooding as well as the front progresses slowly south and eastward, reaching the East Coast by Monday.
