With hazy, hot, and humid conditions in place this afternoon, a cold front will bring a threat for isolated showers and thunderstorms to New Jersey this evening. This cold front will put a rapid end to the hot and humid conditions by tomorrow afternoon, but the heat and humidity will return for the second half of the Labor Day weekend.

This afternoon, clear skies to scattered cloud cover can be expected throughout New Jersey. Winds will be from the southwest at 5 to 10 mph, increasing to 5 to 15 mph by this evening. Temperatures will rise into the mid 80's along the immediate coast and upper 80's to lower 90's throughout the rest of New Jersey, especially in urban locations. The combination of these temperatures with high levels of humidity will lead to a heat index in the mid 90's.

A cold front will move through New Jersey this evening through tomorrow morning with widely scattered to isolated showers and thunderstorms. The strongest thunderstorms will be capable of wind gusts over 40 mph, hail, heavy downpours, and frequent lightning. Most locations however will remain dry this evening. Winds will veer from the southwest to northwest at 5 to 15 mph. Temperatures will fall into the lower to mid 60's for lows.

Tomorrow, the cold front will clear the coast with clearing skies by the late morning and early afternoon hours. Winds will be from the northwest at 5 to 15 mph. Dew points will crash through the 60's and into the upper 40's to lower 50's by evening leading to much more pleasant weather conditions. Temperatures will rise into the upper 70's to lower 80's for highs.

High pressure will be in control tomorrow night on through Saturday with clear skies to scattered cloud cover expected. Winds will become light and variable. Temperatures on Friday morning will range from the lower to mid 50's over northwester New Jersey and mid to upper 50's along the coast. High temperatures on Friday will rise into the upper 70's to lower 80's throughout New Jersey. Temperatures on Saturday will range from the upper 50's to lower 60's for lows and lower to mid 80's for highs.

High pressure will shift to the east of New Jersey on Sunday with increasing clouds and winds from the southwest at 5 to 15 mph. Fog will be a threat in the morning hours followed by muggy weather conditions in the afternoon. Temperatures will range from the mid to upper 60's for lows and mid to upper 80's for highs.

A cold front will approach on Monday, Labor Day, with increasing clouds through the day followed by scattered showers and thunderstorms in the late afternoon and evening. The strongest thunderstorms will be capable of very heavy downpours, frequent lightning, hail, and wind gusts over 40 mph. Most of New Jersey will remain dry through the afternoon. Temperatures will range from the upper 60's to lower 70's for lows and mid 80's along the coast and upper 80's to lower 90's throughout the rest of New Jersey for highs.

Skies will clear on Tuesday as high pressure builds into the region. Temperatures will range from the lower to mid 60's for lows and lower to mid 80's for highs.

Overall, much of the Labor Day weekend will be dry and very much Summer like. Perfect for out door activities and the shore.
