You know what's funny about hot and humid conditions for a meteorologist? The same people that complained about the cold, complain about the heat yet this is exactly what they asked for back in January! Oh well.

Today is the hottest day of the week with temperatures climbing rapidly into the lower to mid 90's along the New Jersey coast and mid 90's throughout the rest of New Jersey. There is even a threat for temperatures peaking in the upper 90's in the Delaware River Valley with enough sun shine. Of course, with all this heat and humidity, there is an isolated threat for a strong to severe thunderstorm this afternoon and evening. These thunderstorms will be capable of very heavy downpours, frequent lightning, wind gusts over 50 mph, and hail. The greatest concern with these thunderstorms, although isolated, will be localized flash flooding and wind damage. Winds will be from the southwest at 5 to 10 mph.

Tonight, a cold front over the Great Lakes and New England will slowly start to sink south. Clouds will increase with widely scattered showers and thunderstorms becoming more widespread towards morning. The strongest thunderstorms will again feature very heavy downpours, frequent lightning, hail, and wind gusts over 50 mph. Winds will remain from the southwest at 5 to 15 mph. Temperatures will fall into the upper 60's to lower 70's throughout the state, mid 70's in urban areas for lows.

The cold front by tomorrow morning will stall be north of New Jersey, however while a southwesterly wind will be in place at 5 to 15 mph, temperatures will not be as hot due to more cloud cover and a threat for showers and thunderstorms. Temperatures will rise into the mid to upper 80's along the immediate coast and upper 80's to lower 90's throughout the rest of New Jersey. Not everyone will have thunderstorms, but those that do will experience strong to severe thunderstorms capable of very heavy downpours, wind gusts over 50 mph, hail, and frequent lightning.

Tomorrow night, the cold front will finally drive through New Jersey with additional showers and strong thunderstorms. Winds will veer to the north at 5 to 15 mph. Temperatures will fall off significantly behind the cold front with lows in the upper 50's to lower 60's.

On Friday, a marine air mass will begin to build into New Jersey and replace the new Polar modified air mass that drove in from the previous night. Scattered clouds can be expected with an isolated shower possible but not likely. Winds will veer to the north and northeast at 5 to 15 mph. Temperatures will rise into the lower to mid 80's for highs.

A marine air mass will lock in over New Jersey by Saturday morning and remain in place through Tuesday. This marine air mass will feature scattered to overcast cloud cover with a threat of an isolated to widely scattered shower. Most locations will remain dry though. The best potential for showers will be over southern New Jersey near the back door cold front, which will be just south of Cape May, New Jersey through the period. With winds from the northeast at 5 to 15 mph, temperatures will struggle to reach near normal levels. Low temperatures will range from the upper 50's to lower 60's. High temperatures will range from the mid to upper 70's along the coast and upper 70's to lower 80's over much of New Jersey. Lower to mid 80's will be possible in the Delaware River Valley near Philadelphia.

So this stretch of hot and humid weather won't last much longer and what follows is another stretch of cool, at times raw, weather conditions. A gift from our friends in the Canadian Maritime.
