A powerful cold front is on the move and will slam into a tropical air mass that is locked in over New Jersey by this evening. This cold front will produce widespread showers and strong to severe thunderstorms this evening. However, tranquil weather conditions return for the end of this week and this weekend!
Hazy, hot, and humid weather conditions will be in place this afternoon throughout New Jersey. Winds will be from the southwest at 5 to 15 mph, increasing to 10 to 20 mph late this afternoon. A few isolated thunderstorms may develop this afternoon ahead of the main cold front, but most locations will remain dry yet uncomfortable. Temperatures will rise into the upper 80’s along the immediate coast, upper 80’s to lower 90’s over northwestern New Jersey, and lower to mid 90’s throughout the rest of the Garden State. These high temperatures in combination with the humidity will lead to a heat index in the mid 90’s to lower 100’s.
This evening through tonight, the first of two cold fronts will drive through New Jersey with showers and strong to severe thunderstorms. The thunderstorms will be capable of wind gusts over 60 mph, frequent lightning, very heavy downpours, and hail. An isolated tornado is possible, but not likely. Localized flash flooding, wind damage, and poor visibility can be expected with the most powerful thunderstorms. Winds will veer from the southwest to the west at 5 to 15 mph. Temperatures will fall into the lower to mid 70’s for lows.
A second cold front will follow tomorrow with widely scattered showers and thunderstorms expected through the day. Winds will veer from the west to northwest at 5 to 15 mph by the evening. High temperatures will range from the mid to upper 80’s along the coast and upper 80’s to lower 90’s throughout the rest of New Jersey.
High pressure will take hold by Thursday and remain in place through Sunday with scattered clouds to clear skies. Much lower humidity will be in place leading to range pleasant weather conditions. Low temperatures will range from the mid to upper 60’s throughout New Jersey, which is about normal for this time of year. High temperatures will range from the lower to mid 80’s along the coast and mid 80’s throughout the rest of New Jersey, which again is about average for this time of year.
A very strong cold front will approach the region on Monday with scattered showers and thunderstorms. Ahead of the cold front temperatures will range from the upper 60’s to lower 70’s for lows and upper 80’s to lower 90’s for highs. Behind the cold front a significantly cooler and less humidity air mass will take hold for the rest of the week and into the following weekend. Well below normal temperatures for this time of year are expected to take hold with the potential for highs only in the 70’s!
