As an area of low pressure lift into the St. Lawrence River Valley through this morning, a strong mid level disturbance enhanced rainfall over southern and east-central New Jersey leading to very heavy rainfall and flash flooding. While the rainfall has now exited New Jersey, the influences from last night's rainfall will linger for some time.

Last night, a strong mid level disturbance developed over Maryland and tracked towards the New Jersey coastal waters and then Long Island. The strong disturbance enhanced lifting along the New Jersey coast leading to rainfall rates of one to three inches per hour. As a result, rainfall amounts ranged from three inches to as much as nine and a quarter inches of rain over southern and east-central New Jersey. Because of intense lifting along the coast, the rainfall was far less over northwestern New Jersey ranging from a quarter of an inch to an inch of rain.

The good news is that the heavy rain is now over as the occluded cold front has now cleared the New Jersey coast with clearing skies by this afternoon from west to east. Winds will be from the northwest at 10 to 20 mph, decreasing to 5 to 15 mph by this evening. Temperatures this afternoon will rise into the mid to upper 70's over northwestern New Jersey, upper 70's to lower 80's over central and eastern New Jersey, and lower to mid 80's over southern New Jersey.

High pressure will take hold tonight with scattered clouds to clear skies. Winds will be from the northwest at 5 to 15 mph. Temperatures will fall into the lower to mid 50's over northern New Jersey and mid to upper 50's along the New Jersey coast.

High pressure will be in control tomorrow on through Saturday with clear skies to scattered cloud cover. Winds will be from the northwest at 5 to 10 mph. Temperatures will average below normal through the period. Low temperatures will range from the lower to mid 50's over northern New Jersey and mid to upper 50's over the rest of New Jersey. High temperatures will rise into the lower to mid 70's over northwestern New Jersey and upper 70's to lower 80's throughout the rest of New Jersey.

On Sunday, the high pressure system will shift off the coast with clouds increasing through the day and winds backing to the southwest at 5 to 15 mph. Temperatures will range from the lower to mid 60's for lows and lower to mid 80's for highs.

A cold front will move through on Monday with scattered showers and thunderstorms. The thunderstorms will be capable of heavy downpours, frequent lightning, and wind gusts over 40 mph. Temperatures will range from the mid to upper 60's for lows and lower to mid 80's for highs.
