As high pressure over the St. Lawrence River Valley drifts east and low pressure continues to pass to the south of New Jersey, a marine air mass from the Atlantic Ocean will take hold leading to variable cloud cover and a slight risk for showers through this weekend.

While, heavy rainfall is not expected and most locations will remain dry, an increase in cloud cover can be expected through the forecast period as the marine air mass takes hold. A persistent easterly wind will also be observed which will keep temperatures cool along with a minor threat for some limited coastal flooding.

Today through tomorrow, clouds will slowly increase as high pressure drifts towards the coastal waters of Maine. Meanwhile, a series of weak low pressure systems will pass to the south of New Jersey keeping a threat for widely scattered showers in place over southern New Jersey and only an extremely isolated shower for northern New Jersey. Winds will veer from the north to the southeast at 5 to 10 mph. Temperatures this afternoon will rise into the upper 70's to lower 80's over much of New Jersey, mid 80's over southwestern New Jersey. Temperatures tonight will fall into the mid to upper 50's over northwestern New Jersey, upper 50's to lower 60's over northeastern New Jersey, and lower to mid 60's over central and southern New Jersey. High temperatures tomorrow will rebound into the lower to mid 80's over much of New Jersey, upper 70's to lower 80's along the immediate coast.

On Thursday, an area of low pressure will pass through southern New Jersey with widely scattered showers expected. The showers may produce a heavy downpour for a brief time. Winds will back from the southeast to northeast at 5 to 15 mph. Temperatures will range from the lower to mid 60's for lows and upper 70's to lower 80's for high throughout New Jersey.

High pressure over the Gulf of Maine will strengthen and build south leading to a complete invasion of marine air from the northwestern Atlantic on Friday. While scattered to overcast cloud cover can be expected Friday on through Monday, showers will be isolated at most through the period. Winds will remain from the east at 5 to 15 mph. Temperatures will range from the lower to mid 60's for lows and upper 70's to lower 80's for highs throughout New Jersey through the period.

Overall, the weather pattern will feature relatively tranquil conditions. While significant cloud cover can be expected, the threat for rain will be limited to only a few showers through the forecast period. Some locations may not see any rainfall at all through the entire forecast period in fact.
