It won’t be the worst day for outdoor activities as a strengthening low-pressure system moves through. However, future activities this weekend will likely require a winter jacket.
Clouds continue to build and thicken Friday morning as high pressure retreats into eastern Canada. Winds will be enough to bring spotty areas of minor coastal flooding during the a.m. high tide. Move your cars if you need to and be prepared for water on the first block of bay side roads (don’t drive through standing water!).
Otherwise, I believe Friday during the day will not be a washout.
There is a big slot of dry air about 3,000 to 6,000 feet above our heads. This will keep the rain at the proverbial door for most of the day. Showers will be more miss than hit. If you have outdoor plans, I would keep them, unless they are extremely sensitive to rain. High temperatures will be around 60, blowing in the mild ocean water.
After dark will be a different story.
The center of the low-pressure system (our double-barreled low) will start periods of rain during the p.m. commute, between 4 and 7 p.m. You will need the rain gear heading out Friday evening.
This will end between midnight and 3 a.m. Rainfall totals of a half inch to an inch will be expected.
As soon as the rain ends, winter moves in. A powerful northwest wind will blow from late Friday night into most of the day Saturday. This will clear us out and dry us up in a hurry, but tap into our first true arctic shot of air. We will have plenty of sun Saturday, but highs will be around 50 degrees. That’s not bad, but once the winds calm, temperatures will drop like a rock.
Sunday morning lows will be in the mid 20s on the mainland. The shore will hold in the mid 30s.
Sunday will then have a high of 47 degrees just about everywhere. That will be the coldest day since April 17 across South Jersey. Even with plenty of bright sun and a calm wind, it will feel more like mid February than mid November.
