Discussion: The center of the approaching system is actually in SE Canada which is producing a large mid-latitude cyclone for much of E North America. For NJ, we’ll see the southern side of it in the form of a cold front with low pressure riding the cold front. Our low is just getting started near Florida and will track up the coast between now (Wednesday PM) and Friday AM.
The low will bring periods of moderate-to-heavy rain between tonight (Wednesday) and tomorrow night (Thursday). Here’s what the high-res NAM is spitting out for total rainfall in inches ending late Thursday night:
No other significant concerns with this one (wind or coastal flooding). Just some flash flooding to watch out for (better probability) and possibly some embedded thunderstorm action (lower probability). The system then clears out with temps dropping Thursday night into Friday morning. A very transient colder period sets up for all of Friday into about Saturday morning. Then temps moderate for a drier and milder weekend.
In English: Rain is approaching and should gradually fill in from W to E this evening into overnight hours. Rain should then fall, moderate-to-heavy at times, through late Thursday PM. Conditions then clear and turn colder for Friday into Saturday morning. The rest of Saturday and Sunday look nicer which I’ll cover more in the weekend outlook tomorrow. For now, get ready for another soaker tonight through tomorrow night. Be safe! JC
