Discussion: We’ll see some of the coolest air of the late-year so far this weekend. Complete high pressure dominance from Friday PM well into next week. This means lower temperatures and comfortable humidity levels. I wouldn’t be surprised to see at least NWNJ, and possibly more of NJ, dip into the 30s for these next few nights. The rest of NJ…at least down into 40s. Only the immediate SENJ coast has a chance to hang near-50 during overnight hours. Daytime highs this weekend will struggle to escape the low-to-mid 60s. So regarding temperatures we’re very cool this weekend. After the Sally remnants pass by to our S tonight (Thursday) through tomorrow morning (Friday) we are dry and clear from Friday PM through at least Sunday night. Again, this weekend should be the hardest fall slappin yet. Let the pumpkin-spiced craziness begin. The atmosphere will NOT be waiting for the first day of fall next week to remind us of what’s coming. The tropics remain active but no current threats to NJ. The most we’ll see from any of the numerous named systems out there is some light fringe rain tonight into tomorrow morning from the NW side of Sally’s remnants. And that looks like a SNJ/SENJ thing only. Tonight (Thursday) seems like the last milder and relatively more humid night for a while.
Note: Unless specifically mentioned by location (Example: NNJ elevations, SENJ immediate coast, Interior CNJ/SNJ, etc.) assume the following forecast language is statewide for New Jersey. When I say “from elevations to sea” I mean from NWNJ mountains spreading down to SENJ coastal areas. Directions are shortened (N = North, S = South, W/SW = West/SouthWest, etc.).
Friday (Sept 18) high temperatures should reach the mid-to-upper 60s for most areas. Only extreme SENJ would likely reach or just break 70. Skies should cloudy and rainy (mostly for SNJ/SENJ) in the morning but improve by afternoon hours. Winds should be light out of the N. Overnight lows should range from near-40 to near-50 from elevations to sea. A steep drop in temperatures from day to night.
Saturday (Sept 19) high temperatures should fail to escape the 60s. Skies should be mixed with mostly sun and a few clouds. Winds should be light out of the N/NE. Overnight lows should again range from near-40 to near-50.
Sunday (Sept 20) high temperatures should again max out in the 60s. Skies should be mostly sunny. Winds should be light out of the NE for most, perhaps breezier along the immediate ECNJ/SENJ coasts. Overnight lows should range from upper-30s to lower-50s from elevations to sea.
An early look at the rest of next week indicates beautiful conditions. Highs in the 70s each day with plenty of sunshine. Overnight lows down into the 50s. Elevations colder. Immediate coasts a little warmer.
