Heat Wave Grand Finale – Air Conditioning Will Be Your Friend
A Heat Advisory has been issued for part of New Jersey Tuesday, as widespread 90s and higher humidity levels will make for the most oppressive day of the week.
Here are your weather headlines for Tuesday, June 13, 2017...
The Heat Goes On
Monday was a record-breaker across the Garden State, as we hit daily high temperature records at Newark (old record: 95, new record: 97) and Atlantic City Airport (old record: 93, new record: 94). Trenton missed its record by a degree.
And Tuesday will make three. For the third day in a row, we have widespread 90+ degree temperatures in the forecast, making this an "official" heat wave. (Remember, the technical definition of a heat wave refers to an extended (72+ hour) period of heat and humidity, which can have significant impacts on both humans and the environment.) And it looks like this "grand finale" is going to be a doozy.
Tuesday's record highs are actually a few degrees higher than Monday (EWR 98, TTN 95, ACY 96). So Tuesday's high temps (88 to 97 degrees) are probably going to fall just short of records. However, with a slight uptick in atmospheric moisture (humidity) on Tuesday, it may feel more oppressive than the thermometer would suggest. Heat index ("feels like") temperatures are forecast to reach the mid to upper 90s for part of the state. Yuck.
A Heat Advisory has been issued for the New York and Philadelphia urban corridors through Tuesday evening. Once again, several NJ school districts have opted for early dismissals due to the heat.
Skies will be partly sunny and winds will blow out of the west-southwest up to about 15 mph.
Cold Front: Two Impacts for NJ
Yes, changes are ahead, with rain and a cooldown on the way!
A cold front will start to sag southward into New Jersey late Tuesday afternoon (after about 3 p.m.) That will potentially spark a few thunderstorms in North Jersey through the Tuesday evening rush hour.
A few more showers and thunderstorms are possible statewide Tuesday evening and Tuesday night. But models have really backed off the rain idea, so I really don't think everyone in NJ will get wet. Even with the raindrops and impending cooldown, Tuesday night and Wednesday morning will likely remain muggy with most low temperatures only dipping to around the 70 degree mark.
You'll definitely taste the cooler, drier air on Wednesday. No more 90s — high temps will be limited to around 80 degrees for inland New Jersey, and the mid 70s along the coast. With partly sunny skies and a refreshing breeze, it could actually be a nice, seasonable day.
Thursday gets even cooler, with statewide highs in the lower to mid 70s. That's 5 to 10 degrees below normal for mid-June. Again, I'll call it "refreshing" and potentially pretty pleasant (especially away from the coast).
Late Week/Weekend Forecast
The forecast turns complicated again starting Friday, as the aforementioned cold front flips around and pushes northward as a warm front. Again, we expect two impacts from this front — a warmup, and some rain.
A chance for showers and thunderstorms will begin Friday afternoon. And we have to keep scattered raindrops in the forecast through the weekend too, unfortunately. There should be dry periods at points on Saturday and early on Sunday. Steadier rain looks to arrive late-day Sunday.
Meanwhile, as the name implies, this warm front will cause temperatures to rise once again. Friday will probably get stuck in the lower 70s thanks to clouds and rain. But thermometers should bump back into the 80s on Saturday and especially Sunday.
