A Welcome Breath of Less Humid Air for New Jersey
A front has delivered somewhat cooler and much drier air to the Garden State, but the pleasant and more comfortable weather is only temporary.
The same front that spawned Monday afternoon's heavy thunderstorms will deliver a wonderful treat to New Jersey over the next 2 to 3 days. After almost a week of intolerable heat and humidity, drier air will cause humidity levels to drop sharply. That means it's about to become much more comfortable around the Garden State.
Dew point is a measure of moisture in the atmosphere, which is a much better indicator of atmospheric moisture and/or comfort than a relative humidity percentage. Tuesday morning's dew points are still near 70 for part of New Jersey - that's pretty steamy. But by midday Tuesday, dew points will drop into the 50s, and we might even see dew points in the 40s by the end of Tuesday. That's bone-dry air, and will be a stark difference from the past week of tropical air.
Despite the drop in humidity, it's still going to be quite warm across New Jersey on Tuesday, with high temperatures generally in the mid to upper 80s. 90 degrees is certainly not out of the question. A shower or thunderstorm is also possible, but only for far South Jersey (if at all).
Tuesday evening and Wednesday morning are going to be incredibly comfortable, as low temperatures dip into the upper 50s to lower 60s. The last time it was this cool? July 4th.
I have been describing Wednesday as the "weather winner of the week" and that description of the forecast still holds true. Sunshine and warm temperatures in the 80s will join the very low humidity to make for a gorgeous day. It might be nice enough to turn off the air conditioner and pop open the windows for a bit. Don't worry - Wednesday will stay dry. (And Thursday too.)
Wednesday night will again be pleasant and fairly cool, but don't get used to the low humidity. On Thursday, a wind shift will carry moisture back into New Jersey's atmosphere, causing the mugginess to slowly return. It should still be a nice day, although warmer with highs in the upper 80s, with mostly to partly sunny skies.
And then the heat and humidity return with a vengeance. High temperatures will climb well into the 90s on Friday... and Saturday... and Sunday... and Monday too! The weekend could indeed feature the hottest temperatures of the summer so far, and triple-digits are not out of the question. There will be a couple of chances for thunderstorms too - mainly Friday afternoon and Sunday night. But without a doubt, the big weather story will be the oppressive heat building throughout this last weekend of July.
