High pressure should have control of the region for the entire weekend. That means lots of sinking anti-cyclonic air which will inhibit showers and thunderstorms from forming in light of elevated temperatures and humidity. The only clouds I see forming are instability-driven cumulus which should fizzle out with loss of sun each evening. Sometimes these clouds can get large enough for an isolated tinkle or rumble but only a very small chance for that. Let’s break each day down:
Friday should have no problem reaching the mid-80s for afternoon high temperatures. Humidity should begin trickling in but not too bad. Skies should be mostly sunny with light S/SW winds. Overnight lows should drop into the 60s for most of New Jersey and maybe upper-50s in NNJ elevations.
Saturday should reach 90 in many locations. Only coastal regions should stay in the mid-to-upper 80s. Humidity should be noticeably elevated which should allow for heat indexes well into the 90s and possibly closer to 100. Skies should feature a mixed bag of mostly sun and a few clouds. Winds should be light out of the W/SW, a little more noticeable in SNJ than NNJ. Overnight lows should drop into the 60s statewide.
Sunday should also reach 90 in many locations and has a shot at reaching 95 for interior areas. Again, coastal regions might be held in the mid-to-upper 80s. Humidity should remain noticeably elevated which should allow for heat indexes closer to 100. Watch out for an isolated shower or thunderstorm if cumulus can build enough in the afternoon-early evening period. Most should remain rain-less. Winds should be light out of the W/SW, a little more noticeable in SNJ than NNJ. Overnight lows should drop into the 60s for most of New Jersey but maybe only the lower-70s along the coast (Finally, a reverse temperature buffer from the ocean = amazing feel for the coast).
An early look at next week indicates sustained warmer temperatures through at least mid-week along with the return of showers and storms.
