The calendar says it’s October, but the normally crisp autumn air is going to feel more like a summertime scorcher by the middle of this week, with temperatures making a run for 90 degrees on Wednesday.
Some old records could be broken, too.
An abbreviated heat wave is on the way thanks to a surge of warm air flowing in from the south. But it’s going to last just one day.
After that, forecasters say, a cold front will move in and the mercury will take a big dive into the upper 60s — right around where it should be this time of year in the New Jersey region.
Our weather roller coaster ride actually started on Monday, with temperatures hovering in the upper 60s to low 70s in the northern half of the state and mid-70s in the southern region. They will likely climb to around 80 degrees on Tuesday, then shoot up near 90 on Wednesday.
Adding to the summer-like feel will be rising humidity and a chance of showers and thunderstorms Wednesday afternoon, Wednesday night and again on Thursday, when temperatures will cool down.
It should actually feel like autumn this weekend, with daytime temperatures in the 60s to low 70s and overnight lows dipping down into the chilly 40s. Weekend lows could get as cold as the low 40s in North Jersey and mid-40s in Central Jersey, while hovering in the upper 40s in South Jersey.
Crisp autumn air — the way it’s supposed to be.
