The Bottom Line A strong cold front will spark some turbulent, active weather across all of New Jersey on Wednesday. A line of thunderstorms will roll in (and exit) quickly in the afternoon. And then a brisk wind will cause temperatures to take a big tumble Wednesday night. We’re looking ahead to roller coaster temperatures. Our next rain chance will arrive this weekend. Wednesday Runaway warmth and bright sunshine made Tuesday a spectacular spring day. Wednesday will start off fine. But Wednesday afternoon and Wednesday night, not so much. We’re waking up to temperatures primarily in the 50s. As clouds increase Wednesday morning, thermometers will push toward a high around the mid 60s. So far so good.
