Get ready, New Jersey — this weekend is serving up a preview of summer, but not the sunny beach kind. Instead, we’re in for warm, humid air and an extended stretch of unsettled weather that brings a mix of sunshine, strong breezes, and frequent rounds of thunderstorms. It’s a classic case of spring clashing with summer, and the atmosphere is showing it.
What’s Driving the Weather?
An upper-level low pressure system — the kind that tends to linger — will get stuck just to the west of the Garden State. Thanks to a dominant ridge of high pressure stretching from Southeast Canada across Maine and out into the Atlantic, this storm system isn’t going anywhere fast. Expect it to slowly spin its way eastward across New Jersey over the next 5 to 6 days.
This weekend, that low stays just west of us, pumping in warm, moist air from the south. That means elevated temperatures, sticky humidity, and a good chance for thunderstorms — especially in the afternoons and evenings. Looking ahead to next week, the low finally begins to drift east by Thursday, bringing cooler temperatures but keeping skies cloudy and showery. While it may put a damper on outdoor plans, this prolonged rain is much-needed for gardens, reservoirs, and fire risk reduction.
Daily Forecast Breakdown
🌡️ Friday, May 2:
Temperatures will soar into the 80s across most of the state, and areas in West Central and Southwest New Jersey could flirt with 90°F. Coastal regions like Eastern Central and Southeast NJ will be slightly cooler but still pleasant in the 70s. Expect mostly sunny skies early on, but don’t let that fool you — increasing humidity will fuel scattered thunderstorms later in the day and into the evening. Winds out of the southwest will be gusty, so keep an eye on loose outdoor items. Overnight lows dip into the 55–65°F range with continued chances of overnight thunderstorms.
⛈️ Saturday, May 3:
Another warm one. Highs reach the 80s once again, especially away from the coast. The day will bring a mix of sun and clouds, but more scattered showers and storms are likely to pop up — particularly in the afternoon hours. South-southwest winds will stay breezy. Overnight lows will settle into the low 60s, and you can expect more thunderstorm activity heading into Sunday morning.
🌧️ Sunday, May 4:
Sunday starts to cool down a bit, with highs in the low to mid 70s across the state. Skies will be mostly cloudy with on-and-off rain expected throughout the day — and don’t rule out a rumble of thunder, especially later in the day. While it won’t be a washout, outdoor plans will need some flexibility. Breezy southern winds persist, and Sunday night will stay mild near 60°F with periods of rain continuing into Monday morning.
Looking Ahead: May 5–9
The warm, stormy pattern transitions into a cooler, rainier stretch next week. Expect daytime highs to fall into the upper 60s and lower 70s, with daily chances of rain and spotty thunderstorms. While the thunderstorm risk won’t be as high as the weekend, don’t put away the rain gear just yet. We may not see clearing skies until Thursday.
Rainy Days, But Silver Linings
Yes, this stretch of wet weather may put a dent in your weekend hiking, beach, or barbecue plans — but it also brings relief after a dry start to spring. It’s a great time to catch up on indoor projects, visit museums or coffee shops, and plan a cozy movie night.
