Forget about a warm finish to the month of April.
Saturday's blast of heat already moved out of New Jersey, pushed out by a cold front that will stick around for the day on Sunday, according to the National Weather Service.
A set of cold fronts moving through the region are responsible for the quick change in temperatures, which could also be accompanied by thunderstorms, according to AccuWeather.
Temperatures that reached the high 80s on Saturday will plummet to the 50s and possibly reach the 60s in some areas on the state on Sunday, the weather service says.
The day starts off with a slight chance of showers and thunderstorms before noon then remains mostly cloudy for the rest of the day. For northern New Jersey, temperatures could reach 60, but the Shore will be cooler, around 54, the weather service says.
That chance of showers moves in again on Sunday night, mainly between 10 p.m. and 2 a.m., the weather service says. That's followed by a chance of showers or drizzle and patchy fog. Otherwise, the night will be mostly cloudy with a low around 47 to the north and 52 at the Shore.
The rollercoaster ride of temperatures doesn't end there. When that cold front moves out on Monday, it sets up the day to be mostly sunny to the south and partly sunny to the north, the weather service says. Temperatures should climb to the mid 70s.
But as another cold front heads in, so does a chance of showers and thunderstorms after 5 p.m., according to the weather service.
