Seasons seem to be less distinct in the greater Philadelphia area than ever before, with hints of just about every type of major weather pattern hitting the area over the past several weeks. The next dramatic shift up: spring and summer-like sun, forecasters said.

While Tuesday and Wednesday saw highs barely escape the 30s, the slight warming early Thursday is just the beginning.

“After a chilly start to the day, temperatures will moderate by this afternoon,” the National Weather Service’s Mt. Holly, New Jersey branch shared. “The warming trend will continue through the weekend.”

Highs will rise to 62 by Friday, 65 on Saturday, and all the way up to 70 in some parts of the region on Sunday, forecasters said.

Some light to moderate rainfall is possible in two main bursts: Friday night, with a 70 percent chance of showers and up to a quarter inch falling, and a lesser storm Sunday night into Monday morning.

Shifts in the jet stream are likely to continue to bring cold air down across the midwest and northeast over the coming weeks, according to Accuweather, interspersed with more warming periods.

“Additional back-and-forth swings between warm and chilly air will continue into April, especially across the Northeast,” Accuweather said.
