The Schuylkill Banks were a busy destination Wednesday as temperatures reached 82 degrees in Philadelphia.

Spring has sprung, at least in meteorological terms.

But will it last?

A record-high temperature was set Wednesday in Philadelphia as the mercury climbed to 82 degrees at 2:47 p.m. at Philadelphia International Airport, thrashing the previous record of 73 degrees for the date in 2000. The forecast high for Wednesday had been 77 degrees.

In addition to Philadelphia, temperature records were tied or set the previous records from 2000 in Atlantic City, Trenton, Allentown and Reading by 1 p.m., the National Weather Service said.

It was the earliest day in a calendary year with a reported temperature "greater than" 80, and the second-earliest 80-degree day. The temperature reached that mark on March 8, 2000, according to the weather service.

Records may fall again Thursday, which could be the warmest of day of the week – with temperatures again near 80. Record temperatures for March 10 were set in 2006 in Philadelphia, Trenton and Atlantic City (all 76 degrees), and Reading and Allentown (both 75).

The winter warmup is courtesy of a high pressure system anchored off the southeastern United States, which is expected to remain in place through Thursday. A cold front is expected to move through the area late Thursday night and Friday morning.

Friday's high looks to moderate, to around 67.

Federal meteorologists have reported that the winter season just ended was the hottest in U.S. records, thanks to the combination of El Nino and man-made global warming.

The average temperature for the Lower 48 from December through February — known as meteorological winter — was 36.8 degrees, 4.6 degrees above normal. It breaks the record set in 1999-2000.

Last month was the seventh warmest February. National Oceanic and Atmospheric Administration climate scientist Jake Crouch said a super-hot December pushed the winter to record territory. The fall of 2015 also was a U.S. record.

Records date to 1895.
