Barely an hour into Dec. 15, a record-high temperature for the date had already been set.

The 69 degrees recorded at Philadelphia International Airport at 1:14 a.m. Tuesday bested the previous record of 66 degrees, marking the fourth-consecutive day Philadelphia has set a daily temperature record.

The old mark had been set in 2008 and 1971.

The National Weather Service said several places in the Philadelphia region also hit record temperatures Tuesday shortly after midnight, ahead of an expected cold front.

Other locations with new records include Trenton at 67 degrees, Allentown at 66 and Wilmington at 68.

Philadelphia also saw record highs on Saturday (69 degrees), Sunday (71 degrees) and Monday (70 degrees).

More records could be on the way later this month, as some meteorologists, including NBC10's Glenn "Hurricane" Schwartz, say temperatures could again reach into the 60s for Christmas Eve and Christmas day.
