Philadelphians could wake up to a new record-low temperature on Tuesday.
The cold-for-May snap hitting the region today — temperatures are about 15 degrees below normal — should continue overnight, with a low temperature of around 41 degrees expected, the National Weather Service says.
If the mercury drops any lower than that, Philadelphia would have a new record: The coldest temperature ever recorded on May 14 is 40 degrees, according to the weather service.
The weather service is calling that mark a “possible vulnerable record low.”
