Some light rain and fog will greet Philadelphia this morning. Temperatures across the region will start off mainly in the 40s and 50s.
But as the day goes on, expect record warmth, with highs climbing into the upper 60s and 70 degrees in the city (the record is 64).
On Monday, it will be mostly cloudy and much colder Monday, with highs in the mid to upper 40s.
There's potential for some rain/sleet and maybe even freezing rain late Monday into early Tuesday. The better chance for this will be in the Poconos and parts of the Lehigh Valley. Otherwise, it'll be milder than Monday, with highs in the mid 50s.
