With the advance of a warmfront this afternoon, the Philadelphia region will see a return of near spring-like temperatures - with even warmer weather ahead.
The National Weather Service is calling for fog before 10 a.m. today, followed by cloudy conditions through mid-morning. But then the skies should clear, bringing temperatures up to 62 and an overnight low of only 48.
The picture for Tuesday is even brighter. Partly sunny skies should dominate with a high of 65.
Then, temperatures should drop the rest of the week - but will still remain fairly warm for early December.
