Much higher temperatures are on the way to Philadelphia. The warmth will be accompanied by spotty rain and patchy fog at times.
Record-challenging warmth is possible on Sunday with temperatures surging close to 70 degrees.
As warmer, more moist air moves in, episodes of fog are possible which could slow travel.
Heavy rain will stay north and west of Philadelphia through the day Sunday.
According to AccuWeather.com Long Range Expert Paul Pastelok, "With the anticipated weather now through the end of the month, temperatures for December may average close to normal."
As of Dec. 18, temperatures have averaged 2.5 degrees below the normal of 39.3 degrees for the month to date.
Pastelok expects the weather pattern to erase much of this local temperature deficit by the end of the month with well above-average warmth forecast late this week into the weekend.
"There will still be a few chilly episodes later in the month, but not to the extreme of what we have experienced during late November into early December," Pastelok stated.
The warmup will not mean an end to snowstorms for the upcoming winter.
