Enjoy warmup before deep freeze?

Posted: January 08, 2013

No snow is in the 10-day forecast, but there could be some rain, as the region is beginning a stretch of warmer days.

Enjoy it while it lasts.

AccuWeather warns that in a week or two "brutal cold waves" could be forced down from arctic regions.

That could even mean "a series of storms" as the cold moves toward the south and east, according to meteorologist Jack Boston.

Although high pressure off the Atlantic coast may ward off the worst for a while, "most of the time in situations like this, cold air finishes the job and reaches the Atlantic Seaboard," says meteorologist Joe Lundberg.

Back to this week's good news:

Sunday's high of 48 was the warmest temperature in Philadelphia since Dec. 21, and expect highs at least that high into the weekend.

Saturday and Sunday could reach the relatively balmy mid to upper 50s, according to the National Weather Service and Weather.com.

For a few nights, lows could continue to flirt with the freezing mark in the city, before moderating into the mid 30s Thursday night and low 40s Friday and Saturday nights.

Rain is likeliest Thursday night and Friday, with a 50 to 60 percent chance.

Next Monday, the range seems likely to be more normal again, with highs in the 40s and lows in the low 30s.

Stay tuned for more on the possible big chill after that.
