Philadelphia residents are waking up to bitter cold this morning, and forecasters say to expect more of the same through the rest of the week.

High temperatures for the week are expected to only hit the mid- to upper-20s, said Dean Iovino, a meteorologist with the National Weather Service. And lows should fall into the teens.

"It's going to be colder than it's been in quite a while," Iovino said.

Colder than it's been in two years, in fact.

The last time Philadelphia experienced a similar cold stretch was exactly two years ago: Jan. 22 through Jan. 24, 2011, when high temperatures of 24, 27 and 25 degrees were recorded, according to the weather service.

But Iovino said these temperatures aren't terribly unusual for January, and we shouldn't come close to the record low temperatures. Those bitter-cold temperatures are -7 degrees for today, -2 degrees for Wednesday, zero degrees for Thursday and -2 degrees for Friday.

Most places in the Philly area saw a half-inch to an inch and a half of snow Monday evening into early this morning, with 1.4 inches at Philadelphia International Airport. Forecasters say no more precipitation is expected until Friday, when light snow or wintry mix is expected.

"It could be a little messy," Iovino said.

The cold front is already affecting commuters: SEPTA said A and B service on the Market-Frankford Line is cancelled due to the cold; all trains are making local stops.
