Coldest day since January

At 4 p.m., the official temperature at Philadelphia International Airport reached 27, making it the lowest daily maximum temperature since Jan. 30. 

The winds gusting past 30 m.p.h. gave the air an icy bite, and at 9 a.m., the wind-chill reading was +2 Fahrenheit. The wind-chills stayed in the teens all afternoon.

Last winter was historically snowy, as we all know, but it wasn't particularly cold. February finished 3 degrees below normal, and the December-January period came in about a degree below.

The consensus among forecasters is that snow this winter will be closer to the long-term average, around 20 inches, or perhaps less.

However, the snow threat for the weekend is still alive. The U.S. model has been bullish on a major snowstorm on Sunday, but it remains what the National Weather Service office in Mount Holly calls an "outlier."

The weather service dropped the mention of weekend precipitation in its morning package, but put it back in the afternoon. The European model wants to kick the snow out to sea.

We cannot emphasize enough that it's only Tuesday. Our advice is to treat this like an NBA game; it gets serious late in the fourth period.
