TODAY: It's mostly cloudy with flurries at times. The high is 38 around noon. Then, winds build and temperatures plunge into the 20s by evening.

TONIGHT: Skies clear, but it remains very windy with temperatures continuing to plunge. Evening numbers in the 20s give way to an overnight low of 11 in Philadelphia with many suburbs dipping into the single digits. Wind chills will drop below zero. A WIND CHILL ADVISORY is in effect for Saturday morning in the Poconos, where it could feel as cold as -20 at times!

SATURDAY: It's sunny, but brisk and much colder. The morning low: 11. The afternoon high: 26.

SUNDAY: The sunrise temperature is around 19. We start out with sun and then turn to clouds. By evening, snow moves in, thanks to a storm system passing by us to our south. This is not a nor'easter, as the storm center will likely move straight off the Virginia coast, rather than cut north along our coastline. But it will have enough moisture and feature enough cold air to produce snow for us, north of the storm's central low. It will likely begin snowing during the Superbowl with as much as an inch or two on the ground in some areas by the time the game ends. You might want to think about limiting travel or not going too far if you're gathering somewhere away from home to watch the game. Sunday's high: 36.

MONDAY: It will very likely be snowing during the morning commute, creating slow, slippery travel conditions. The snow likely tapers off later in the morning or afternoon. The high is 30.

SNOWFALL: How much snow we get Sunday night into Monday depends upon the track of the storm, as well as how much warm air can potentially make it up into our area as the low approaches. Will the warm air be overwhelmed by the cold air already in place here, keeping us in the storm's central snow band? Or does warm air mix in, changing some of our potential snow into rain instead? Or will the storm track shift farther south, taking us out of the higher snow zone? All good questions. It does look as though at least some snow begins to fall between 5 and 7 p.m. Sunday evening and continues until around noon on Monday. A total snowfall of 3-6" seems reasonable with less in the far south and more to the north. But this is a very preliminary estimate and it would be a good idea to check out forecast updates, especially over the weekend with my team, my friends, Melissa Magee and Chris Sowers.

TUESDAY: It's sharply colder with plenty of sunshine, but a strong wind and cold air counteracting the sun's potential warming effect. The high is only 24.

WEDNESDAY: It's not as harsh in the afternoon. Sun mixes with additional clouds. The high: 37

THURSDAY: It's mostly cloudy with a chance or rain or snow. The high is 35.

FRIDAY: It's brisk and coder again with partly sunny skies and a high of only 26.
