president obama's time in office. >> christa: the air is bitter cold. >> sarah: so cold. it was like piercing on my skin. >> chris: you think today is bad, wait until this weekend. you can probably knock off another 20 degrees on the temperature and wind-chill factor for many towns. we're talking about dangerous cold by sunday morning, in fact, a wind-chill warning in effect in this light shading of blue essentially from interior southeastern mass out through worcester county into outer route 2, including the city of boston. a wind-chill factor 20 to 30 degrees below zero coming in here saturday night into sunday morning. no shortage of cold air across hudson bay. this is directly going right down into new england. now, it won't be 30 below temperature-wise, but it doesn't modify all this much as we expect temperatures by sunday morning to be in the minus 5 to minus 10 range west of the city of boston. even boston a couple degrees below zero and close to zero down across the cape. we'll have bitter wind-chills as

taking a look at temperatures outside now. today's in slouch in terms of cold weather. 8 degrees in the city of boston. 0 in worcester. 1 in jaffrey, new hampshire. those are the air temperatures. you factor in the wind, which is blowing right now out of the west at about 14mph in the city of boston, and the wind-chill factors this morning are indeed below zero, minus 8 in boston, minus 14 in worcester and again the wind-chill values by sunday morning are going to feel about 20 degrees colder than what it feels outside this morning. so getting the kiddos ready for school, definitely need the winter gear and probably an indoor reset today as we only top off in the upper teens and lower 20s by lunchtime and then rise up to about 22 degrees as we work into the afternoon. so we have a lot of cold air ahead of us. what about any snow? looks like we could get a little snow breaking out overnight tonight say past 9:00, 10:00, southeastern mass. the best chance to pick up on a couple inches of snow will be the cape and the islandses from
