Highs between Friday & Saturday will probably vary by around 15-20 degrees. That's how much cooler the airmass will be for some of you! This won't be one of those cold air outbreaks that keeps you inside, but it will be a tough one compared to where we have been seeing.
As for snow chances this weekend... I have taken them out of play! It does look like we'll see some snow, but not until Monday. That shouldn't be much! Just keep the colder air in mind for the week heading into 2010!
Hope you all had a great Christmas! I am off next week... I will be right here at home so if there are big changes coming I'll post! I might drop by to offer a line or three!
