Good Monday everyone and welcome to Christmas week. A lot of the region continues to dig out from this weekend’s big storm that caused all kinds of problems. Thousands remain without power and will do so for a while longer as crews work to get the juice up and running again.

This big week is starting off with a quick moving band of light snow and flurries as a weak clipper works southward across the area. This light snow won’t amount to more than an inch or so at most but can cause some slick spots to start the day. Here is your light snow tracking radar…



The rest of the forecast looks like this…



Temps today will hang in the 30s as the light snow moves away. Tuesday will see clouds and sun and I can’t rule out just a touch of mixed precip as temps warm to the upper 30s. The snow on the ground is going to play a big role in temps over the next several days as temps will stay much colder than areas to the west that don’t have snow. This setup will play a role by Wednesday and early Christmas Eve Day as moisture streams in from the west ahead of a big storm. This may allow for some frozen precipitation during this time and that’s something we will be watching for the next few days.

The first storm will head up just to our west and this means milder air takes over switching any mix to rain for Christmas Eve into early Christmas Day. Here is the GFS…

Christmas Eve


Christmas Day Evening


That setup would mean falling temps all day long on Christmas with some snow likely in the air before the day is over. You will also notice another low developing across the east coast and that’s something to watch for. The Canadian model looks similar and is showing this second low taking over…



In the wake of this low… MUCH colder air moves in for next weekend and there is energy diving into the base of the trough that would try to develop another storm by late weekend or early next week.

The pattern to close out 2009 and usher in 2010 is loaded with an active southern storm track and an increasing amount of arctic cold that will enter the US. We have seen these two mixing it up already for a lot of the country, including right here at home. We aren’t even close to being finished as the best is yet to come.

Have a great Monday and take care.
