I have just updated the 5 Day Forecast on the website. Below is the 00z GFS valid at 6pm Saturday, it forecast for the southern storm to be a little stronger before phasing into the northern storm system. I have put the forecasted track of both storms to where they both phase into one big storm.

As for the White CHRISTmas, the chance is up to a 30% as there is another storm system forecasted to develop and swing south of us. So, after 10-20 years of Brown Christmases could we finally have a white one? We'll will see.
