The next week continues to grow more complex. Many of you have seen the Winter Weather Advisory that the Pittsburgh NWS put out yesterday. It started with 4-6″, the 3-5″, now it is down to 2-5″. I am sticking with my original call of 1-3″. But, don’t be too disappointed as an early morning Christmas day swatch of snow should bring us additional snow and I think by noon on Christmas day Pittsburgh has 2-5″ of snow on the ground. Considering the low probability Pittsburgh has for a white Christmas based on our history that isn’t too bad. I have 90% confidence that we will see a white Christmas in Pittsburgh this year.
A couple of different scenarios are worthy of your attention later next week. One scenario shows a monster storm, capable of dumping 16-24″ right up the west side of the Appalachian Mountains From Wed-Thur. The second scenario shows a smaller system on Wed and a larger system on Friday, for a total of 12-18″ of snow. My take is that we stand a fairly decent shot at getting a foot or more of snow mid-late next week.
I will do my best to provide updates amidst the holiday festivities. Safe travels if you are on the road this weekend and bundle up!
