Christmas Snow Update

The Bering Sea Rule

Some forecasting techniques never cease to amaze me. I began watching for the potential of winter precipitation around the 23rd to 25th on December 4th. I used a technique called the Bering Sea Rule, which basically states that weather patterns over the Bering Sea could potentially impact the United States some days later.

These results speak for themselves. The BSR sniffed out the potential of southern storms in the united States about 20 days ahead of time. While this may be more of a rain event, it still displayed a patter conducive to winter weather.

Christmas Snow Update

On to the forecast though! It seems that a majority of the models are on board with some form of light snow falling between Saturday and Sunday night. Some models have accumulating snow, most do not, but there’s still certainly a chance for a light coating of snow on Christmas morning. However, the best chance as of now is north of the Ohio River.

I’ll continue to watch the data come in over the next several days and keep you posted! Have a great afternoon!
