Friday Evening Update

Good evening, folks. With a well behaved half and half weather weekend ahead of us, we are focusing on the Christmas weekend forecast and the potential for some winter weather.

Look, every single computer model run is going to change from run to run. That change may be quite dramatic, so do NOT get attached to any one solution. It doesn’t matter if it shows snow, ice, rain or absolutely nothing.

Still, it’s interesting to look at the various computer model outputs, if only for entertainment purposes. The European Model is all over the place, with the latest run being NSFW for winter lovers…

That run has a healthy swath of snow…

And ice…

The GFS also changes from run to run. It’s trying to show what the European is showing, but has more gaps between systems…

The one disenable trend on all the models is for a colder solution with less of a southeast ridge. Even the CFS is picking up on this. Check out the 5 day temperature anomalies in Celsius…

The GFS Ensembles also show a very cold look that continues through the rest of the month…

The same model isn’t shy about the winter weather potential during the same time…

 

One thing is for sure, this is going to be a very fun period of tracking the trends. We will see the latest trends with my overnight update. Make it a good one and take care.
