Saturday December 16

Are you ready for a little warm up? I think we thawed the issue on this web site and I apology for the multiple crashes on Friday. The issued should be resolved for now. As for the weather, we had a good start to our snow season and I will have a snow recap later today. But the snow will be melting and perhaps a little rain on the way Sunday. The jet stream will be relaxing for a bit, but come charging back within a day or two of Christmas. There is a little debate on the timing and since it is 9 days away, I will contrast the two main opinions below.

Note: Baltimore’s BWI recorded 0.7″snow Friday.  The city and Hartford County recorded between 1 and 2 inches. I will have a snow report later today.

The Jet Stream will relax this week and then surge back with colder air around Christmas. The debate is will it be on Christmas or a day or two later? There will be a storm marking the boundary…

This is the European Model… showing the return of cold air by Christmas.


Christmas Eve Jet Steam:


The GFS Model holds the cold air back a day or two later…


Christmas Eve Storm?

There will be a storm along the boundary and the GFS shows the snow and mix just to our north. This is 9 days away so I will not lock in to the timing location of this plot. 


Temperature Outlook

We will see temps between 55ºF and 60ºF this week. But notice the timing of the cool down. It will get cold agin within a day or two of Christmas.





We can promise all apparel orders in by midnight tonight will be delivered before Christmas.
