Interesting it shows an AK vortex but still ridging over the west coast. Probably because it is pos tilted. Orientation matters.

Yes, a trough over Japan is always preferred!

It's early! But definitely intrigued by next weekend. Compared to say, Tuesday, it is looking like a little better chance for the DC area. It's not perfect but again, it is a week out it doesn't need to be yet. Pattern wise definitely like that both -NAO and a 50/50 low are showing up in a lot of the modeling. Again, not perfect...the west could be a lot better and NAO could be more west based...but these are both features we are lacking with Tuesday so them showing up is a good start. Also of note is the Southern Oscillation Index, or SOI. One of my college professors loved the teleconnection that a sharp SOI dive was well correlated with East Coast storms. Well the SOI is forecast to take it's sharpest dive in at least 4 months around next weekend. So something interesting to keep an eye on!
