Well that's a decent look for a few reasons. Let's break down the positives
1. Jet streaming across the pacific ends up breaking off, with storminess/moisture moving through north Mexico
2. That storminess takes on a STJ look, with storminess accompanying that jet streak across the south and mid-atlantic, which will obviously lead to an active weather pattern of some sorts
3. Ridging over west coast (+PNA) must lead to a trough on the downside of that, which could get caught up in the jet streak
4. There's some low pressure around Newfoundland, and high pressure ridging south of Greenland, all of which could help lead to a "blockier" scenario
Let's break down the negatives
1. The western ridge isn't in the most ideal position, with the highest anomalies being just offshore the west coast
2. High pressure isn't anchored in southeast Canada, which is arguably the best spot to reinforce cold air to meet up with this stormy look
3. Due to the ridge axis being right off the west coast, the trough would likely be over central US, giving a chance for heights to rise along east coast. That would help us avoid suppression, but *could* lead to some inland/coastal huggers if this look were to verify
