some of these short waves are digging pretty far down and then bouncing north due to the southeast ridge. I can totally see some of those depictions. Are they correct? I don’t know, but completely realistic imo. We’ve had all types of scenarios last few years when everyone was claiming this or that will save us only to find a way for these waves to dig into the plains and create messy scenarios.
Also, these air masses are not arctic. Low 30s for highs with sun? Only thing saving us is high pressure trying to anchor in.
