Disagree strongly. You can get an amplified storm with only the northern stream. The PNA gives you the track you need for a coastal and the NAO both prevents a cutter and slows down the flow to allow storms to amplify.
what we have been missing lately is both the storm track and a blocky flow which allows storms to amplify. This pattern provides that, northern stream or not.
Sure we may not get an east coast QPF bomb without some help from the STJ, but we can absolutely see a prolonged period of moderate to higher end events with this pattern.
everyone on her know I have no bias when it comes to weather, I’m calling it how I see it.
