Long term that AK vortex is a killer. It will try to flood zonal pac air across the conus. It can be fought off sometimes temporarily if you have good atl blocking but even then it’s a struggle. But oddly enough a lot of our snowstorms feature a trough near Alaska. That’s because there is a lag effect of several days to a week before that feature kills us. But in the meantime the short term effect often opens up a window of opportunity here if there is some atl blocking. As the ridge response to that AK vortex crashes into the west coast often there is a temporary downstream trough in the east under the blocking. For a short time it actually can favor something amplifying along the east coast. It won’t last, that’s why a lot of our storms are followed by a warm up not long after, but there is often a short period of opportunity as that AK trough sets up before the pattern goes to crap.
