Here is, in my opinion, one of the big pattern keys to keep an eye on. Going to use the GFS as an example. Look at yesterday’s 18z gfs. It cut off the pac energy and retrograded it west under the building epo ridge out west Now, the newer run still building an -EPO ridge, but they’re also bringing that pac energy east which temporarily boosts the SE ridge. If this ends up happening we may have to wait another 7-10 days to let the -EPO work its magic .
