The GFS has a weak shortwave in the southern branch of the jet affecting the plains on Monday of next week, when it appears as if we transer into a progressive pattern with southwest flow over the plains once again. That will be absolutely great if it happens. This is peak season and there is still a lot of time left, but the clock is ticking.
I don’t want to go over details this far out, but by going off the GFS Monday’s setup would have tornado potential with very high instability and moderate deep layer shear. It would be a classic triple point dryline setup as well, which I love to chase the most.
We’ll wait until the 12Z comes out and see what it has and I’ll take a look at the European, but even if Monday doesn’t turn in to a chase day at least there are some signs that the upper air pattern is about to change.
I will post again later as soon as the new data comes out.
