Week 1 Blowtorch
Week 2 near to slightly above normal.
Week 3 same only cooler than normal to the north and west
Week 4 same
Week 5 and beyond dartboard.
One thing that is consistent, it gets cold out west and stays that way through the duration.
I couldn't find climatology for thickness records, but 500mb heights I did find, and that would have been near historic. The lowest heights I found for Melbourne was 544dm and 550dm for Miami. This was 547 and 550 exactly.
Long range storms at least signify potential. When you are consistently showing nothing, the signal is for a pattern to produce nothing. It isn't just the GFS either, but the GEFS/EPS also are coming up with nothing through their runs.
