Chase Possibilities Returning Next Week

The long-range GFS and ECMWF have been hinting at the possibility of a high-amplitude long wave finally breaking down the blocking ridge over the central CONUS. The wave's timing has been varied between the two models, with the GFS wiffle-waffling it between 200 to 240 hours out (essentially fantasy land). Moisture also seems like a possible concern with a cold front progged to go crashing through the central/southern Plains this Friday with another stronger front coming at the start of next week. At this point, even a whisper of a fall season is appreciated though.
