Zonal flow aloft is expected to persist into late next week across the CONUS. The upper-level jet will be displaced northward to near and along the Canadian border. As successive shortwave troughs move through that zone of stronger flow, cooler/drier air will move southward into much of the Plains and parts of the Midwest/Northeast. By next weekend, there is some potential for some upper-level flow amplification with a ridge developing in the West and shortwave troughs moving into the eastern third of the CONUS. However, models remain rather divergent in their exact depiction of this evolution (the ECMWF deterministic/ensemble is more amplified than its GFS counterparts). Further increasing uncertainty, the degree of moisture return ahead of any potential shortwave trough is questionable given the expected frontal progression to along/near the Gulf Coast.
