Last, 6Z GFS has huge dome from the S.Plains to the S.Cornbelt, eastward, with 100+ temps. Outlier???

Operational GFS continues to be the most bullish with the week 2 dome dominating much of the country. Latest 12Z GFS below:

WOW! I'm not sure what to think about the extended weather.
The last 12z European model has an upper trough in the Midwest early in week 2, then a mega dome at the end of week 2:
Mike,
I assume you realize that the 360 hour European control is near useless as it has next to no forecast credibility. As you even said yourself, it jumps around wildly from one run to the next. So, it has little value and is not taken seriously by any forecasters I follow. All it is is a low resolution version of the unperturbed initialization of the operational model. It is essentially just one run of 52 members of the Euro ensemble. It is slightly less bad than each of the other individual ensemble members since the others use perturbed initializations, but that's not saying much. I mean the 360 hour Euro control map is no better than a GFS map at 360 hours and we know how little value they have as they jump all over, too. The Euro control may even be worse due to the low resolution. For 360 hours, I'd much prefer to look at the GFS and Euro ensemble means though even those have pretty low credibility that far out in time. NG doesn't care about as the market is currently down.
Excellent points Larry!
However,
The ensembles have the heat ridge much farther west.........but the 8-14 day has alot of below normal temps closer to the heat ridge and above temps along the East Coast.........where the ensembles have an upper level trough.
It's just not matching up. Recent operational GFS solutions have shown the heat ridge similar to this last European control model but without much support from the individual ensembles.
One thing that looks likely is that there is more rain in this forecast than there was last week.
