Maybe the OP runs are having feedback issues that the ensembles do not.... I don't know.

Better than the GFS.

So far the ECMWF looks way better than the GFS.  You can see the GFS is domed to fail by day 5 while the ECMWF is far better at days 5 and 6.

Pivotalweather.com has ECMWF precip maps.  Have to go under ECMWF high resolution maps.

There is less snow through day 7 on this run than the last couple runs.   Pretty unimpressive.

850s are solidly cold with northerly surface gradients on the Euro at day 7.  Pretty nice.

At least that's more than a week out.  Time for it to change.  That could still work out too.
