Would any SGMer critique the consensus forecast?

Which consensus forecast?

I only had a moment to glance at the page, but the jet
stream forecast box only had an "archive" that provided
a clickable link. *Can you direct me to the forecast?

So far, I can't find the consensus forecast. *I am sorry for
the confusion I caused.

However, I found the following to give the (current) status of
the jet stream -

I will check government climate center etc. for more on jet stream.

I agree with Darth, the details of a day 7+ forecast, even for
something as large scale as the jet stream, are iffy. Sometimes
even the overall pattern is significantly wrong. At that sort
of time range, the general features of a time mean forecast like
http://www.cpc.noaa.gov/products/pre...0day/500mb.php
are more reliable, but still generally not perfect (although I
did score a 0.98+ anomaly correlation once). Overall the recent
6 to 10 day outlooks have looked reasonable compared with patterns
I've seen in the past, with the ridge forecast over AK looking
strong enough to be consistent with supercritical flow over the
top that could cut a trough back over CA, but since I left CPC I
don't have access to some of the tools I'd used to use to make
such assessments. I notice that today's 6 to 10 day mean 500 mb
forecast flattens the ridge somewhat compared to the past couple
of days, FWIW.
