"The 00Z GFS ensemble quite
strongly suggests that there could be a brief cold spell starting as
little as 11 days away, though it doesn't look like lasting for more
than a few days.

But of course it's not there on the 12Z.

Just more fantasy

I don't bother looking more that a few days ahead, complete waste of time &
effort!!

Why is it these models can only predict mild conditions 5 to 8 days ahead
but are totally useless at predicting cold conditions?

I really don't know why anyone bothers unless of course they are looking for
a zonal winter, which this could quite well end up as one
