All models agree; it's just the consistency I'm now looking for. The

Are you sure? If anything the latest ECM runs seem to indicate it will
be more settled than it was looking a day or two ago! The deep low
later this week seems to be weakening, and the older two of the three
latest ECM runs indicate a high finally arriving for that time. Even
the latest ECM 12Z appears to show conditions no worse than this
weekend, and better than the last 10 days, for the south.

===============================
With Irene presently on the charts I would say that there is a lot more
uncertainty than normal. One may see inter-model consistency but that will
mean nothing since it will be the fine details of ex Irene's interaction
with the mid-latitude jet that will be key. I would say that no operational
global model yet has the vertical or horizontal resolution capable of
modelling that interaction accurately. Confidence has to be very low after 4
days.

Let's see what tomorrow's models show. If they are still showing
unsettled tomorrow evening, I'll be forecasting exactly that. I
remember your forecast for September/Autumn last year Will and it's
reliance on your knowledge of the interactions of extra-tropical
hurricanes with the jet. You seemed to know what would happen then.
I'm glad to see that you're now less sure. *))- Hide quoted text -

A NW flow around mid-Atlantic blocking on the 06z gfs. Cool and
showery. The deep depression is still shown to be affecting us at 9
days.- Hide quoted text -

Last night's appearance of high pressure ruined any consistency in the
forecast. Now we have divergence between the two models, gfs
suggesting the possibility of some blocking and ECM more unsettled at
10 days. No consistency and no agreement at present = no forecast.
