Default High pressure, or an Atlantic breakdown at 10 days? Take your pick.

After the changing output of the last 36 hours, we're in a period of
real uncertainty towards mid-month. The MetO says this:

"From Monday (15th) until Friday (19th) March the weather becomes much
more unsettled with wind and rain in many western parts spreading
slowly southwards. Temperatures cold at first but near normal later."
It then continues this forecast in a similar unsettled vein past the
end of March on the 15-30 day forecast.

The 12z ECM shows high pressure dominating, whereas the 12z gfs shows
something more unsettled.



Neither the 00z gfs, nor the 00z ECM were outliers in terms of
temperatures compared to the ECM mean and neither was the 12z gfs
operational, compared to the gfs ensemble mean:

A slow warming trend is likely, but would anybody like to take a
position on the synoptic situation at 10 days?

So in March you will go for the slow warming trend.

Brilliant absolutey brilliant.

He can only report what he thinks is likely to happen,
and if what he thinks is likely to happen is similar to
long term trends, then so be it.

You understand nothing about the possible uses of weather model
information at 10 days Lawrence either. Try forecasting at that
distance a few times before saying anything to someone that is
prepared to put their neck on the line time and again to do exactly
that. Also - try to avoid abuse in your replies from now on, no matter
how difficuilt it is when you have little to actually say. So far
tonight you've called SRH a GW nutter and me a tw+t. More abuse coming?

A wonderful piece of gibberish! What I gather from that is that there
will be no change from the 15th to the 19th with wind and rain limited
to the west throughout.

True! I'd just like to point out that I didn't actually write that!

Presumably either "western" should have read "northern" or "southwards"
should have read "eastwards". Maybe it originally said "wind and rain in
many western and northern parts spreading slowly eastwards and
southwards", but some editor decided that it was too long and made a
ham-fisted attempt at shortening it.

No Col I was being charitable the way he (dawlish ) sticks his neck out and
to hell with it, even if the odds are in his favour, he nails his colours to
the mast. Been a trait of his all winter. I paticular like his long range
prediction that there could be some rain in the UK during the winter months.

Well, yes indeed.
And he is quite open and honest about it with the 75% confidence
level to forecast at 10 days.
Presumably he considers anything lower than that wold merely be
'guesswork' and he'd get as many forescasts right as wrong, so
what would be the point?
