Another day like yesterday in prospect. 8C for Will on the hill

temperatures here rising quickly and we're much more likely to breach
double figures today than he is.


We'd better make the most of it. Today's 00Z model runs are not at all
encouraging for the next couple of weeks, as you've no doubt seen.


Back to sparkling weather down here John. It'll be cold in the south-
east, but many UK areas away from there have a potentially gloriously
sunny and dry week in prospect.


Yep. But my post that you've quoted is now two days old. so it's not
surprising that things have moved on.



However, out at 10 days, the position of the jet is finally forecast
to change. It's only a chart forecast *ATM, but the ECM has also
picked up on a potential fall in pressure, on some recent runs, as
Atlantic weather threatens again. the 12z gfs shows the possibility of
the return of that absent beast, the Azores High, to its more usual
position. Now if would just ridge towards us please...........


Fingers crossed.

12z ECM begins to go for an Atlantic breakthrough. It'll be
interesting to see the 00z ens on this one. Yesterday's 12z ens were
showing a mean warming trend to 16 days and a change to wetter and
windier weather after about 10 days. If a pattern change is in the
wings, would imagine the 00z ens would reinforce that. 00z gfs ens
show a similar mildening, but the operational, with high pressure in
charge, is very close to the mean at 10 days.

I suspect a pattern change is coming around, or just after, mid-month,
to much more mobile, Atlantic weather, but the gfs jetstream forecast
doesn't go with the changes it suggested yesterday. See how close this
gfs run is to the ens mean.
