It's likely to be generally dry though John, at least over the next week. I wrote my post yesterday (Tuesday), so it was yesterday's 00Z runs that I was referring to. Those runs were indicating the likelihood of a strong E or NE flow across at least the south of the country. Since then, the models have tended to place the controlling High further south, so that things now look much more promising. It looks as if by the weekend and into next week most of the country should have a fair amount of sunshine by day and light winds, which should make it quite pleasant, though perhaps still with some frosty nights.

No agreement means my confidence about the anticyclone persisting until next weekend is not high enough to forecast it. MetO holds a similar view in its 6-15 day precis. Personally, I find the decision to introduce a 16-30 day forecast bizzare. Is there an explanation of the reason and the methods they'll use to make this forecast? Maybe they are on the site and I've missed them and sorry if I have. Please direct me to it if you've found the rationale. In addition, is it going to be monitored for any accuracy? Will anyone actually remember what was forecast, on a daily basis, a month ago and will anyone care? |

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. 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.

I stand by it still. And I'll stick to the SST anomalies keeping it down south for the most part. Mind you, the anomalies are said to have less effect during the summer so that may be some small crumb of comfort. -- Graham P Davis, Bracknell, Berks., UK.
