Review & outlook
Back | HomeThe weekend went as forecast—-cloudy with warm front on Saturday, showers on Sunday. I probably should have mentioned something about the cloud base lowering through Saturday and accessory clouds below the main cloud deck.
Sunday was interesting as a small jetstreak crossed the country, leading to enhancement of the showers on one side and their suppression on the other, giving a some soaring for a while (e.g. at Booker). This was forecast ahead of time, but what with being at the BGA conference on Saturday and taking forever to find a petrol station in Banbury (are they illegal there?!) on the way home, I didn’t get the chance to do an update. That said, pretty much everywhere got a shower at some point on Sunday, and all the forecasts for both days leading up to the weekend were correct. (Amusingly someone said to me last week “[we] can’t predict the weather”! Erm, yes we can
.)
Early Outlook
Tomorrow (Tuesday) sees more cloud and rain clearing to a brigher afternoon, 15 knots southwesterly wind. Wednesday will be a brighter drier day, and would probably be quite nice if it wasn’t for more strong winds coming in. They’ll be a little less that Monday morning, and will be strongest in the top of the forecast area, with the south being comparatively calmer, but still seeing some 25-30 knots westerly.
Thursday will be the best day for a long while, bright with less wind than of late, and the strong possibility of wave over Wales. Friday however sees it all going back down the Gary Glitter with yet more rain, possibly from a rather persistent stationary front.
The GFS differs significantly from the Euro models for Saturday but none look exactly great, all being variations on the theme of cloud and damp. There’s too much variation between the models at present to write a forecast for Sunday.

got any more details on UK RASP upgrade?
Sure—the existing UK RASP computer is a P4 3 GHz, but Paul’s obtained a new Q6600 to replace it. That’s a Core 2 Quad, with 4x2.4 GHz processors. Testing has already shown that it does almost four times as many calculations in the same time as the old P4 did—it does the UK 12 km grid in 40 minutes, compared to two hours previously!
Paul’s not decided how he’s going to set up the new system yet, but in any event it’s going to be a big improvement over what’s already available.
