**At T240, on 25th August, a large and persistent high pressure system will be located over Scandinavia/Baltic sea. It will lead to one of several types of weather for the UK, depending upon its exact location and orientation, but low pressures will be stalled in their passage across the UK from the west. If the stall occurs with the low centre over the UK, some areas may be experiencing heavy rain and flooding may well result in some areas. If the high is a little further north, dry easterlies will be affecting the UK and if the lows stall further to the west, with the high pressure itself a little further west, warm air from the south will be drawn across the UK.**

Thus, very difficult to predict the UK's exact weather, as a small change in location of the centre of the high could lead to a large change in our weather type, but high pressure will have become firmly established to our NE by the 25th.

This is a forecast for Scandinavia though,

True. It's s forecast that high pressure will become established to our NE in 10 days. Wish I could be specific about the UK weather, but it's not possible.

So can I assume that if this forecast verifies (for Scandinavia) it won't count towards your success rate for UK forecasts?

Do I have a success rate for UK forecasts?
