I think it has updated, blue is pretty dry and also temps. looking much better for final week. It is the trend that is important. I live in Ireland and West is best, for the moment anyway, also it is consistent with Met office forecast.
Both wrong, example, Northern Ireland is shaded red, which is 75% of normal rain fall for the period 12 to 20 May, then look at the top chart and you will see blue shading for that period, "precipitation as % of normal during the first period"
The problem is trying to spot the change in a particular trend. The models are hinting that a change will happen and so we can hope that they will be right at some stage.
