NW Scotland appears to have been very wet at times in 2011, especially in May and again in September-October 2011; witness the very high monthly totals at Cluanie Inn in Wester Ross for some of the months of 2011, and the correspondingly low values at sites in central or eastern England, at http://www.climate-uk.com/page3.html
Of course so far this month it has been very dry in parts of the extreme north of Scotland, and North Scotland has also had the highest temperatures at times, with Scotland breaking its record values for both March and May. Incidentally I have heard the 29.3 deg. C. at Achnagart in Wester Ross on 25th May, although it is on the Met Office website, questioned; even if this is discarded, the next highest temperature of 29.0 deg. C. at Cromdale in NW Scotland still seems to be a Scottish May record, as the Monthly Weather Report for May 1992 gives 28.9, not 29.0 deg. C., at Edinburgh on 14th May (although the highest given for Britain that month was 29.5 deg. C. at Barbourne in Worcestershire on 20th May.
My own feeling though is that sometime this summer the normal pattern will reassert itself, with warmer, sunnier and drier weather in the south and east and duller wetter in the north and west - it nearly always does, although perhaps not if there is a repeat of the summer of 1968 which was better in relative terms in the NW compared with the SE. Northern Ireland had its sunniest summer on record up to that date, although subsequently there were a couple of sunnier ones (1995 and I think 1975); in August 1968, the sunshine values in the Outer Hebrides were about 8 hours/day compared with about 4 hours/day in parts of the SE. March in 1968 of course had a very warm spell at the end, as happened in 2012, but of course this does not necessarily mean that meterological history will repeat itself this year.
