Despite some people seeming to believe this has been a cold start to May, the statistics prove it has been a rather warm one. This is likely to be due to high minima more than any notable day time warmth. There has been heavy cloud cover overnight in many areas- in fact the temperature hardly dropped at all in these parts last night and many places remained in double figures. This could again be the case tonight and tomorrow night. I think this is evidence of the fact that those who estimated a high CET for this month are justified, for the moment at least. As May progresses, cold spells that could dent the CET are obviously going to be less likely although not impossible.
