Ibulieve that March will continue dry until mid-month with increasing amounts of sunshine, and mild. Then we'll get the odd northerly outbreak from time to time, but from the NW, with showers and sunshine, so still qutie bright, and a very average CET (around 7.0C) I beleive.
April, an unsettled and thundery month, and mild at times, cold at others, maybe some snow in upland England at times. Average overall (9.0C CET). Rainfall prolly average. A month of much hail.
Ibulieve that May will probably see some alternating warm, then cooler periods, with showers or general rain at times, with the odd rumble of thunder in the midlands and of course Manchester. Highs reaching 30 degrees in Manchester in the final week, and 25-28 degrees in other places.
Ibulieve that June could be quite poor after a decent May, with a lot of rain and especially thunderstorms, and quite cool, with average highs over the midlands of only 18-19C, a CET of only 14C or so, so cold. Could be sunny at times with cold nights, most rain being convective and showery in nature. So, a northerly sunshine and showers regime. Average sunshine. Rain 120-130% of average.
Ibulieve that July should be a decent month. Reaching 31 degrees, here in Manchester, and 33 in the SE in one or two places. Avg highs of 24 degrees in the midlands, 26 in the south, 24 in Manchester, with 250 hours sunshine. Anticyclonic conditions positioned to draw warm air from the central european continent and even the mediterranean.
Ibulieve that August will finally be the summer month it has not been for the last seven years. Very sunny with a mean temp of 15-16C or so, with high daytime temps but rather cool nights at times. Manchester reaches 29C. Apart from the thundery June it will unfortunately be a rather calm unthundery summer, with no storms in July and August. That's all, folks!
