a frosty start in some areas on the 25th, but some sunshine for most, albeit with showers clipping far eastern and far western coastal counties for a time. The 26th saw bands of showers from the north Midlands southward to start the day, these sweeping south-eastwards, coalescing for a time into longer

for other UKCP Probabilistic variables. Clipping of the pdfs and cdfs is also performed, to remove extreme values that may be less physically plausible than those within the bulk of the probability distribution. Reduced confidence in such tail values may arise, for example, from enhanced sensitivity

and figures in the headline findings  to reflect these improvements. In response to some user queries, we’ve also published a new technical note clarifying characteristics of the probabilistic projections data such as the clipping at the extremes ends of the distributions and non-zero sum of anomalies during the baseline period.

than those within the bulk of the probability distribution. Clipping is applied at 5th and 95th percentiles. • While not a limitation, it is important to note that in summer, 1-day precipitation at 50-year return level remains close to the baseline while other UKCP products show a significant
