: Clipping and baseline advice on Land Strand 1 data in UKCP18 (March 2019). The Probabilistic Projections were updated in August 2022, and there may be some small changes to the figures within this document. Please refer to the table above for the latest documentation for the Probabilistic Projections

, Wales, and much of Northern Ireland. This means dry, sunny, and increasingly hot conditions for many. However, the northwest of the UK, particularly western Scotland, has drawn the short straw, with frontal systems occasionally clipping the edge of the high. This brings more cloud and some light rain

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

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
