The Return of the Rain

The warm weather abruptly ceased yesterday as the first measurable rain for 11 days occurred. The heaviest rain fell before 0900 UTC and was accredited to the previous day. Generally, amounts of rain in the London area were fairly small, with the more persistent rain occurring over counties to the north of the Capital. Further heavy rain is forecast, but looking through the records for south London during the last 20 years, high rainfall totals are not particularly common. There have been only 10 days during May with rainfall above 15mm. The wettest May day, with 24mm, occurred on the 27th last year.
