How we verified this(8)

every temperature taken from that town own Met Office forecast page, and all four town URLs are carried in the source note so each number is traceable
the Met Office regional maximum of 23C is the hottest-anywhere figure for Wales and matches none of the four towns, so it is left out; the prose says the three towns reach 22C rather than that they share the day high, because Monmouth reaches 23C today
rain timing follows the Met Office wording, which puts the rain in from the evening and overnight with some of it heavy, not heavy rain arriving overnight
no warnings claimed; the warnings feed returned no items and the warnings map showed none for Wales through 9 September, re-checked at 07:20
flood position read from Natural Resources Wales, 0 severe warnings, 0 warnings, 0 alerts, page updated 07:20 today
the index tiles on the Met Office regional page read a degree below each town page; settled against Monmouth and Aberystwyth, which match their own pages, so the labelled town maximum is the figure used
no clothing or planning advice carried, because the forecast supports the conditions but not the inference
