A split set up with cloud and rain through the north and western counties - ahead of this more cloud. Brighter with warm sunshine in the south-east and highs of 25C in Kent and 24C in London, making for the warmest London Marathon on record. A chance of rogue downpours in the south-east later - mostly through East Anglia. Elsewhere skies clearing to a better. clearer end to the day but it'll be cooler.
