UK long range weather forecast

Initially predominantly dry with large sunny spells away from the northwest where cooler, cloudier and wetter conditions are most likely. Though there will be a few isolated showers further south at times. Becoming very warm again in parts of the south before the weekend introduces a more widely unsettled and showery period including risk of thunderstorms - though still some good sunny spells and temperatures around or just above average for most. Toward the end of the month uncertainty increases, but potentially returning to a drier, settled and warm period, in the south especially.
