This Evening and Tonight:

Mostly cloudy during Monday evening, with this low enough to produce hill fog over the mountains and the odd spot of drizzle. A few clearer spells emerging into the early hours of Tuesday. A warm and rather muggy night. Minimum temperature 13 °C.

Tuesday:

A grey and murky start as low cloud lifts. Outbreaks of rain arriving through the day, turning heavy over the hills. Hill and coastal fog returning by evening. Feeling humid. Maximum temperature 20 °C.

Outlook for Wednesday to Friday:

Unsettled at times over the coming days with showers and spells of rain. However, some drier, warmer and brighter interludes are possible too. Remaining humid.

There is the possibility of some very warm and humid weather across parts of south and southeast Britain at the start of this period and perhaps the chance of a few thunderstorms too. Generally more changeable to the north and west at first, but there is a signal for high pressure to build more widely as we move towards the latter part of June. This likely brings more widely drier, settled conditions with temperatures probably remaining above average for most. It is still possible that Atlantic low pressure may still bring brief spells of wet and windy weather. There is a chance that the hot conditions, could return northwards accompanied by a thunderstorm risk; this all dependent on the orientation of the aforementioned high pressure.

High pressure is expected to lie close to the UK at the start of this period, bringing mainly dry, settled weather. Temperatures will likely be above normal, with the potential for hot conditions, accompanied by occasional thunderstorms, especially in the south. Into July, the influence of high pressure may weaken or shift more to the north of the UK. This leads to an increasing chance of periods of unsettled weather, either in the form of Atlantic low pressure systems moving in from the west or thunderstorms developing more widely compared to the start of the period. Temperatures will probably return closer to normal too, although some warm and humid spells remain likely at times.
