A cloudy and murky start but turning warm and sunny.
Today:
Cloudy and perhaps misty for many at first, though cloud will soon lift and break to leave warm sunny spells into the afternoon. Breezy, especially around hills, at times. Maximum Temperature 21C.
Tonight:
Some late evening sunshine before low cloud, mist and fog returns from the east overnight. This will stop temperatures dropping too low leading to a mild. Staying breezy around hills. Minimum Temperature 11C.
Outlook for Saturday to Monday:
Mostly unsettled over the weekend and next week with heavy, possibly thundery showers and longer spells of rain at times, mixed with sunnier intervals. Feeling warm and humid.
UK Outlook for Monday 23 Sep 2024 to Wednesday 2 Oct 2024:
Showers with the potential for some longer spells of rain, heavy and perhaps thundery at times, will affect parts of England and Wales at first, especially in the south but tending to ease away to the southeast by the end of Tuesday. Elsewhere, generally settled conditions prevailing, albeit with low cloud and drizzle along North Sea coasts in particular; away from here, most places will experience above average temperatures during this period. A short-lived quieter spell of weather is possible then possible, before a transition to a more unsettled, mobile westerly pattern is most likely by midweek and beyond, with spells of wind and rain in many areas, but perhaps interspersed with occasional drier and brighter interludes.
