LATEST DEVELOPMENTS:
The latest weather maps show further slow-moving areas of showers in places on Friday.
Net Weather forecaster Nick Finnis said: "We saw some warmth earlier in the month, thanks to warm air moving up from Africa, culminating in 21.8C being reached on 13th at Writtle near Chelmsford, Essex – the warmest day of the year so far.
"However, it’s turned colder during the second half of this month, with northerly or northwesterly winds bringing cool days and some chilly nights.
"But it has, at least, turned drier as a result, despite some showers earlier this past week."
