By Tuesday, parts of north and west Scotland and west Northern Ireland could see temperatures creep above 20C (68F) once more.
On Wednesday, while warm again for most with sunshine, some cloud will temporarily come into eastern Scotland and eastern England, with temperatures falling to a cooler 9-13C (48-55F).
Later in the week parts of England and Wales could see highs of 20-22C (68-72F), and with less of an easterly breeze, it won’t be as cold as it has been on North Sea coasts.
A cautionary note for gardeners and growers though, while daytime temperatures climb well above the early April average of 10-13C (50-55F), the nights will still be chilly.
Many areas outside of town and city centres could be susceptible to a light frost early in the week.
